CloudStack Terraform Provider

Requirements

• Terraform 1.0.x
• Go 1.20+ (to build the provider plugin)

See wiki: https://github.com/apache/cloudstack-terraform-provider/wiki

Installing from Github Release

User can install the CloudStack Terraform Provider using the Github Releases with the installation steps below.

Replace the RELEASE version with the version you're trying to install and use.

The valid ARCH options are:

• linux_amd64
• linux_386
• linux_arm64
• linux_arm
• darwin_amd64
• darwin_arm64
• freebsd_amd64
• freebsd_386
• freebsd_arm64
• freebsd_arm

Steps for installation:

RELEASE=0.5.0
ARCH=darwin_arm64
mkdir -p ~/.terraform.d/plugins/local/cloudstack/cloudstack/${RELEASE}/${ARCH}
wget "https://github.com/apache/cloudstack-terraform-provider/releases/download/v${RELEASE}/cloudstack-terraform-provider_${RELEASE}_${ARCH}.zip"
unzip cloudstack-terraform-provider_${RELEASE}_${ARCH}.zip -d cloudstack-terraform-provider_${RELEASE}
mv cloudstack-terraform-provider_${RELEASE}/cloudstack-terraform-provider_v${RELEASE} ~/.terraform.d/plugins/local/cloudstack/cloudstack/${RELEASE}/${ARCH}/terraform-provider-cloudstack_v${RELEASE}

To use the locally installed provider, please use the following in your main.tf etc, and then run terraform init:

terraform {
  required_providers {
    cloudstack = {
      source = "local/cloudstack/cloudstack"
      version = "0.5.0"
    }
  }
}

provider "cloudstack" {
  # Configuration options
}

Note: this can be used when users are not able to install using the Terraform registry.

Installing from Terrafrom registry

To install the CloudStack provider, copy and paste the below code into your Terraform configuration. Then, run terraform init.

terraform {
  required_providers {
    cloudstack = {
      source = "cloudstack/cloudstack"
      version = "0.5.0"
    }
  }
}

provider "cloudstack" {
  # Configuration options
}

User hitting installation issue using registry can install using the local install method.

Developing the Provider

If you wish to work on the provider, you'll first need Go installed on your machine (version 1.16+ 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/apache/cloudstack-terraform-provider

$ mkdir -p $GOPATH/src/github.com/apache; cd $GOPATH/src/github.com/apache
$ git clone git@github.com:apache/cloudstack-terraform-provider

To compile the provider, run make build. This will build the provider and put the provider binary in the $GOPATH/bin directory.

Enter the provider directory and build the provider

$ cd $GOPATH/src/github.com/apache/cloudstack-terraform-provider
$ make build
$ ls $GOPATH/bin/terraform-provider-cloudstack

Once the build is ready, you have to copy the binary into Terraform locally (version appended).

On Linux and Mac this path is at ~/.terraform.d/plugins, On Windows at %APPDATA%\terraform.d\plugins,

$  cd ~
$  mkdir -p ~/.terraform.d/plugins/localdomain/provider/cloudstack/0.4.0/linux_amd64
$  cp $GOPATH/bin/terraform-provider-cloudstack ~/.terraform.d/plugins/localdomain/provider/cloudstack/0.4.0/linux_amd64

Testing the Provider

In order to test the provider, you can simply run make test.

$ make test

In order to run the full suite of Acceptance tests you will need to run the CloudStack Simulator. Please follow these steps to prepare an environment for running the Acceptance tests:

docker pull apache/cloudstack-simulator

or pull it with a particular build tag

docker pull apache/cloudstack-simulator:4.19.0.0

docker run --name simulator -p 8080:5050 -d apache/cloudstack-simulator

or

docker run --name simulator -p 8080:5050 -d apache/cloudstack-simulator:4.19.0.0

When Docker started the container you can go to http://localhost:8080/client and login to the CloudStack UI as user admin with password password. It can take a few minutes for the container is fully ready, so you probably need to wait and refresh the page for a few minutes before the login page is shown.

Once the login page is shown and you can login, you need to provision a simulated data-center:

docker exec -it cloudstack-simulator python /root/tools/marvin/marvin/deployDataCenter.py -i /root/setup/dev/advanced.cfg

If you refresh the client or login again, you will now get passed the initial welcome screen and be able to go to your account details and retrieve the API key and secret. Export those together with the URL:

$ export CLOUDSTACK_API_URL=http://localhost:8080/client/api
$ export CLOUDSTACK_API_KEY=r_gszj7e0ttr_C6CP5QU_1IV82EIOtK4o_K9i_AltVztfO68wpXihKs2Tms6tCMDY4HDmbqHc-DtTamG5x112w
$ export CLOUDSTACK_SECRET_KEY=tsfMDShFe94f4JkJfEh6_tZZ--w5jqEW7vGL2tkZGQgcdbnxNoq9fRmwAtU5MEGGXOrDlNA6tfvGK14fk_MB6w

In order for all the tests to pass, you will need to create a new (empty) project in the UI called terraform. When the project is created you can run the Acceptance tests against the CloudStack Simulator by simply running:

$ make testacc

Sample Terraform configuration when testing locally

Below is an example configuration to initialize provider and create a Virtual Machine instance

$ cat provider.tf
terraform {
  required_providers {
    cloudstack = {
      source = "localdomain/provider/cloudstack"
      version = "0.4.0"
    }
  }
}

provider "cloudstack" {
  # Configuration options
  api_url    = var.cloudstack_api_url
  api_key    = var.cloudstack_api_key
  secret_key = var.cloudstack_secret_key
}

resource "cloudstack_instance" "web" {
  name             = "server-1"
  service_offering = "Small Instance"
  network_id       = "df5fc279-86d5-4f5d-b7e9-b27f003ca3fc"
  template         = "616fe117-0c1c-11ec-aec4-1e00610002a9"
  zone             = "2b61ed5d-e8bd-431d-bf52-d127655dffab"
}

Releasing Terraform Provider

The CloudStack Terraform Provider release process requires goreleaser to be performed by a committer or a PMC member of the project: https://goreleaser.com/install

Check and ensure TF provider passes builds, GA and run this for local checks:

goreleaser release --snapshot --clean

Next, create a personalised Github token:
 https://github.com/settings/tokens/new?scopes=repo,write:packages

export GITHUB_TOKEN="YOUR_GH_TOKEN"

Note: Due to how the Terraform registry works, it require the repo to be named in a certain way. For this reason, the builds are published via https://github.com/cloudstack/terraform-provider-cloudstack/releases

To do this, add the following remote for publishing builds:

git remote add cloudstack git@github.com:cloudstack/terraform-provider-cloudstack.git

Finally tag the release, for example and push to Github:

git tag -a v0.5.0-pre -m "v0.5.0-pre Alpha Release for testing purposes"
git push cloudstack v0.5.0-pre

Run goreleaser to release them:

goreleaser release --clean

Or, just release using:

goreleaser release

For testing or to push on other repos, you need to fix repo path in the .goreleaser.yml and run:

goreleaser release --clean --skip-validate
