We have migrated all our managed cluster add-ons and our CI to Helm 3.
Compared to Helm 2, version 3 comes with quite a lot of improvements, of which most aparent is the removal of the
Tiller server component:
- Removal of Tiller
- Release Names are now scoped to the Namespace, meaning there’s no longer need to add release suffixes like
-testand so forth!
- More robust update strategy via 3-way Strategic Merge Patches
- Library chart support, a chart that is shared by other charts, but does not create any release artifacts of its own
- And many others! Check out the upstream Changes since Helm 2 page.
So, what’s next? Each customer Lead will make contact with you to help and follow-up migration of your own application releases to Helm 3.
We’ve updated our documentation so be sure to check these out already:
Once all application releases have been fully migrated, we will remove Tiller from our clusters.
