Helm Diff Upgrade Plugin

This is a Helm plugin showing a preview of what a helm upgrade would change. (See helm diff) If there are changes detected you are prompted to proceed with the helm upgrade command with the same parameters.

Installation

helm plugin install https://github.com/code-chris/helm-diff-upgrade

Usage

Usage:
  diff-upgrade [args]

All args are redirected to the helm diff and helm upgrade commands, so you cannot use flags right now, which are only supported by one of these. To force a upgrade when there are changes without prompt (e.g. in CI environment) set the environment variable HELM_FORCE_DIFF_UPGRADE to 1.

Example

Example:
  helm diff-upgrade -n monitoring grafana bitnami/grafana -f grafana.yaml

Would result in:
  helm diff upgrade -C 3 --detailed-exitcode -n monitoring grafana bitnami/grafana -f grafana.yaml
  helm upgrade -i -n monitoring grafana bitnami/grafana -f grafana.yaml

Note: The -C 3 and --detailed-exitcode are hardcoded. The helm diff plugin is no prerequisite, its binary is downloaded internally.

OS Support

This plugin supports Linux and MacOS environments.
