What do you need to know about helm commands?
Helm commands work with several Helm-related concepts. Understanding them makes the syntax easier to follow. The most important Helm concept is a chart. A chart is a set of Kubernetes yaml manifests packaged together for easy manipulation.
Is the helm chart the same as the application?
As mentioned before a Helm chart version is completely different than the application version it contains. This means that you can track versions on the Helm chart itself separately from the applications it defines. This is the most basic versioning approach and it is the suggested one if you are starting out with Helm.
Do you have to enforce version changes in helm?
Helm does not enforce chart version changes. You can deploy a different chart with the same version as the previous one. So, if this is something that you want to do, you need to make sure that all teams are on the same page for versioning practices.

How to roll back to a previous version of Helm?
This command rolls back a release to a previous revision. The first argument of the rollback command is the name of a release, and the second is a revision (version) number. To see revision numbers, run ‘helm history RELEASE’. If you’d like to rollback to the previous release use ‘helm rollback [RELEASE] 0’.
