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" \

  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
