Deployment: Create DataVolumes: Import the XC CE image into the cluster using the Containerized Data Importer (CDI). Deploy VirtualMachine Resources: Apply manifests to deploy XC CE instances in OpenShift. Network Configuration Setting up the network involves creating Open vSwitch (OVS) bridges and defining NetworkAttachmentDefinitions (NADs) to enable multiple network interfaces for the virtual machines. Open vSwitch (OVS) Bridges Create a NodeNetworkConfigurationPolicy to define OVS bridges on all worker nodes: apiVersion: nmstate.io/v1 kind: NodeNetworkConfigurationPolicy metadata: name: ovs-vms spec: nodeSelector: node-role.kubernetes.io/worker: '' desiredState: interfaces: - name: ovs-vms type: ovs-bridge state: up bridge: allow-extra-patch-ports: true options: stp: true port: - name: eno1 ovn: bridge-mappings: - localnet: ce2-slo bridge: ovs-vms state: present Replace eno1 with the appropriate physical network interface on your nodes. This policy sets up an OVS bridge named ovs-vms connected to the physical interface. NetworkAttachmentDefinitions (NADs) Define NADs using Multus CNI to attach networks to the virtual machines. External Network (ce2-slo): External Network (ce2-slo): Connects VMs to the physical network with a specific VLAN ID. This setup allows the VMs to communicate with external systems, services, or networks, which is essential for applications that require access to resources outside the cluster or need to expose services to external users. apiVersion: k8s.cni.cncf.io/v1 kind: NetworkAttachmentDefinition metadata: name: ce2-slo namespace: f5-ce spec: config: | { "cniVersion": "0.4.0", "name": "ce2-slo", "type": "ovn-k8s-cni-overlay", "topology": "localnet", "netAttachDefName": "f5-ce/ce2-slo", "mtu": 1500, "vlanID": 3052, "ipam": {} } Internal Network (ce2-sli): Internal Network (ce2-sli): Provides an isolated Layer 2 network for internal communication. By setting the topology to "layer2", this network operates as an internal overlay network that is not directly connected to the physical network infrastructure. The mtu is set to 1400 bytes to accommodate any overhead introduced by encapsulation protocols used in the internal network overlay. apiVersion: k8s.cni.cncf.io/v1 kind: NetworkAttachmentDefinition metadata: name: ce2-sli namespace: f5-ce spec: config: | { "cniVersion": "0.4.0", "name": "ce2-sli", "type": "ovn-k8s-cni-overlay", "topology": "layer2", "netAttachDefName": "f5-ce/ce2-sli", "mtu": 1400, "ipam": {} } VirtualMachine Configuration Configuring the virtual machine involves preparing the image, creating cloud-init user data, and defining the VirtualMachine resource. Image Preparation Obtain XC CE Image: Download the qcow2 image from the F5 Distributed Cloud Console. Generate Node Token: Acquire a one-time node token for node registration. Cloud-Init User Data Create a user-data configuration containing the node token and network settings: #cloud-config write_files: - path: /etc/vpm/user_data content: | token: <your-node-token> slo_ip: <IP>/<prefix> slo_gateway: <Gateway IP> slo_dns: <DNS IP> owner: root permissions: '0644' Replace placeholders with actual network configurations. This file automates the VM's initial setup and registration. VirtualMachine Resource Definition Define the VirtualMachine resource, specifying CPU, memory, disks, network interfaces, and cloud-init configurations. Resources: Allocate sufficient CPU and memory. Disks: Reference the DataVolume containing the XC CE image. Interfaces: Attach NADs for network connectivity. Cloud-Init: Embed the user data for automatic configuration.

Hi all, We have installed CE site in our network and this site has established IPSEC tunnels with RE nodes. The on-prem DC site has workloads (e.g actual web application servers that are serving the client requests). I have citrix netscaler background and the Citrix Netscalers ADCs are configured with VIPs which are the frontend for the client requests coming from outside (internet), when the request land on VIPs, it goes through both source NAT and destination NAT, its source address is changed to private address according to the service where the actual application servers are configured and then sent to the actual application server after changing the destination to IP address of the server. In XC, the request will land to the cloud first because the public IP, which is assigned to us will lead the request to RE. I have few questions regarding the events that will happen from here after Will there going to be any SNAT on the request or will it send it as it is to the site? And if there is SNAT then what IP address will it be ? and will it be done by the RE or on-prem CE There has to be destination NAT. Will this destination NAT is going to be performed by the XC cloud or the request will be sent to the site and site will do the destination NAT ? When the request will land the CE it will be landed in VN local outside so this means that we have to configure the network connector between the VN Local outside and the VN in which the actual workloads are configured, what type of that VN would be ? When the request will be responded by the application server in local on-prem the site the request has to go out to the XC cloud first, it will be routed via IPSEC tunnel so this means that we have to install the network connector between the Virtual network where the workloads are present and site local outside, do we have to install the default route in application VN ? Is there any document, post or article that actually help me to understand the procedure (frankly I read a lot of F5 documents but couldn’t able to find the answers200Views0likes10CommentsSeamless Application Migration to OpenShift Virtualization with F5 Distributed Cloud
