Drone 0.6 plugin to use create and deploy Helm charts for Kubernetes and push Helm package to Google Storage. You will need to generate a JSON token to authenticate to the Kuebernetes cluster and to push Helm package to the Google Storage.

The following parameters are used to configure this plugin:

• debug - enable debug mode.
• show_env - outputs a list of env vars without values.
• wait - Wait until all Pods, PVCs, Services, and min number of Pods of a Deployment are in a ready state before marking the release as successful.
• wait_timeout - Time in seconds to wait for any individual kubernetes operation (like Jobs for hooks) (default 300).
• recreate-pods - If true, uses helm upgrade with the recreate-pods flag.
• actions - list of actions over chart - lint, create, push, deploy. Required and order is important (except lint).
• zone - zone of the Kubernetes cluster.
• cluster - the Kubernetes cluster name.
• project - the Google project identifier.
• namespace - the Kubernetes namespace to install in.
• bucket - the Google Storage Bucket name to push Helm package into it.
• chart_repo - the Helm charts repository (defaul ig https://$(BUCKET).storage.googleapis.com/)
• chart_path - the path to the Helm chart (e.g. chart/foo).
• chart_version - the version of the chart.
• package - the package name. Default is chart name.
• release - the release name used for helm upgrade. Defaults to package name.
• values - list of chart values. Would be set via --set Helm flag.

Auth Key Management:

Add a new secret, containing your JSON token to your project

drone secret add --image=gcr.io/lovoo-ci/drone-gcloud-helm:1.1.0 --name=AWESOME_GCLOUD_TOKEN --value=@/path/to/your/token.json octocat/helloworld

configure the drone-gcloud-helm plugin in your .drone.yaml to use your secret and alias it to plugin_auth_key

  secrets:
    - source: AWESOME_GCLOUD_TOKEN
      target: plugin_auth_key

Sample configuration:

deploy:
  image: foobar/drone-gcloud-helm
  debug: true
  actions:
    - lint
    - create
    - push
    - deploy
  chart_path: chart/foo
  chart_version: ${DRONE_BUILD_NUMBER}
  project: foo-project
  cluster: foo-cluster-1
  zone: europe-west1-b
  bucket: foo-charts
  secrets:
    - source: AWESOME_GCLOUD_TOKEN
      target: plugin_auth_key
  values:
    - "docker.tag=${DRONE_BUILD_NUMBER}"
  when:
    branch: master
    event: push

Sample configuration for linting only:

lint:
  image: foobar/drone-gcloud-helm
  actions:
    - lint
  chart_path: chart/foo
  when:
    branch: master
    event: push
