Tofu-Controller-Runner Overview

Secure your stack with a hardened Tofu-Controller-Runner image freshly-built by Minimus. Minimus images always include the most up-to-date package version for all packages and dependencies contained in the image.

Tofu-Controller-Runner is the execution image that Tofu-Controller spawns as a short-lived pod for each OpenTofu or Terraform reconciliation — it receives plan and apply requests over an mTLS-secured gRPC connection from the controller, then runs the actual OpenTofu or Terraform commands against the target infrastructure. Bundling the OpenTofu CLI with Git and SSH client tooling lets each reconciliation fetch its configuration and execute it in an isolated, disposable pod without additional init containers.

Try It Out

Tofu-Controller-Runner can be deployed via a Helm chart. See the related charts tab to get started.

Run a quick test

For a quick test, print the help menu:

docker run --rm reg.mini.dev/tofu-controller-runner --help

In production, Tofu-Controller launches runner pods automatically — the image reference is set through the runner.image.repository and runner.image.tag values in the Tofu-Controller Helm chart.

Technical Considerations

The Tofu-Controller-Runner image provided by Minimus is a slim, security-hardened alternative to the public image from GitHub Container Registry. The images are largely interchangeable, with a few differences as noted below.

Tofu-Controller-Runner built by Minimus:

Runs as non-root by default (uid 65532), matching the public image's default non-root user.
Drill down on the version specification tab to see the default user, listening ports, entrypoint, volumes, environment variables, etc.

The Payoff

A hardened, minimal image that will remain more secure for the long run and accrue vulnerabilities at a slower rate.

See the risk reduction dashboard for a detailed CVE comparison over the past 30 days.
Review the compliance report to see the default hardening and security configurations for the image.
