Environment

Platform9 Managed Kubernetes - v5.6 and Higher
Managed Platform9 Edge Cloud - v5.6 and Higher.

Answer

This is a know issue, Platform9 has a jira filed AIR-1268 to track and provide a permanent solution for this issue.

Workaround

The workaround is to patch the networkplugins.plumber.k8s.pf9.io CRD for the K8s cluster associated with respective management plane to use the Whereabouts v0.4.10 image.

Javascript
    
# kubectl patch networkplugins networkplugins-devtestcluster -n <NAMESPACE> --patch '{"spec": {"plugins": {"whereabouts": {"whereaboutsImage": "docker.io/platform9/whereabouts:v0.4.10"}}}}' --type merge -o yaml
