The Helm Diff Plugin

* Shows a diff explaining what a helm upgrade would change:
    This fetches the currently deployed version of a release
  and compares it to a local chart plus values. This can be 
  used visualize what changes a helm upgrade will perform.

* Shows a diff explaining what had changed between two revisions:
    This fetches previously deployed versions of a release
  and compares them. This can be used visualize what changes 
  were made during revision change.

* Shows a diff explaining what a helm rollback would change:
    This fetches the currently deployed version of a release
  and compares it to adeployed versions of a release, that you 
  want to rollback. This can be used visualize what changes a 
  helm rollback will perform.

Usage:
  diff [flags]
  diff [command]

Available Commands:
  release     Shows diff between release's manifests
  revision    Shows diff between revision's manifests
  rollback    Show a diff explaining what a helm rollback could perform
  upgrade     Show a diff explaining what a helm upgrade would change.
  version     Show version of the helm diff plugin

Flags:
      --allow-unreleased             enables diffing of releases that are not yet deployed via Helm

      --devel                        use development versions, too. Equivalent to version '>0.0.0-0'. If --version is set, this is ignored.
      --disable-openapi-validation   disables rendered templates validation against the Kubernetes OpenAPI Schema
      --disable-validation           disables rendered templates validation against the Kubernetes cluster you are currently pointing to. This is the same validation performed on an install
      --dry-run                      disables cluster access and show diff as if it was install. Implies --install, --reset-values, and --disable-validation
  -h, --help                         help for diff
      --include-tests                enable the diffing of the helm test hooks
