This is a Helm provider for Terraform.

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

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.

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

Enter the provider directory and build the provider

> cd $GOPATH/src/github.com/mcuadros/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 retrieve 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"
    }
}
