For the usage information and a listing of the available options please take a look at the docs.

Run the local image (or replace drone-helm with quay.io/ipedrazas/drone-helm:

docker run --rm \
  -e API_SERVER="https://$(minikube ip):8443" \
  -e KUBERNETES_TOKEN="${KUBERNETES_TOKEN}" \
  -e PLUGIN_NAMESPACE=default \
  -e PLUGIN_SKIP_TLS_VERIFY=true \
  -e PLUGIN_RELEASE=my-release \
  -e PLUGIN_CHART=stable/redis \
  -e PLUGIN_VALUES="tag=TAG,api=API" \
  -e PLUGIN_STRING_VALUES="long_string_value=1234567890" \
  -e PLUGIN_DEBUG=true \
  -e PLUGIN_DRY_RUN=true \
  -e DRONE_BUILD_EVENT=push \
  quay.io/ipedrazas/drone-helm

Troubleshooting

If you see this problem: Error: API Server is needed to deploy. It's usually because you haven't a secret that specifies the API_SERVER or the KUBERNETES_TOKEN.

As one000mph commented in an issue, setting the right PREFIX and secrets usually solves the problem.

export ACTION=add
    export REPO=org/myrepo
    export PREFIX=prod_
    # export CLUSTER_URI, UNENCODED_TOKEN, BASE64_CERT
    drone secret $ACTION --repository $REPO --name "${PREFIX}api_server" --value $CLUSTER_URI
    drone secret $ACTION --repository $REPO --name "${PREFIX}kubernetes_token" --value $UNENCODED_TOKEN
    drone secret $ACTION --repository $REPO --name "${PREFIX}kubernetes_certificate" --value $BASE64_CERT```

Contribution

This repo is setup in a way that if you enable a personal drone server to build your fork it will build and publish your image (makes it easier to test PRs and use the image till the contributions get merged)

• Build local DRONE_REPO_OWNER=ipedrazas DRONE_REPO_NAME=drone-helm drone exec
• on your server just make sure you have DOCKER_USERNAME, DOCKER_PASSWORD, and DOCKERHUB_REPO set as secrets
