Verify the management cluster status before MOSK update¶

Before you start updating your MOSK clusters, Mirantis recommends verifying that the associated management cluster is upgraded successfully.

To verify that the management cluster is upgraded successfully:

Using kubeconfig of the management cluster, verify the Cluster release version of the management cluster machines:

for i in $(kubectl get lcmmachines | awk '{print $1}' | sed '1d'); do echo $i; kubectl get lcmmachines $i -o yaml | grep release | tail -1; done

Example of system response:

master-0
  release: 14.0.0+3.6.5
master-1
  release: 14.0.0+3.6.5
master-2
  release: 14.0.0+3.6.5

Obtain the name of the latest available MOSK management release object:

kubectl get kaasrelease

Example of system response:

NAME          AGE
kaas-2-15-0   63m
kaas-2-14-0   40d

Using the name of the latest MOSK management release object, obtain the latest available Cluster release version:

kubectl get -o yaml clusterrelease $(kubectl get kaasrelease kaas-2-15-0 -o yaml | egrep "^ +clusterRelease:" | cut -d: -f2 | tr -d ' ') | egrep "^  version:"

Example of system response:

version: 14.0.0+3.6.4

Compare the output obtained in the previous step with the output from the first step. The Cluster releases must match. If this is not the case, contact Mirantis support for further details.
Proceed to Step 2. Initiate MOSK cluster update.
