I am trying to install static/whereabouts (with multus) IPAM CNI plugin on GKE on Prem environment to create an additional interface and communicate with pods across the nodes in the same cluster.

Multus plugin is working well, but I am not seeing the bin file for static/whereabouts IPAM cni plugin on host directory (/opt/cni/bin) even after pointing the location in the daemonSet file.

I am wondering whether static/whereabouts IPAM cni plugins are supported but GKE on Prem.

Following is the changes I made in the whereabouts daemonSet file.

  namespace: kube-system

I was able to install whereabouts IPAM cni plugin. Does not need to point to the cni bin directory (/opt/cni/bin) in daemonSet file.

However, I could not install static IPAM cni plugin yet. Dont know how to install from git repo.

Any help would appreciate.

Thanks.
