Helm 3 renamed the command, and I didn't realize it until just now.

See also 161960e, where it was renamed in the code.

Drone plugin for Helm 3

This plugin provides an interface between Drone and Helm 3:

Lint your charts
Deploy your service
Delete your service

The plugin is inpsired by drone-helm, which fills the same role for Helm 2. It provides a comparable feature-set and the configuration settings are backwards-compatible.

Example configuration

These examples give a minimal and sufficient configuration for each use-case. For a full description of each case, see docs/lint_example.yml, docs/upgrade_example.yml, and docs/uninstall_example.yml.

Linting

steps:
  - name: lint
    image: pelotech/drone-helm3
    settings:
      helm_command: lint
      chart: ./

Deployment

steps:
  - name: deploy
    image: pelotech/drone-helm3
    settings:
      helm_command: upgrade
      chart: ./
      release: my-project
    environment:
      API_SERVER: https://my.kubernetes.installation/clusters/a-1234
      KUBERNETES_TOKEN:
        from_secret: kubernetes_token

Deletion

steps:
  - name: uninstall
    image: pelotech/drone-helm3
    settings:
      helm_command: uninstall
      release: my-project
    environment:
      API_SERVER: https://my.kubernetes.installation/clusters/a-1234
      KUBERNETES_TOKEN:
        from_secret: kubernetes_token

Upgrading from drone-helm

The setting names for drone-helm3 are backwards-compatible with those for drone-helm, so the only mandatory step is to update the image clause so that drone uses the new plugin.

There are several settings that no longer have any effect:

purge -- this is the default behavior in Helm 3
recreate_pods
tiller_ns
upgrade
canary_image
client_only
stable_repo_url

If your .drone.yml contains those settings, we recommend removing them.
