README.md

! Ensure your Kube context points to the correct cluster !

Trigger the cluster upgrade

./upgrade_121.sh

Upgrade CFN stacks for the control plane and all worker groups

Reboot controller(s) one by one

Patch current deployments, blocking ArgoCD otherwise

./kubezero_121.sh

Migrate ArgoCD config for the cluster

./migrate_argo.sh "cluster/env/kubezero/application.yaml"

Adjust as needed, eg. ensure eck-operator is enabled if needed. git add / commit / push

Watch ArgoCD do its work.

Replace worker nodes

Known issues

  • pods seem stuck, eg. fluent-bit on workers shows NotReady after control nodes have been ugpraded
    -> restart kube-proxy on the affected workers
