Helm rollback to previous release

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.

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

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

helm rollback <RELEASE> 0

Using Helm

helm rollback release-name 0

Using kubectl

What does rollout/rollback in kubectl means? Rolling updates allow the following actions:

  1. Promote an application from one environment to another (via container image updates).
  2. Rollback to previous versions.
  3. Continuous Integration and Continuous Delivery of applications with zero downtime.

kubectl rollout undo deployment/deployment-name

or

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

Unlike the previous old answers above.

According to the latest documentation, you can rollback to the previous version by simply omitting the argument in helm rollback. Which means your command should like below to rollback to the previous version.

helm rollback <RELEASE_NAME>

Below are the steps you can rollback Using Helm:

  1. Check the name of a release and (version) number using $ helm ls
  2. The first argument of the rollback command is the name of a release, and the second is a revision (version) number.
$ helm rollback RELEASE [REVISION]
