Kubernetes Helm Multi-Deploy

⚠️ This action's docker image is built at runtime.

For a pre-built docker-based action with all dependencies included see here

For a no-docker action which requies all dependencies be installed in the GitHub Docker see here

This GitHub Action will deploy all Helm chart folders inside a 'deployment' folder in your repository root. Useful for deploying multiple services that are in separate charts. For example:

my-awesome-app/
├── README.md
├── deployment
│   ├── my-deployment-1
│   │   ├── Chart.yaml
|   |   ├── requirements.yaml
│   │   ├── values-dev.yaml
│   │   ├── values-prod.yaml
│   │   └── values.yaml
│   └── my-deployment-2
│       ├── Chart.yaml
│       ├── values-dev.yaml
│       ├── values-prod.yaml
│       └── values.yaml
└── src
    └── etc

For the above file system, this action will deploy my-deployment-1, my-deployment-2, and any other charts under the deployment folder. Each chart can contain subcharts too.

If you define the input environment-slug, then values-<env>.yaml will be applied on top of your values.yml. e.g. if you define environment-slug=dev, then the options -f values.yaml -f values-dev.yaml will be passed to helm (if values-dev.yaml exists). This is to provide the option of having different settings per environment.
