Workload cluster 1.27 to 1.28

This is a known issue as per the error message of which advises the solution in it.

hint: Add annotation packaging.carvel.dev/downgradable: "" to PackageInstall to proceed with downgrade

As per guided here after upgrading a workload cluster from 1.27 to 1.28 the antrea package install fails to reconcile.

This error occurs because kapp-controller interprets the previously installed version (1.15.1+vmware.1-tkg.3-vmware) as higher than the desired version (1.15.1+vmware.1-tkg.4). By default, the controller does not allow downgrades unless explicitly permitted.

Resolution

The solution is as per hint in error received which is to add the below annotation to the package install of antrea.

packaging.carvel.dev/downgradable: ""

To do this you need to edit the antrea package install using below command:

kubectl edit pkgi antrea -n tkg-system

After adding the annotation advised Save the edit using either of below:

:wq!

or

:x!

-- either of the above will save the edit of the antrea package install.
