Multi-cluster Kubernetes using F5 BIG-IP

[@muhamadyusuphamdani9909]

If CNI use Flannel, its work? Or Change to calico?

[@MarkDittmer]

Flannel is VXLAN based which requires tunnels between BIGIP and K8S. HA doesn’t work!! Recommend using Calico with static routing mode.. I have a video coming on how to set this up. It’s super simple. Calico using static routes on BIGIP was added in 2.17. Let me know how I can help

CIS is perfect for what you want todo. Deploy CIS and point to service in the cluster. You could use node port and node port labels to only service the 3 workers. Or clusterIP will work good to

I believe you can use static routes with flannel. Email me at [e-mail] and I will share the setup docs
