Terraform Provider for Helm

This is a Helm provider for Terraform.

The provider manages the installed Charts in your Kubernetes cluster, in the same way Helm does, through Terraform.

⚠️ Project Update: Helm 3

The latest release 1.0.0 for this provider brings support for Helm 3. This is a breaking change that removes support for Helm 2 and tiller. If you are still using Helm 2 see the section below.

Helm 2 support

If you are still using Helm 2 and tiller you will have to pin your provider version to the latest 0.10.x release.

We will continue to accept bugfixes for the 0.10.x version of the provider, please open your pull request against the latest release-0.10.x branch.

Developing the Provider

Installation from sources

If you wish to compile the provider from source code, you'll first need Go installed on your machine (version >=1.9 is required). You'll also need to correctly setup a GOPATH, as well as adding $GOPATH/bin to your $PATH.

Clone repository to: $GOPATH/src/github.com/terraform-providers/terraform-provider-helm

> mkdir -p $GOPATH/src/github.com/terraform-providers
> git clone https://github.com/terraform-providers/terraform-provider-helm.git $GOPATH/src/github.com/terraform-providers/terraform-provider-helm

Enter the provider directory and build the provider

> cd $GOPATH/src/github.com/terraform-providers/terraform-provider-helm
> make build

Now copy the compiled binary to the Terraform's plugins folder, if is your first plugin maybe isn't present.

> mkdir -p ~/.terraform.d/plugins/
> mv terraform-provider-helm ~/.terraform.d/plugins/

Example

This is a small example of how to install the mariadb chart on your default kubernetes cluster, since the provider was initialized, all the configuration is retrieved from the environment. Please read the documentation for more information.

You should have a local configured copy of kubectl.

resource "helm_release" "my_database" {
    name      = "my-database"
    chart     = "stable/mariadb"

    set {
        name  = "mariadbUser"
        value = "foo"
    }

    set {
        name = "mariadbPassword"
        value = "qux"
    }

    set_string {
        name = "image.tags"
        value = "registry\\.io/terraform-provider-helm\\,example\\.io/terraform-provider-helm"
    }
}
