Cluster update known issues¶
This section lists the cluster update known issues with workarounds for the Mirantis OpenStack for Kubernetes release 23.1.
[27797] Cluster ‘kubeconfig’ stops working during MKE minor version update¶
During update of a Container Cloud management cluster, if the MKE minor
version is updated from 3.4.x to 3.5.x, access to the cluster using the
existing kubeconfig
fails with the You must be logged in to the server
(Unauthorized) error due to OIDC settings being reconfigured.
As a workaround, during the Container Cloud cluster update, use the
admin
kubeconfig
instead of the existing one. Once the update
completes, you can use the existing cluster kubeconfig
again.
To obtain the admin
kubeconfig
:
kubectl --kubeconfig <pathToMgmtKubeconfig> get secret -n <affectedClusterNamespace> \
-o yaml <affectedClusterName>-kubeconfig | awk '/admin.conf/ {print $2}' | \
head -1 | base64 -d > clusterKubeconfig.yaml
