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 to 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 to 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 the previously deployed version of the release, that you
  want to rollback. This can be used to visualize what changes a
  helm rollback will perform.

Usage:
  diff [flags]
  diff [command]

Available Commands:
  completion  Generate the autocompletion script for the specified shell
  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
  -a, --api-versions stringArray                 Kubernetes api versions used for Capabilities.APIVersions
      --color                                    color output. You can control the value for this flag via HELM_DIFF_COLOR=[true|false]. If both --no-color and --color are unspecified, coloring enabled only when the stdout is a term and TERM is not "dumb"
  -C, --context int                              output NUM lines of context around changes (default -1)
      --detailed-exitcode                        return a non-zero exit code when there are changes
      --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 string[="client"]                --dry-run, --dry-run=client, or --dry-run=true disables cluster access and show diff as if it was install. Implies --install, --reset-values, and --disable-validation. --dry-run=server enables the cluster access with helm-get and the lookup template function.
      --enable-dns                               enable DNS lookups when rendering templates
  -D, --find-renames float32                     Enable rename detection if set to any value greater than 0. If specified, the value denotes the maximum fraction of changed content as lines added + removed compared to total lines in a diff for considering it a rename. Only objects of the same Kind are attempted to be matched
  -h, --help                                     help for diff
      --include-crds                             include CRDs in the diffing
      --include-tests                            enable the diffing of the helm test hooks
      --insecure-skip-tls-verify                 skip tls certificate checks for the chart download
      --install                                  enables diffing of releases that are not yet deployed via Helm (equivalent to --allow-unreleased, added to match "helm upgrade --install" command
      --kube-version string                      Kubernetes version used for Capabilities.KubeVersion
      --kubeconfig string                        This flag is ignored, to allow passing of this top level flag to helm
      --no-color                                 remove colors from the output. If both --no-color and --color are unspecified, coloring enabled only when the stdout is a term and TERM is not "dumb"
      --no-hooks                                 disable diffing of hooks
      --normalize-manifests                      normalize manifests before running diff to exclude style differences from the output
      --output string                            Possible values: diff, simple, template, dyff. When set to "template", use the env var HELM_DIFF_TPL to specify the template. (default "diff")
      --post-renderer string                     the path to an executable to be used for post rendering. If it exists in $PATH, the binary will be used, otherwise it will try to look for the executable at the given path
      --post-renderer-args stringArray           an argument to the post-renderer (can specify multiple)
      --repo string                              specify the chart repository url to locate the requested chart

      --set-string stringArray                   set STRING values on the command line (can specify multiple or separate values with commas: key1=val1,key2=val2)
      --show-secrets                             do not redact secret values in the output

      --skip-schema-validation                   skip validation of the rendered manifests against the Kubernetes OpenAPI schema

      --suppress stringArray                     allows suppression of the kinds listed in the diff output (can specify multiple, like '--suppress Deployment --suppress Service')
