Helm rollback to previous release

Question

I am looking for a way to rollback a helm release to its previous release without specifying the target release version as a number.

Something like helm rollback <RELEASE> ~1 (like git reset HEAD~1) would be nice.

Answer 1

As it turns out, there is an undocumented option to rollback to the last successful release by defining the target release version as 0. like: helm rollback <RELEASE> 0

Answer 2

Using Helm

helm rollback release-name 0

Using kubectl

kubectl rollout undo deployment/deployment-name

or

kubectl rollout undo deployment/deployment-name --to-revision=0

Answer 3

If you just want to rollback to the previous release, you can do

helm rollback <RELEASE> 0
