Deploying F5 BIG-IP HA into AWS GovCloud
This guide provides a walk-through for deploying an active/standby F5 BIG-IP High Availability (HA) cluster within AWS GovCloud (US) using the AWS Console. Code Repository: F5GovSolutions/f5-aws-cloudformation-v2-govcloud While the repository's examples/failover/GOVCLOUD-GUIDE.md handles the exact AWS CLI workflows, this document serves as the web console companion. The Partition Problem The upstream commercial F5 templates (F5Networks/f5-aws-cloudformation-v2) assume a standard AWS commercial partition. Pointing those unmodified templates at GovCloud breaks deployment for three distinct reasons: Partition Isolation (aws-us-gov): GovCloud uses unique ARNs, regional endpoints, and an entirely separate AMI catalog. Furthermore, CloudFormation mandates that a parent stack's nested templates reside in an S3 bucket within the exact same region and partition. CloudFormation cannot fetch objects across partitions, meaning all templates must be pre-staged in a local GovCloud bucket. Air-Gapped Realities: In isolated enclaves with no internet egress, a booting BIG-IP cannot pull the runtime-init installer or Automation Toolchain RPMs from public GitHub repositories or F5 CDNs. Everything must be hosted locally inside an S3 bucket, accessible via VPC Gateway and Interface endpoints. The 17.x Clustering Bug: On the BIG-IP 17.x code train, a startup-timing condition occasionally prevents the local device-trust domain (/Common/Root) from initializing properly on first boot. When this occurs, Declarative Onboarding (DO) cannot establish the trust domain or failover group, leaving both nodes deadlocked. This modified template embeds an automated, non-blocking self-heal script to orchestrate the recovery process without manual intervention. What it deploys The root template (failover.yaml) orchestrates a series of nested module stacks (network, access, ingress, application, and individual BIG-IP nodes) to build: An active/standby pair of BIG-IP Virtual Editions (VE) deployed across two Availability Zones using a 3-NIC topology (Management, External, Internal). Cloud Failover Extension (CFE) integration to re-map floating application IPs and AWS routes during a failover event. Automated onboarding via F5 BIG-IP Runtime Init, executing Declarative Onboarding (DO) for core network clustering, Application Services 3 (AS3) for virtual servers/WAF policies, and CFE for AWS API integration. The architecture uses Pay-As-You-Go (PAYG) marketplace licensing and is fully validated on the 3nic-payg...-with-app runtime-init configuration. Core Architecture Differences vs. Commercial Staged-Bucket Deployment Mode Because of partition constraints, your local GovCloud S3 bucket serves as the single source of truth. It must hold two types of data: the nested CloudFormation templates cloned from the repository, and the target installation binaries (the runtime-init .run installer and the accompanying DO/AS3/CFE RPM packages). The Unauthenticated 403 Pitfall CloudFormation reads your deployment templates using your active IAM user/role credentials. However, during the bootstrap phase, the individual BIG-IP instances download their configuration files and RPM packages over an unauthenticated HTTPS request. They do not sign these requests with AWS credentials. If your S3 bucket permissions block public read access completely, the instances receive an HTTP 403 Forbidden response, initialization fails, and CloudFormation rolls back the stack. Because GovCloud blocks public access by default, you must apply a scoped bucket policy allowing s3:GetObject to Principal: "*" paired with a DenyInsecureTransport block. Single-Toggle VPC Endpoints Isolated enclaves require four distinct VPC endpoints to function: S3 (Gateway) for fetching installation packages and AS3 WAF policies, and Interface endpoints for EC2, Secrets Manager, and CloudFormation APIs. Missing even one endpoint causes silent automation failures. To simplify this, the template consolidates these requirements into a single parameter: setting provisionS3Endpoint=true automatically provisions all four regional endpoints with private DNS enabled. Note that your bucket, stack, and endpoints must reside within the same AWS region. Automated Clustering Self-Heal To bypass the 17.x initialization bug without manual operator access, the template installs a localized orchestration loop during the pre_onboard hook. The mechanism drops three files onto the file system: cluster-heal.sh: The main orchestrator script. cluster-heal-trust.py: A native Python script that securely pulls the admin password from Secrets Manager via a SigV4 request using the instance's IAM role, then invokes the local device trust commands. /etc/cron.d/cluster-heal: A cron job that triggers the orchestrator every 3 minutes. This loop checks the cluster status. If it detects a missing root domain, it triggers a single controlled reboot, reads the peer node's address from the runtime logs, pulls the password, and establishes device trust. Once synchronized, it issues the CloudFormation success signal and disables its own cron job. This preserves DO as the declarative source of truth without creating configuration drift. During this process, the CloudFormation stack will remain in CREATE_IN_PROGRESS for roughly 25 to 30 minutes, which is normal behavior. Elastic IP Allocation Constraints The default AWS regional quota is 5 Elastic IPs (EIPs). Depending on your topology, this architecture can request up to 7. To prevent deployment failures due to exhausted quotas, use the template toggles to limit public allocations: Default Configuration (Public Mgmt, Public VIP, Public Self IPs): 7 EIPs Standard Air-Gap Profile (Public Mgmt, Private VIP, Private Self IPs): 4 EIPs Strict Isolated Profile (Private Mgmt via Bastion, Private VIP, Private Self IPs): 3 EIPs Verify your regional limit under Service Quotas → EC2-VPC Elastic IPs (L-0263D0A3) before executing the template. Deployment Steps (AWS Console) Before You Begin Select a single target GovCloud region (us-gov-east-1 or us-gov-west-1). Your staging bucket, CloudFormation stack, EC2 Key Pair, and Secrets Manager secret must share this region to prevent cross-region routing failures in isolated enclaves. 1. Provision the staging S3 bucket S3 → Create bucket, in your Region. Give it a globally unique name. [S3 Create bucket, Region selector highlighted.] 2. Stage the templates and artifacts While file uploads can be handled via the S3 web GUI, staging is more reliably managed via the AWS CLI from a local workstation. Installing the AWS CLI is outside the scope of this article but it's easy and instructions can be Googled. Execute the following commands from the root of your cloned repository to sync the template architecture and upload your pre-downloaded F5 binaries: Download commands: # F5 BIG-IP Runtime Init installer (note: this repo's tag has NO "v" prefix) curl -fL -o f5-bigip-runtime-init-2.0.3-1.gz.run \ https://github.com/F5Networks/f5-bigip-runtime-init/releases/download/2.0.3/f5-bigip-runtime-init-2.0.3-1.gz.run # Declarative Onboarding (DO) curl -fL -o f5-declarative-onboarding-1.47.0-14.noarch.rpm \ https://github.com/F5Networks/f5-declarative-onboarding/releases/download/v1.47.0/f5-declarative-onboarding-1.47.0-14.noarch.rpm # Application Services (AS3) curl -fL -o f5-appsvcs-3.56.0-10.noarch.rpm \ https://github.com/F5Networks/f5-appsvcs-extension/releases/download/v3.56.0/f5-appsvcs-3.56.0-10.noarch.rpm # Cloud Failover Extension (CFE) curl -fL -o f5-cloud-failover-2.4.0-0.noarch.rpm \ https://github.com/F5Networks/f5-cloud-failover-extension/releases/download/v2.4.0/f5-cloud-failover-2.4.0-0.noarch.rpm Sync and upload commands (be sure to be at root of the cloned repo), set the variables accordingly: # Synchronize the nested CloudFormation infrastructure templates aws s3 sync ./examples/ "s3://$BUCKET/$PREFIX/" --region "$REGION" # Upload the core runtime engine and toolchain extensions aws s3 cp f5-bigip-runtime-init-2.0.3-1.gz.run "s3://$BUCKET/$PREFIX/" --region "$REGION" aws s3 cp f5-declarative-onboarding-1.47.0-14.noarch.rpm "s3://$BUCKET/$PREFIX/bigip-extensions/" --region "$REGION" aws s3 cp f5-appsvcs-3.56.0-10.noarch.rpm "s3://$BUCKET/$PREFIX/bigip-extensions/" --region "$REGION" aws s3 cp f5-cloud-failover-2.4.0-0.noarch.rpm "s3://$BUCKET/$PREFIX/bigip-extensions/" --region "$REGION" 3. Grant anonymous read on the artifacts In the S3 Console, select your staging bucket and navigate to Permissions. Under Block public access (bucket settings), disable the option to Block public access to buckets and objects granted through new public bucket policies (leave ACL blocks enabled). Next, apply the following bucket policy to allow the instances to pull down the bootstrap packages securely over HTTPS: { "Version": "2012-10-17", "Statement": [ { "Sid": "PublicReadGetObject", "Effect": "Allow", "Principal": "*", "Action": "s3:GetObject", "Resource": "arn:aws-us-gov:s3:::YOUR-BUCKET-NAME-HERE/*" }, { "Sid": "DenyInsecureTransport", "Effect": "Deny", "Principal": "*", "Action": "s3:*", "Resource": [ "arn:aws-us-gov:s3:::YOUR-BUCKET-NAME-HERE", "arn:aws-us-gov:s3:::YOUR-BUCKET-NAME-HERE/*" ], "Condition": { "Bool": { "aws:SecureTransport": "false" } } } ] } Note: Ensure you replace YOUR-BUCKET-NAME-HERE with your actual bucket name. Do not include any trailing lines or comments in the JSON editor. [S3 Permissions — Block public access settings.] 4. Store the Admin Password Secret Navigate to AWS Secrets Manager → Store a new secret. Choose Other type of secret, select the Plaintext tab, clear the default JSON template, and type your raw password string. Name the secret (e.g., f5-bigip-admin) and save it using the default settings. Copy the resulting Secret ARN (arn:aws-us-gov:secretsmanager:...); both nodes query this specific object at startup. [Secrets Manager Store secret, plaintext tab.] [Secrets Manager: Name your secret.] 5. Create the SSH key pair EC2 → Key Pairs → Create key pair, download the .pem. The key pair is regional. This is optional but recommended you create one before template launch. [Screenshot: EC2 Create key pair.] (You can leave the parameter blank in the template and let the stack auto-create one, but then the private key only lives in SSM Parameter Store — pre-creating is simpler if you need to access the boxes vis SSH) 6. Confirm the BIG-IP AMI exists in your Region The deployment template discovers the target AMI using automated string matching. Ensure that your region has access to the target image by running the following lookup via your terminal, this can also be done via the GUI: aws ec2 describe-images --region "$REGION" --owners aws-marketplace \ --filters "Name=name,Values=*17.5*PAYG-Best Plus 25Mbps*" \ --query 'reverse(sort_by(Images,&CreationDate))[].[Name,ImageId,CreationDate]' --output table 7. Launch the stack (CloudFormation) Open CloudFormation, select your target region, and click Create stack (with new resources). Select Template is ready, choose Amazon S3 URL, and paste the direct object URL to your staged failover.yaml file. Configure the mandatory parameters: Stack Name: Define an environment-specific identifier. S3 Configurations: Populate s3BucketName and s3BucketRegion. Secrets Management: Paste your copied Secrets Manager ARN into bigIpSecretArn. Security Access: Set restrictedSrcAddressMgmt and restrictedSrcAddressApp to your administrative CIDR blocks to avoid exposing management interfaces. Air-Gap Toggles (For isolated VPCs): Change provisionS3Endpoint to true, and flip both provisionPublicIpExternalSelf and provisionPublicIpVip to false. In the options screen, consider setting Stack failure options to Preserve successfully provisioned resources during your initial test runs. This keeps instances alive for log inspection if a deployment fails. Acknowledge the CAPABILITY_NAMED_IAM prompt and click Submit. [CloudFormation Specify template — Amazon S3 URL field.] [Parameters page, air-gap toggles section.] [Review — Acknowledgement and Stack failure options.] 8. Wait it out Expect ~25–30 minutes in CREATE_IN_PROGRESS while the self-heal forms the cluster, then CREATE_COMPLETE. This is normal — it is not stuck. After 10 minutes, go ahead and admin SSH into the boxes, they should accept your admin secret by now, if not use your SSH key you created and referenced in the template. See the commands below or in the git repo guide. Validating the deployment From the stack Outputs, grab a management IP, then: Onboarding: grep -i 'All operations completed successfully' /var/log/cloud/bigIpRuntimeInit.log; the prompt should show failover01.local / failover02.local, not ip-x-x-x-x. Clustering: tmsh show cm sync-status → In Sync (green), Mode: high-availability, one node Active and one Standby. CFE: GET https://localhost/mgmt/shared/cloud-failover/inspect returns a populated object (instance, addresses, trafficGroup). The self-heal's own narration lives in /config/cluster-heal/log — the primary place to look if the stack runs long; you'll see the reboot → add-to-trust → creating failoverGroup → cluster In Sync → cfn-signal sent OK → disabling self-heal sequence. If clustering genuinely never forms (the rare case where the self-heal exhausts its attempts), the repo guide has a validated manual fallback that follows the same reboot → rebuild trust → reapply sequence. What's GovCloud-ready today — and what isn't Let's be clear about scope. The GovCloud template— staged-bucket defaults, the four VPC endpoints, the clustering self-heal, the bumped extensions — currently applies to one solution: the failover active/standby pair on the 3-NIC PAYG -with-app runtime-init config. The repo's autoscale, the quickstart standalone, and the other failover variants (2-NIC, BYOL, and the non--with-app configs) still carry upstream configuration and are not yet GovCloud-validated. Adapting them is planned work and would follow exactly the pattern documented here. And the self-heal is a workaround for an F5 platform bug, not a permanent fix. The right long-term resolution is the platform defect behind the KB; when a fixed build is in play, the self-heal simply stays inert. Where to go next The repo: F5GovSolutions/f5-aws-cloudformation-v2-govcloud Full CLI walkthrough (first-time operator): examples/failover/GOVCLOUD-GUIDE.md Parameter and architecture reference: examples/failover/README.md The self-heal sources: examples/failover/bigip-configurations/cluster-heal.sh and cluster-heal-trust.py If you're standing up BIG-IP HA in an enclave, start from the 4-EIP air-gap profile with provisionS3Endpoint=true, stage everything in one in-Region bucket, and let the self-heal do the clustering.

GRE and BGP are technologies that are... mature. In this article we'll take a look at how you can use AWS Transit Gateway Connect to do some unique networking and application delivery in the cloud. In December 2020 AWS released a new feature of Transit Gateway (TGW) that enables a device to peer with TGW via a GRE/BGP tunnel. The intent was to be used with SD-WAN devices, but we can also use it for things like load balancing many internal private addresses, NAT gateway, etc... In this article we'll look at my experience of setting up TGW Connect in a lab environment based on F5's documentation for setting up GRE and BGP. Challenges with TGW For folks that are not familiar with TGW it is an AWS service that allows you to stitch together multiple physical and virtual networks via AWS internal networking (VPC peering) or via network protocols (VPN, Direct Connect (private L2)). Using TGW you can steer traffic to a specific network device by creating a route table entry within a VPC that points to the device's ENI (network interface). This is useful for a case where you want to send all traffic for a specific CIDR (192.0.2.0/24) to traverse that device. In the scenario where a device is responsible for a CIDR it is also responsible for updating the route table for HA. This could be done via Lambda function, our Cloud Failover Extension, manual updates, etc.... The other downside is that this limits you to a single device per Availability Zone to receive traffic for that CIDR. TGW Connect provides a mechanism for the device to use a GRE tunnel/BGP to establish a connection to TGW and use dynamic routing protocols (BGP) to advertise the health of the device. This allows you to establish up to 4 devices to peer with TGW with up to 5 Gbps of traffic per connection (for comparison you can burst up to 50 Gbps with a VPC connection). Topology of TGW Connect When using TGW Connect it re-uses existing TGW connections. In practice this means that you are likely using an existing Direct Connect or VPC connection (I guess you could also use a VPN connection, but that would be weird). See also: https://aws.amazon.com/blogs/networking-and-content-delivery/simplify-sd-wan-connectivity-with-aws-transit-gateway-connect/ Configuring a BIG-IP for TGW Connect To use a BIG-IP with TGW Connect you will need a device that is licensed for BGP (also called Advanced Routing, part of Better/Best). Follow the steps for setting up TGW Connect and be sure to specify a different peer ASN than your TGW (you will need to use eBGP). The "Peer Address" will be the self-ip of the BIG-IP on the AWS VPC (when using a VPC). Configuring target VPC When setting up TGW Connect you will peer with an existing VPC. In the subnet that you want to use with TGW Connect (Peer Address of GRE tunnel) you will need to have a route that points to the TGW peer address; for example if you specify a CIDR of 10.254.254.0/24 for TGW and the peer address is 10.254.254.11 you will need to create a route that includes 10.254.254.0/24 on the subnet for BIG-IP peer address. Also make sure to open up Security Groups to allow GRE traffic to traverse to/from the interface that will be used for the GRE tunnel. The rule should allow the IP of the peer address (i.e. 10.254.254.11). Route to TGW from 10.1.7.0/24 GRE Tunnel On the BIG-IP under Network / Tunnels you will need to create a GRE Tunnel. You can use the default "gre" tunnel profile. Specify the same "Peer Address" that you used when setting up TGW Connect. You will also want to specify the Remote Address that is the TGW address. BGP Peer Next you will need to configure the BIG-IP to act as a BGP peer to TGW connecting over the GRE tunnel. TGW requires that you use an IP in the 169.254.0.0 range. This will require modify a db variable to allow that address to be used as a self-ip. The tmsh command to use is. modify sys db config.allow.rfc3927 { value "enable" } You can then create your BGP peer address to match the value that you used in TGW Connect. The BGP peer address will need to be configured to allow BGP updates (port 179). Since the traffic is occurring over the GRE tunnel there is no need to update AWS Security Groups (invisible to the ENI). Setting up BGP Peering TGW Connect requires eBGP to be used. The following is an example of a working config. This also assumes you go through the pre-req of setting up BGP/RHI. Be careful to only advertise the routes that you want, when you use "redistribute kernel" it will also advertise 0.0.0.0/0! Please also see: https://support.f5.com/csp/article/K15923612 ! no service password-encryption ! router bgp 65520 bgp graceful-restart restart-time 120 aggregate-address 10.0.0.0/16 summary-only aggregate-address 10.1.0.0/16 summary-only aggregate-address 10.2.0.0/16 summary-only aggregate-address 10.3.0.0/16 summary-only redistribute kernel neighbor 169.254.10.2 remote-as 64512 neighbor 169.254.10.2 ebgp-multihop 2 neighbor 169.254.10.2 soft-reconfiguration inbound neighbor 169.254.10.2 prefix-list tenlist out neighbor 169.254.10.3 remote-as 64512 neighbor 169.254.10.3 ebgp-multihop 2 neighbor 169.254.10.3 soft-reconfiguration inbound neighbor 169.254.10.3 prefix-list tenlist out ! ip prefix-list tenlist seq 5 deny 10.254.254.0/24 ip prefix-list tenlist seq 10 permit 10.0.0.0/8 ge 16 ! line con 0 login line vty 0 39 login ! end This example was created with help from a BGP expert Brandon Frelich. In the example above we only limiting routes to 3 CIDRs and configuring ECMP. At this point the BIG-IP could allocate VIPs on the CIDR, act as an AFM firewall, and if we used 0.0.0.0/0 it could act as an outbound gateway. Verifying the Setup You should be able to see your BGP connection go green in the AWS console and also see the status by running "show ip bgp neighbors" from imish. AWS Console ip-10-1-1-112.ec2.internal[0]>show ip bgp summary BGP router identifier 169.254.10.1, local AS number 65520 BGP table version is 4 2 BGP AS-PATH entries 0 BGP community entries Neighbor V AS MsgRcvd MsgSent TblVer InQ OutQ Up/Down State/PfxRcd 169.254.10.2 4 64512 293 293 4 0 0 00:47:08 3 169.254.10.3 4 64512 293 292 4 0 0 00:47:08 3 Total number of neighbors 2 Output from imish (tmos)# list /ltm virtual-address one-line ltm virtual-address 10.0.0.0 { address 10.0.0.0 arp disabled floating disabled icmp-echo disabled mask 255.255.0.0 route-advertisement selective traffic-group none unit 0 } ltm virtual-address 10.1.0.0 { address 10.1.0.0 arp disabled floating disabled icmp-echo disabled mask 255.255.0.0 route-advertisement selective traffic-group none unit 0 } ltm virtual-address 10.2.0.0 { address 10.2.0.0 arp disabled floating disabled icmp-echo disabled mask 255.255.0.0 route-advertisement selective traffic-group none unit 0 } (tmos)# list /net route tgw net route tgw { interface /Common/tgw-connect network 10.0.0.0/8 } Output from TMSH. Note route-advertisement is enabled on the virtual-addresses. We are using a static route to steer traffic to the GRE tunnel. You should also see any routes advertised as well. ECMP Considerations When you deploy multiple BIG-IP devices TGW can use ECMP to spray traffic across multiple devices (by enabling traffic group None or multiple standalone devices). Be aware that if you need to statefully inspect traffic you may want to enable SNAT to have the return traffic go to the same device or use traffic-group-1 to run in Active/Standby via Route Health Injection. Otherwise you will need to follow the guidance on setting up a forwarding virtual server to ignore the system connection table. Routing Connections One of the issues that a customer discovered when exploring this solution is that the BIG-IP will initially send health checks across the GRE tunnel using an IP from the 169.254.x.x address range, this follows the address selection criteria that a BIG-IP uses. One method of dealing with this is to assign an IP address in a range that you would like to advertise across the tunnel like 198.168.254.0/24. Creating a self-ip of 198.168.254.253 that you assign to the tunnel. To send traffic for a different range (i.e. 10.0.0.0/16) you can then create a static route on the BIG-IP that points to 198.168.254.1. Since the BIG-IP sees the address is on the tunnel it will correctly forward the traffic through the tunnel. Another question that arose was whether it was possible to have asymmetric traffic flows of utilizing both the GRE TGW Connect tunnel and the TGW VPC Connection of the VPC itself. I discovered that YES this is possible by following the guidance on enabling asymmetrically routed traffic. It hurts your brain a bit, but here's the results of a flow that is using both a Connect and VPC connection. You can do some crazy things, but with great power... Request traffic over VPC Connection Response traffic over TGW Connect (GRE) Other Options You could also achieve a similar result by using default VPC peering and making use of Cloud Failover Extension for updating the route table. The benefit of that approach is that you don't have to deal with GRE/BGP! It does limit you to a single device per-AZ vs. being able to get up to 4 devices running across a connection.Welcome to the F5 BIG-IP Migration Assistant - Now the F5 Journeys App
The older F5 BIG-IP Migration Assistant is deprecated and is replaced by F5 Journeys. Welcome to the F5 Journeys App - BIG-IP Upgrade and Migration Utility F5 Journeys App Readme @ Github What is it? The F5® Journeys BIG-IP upgrade and migration utility is a tool freely distributed by F5 to facilitate migrating BIG-IP configurations between different platforms. F5 Journeys is a downloadable assistant that coordinates the logistics required to migrate a BIG-IP configuration from one BIG-IP instance to another. Why do I need it? JOURNEYS is an application designed to assist F5 Customers with migrating a BIG-IP configuration to a new F5 device and enable new ways of migrating. Supported journeys: Full Config migration - migrating a BIG-IP configuration from any version starting at 11.5.0 to a higher one, including VELOS and rSeries systems. Application Service migration - migrating mission critical Applications and their dependencies to a new AS3 configuration and deploying it to a BIG-IP instance of choice. What does it do? It does a bunch of stuff: Loading UCS or UCS+AS3 source configurations Flagging source configuration feature parity gaps and fixing them with provided built-in solutions Load validation Deployment of the updated configuration to a destination device, including VELOS and rSeries VM tenants Post-migration diagnostics Generating detailed PDF reports at every stage of the journey Full config BIG-IP migrations are supported for software paths according to the following matrix: DEST X 11.x 12.x 13.x 14.x 15.x 16.x <11.5 X X X X^ X^ 12.x X X X X^ SRC 13.x X X X 14.x X X X 15.x X X 16.x How does it work? F5 Journeys App manages the logistics of a configuration migration. The F5 Journeys App either generates or accepts a UCS file from you, prompts you for a destination BIG-IP instance, and manages the migration. The destination BIG-IP instance has a tmsh command that performs the migration from a UCS to a running system. F5 Journeys uses this tmsh command to accomplish the migration using the platform-migrate option (see more details K82540512) . The F5 Journeys App prompts you to enter a source BIG-IP (or upload a UCS file), the master key password, and destination BIG-IP instance. Once the tool obtains this information, it allows you to migrate the source BIG-IP configuration to the destination BIG-IP instance either entirely or in a per-application depending what you choose. Where do I obtain it? F5 Journeys App Readme @ Github What can go wrong? Bug reporting Let us know if something went wrong.

F5 lists 82 product offerings in the AWS Marketplace as Amazon Machine Images (AMI). Each version of each product in each AWS Region has a different AMI. That’s around 22,000 images! Each AMI is identified by an AMI ID. You use the AMI ID to indicate which AMI you want to use when launching an F5 product. You can find AMI IDs using the AWS Web Console, but the AWS CLI is the best tool for the job. Searching for AMIs using the AWS CLI Here’s how you find the AMI IDs for version 17.5.1.2 of BIG-IP Virtual Edition in the us-east-1 AWS region: aws ec2 describe-images --owners aws-marketplace --filters 'Name=name,Values=F5 BIGIP-17.5.1.2*' --query "sort_by(Images,&Name)[:]. {Description: Description, Id:ImageId }" --region us-east-1 --output table ---------------------------------------------------------------------------------------------------- | DescribeImages | +------------------------------------------------------------------------+-------------------------+ | Description | Id | +------------------------------------------------------------------------+-------------------------+ | F5 BIGIP-17.5.1.2-0.0.5 BYOL-All Modules 1Boot Loc-250916013758 | ami-0948eabdf29ef2a8f | | F5 BIGIP-17.5.1.2-0.0.5 BYOL-All Modules 2Boot Loc-250916015535 | ami-0cb3aaa67967ad029 | | F5 BIGIP-17.5.1.2-0.0.5 BYOL-LTM 1Boot Loc-250916013616 | ami-05d70b82c9031ff39 | | F5 BIGIP-17.5.1.2-0.0.5 BYOL-LTM 2Boot Loc-250916014744 | ami-0b6021cc939308f3e | | F5 BIGIP-17.5.1.2-0.0.5 BYOL-encrypted-threat-protection-250916015535 | ami-01f4fde300d3763be | | F5 BIGIP-17.5.1.2-0.0.5 PAYG-AWF Plus 16vCPU-250916015534 | ami-015474056159387ac | | F5 BIGIP-17.5.1.2-0.0.5 PAYG-Adv WAF Plus 200Mbps-250916015522 | ami-06ce5b03dce2a059d | | F5 BIGIP-17.5.1.2-0.0.5 PAYG-Adv WAF Plus 25Mbps-250916015520 | ami-0826808708df97480 | | F5 BIGIP-17.5.1.2-0.0.5 PAYG-Adv WAF Plus 3Gbps-250916015523 | ami-08c63c8f7ca71cf37 | | F5 BIGIP-17.5.1.2-0.0.5 PAYG-Best Plus 10Gbps-250916015532 | ami-0e806ef17838760e4 | | F5 BIGIP-17.5.1.2-0.0.5 PAYG-Best Plus 1Gbps-250916015530 | ami-05e31c2a0ac9ec050 | | F5 BIGIP-17.5.1.2-0.0.5 PAYG-Best Plus 200Mbps-250916015528 | ami-02dc0995af98d0710 | | F5 BIGIP-17.5.1.2-0.0.5 PAYG-Best Plus 25Mbps-250916015527 | ami-08b8f2daefde800e9 | | F5 BIGIP-17.5.1.2-0.0.5 PAYG-Best Plus 5Gbps-250916015531 | ami-0d16154bb1102f3e9 | | F5 BIGIP-17.5.1.2-0.0.5 PAYG-Better 10Gbps-250916015512 | ami-05c9527fff191feba | | F5 BIGIP-17.5.1.2-0.0.5 PAYG-Better 1Gbps-250916015510 | ami-05ce2932601070d5c | | F5 BIGIP-17.5.1.2-0.0.5 PAYG-Better 200Mbps-250916015508 | ami-0f6044db3900ba46f | | F5 BIGIP-17.5.1.2-0.0.5 PAYG-Better 25Mbps-250916014542 | ami-0de57aba160170358 | | F5 BIGIP-17.5.1.2-0.0.5 PAYG-Better 5Gbps-250916015511 | ami-04271103ab2d1369d | | F5 BIGIP-17.5.1.2-0.0.5 PAYG-Good 10Gbps-250916014739 | ami-0d06d2a097d7bb47a | | F5 BIGIP-17.5.1.2-0.0.5 PAYG-Good 1Gbps-250916014737 | ami-01707e969ebcc6138 | | F5 BIGIP-17.5.1.2-0.0.5 PAYG-Good 200Mbps-250916014735 | ami-06f9a44562d94f992 | | F5 BIGIP-17.5.1.2-0.0.5 PAYG-Good 25Mbps-250916013626 | ami-0aa2bca574c66af13 | | F5 BIGIP-17.5.1.2-0.0.5 PAYG-Good 5Gbps-250916014738 | ami-01951e02c52deef85 | | F5 BIGIP-17.5.1.2-0.0.5 PAYG-PVE Adv WAF Plus 200Mbps-0916015525 | ami-03df50dfc04f19df5 | | F5 BIGIP-17.5.1.2-0.0.5 PAYG-PVE Adv WAF Plus 25Mbps-50916015524 | ami-0777c069eaae20ea1 | +------------------------------------------------------------------------+-------------------------+ This command shows all 17.5.1* releases of the "PayGo Good 1Gbps" flavor of BIG-IP in the us-west-1 region sorted by newest release first: aws ec2 describe-images --owners aws-marketplace --filters 'Name=name,Values=F5 BIGIP-17.5.1*PAYG-Good 1Gbps*' --query "reverse(sort_by(Images,&CreationDate))[:]. {Description: Name, Id:ImageId , date:CreationDate}" --region us-west-1 --output table ---------------------------------------------------------------------------------------------------------------------------------------------------- | DescribeImages | +--------------------------------------------------------------------------------------------+------------------------+----------------------------+ | Description | Id | date | +--------------------------------------------------------------------------------------------+------------------------+----------------------------+ | F5 BIGIP-17.5.1.2-0.0.5 PAYG-Good 1Gbps-250916014737-7fb2f9db-2a12-4915-9abb-045b6388cccd | ami-0de8ca1229be5f7fe | 2025-09-16T23:12:28.000Z | | F5 BIGIP-17.5.1-0.80.7 PAYG-Good 1Gbps-250811055424-7fb2f9db-2a12-4915-9abb-045b6388cccd | ami-09afcec6f36494382 | 2025-08-15T19:03:23.000Z | | F5 BIGIP-17.5.1-0.0.7 PAYG-Good 1Gbps-250618090310-7fb2f9db-2a12-4915-9abb-045b6388cccd | ami-03e389e112872fd53 | 2025-07-01T06:00:44.000Z | +--------------------------------------------------------------------------------------------+------------------------+----------------------------+ Notice that the same BIG-IP VE release has a different AMI ID in each AWS region. Attempting to launch a product in one region using an AMI ID from a different region will fail. This causes a problem when a shell script or automation tool is used to launch new EC2 instances and the AMI IDs have been hardcoded for one region and you attempt to use it in another. Wouldn’t it be nice to have a single AMI identifier that works in all AWS regions? Introducing AMI Aliases The Ami Alias is a similar ID to the AMI ID, but it’s easier to use in automation. An AMI alias has the form /aws/service/marketplace/prod-<identifier>/<version> , for example, "PayGo Good 1Gbps" /aws/service/marketplace/prod-s6e6miuci4yts/17.5.1.2-0.0.5 You can use this Ami Alias ID in any Region, and AWS automatically maps it to the correct Regional AMI ID.

GOOD (PAYG, 1Gbps)" instance version 17.5.1.2-0.0.5 by using the AWS CLI. aws ec2 run-instances --image-id resolve:ssm:/aws/service/marketplace/prod-s6e6miuci4yts/17.5.1.2-0.0.5 --instance-type m5.xlarge --key-name MyKeyPair The next example shows a CloudFormation template that accepts the AMI alias as an input parameter to create an instance. AWSTemplateFormatVersion: 2010-09-09 Parameters: AmiAlias: Description: AMI alias Type: 'String' Resources: MyEC2Instance: Type: AWS::EC2::Instance Properties: ImageId: !Sub "resolve:ssm:${AmiAlias}" InstanceType: "g4dn.xlarge" Tags: -Key: "Created from" Value: !Ref AmiAlias Using AMI Aliases for NGINX Plus NGINX Plus images in the AWS Marketplace are not version specific, so just use "latest" as the version to launch. For example, this will launch NGINX Plus Premium on Ubuntu 24.04: aws ec2 run-instances --image-id resolve:ssm:/aws/service/marketplace/prod-opg2qh33mi4pk/latest --instance-type c5.large --key-name MyKeyPair Finding AMI Aliases in AWS Marketplace AMI aliases are new to the AWS Marketplace, so not all products have them. To locate the alias for an AMI you use often, you need to resort to the AWS Marketplace web console. Here are the step-by-step instructions provided by Amazon: 1. Navigate to AWS Marketplace Go to AWS Marketplace Sign in to your AWS account 2. Find and Subscribe to the Product Search for or browse to find your desired product Click on the product listing Click "Continue to Subscribe" Accept the terms and subscribe to the product 3. Configure the Product After subscribing, click "Continue to Configuration" Select your desired: Delivery Method (if multiple options are available) Software Version Region 4. Locate the AMI Alias At the bottom of the configuration page, you'll see: AMI ID: ami-1234567890EXAMPLE AMI Alias: /aws/service/marketplace/prod-<identifier>/<version> New Tools for Your AMI Hunt In this article, we focused on using AMI Aliases to select the right F5 product to launch in AWS EC2. But, there’s one more takeaway. Scroll back up to the top of this page and take a closer look at the "aws ec2 describe-images" commands. These commands use JMESpath to filter, sort, and format the output. Find out more about filtering the output of AWS CLI commands here.NGINX Plus R35 for Federal Environments: FIPS-Compliant algorithms with ACME Certificates in AWS
NGINX Plus R35 offers a fantastic combination of built-in ACME support and also supports using FIPS-compliant cryptographic algorithms. This guide walks through configuring a setup of Nginx to use Let's Encrypt for automatic certificate generation and renewal with FIPS approved algorithms. I should clarify that if you do not want to use FIPS approved algorithms, it is very simple to change the cipher suite lines to meet your particular needs.Building an OpenSSL Certificate Authority - Creating Your Root Certificate
Creating Your Root Certificate Authority In our previous article, Introductions and Design Considerations for Eliptical Curves we covered the design requirements to create a two-tier ECC certificate authority based on NSA Suite B's PKI requirements. We can now begin creating our CA's root configuration. Creating the root CA requires us to generate a certificate and private key, since this is the first certificate we're creating, it will be self-signed. The root CA will not sign client and server certificates, it's job it only to create intermeidary certificates and act as the root of our chain of trust. This is standard practice across the public and private PKI configurations and so too should your lab environments. Create Your Directory Structure Create a directory to store your root CA pair and config files. # sudo bash # mkdir /root/ca Yep, I did that. This is for a test lab and permissions may not match real world requirements. I sudoed into bash and created everything under root; aka playing with fire. This affects ownership down the line if you chmod private key files and directories to user access only so determine for yourself what user/permission will be accessing files for certificate creation. I have a small team and trust them with root within a lab environment (snapshots allow me to be this trusting). Create your CA database to keep track of signed certificates # cd /root/ca # mkdir private certs crl # touch index.txt # echo 1000 > serial We begin by creating a working root directory with sub directories for the various files we'll be creating. This will allow you to apply your preferred security practices should you choose to do so. Since this is a test lab and I am operating as root, I won't be chmod'ing anything today. Create Your OpenSSL Config File OpenSSL uses configuration files to simplify/template the components of a certificate. Copy the GIST openssl_root.cnf file to /root/ca/openssl_root.cnf which is already prepared for this demo. For the root CA certificate creation, the [ CA ] section is required and will gather it's configuration from the [ CA_default ] section. [ ca ] # `man ca` default_ca = CA_default The [CA_default] section in the openssl_root.cnf file contains the variables OpenSSL will use for the root CA. If you're using alternate directory names from this demo, update the file accordingly. Note the long values for default days (10 years) as we don't care about renewing the root certificate anytime soon. [ CA_default ] # Directory and file locations. dir = /root/ca certs = $dir/certs crl_dir = $dir/crl new_certs_dir = $dir/certs database = $dir/index.txt serial = $dir/serial RANDFILE = $dir/private/.rand # The root key and root certificate. private_key = $dir/private/ca.cheese.key.pem certificate = $dir/certs/ca.cheese.crt.pem # For certificate revocation lists. crlnumber = $dir/crlnumber crl = $dir/crl/ca.cheese.crl.pem crl_extensions = crl_ext default_crl_days = 3650 # SHA-1 is deprecated, so use SHA-2 or SHA-3 instead. default_md = sha384 name_opt = ca_default cert_opt = ca_default default_days = 3650 preserve = no policy = policy_strict For the root CA, we define [policy_strict] which will later force the intermediary's certificate to match country, state/province, and organization name fields. [ policy_strict ] The root CA should only sign intermediate certificates that match. # See POLICY FORMAT section of `man ca`. countryName = match stateOrProvinceName = match organizationName = match organizationalUnitName = optional commonName = supplied emailAddress = optional The [ req ] section is used for OpenSSL certificate requests. Some of the values listed will not be used since we are manually specifying them during certificate creation. [ req ] # Options for the `req` tool (`man req`). default_bits = 4096 distinguished_name = req_distinguished_name string_mask = utf8only # SHA-1 is deprecated, please use SHA-2 or greater instead. default_md = sha384 # Extension to add when the -x509 option is used. x509_extensions = v3_ca I pre-populate the [ req_distinguished_name ] section with values I'll commonly used to save typing down the road. [ req_distinguished_name ] countryName = Country Name (2 letter code) stateOrProvinceName = State or Province Name localityName = Locality Name 0.organizationName = Organization Name organizationalUnitName = Organizational Unit Name commonName = Common Name emailAddress = Email Address # Optionally, specify some defaults. countryName_default = US stateOrProvinceName_default = WA localityName_default = Seattle 0.organizationName_default = Grilled Cheese Inc. organizationalUnitName_default = Grilled Cheese Root CA emailAddress_default = [email protected] The [ v3_ca ] section will further define the Suite B PKI requirements, namely basicConstraints and acceptable keyUsage values for a CA certificate. This section will be used for creating the root CA's certificate. [ v3_ca ] # Extensions for a typical CA (`man x509v3_config`). subjectKeyIdentifier = hash authorityKeyIdentifier = keyid:always,issuer basicConstraints = critical, CA:true keyUsage = critical, digitalSignature, cRLSign, keyCertSign Selecting the Suite B compliant elliptical curve We're creating a Suite B infrastructure so we'll need to pick an acceptable curve following P-256 or P-384. To do this, run the following OpenSSL command: openssl ecparam -list_curves This will give you a long list of options but which one to pick? Let's isolate the suites within the 256 & 384 prime fields; we can grep the results for easier curve identification. openssl ecparam -list_curves | grep '256\|384' And we get the following results (your results may vary depending on the version of OpenSSL running): # openssl ecparam -list_curves | grep '256\|384' secp256k1 : SECG curve over a 256 bit prime field secp384r1 : NIST/SECG curve over a 384 bit prime field prime256v1: X9.62/SECG curve over a 256 bit prime field brainpoolP256r1: RFC 5639 curve over a 256 bit prime field brainpoolP256t1: RFC 5639 curve over a 256 bit prime field brainpoolP384r1: RFC 5639 curve over a 384 bit prime field brainpoolP384t1: RFC 5639 curve over a 384 bit prime field I am going to use secp384r1 as my curve of choice. It's good to mention that RFC5480 notes secp256r1 (not listed) is referred to as prime256v1 for this output's purpose. Why not use something larger than 384? Thank Google. People absolutely were using secp521r1 then Google dropped support for it (read Chromium Bug 478225 for more). The theory is since NSA Suite B PKI did not explicitly call out anything besides 256 or 384, the Chromium team quietly decided it wasn't needed and dropped support for it. Yea... it kinda annoyed a few people. So to avoid future browser issues, we're sticking with what's defined in public standards. Create the Root CA's Private Key Using the names defined in the openssl_root.cnf's private_key value and our selected secp384r1 ECC curve we will create and encrypt the root certificates private key. # openssl ecparam -genkey -name secp384r1 | openssl ec -aes256 -out private/ca.cheese.key.pem read EC key writing EC key Enter PEM pass phrase: ****** Verifying - Enter PEM pass phrase: ****** Note:The ecparam function within OpenSSL does not encrypt the private key like genrsa/gendsa/gendh does. Instead we combined the private key creation (openssl ecparam) with a secondary encryption command (openssl ec) to encrypt private key before it is written to disk. Keep the password safe. Create the Root CA's Certificate Using the new private key, we can now generate our root's self-signed certificate. We do this because the root has no authority above it to request trust authority from; it is the absolute source of authority in our certificate chain. # openssl req -config openssl_root.cnf -new -x509 -sha384 -extensions v3_ca -key private/ca.cheese.key.pem -out certs/ca.cheese.crt.pem Enter pass phrase for private/ca.cheese.key.pem: ****** You are about to be asked to enter information that will be incorporated into your certificate request.
