Issue/Introduction

Upon Upgrading TKG or TKGS Guest cluster to K8s version 1.22.x you would notice some of the packages like Contour, Cert-manager, and Harbor goes into Reconciliation Failed state.

You would see the below error when you run kubectl get app or tanzu packages installed list commands

ubuntu@jumpbox:~$ tanzu package installed list

Resolution

From K8s 1.22 beta has been removed from apiversion for Rolebinding https://kubernetes.io/blog/2021/07/14/upcoming-changes-in-kubernetes-1-22/ . In order to fix the issue, we need to upgrade the corresponding package.

Lets take an example of Harbor package and the procedure to upgrade the same.

Note: Upgrading Harbor packages rotates the CA certificate if the certificate wss self signed and generated by cert-manager so if you are using this Harbor for Image push/pull for other clusters you would have to update this certificate to those workload clusters.

ubuntu@jumpbox:~$ tanzu package repository get tanzu-standard -n tanzu-package-repo-global
- Retrieving repository tanzu-standard... 

NAME:          tanzu-standard
VERSION:       1090396
REPOSITORY:    projects.registry.vmware.com/tkg/packages/standard/repo
TAG:           v1.4.0
STATUS:        Reconcile succeeded
REASON:
ubuntu@jumpbox:~$ tanzu package repository update tanzu-standard --url projects.registry.vmware.com/tkg/packages/standard/repo -n tanzu-package-repo-global

ubuntu@jumpbox:~$ tanzu package repository list -A
- Retrieving repositories... 
  NAME            REPOSITORY                                               TAG                     STATUS               DETAILS  NAMESPACE

  • Once the tanzu-standard package repository is updated, we need to update the Harbor package. Lets get the list of available package version for Harbor
ubuntu@jumpbox:~$ tanzu package available list harbor.tanzu.vmware.com
- Retrieving package versions for harbor.tanzu.vmware.com...

  NAME                     VERSION               RELEASED-AT
  harbor.tanzu.vmware.com  2.2.3+vmware.1-tkg.1  2021-07-07 18:00:00 +0000 UTC
  harbor.tanzu.vmware.com  2.2.3+vmware.1-tkg.2  2021-07-07 18:00:00 +0000 UTC
  harbor.tanzu.vmware.com  2.3.3+vmware.1-tkg.1  2021-09-28 06:05:00 +0000 UTC
ubuntu@jumpbox:~$

As you can see the latest version of the Harbor package is 2.3.3 we can update to that version

ubuntu@jumpbox:~$ tanzu package installed update harbor -v 2.3.3+vmware.1-tkg.1 -f harbor-data-values.yaml -n default

 Updating installed package 'harbor'
- Getting package install for 'harbor' 
 Getting package install for 'harbor'
 Getting package metadata for 'harbor.tanzu.vmware.com'
 Updating secret 'harbor-default-values'
 Updating package install for 'harbor'
 Waiting for 'PackageInstall' reconciliation for 'harbor'

After the package is upgraded you would see Reconciliation success for the apps 

kubectl get apps
NAME     DESCRIPTION           SINCE-DEPLOY   AGE
harbor   Reconcile succeeded   2m5s           2d9h
