This plugin adds helm update-config command to Helm CLI. It allows to update config values of an existing release running in the cluster.
helm plugin install https://github.com/zhanggbj/helm-update-config
To change image tag of smiling-penguin release:
helm update-config smiling-penguin --set-value=image.tag=stable
The plugin will reuse all the values defined in previous releases. If you want to override those you can set --reset-values flag the same way you do for helm upgrade.
