The [envbuilder Terraform provider](https://github.com/coder/terraform-provider-envbuilder) will check the contents of the cache to determine if a prebuilt image exists. In the case of some missing layers in the registry (partial cache miss), Envbuilder can still utilize some of the build cache from the registry.\n\n### Authentication\n\nThis template authenticates using a `~/.kube/config`, if present on the server, or via built-in authentication if the Coder provisioner is running on Kubernetes with an authorized ServiceAccount. To use another [authentication method](https://registry.terraform.io/providers/hashicorp/kubernetes/latest/docs#authentication), edit the template.\n\n## Architecture\n\nCoder supports devcontainers with [envbuilder](https://github.com/coder/envbuilder), an open source project.
