What are the best practices for rolling back a Helm release in Kubernetes?

When rolling back a Helm release, it's important to follow these best practices: 1. Always keep track of your release history. 2. Test your rollback in a staging environment first. 3. Use the helm rollback command with the release name and revision number. 4. Monitor the application after the rollback to ensure stability.

How can I check the release history before rolling back?

You can check the release history by using the command helm history <release-name>. This will show you all the revisions of the release along with their statuses.

What should I do if the rollback fails?

If the rollback fails, you can try rolling back to a previous stable revision using the helm rollback <release-name> <revision> command. Additionally, check the logs for any errors and consider troubleshooting the underlying issues.

Are there any tools to help with Helm rollbacks?

Yes, tools like Helm Diff can help you see the differences between revisions before rolling back, and tools like Kubeval can validate your Helm charts.
