First, build and push a container image extending our official image with the following:

- Terraform [(supported versions)](https://github.com/coder/coder/blob/main/provisioner/terraform/install.go#L23-L24)
- CLI config (.tfrc) for Terraform referring to [external mirror](https://www.terraform.io/cli/config/config-file#explicit-installation-method-configuration)
- [Terraform Providers](https://registry.terraform.io) for templates
- These could also be specified via a volume mount (Docker) or [network mirror](https://www.terraform.io/internals/provider-network-mirror-protocol). See below for details.

> Note: Coder includes the latest [supported version](https://github.com/coder/coder/blob/main/provisioner/terraform/install.go#L23-L24) of Terraform in the official Docker images.
> If you need to bundle a different version of terraform, you can do so by customizing the image.
