After updating from ArgoCD 1.4 to 2.0

[dlebee]

Hello, I updated my argoCD from 1.4 to 2.0.

Everything seems to work fine, after needing to reconfigure some stuff.

My issue is when a PVC was created with Tiller in the past, and ArgoCD wants to create using Helm now.

It causes a sync error because some of the values are immutable.

Is there any solution to fix this manner? except having to re-deploy a fresh new MariaDB & Redis?

Here are some screenshots to show the issue:

Thank you,
David.

Hey, what you see is rooted in the fact that Argo CD v2.0 now uses Helm 3 as the default tool to render Helm charts, and this will generate values for the heritage label. This is covered here. You can explicitly set back to Helm v2, which will use the same value in the heritage label as before.

Alternatively, you might also have success with new feature that uses replace instead of apply: https://argo-cd.readthedocs.io/en/stable/user-guide/sync-options/#replace-resource-instead-of-applying-changes
