In the ever-evolving world of Kubernetes, Helm remains a crucial tool for managing packages and deployments. However, as projects grow and changes are made, it’s not uncommon to encounter the need to rollback changes for stability or error correction. Here’s a comprehensive guide on how to rollback changes in Helm effectively in 2025.
Helm has a built-in rollback functionality, which allows you to revert to a previous release with minimal hassle. This feature is potent for maintaining stability and ensuring that any changes that introduce unexpected issues are swiftly undone.
List the Releases: To begin a rollback, first identify the release history. Use the command:
1
|
helm list --namespace [namespace] |
This will display all releases along with their versions.
Inspect the Revision History: To view the current revision and its history, execute:
1
|
helm history [release_name] --namespace [namespace] |
This command lists all the revisions for a specific release, showing which version you may want to revert to.
Perform the Rollback: Once you have identified the correct revision number, perform the rollback using:
1
|
helm rollback [release_name] [revision] --namespace [namespace] |
This command reverts your release to the selected version.
Verify the Rollback: Always verify the deployment to ensure the rollback was successful. This can be done by checking the status:
1
|
helm status [release_name] --namespace [namespace] |
By following these steps, rolling back changes in Helm in 2025 should be a straightforward task, allowing you to maintain stability and control over your deployments. “`
