F5OS using Ansible Linux Shell with remote users as iCall replacement(works with banner as well).
(AI Made picture so don't take it as 100% truth) In F5OS 1.8.0 and up remote users can automatically enter the Linux Shell if they have the correct remote group parameters and if this is system level enabled as shown in https://clouddocs.f5.com/training/community/rseries-training/html/rseries_security.html#superuser-role The superuser role if enabled can still trigger F5OS commands with "f5sh" that is similar to "tmsh" in TMOS and described in https://my.f5.com/manage/s/article/K000148922 . Code version: The code was tested on F5OS 1.8.4 rSeries 5900 Ansible Example without banner: --- - name: Restart docker container hosts: f5os gather_facts: no vars: container_name: tcpdumpd_manager tasks: - name: Restart the specified docker container ansible.builtin.shell: | docker restart {{ container_name }} become: false args: executable: /bin/bash Cronjobs also can be edited through shell Ansible playbook for scheduling transferred scripts. - name: Add cron job ansible.builtin.shell: | (crontab -l 2>/dev/null | grep -Fv '/opt/check_service.sh'; \ echo '*/5 * * * * /opt/check_service.sh') | crontab - become: false args: executable: /bin/bash Great Ansible F5OS automation article with cool examples that even has file transfer for transferring script file to the F5OS: Five Ways to Automate F5OS with Ansible: A Practical Guide | DevCentral Ansible Example with banner: The F5OS ssh banner is inserted between the username and password and that breaks the shell module as I did found out. I suspect that Ansible uses the PEXPECT Python package that spans SSH session and it is similar to TCL EXPECT and most people dealing with iRules will find this interesting. You need to add sudo in-front of each command. - name: Restart container hosts: localhost gather_facts: false tasks: - name: Run docker command ansible.builtin.expect: command: >- ssh -tt -o StrictHostKeyChecking=no -o ConnectTimeout=10 -o ServerAliveInterval=5 -o ServerAliveCountMax=2 {{ ansible_user }}@{{ ansible_host }} responses: '(?i)password:': {{ ansible_pass }} '(?m)\$\s*$': "sudo docker restart {{ container_name }}\nexit\n" timeout: 20 echo: true delegate_to: localhost register: out Also SCP file transfer can be done through the EXPEC module. From Linux bash you can use f5sh to trigger F5OS commands. Examples are f5sh "show interface" and to chain commands f5sh "config; vlan 500; commit; exit" . If you just write f5sh, you will enter the F5os from the Linux. This is like tmsh for TMOS. Summary! This is great feature. TMOS also has cronjobs but after upgrade the cronjob is lost but not on F5OS, this is why icall scripts still are better for TMOS Tenants. iCall has the option to be triggered by logs and that in F5OS will be harder as it will need a bash script that is sitting as a background process as to monitor the logs and a cronjob can check if the script is still running as a device reboot will cause the script to stop running. The script can be transferred and started the way I have shown with RESTCONF REST-API with Ansible/AWX as the best option.F5OS restarting container services through REST API
(The Image is made with ChatGPT AI just to highlight the F5OS kubernetes cluster, for exact list of the kubernetes pods see https://my.f5.com/manage/s/article/K000134978) Most of the F5OS services are in docker containers as F5OS is made of kubernetes cluster. If there is a memory or CPU leakage or another issue that needs a container to be restarted then this feature will be helpful. With F5OS 1.8.4 the option to restart those services is available and here is a short demonstration. Code version: The code was tested on F5OS 1.8.4 rSeries 5900 CURL example: (:8888/restconf can be used or /api as I prefer the send one 🙂 ) curl -k -X POST -H'Content-Type: application/yang-data+json' -u <USERNAME>:<PASSWORD> "https://<MANAGEMENT-IP>:8888/restconf/data/openconfig-system:system/f5-system-diagnostics-qkview:diagnostics/f5-system-diagnostics-docker:os-utils/f5-system-diagnostics-docker:docker/f5-system-diagnostics-docker:restart" -d '{ "node" : "platform" , "service" : "snmpd" }' POSTMAN example: Ansible Example: Automating the F5OS token authentication as to not use basic authentication as it is better than sending username and password each time https://my.f5.com/manage/s/article/K000148418 - name: Resart Service ansible.builtin.uri: url: "https://10.10.10.12/api/data/openconfig-system:system/f5-system-diagnostics-qkview:diagnostics/f5-system-diagnostics-docker:os-utils/f5-system-diagnostics-docker:docker/f5-system-diagnostics-docker:restart" method: POST headers: Content-Type: application/yang-data+json X-Auth-Token: "{{ token }}" validate_certs: false status_code: - 200 body_format: json body: node: platform service: snmpd register: primary_key Great Ansible F5OS automation article with cool examples: Five Ways to Automate F5OS with Ansible: A Practical Guide | DevCentral F5OS API reference: https://clouddocs.f5.com/api/rseries-api/F5OS-A-1.8.4-api.html?section=f5-system-diagnostics-docker#operation/data_openconfig_system_system_f5_system_diagnostics_qkview_diagnostics_f5_system_diagnostics_docker_os_utils_f5_system_diagnostics_docker_docker_f5_system_diagnostics_docker_restart_post Github Repo Link: https://github.com/Nikoolayy1/F5OS-API-Ansible/blob/main/README.md Summary! This automation can be used for triggering process/service restart through the API. For example the logs a metrics can be send to a SIEM/SOAR server that then through Automation can trigger the restart. For more complex tasks needing the Linux access the new superuser role could be used https://clouddocs.f5.com/training/community/rseries-training/html/rseries_security.html#superuser-role and Automatons like Ansible playbooks that use the native shell module. There could be 2 ansible playbboks as one uploading a script and other executing or scheduling it through cronjob edition.Modernizing F5 BIG-IP Synchronized HA Pairs with Ansible Validated Content
I wanted to provide an update to a previous article I released a few months ago where we developed Ansible Automation Platform code to help with migrating Standalone Legacy platforms (non-iSeries, iSeries and Viprion Instances) to our Modern Architectures (rSeries and Velos) using F5OS Tenant instances. I am happy to announce that the code for Synchronized HA pairs has been completed, and we have uploaded it to Ansible Automation Hub as Validated Content. What is Ansible Automation Hub Validated Content? Ansible validated content collections contain pre-built YAML content (such as playbooks or roles) to address the most common automation use cases. You can use Ansible validated content out-of-the-box or as a learning opportunity to develop your skills. It's a trusted starting point to bootstrap your automation: use it, customize it, and learn from it. Due to the focus on customization and the intent for this content to be modified, it is not subject to the same support requirements as our certified collections. To this end, any issues with this content should be filed directly at the source repository for that collection. Why Synchronized HA Pairs? This is a very common use case for a lot of our customers who want resiliency and redundancy, especially for their applications and services. The biggest issue with migrating an HA Pair is that because of the way they are set up, things like Management IP Addresses and Master Keys are essential to the transition process. Even mismatched versions during upgrades cannot synchronize during the process of upgrading to major/minor releases. What does the updated Validated Code do? Standalone Migrations – Where you can change the Management IP, due to the nature of being a standalone device, an outage will occur during the transition period. o There are 2 options for Playbooks Single Playbook for the full migration 2 Parts where Part 1 – Does backups and does a big start stop of the unit Part 2 – Migrates the standalone device HA Pairs – Combined – This code is designed for a customer who just needs to transition both HA Units but isn’t concerned about an outage window. It will migrate both units at the same time to F5OS Tenants. The Playbooks for this Code are broken apart in specific areas Part 1 – Backup the Information Part 2 – Ensure Both Units are offline and Migrate both units at the same time. HA Pairs – Sequential – This code is designed for customers who need to migrate one unit at a time and maintain availability of their applications. It will migrate the Standby Unit first as part of the code When ready to transition the active unit, it will place it in Standby and make the Transitioned Standby unit the Active Node transferring services to it Then the previously Active Unit (now standby) will be migrated There are playbooks to the Code to break apart specific areas of the transition Part 1 – Backup the Information Part 2 – Ensure the Standby Devices are offline (via Management IP) and Migrate the Standby Unit Part 3 – Transition the Standby to become the Active Unit and Begin Transitioning the New Standby Unit (Previously Active Unit) similarly to Part 2 This code has been tested and validated against many different platforms, and there are plans to continue testing for other use cases. The Transition can be Like-for-Like versioning (i.e. 16.1.x to 16.1.x) within the same family tree or can be an upgrade at the same time (i.e. 15.1.10 à 17.5.1.3 or even 21.0.0) These are Ansible Playbooks with supporting roles tailored for Red Hat Ansible Automation Platform. It’s built to perform a lift-and-shift migration of a F5 BIG-IP configuration from one device to another—with optional OS upgrades included. What is the future of the code? I plan on adding some Validation code to separate roles/playbooks so customers could have points of references for testing, i.e. (ping tests and pool tests) before and after the transition, QKView Backups, and other information provided on the state of the unit prior to transition to ensure when migrated it can be validated that everything is the way it was. Notes about the Code The code is not designed to handle Non-VLANed infrastructure (F5OS is designed to be multi-tenant and setup with VLANs to deal with Multi-Tenancy) If your BIG-IPs use Untagged networks, they will need to be migrated to VLANed prior to using this code. Has not been validated/tested with FIPS-based environments Has not been validated/tested F5 DNS environments – Coming Soon HA Pairs must retain the Management IP address from source to destination; the code will ensure that the source device is powered off prior to transitioning it. Cool Additions Override variables are allowed as extra_vars to create flexibility in your deployment override_cpu - This allows you to set the CPUs of the Tenant OS. If the memory override isn’t set, it will be set to the same formula that the F5OS Gui would calculate. DEFAULT is set to 4 CPU override_disk_size - This allows you to set the Disk Space of the Tenant OS. DEFAULT is set to 120GB override_memory - This allows you to set the Memory of the Tenant OS. Be warned if over-provisioned, the Tenant may not start. DEFAULT is calculated by the CPU counts formula used in the GUI. tenant_nodes - This allows you to set the slot for the Tenant OS if there are multiple slots associated with your F5OS Partition. DEFAULT is an array object and it is set to [1] cryptos - This allows you to set the Crypto on the Tenant OS to either enabled or disabled. DEFAULT is set to enabled Variables for deployments – the code is designed to utilize specific hostnames and group names to execute the code. These variables allow connectivity to BIGIP and F5OS Tenants. When creating these hosts, you will need to provide When creating hosts in AAP, you will need to provide the following information ansible_host: - This is the IP Address of the device of the host ansible_user: - This is the username to login to the device ansible_password: - this is the password to login to the device; if using a credential in AAP, you would associate that variables information here as a reference. i.e. Standalone deployments host_vars f5_destination_partition – This is the F5OS Partition information f5_destination_tenant – This is the F5OS Tenant information f5_source – This is the source device HA Pair Deployments group_vars ha_pair_destination_chassis – contains a group of 2 hosts for the destination tenants to be deployed to (can be 2 hosts with the same information or different) ha_pair_source – contains a group of 2 hosts for the source BIG-IP Devices in a synchronized HA Pair. ha_pair_source_dynamic - this group is created automatically throughout the code to program the new Tenant OSes after deployment (DOES NOT NEED TO BE CREATED) Demos/Information We have uploaded a new demo video below, you’ll see an migration of a synchronized HA Pair of BIG-IPs running as Viprion Tenants on F5 B2250 Blades running 15.1.10 transitioning to a pair of rSeries R5800s Tenant OSs running 17.5.1.x — demonstrating a smooth modernization process.

Let’s make F5 platform modernization as seamless and automated as possible!Modernizing F5 Platforms with Ansible
I’ve been meaning to publish this article for some time now. Over the past few months, I’ve been building Ansible automation that I believe will help customers modernize their F5 infrastructure. This especially true for those looking to migrate from legacy BIG-IP hardware to next-generation platforms like VELOS and rSeries. As I explored tools like F5 Journeys and traditional CLI-based migration methods, I noticed a significant amount of manual pre-work was still required. This includes: Ensuring the Master Key used to encrypt the UCS archive is preserved and securely handled Storing UCS, Master Key and information assets in a backup host Pre-configuring all VLANs and properly tagging them on the VELOS partition before deploying a Tenant OS To streamline this, I created an Ansible Playbook with supporting roles tailored for Red Hat Ansible Automation Platform. It’s built to perform a lift-and-shift migration of a F5 BIG-IP configuration from one device to another—with optional OS upgrades included. In the demo video below, you’ll see an automated migration of a F5 i10800 running 15.1.10 to a VELOS BX110 Tenant OS running 17.5.0—demonstrating a smooth, hands-free modernization process. Currently Working Velos Velos Controller/Partition running (F5OS-C 1.8.1) - which allows Tenant Management IP to be in a different VLAN Migrates a standalone F5 BIG-IP i10800 to a VELOS BX110 Tenant OS VLAN'ed Source tenant required (Doesn’t support non-vlan tenants) rSeries Shares MGMT IP with the same subnet as the Chassis Partition.

Ansible Module bigip_device_info: what where they thinking
I was fiddeling around with ansible and wanted to build a playbook that triggers an HA-Sync, but only when there are pending changes (we don't use auto sync) and always sync from the active device to the group. Sounded like a straight forward job and should be easy using the following F5 Ansible modules: bigip_device_info (for failover_state, device_groups name and sync_status) bigip_configsync_action (for triggering the sync) But oh boy was I wrong. After debugging the JSON that was gathered by bigip_device_info I was pretty baffled, to be honest. Why does every singel maschine return the info of every maschine of the HA cluster and also arrange alphabetically by hostname? Imagine you have a cluster consisting of two applinaces named "applianceA" and applianceB" and you query both devices for failover_state, you get the following: Querying maschine "applianceA" for failover state: access device_info.devices[0].failover_state = failover state of "applianceA" access device_info.devices[1].failover_state = failover state of "applianceB" Querying maschine "applianceB" for failover state: access device_info.devices[0].failover_state = failover state of "applianceA" access device_info.devices[1].failover_state = failover state of "applianceB" This is in my opinion very pooly designed. I am expecting to get data from the particular device I am querying in the same excact location on every device. In this example one would have to first iterate over every item in the returend array, check if this is actually the data of the querried device and not it's HA partner. I don't think this is how ansible was supposed to work. Or maybe I'm just stupid and don't know how it's done correctly?Mastering Imperative and Declarative Automation with F5 BIG-IP – AppWorld 2025
At AppWorld 2025, Anton Varkalevich and I will be hosting a hands-on lab, "Mastering Imperative and Declarative Automation with F5 BIG-IP." I'm Matt Mabis, a Senior Solutions Architect in the Business Development/Technical Alliances department at F5. I specialize in solution integrations with our partnerships with Red Hat (Ansible and OpenShift), VMware, and Omnissa Horizon. Anton Varkalevich is a Solutions Engineer III for Financial Services at F5, specializing in ensuring financial customers have the right solutions to meet their unique needs. Automation plays a critical role in financial institutions, enabling them to serve their customers quickly and effectively. This lab is the result of years of experience working with customers to streamline application deployments on F5 BIG-IP. We’ll use Ansible Automation Platform to demonstrate both imperative and declarative automation approaches. Participants will first deploy common use cases—such as HTTPS and SSL-delivered applications—using imperative automation with individual Ansible modules. Then, we’ll achieve the same outcomes using declarative automation, offering a side-by-side comparison to help attendees choose the best approach for their needs. By the end of this lab, you’ll have a solid understanding of both automation styles and how to apply them effectively in your environment. Join us at AppWorld 2025—we look forward to sharing our knowledge with you!Ansible modules for F5OS
Hello everyone, Any ansible modules available to configure F5OS hypervisor?, i am looking to automate the baseline configuration when we have a new F5OS based box, when i say baseline configuration it includes setting the hostnames, login banner, dns server, ntp, snmp, creating new tenants etc... are they any plans from F5 to release ansible modules for F5OS like what F5 team releases modules for BIG-IP??. if there are no plans what would be the general recommendation to go with either ansible shell module (or) ansible expect module to configure the F5OS box?? thank you, kumar
BigIP UCS Backup script; looking for some guidance on design
Greetings, I've began to work on a bash script, intended to be ran locally on each F5 appliance via a cron task. The criteria for this script has been, Saves the UCS /w encryption using {Hostname}-YYYY-MM-DD.ucs naming format. Uploads the generated UCS file to a SFTP server SFTP native commands are a MUST, SCP will not work due to it's reliance on command shell/login. Rollover after X # of saved files in order to prevent storage exhaustion on the target SFTP Server I strongly doubt any form of deduplication will work with a encrypted UCS Sends an email notification if the backup failed I've so far written a script that addresses the first 3 criteria and have been waiting for those to go through their paces in testing before adding in notification logic. The commands and logic being used have gotten more complex, the further I've gotten into the script's development. This has lead to some concerns about whether this is the best approach given the nature of the F5 BigIP systems being a vendor appliance and worry that there's a large possibility commands may stop working correctly after a major x. version update, requiring an overhaul of a fairly complex script. I'm almost wondering if setting up an AWX/Tower host in our environment and then using the f5networks Ansible Module for the majority of the heavy lifting followed by some basic logic for file rotation, would be a better long term approach. Ansible would also be a bit more flexible in that I wouldn't have to hardcore values that diverge between individual hosts into the script itself. It's however not clear if the F5networks ansible module supports SFTP as I only see SCP referenced. https://my.f5.com/manage/s/article/K35454259 Advice and insight is much appreciated! #!/bin/bash # F5 backup script based on https://my.f5.com/manage/s/article/K000138297 # User-configurable Variables UCS_DIR="/var/ucs" REMOTE_USER="svc_f5backup" REMOTE_HOST="myhost.contoso.local" REMOTE_DIR="/data/f5/dev" SSH_KEY="/shared/scripts/f5-backup/mykeys/f5user" ENCRYPTION_PASSPHRASE='' # Blank out the value to not encrypt the UCS backup.
