For example, run `gcloud auth application-default login` to\nimport credentials on the system and user running coderd. For other ways to\nauthenticate [consult the Terraform\ndocs](https://registry.terraform.io/providers/hashicorp/google/latest/docs/guides/getting_started#adding-credentials).\n\nCoder requires a Google Cloud Service Account to provision workspaces. To create\na service account:\n\n1. Navigate to the [CGP\n console](https://console.cloud.google.com/projectselector/iam-admin/serviceaccounts/create),\n and select your Cloud project (if you have more than one project associated\n with your account)\n\n1. Provide a service account name (this name is used to generate the service\n account ID)\n\n1. Click **Create and continue**, and choose the following IAM roles to grant to\n the service account:\n\n - Compute Admin\n - Service Account User\n\n Click **Continue**.\n\n1. Click on the created key, and navigate to the **Keys** tab.\n\n1. Click **Add key** \u003e **Create new key**.\n\n1. Generate a **JSON private key**, which will be what you provide to Coder\n during the setup process.\n\n## Architecture\n\nThis template provisions the following resources:\n\n- Envbuilder cached image (conditional, persistent) using [`terraform-provider-envbuilder`](https://github.com/coder/terraform-provider-envbuilder)\n- GCP VM (persistent) with a running Docker daemon\n- GCP Disk (persistent, mounted to root)\n- [Envbuilder container](https://github.com/coder/envbuilder) inside the GCP VM\n\nCoder persists the root volume. The full filesystem is preserved when the workspace restarts.\nWhen the GCP VM starts, a startup script runs that ensures a running Docker daemon, and starts\nan Envbuilder container using this Docker daemon. The Docker socket is also mounted inside the container to allow running Docker containers inside the workspace.\n\n\u003e **Note**\n\u003e This template is designed to be a starting point! Edit the Terraform to extend the template to support your use case.\n\n## Caching\n\nTo speed up your builds, you can use a container registry as a cache.\nWhen creating the template, set the parameter `cache_repo` to a valid Docker repository in the form `host.tld/path/to/repo`.\n\nSee the [Envbuilder Terraform Provider Examples](https://github.com/coder/terraform-provider-envbuilder/blob/main/examples/resources/envbuilder_cached_image/envbuilder_cached_image_resource.tf/) for a more complete example of how the provider works.\n\n\u003e [!NOTE] We recommend using a registry cache with authentication enabled.\n\u003e To allow Envbuilder to authenticate with the registry cache, specify the variable `cache_repo_docker_config_path`\n\u003e with the path to a Docker config `.json` on disk containing valid credentials for the registry.\n\n## code-server\n\n`code-server` is installed via the [`code-server`](https://registry.coder.com/modules/code-server) registry module. Please check [Coder Registry](https://registry.coder.com) for a list of all modules and templates.\n"

- Envbuilder cached image (conditional, persistent) using [`terraform-provider-envbuilder`](https://github.com/coder/terraform-provider-envbuilder)

- Docker image (persistent) using [`envbuilder`](https://github.com/coder/envbuilder)

- Envbuilder cached image (conditional, persistent) using [`terraform-provider-envbuilder`](https://github.com/coder/terraform-provider-envbuilder)

- GCP VM (persistent) with a running Docker daemon

- [Envbuilder container](https://github.com/coder/envbuilder) inside the GCP VM

When the GCP VM starts, a startup script runs that ensures a running Docker daemon, and starts

an Envbuilder container using this Docker daemon. The Docker socket is also mounted inside the container to allow running Docker containers inside the workspace.

To speed up your builds, you can use a container registry as a cache.

When creating the template, set the parameter `cache_repo` to a valid Docker repository in the form `host.tld/path/to/repo`.

See the [Envbuilder Terraform Provider Examples](https://github.com/coder/terraform-provider-envbuilder/blob/main/examples/resources/envbuilder_cached_image/envbuilder_cached_image_resource.tf/) for a more complete example of how the provider works.
