Install

rackctl is a single static Go binary. It ships for macOS and Linux, on both amd64 and arm64.

Install script

The quickest path. Downloads the release archive for your platform, verifies it against the published checksums.txt, and installs rackctl to /usr/local/bin.

curl -fsSL rackctl.com/install | sh

Prefer to read before you run? The script lives in the repo at scripts/install.sh. Pipe it to a file, inspect it, then run it.

Homebrew

brew install rackctl/tap/rackctl

The formula in rackctl/homebrew-tap is published automatically by goreleaser on every release.

From source

Requires Go 1.26 or newer.

git clone https://github.com/rackctl/rackctl
cd rackctl
make build          # -> ./dist/rackctl
# or install onto your PATH:
go install github.com/rackctl/rackctl@latest

Prerequisites

rackctl orchestrates the tools you already use to run a platform — it doesn’t bundle them. Install these and make sure they’re on your PATH:

Tool	Used for
tofu	OpenTofu — provisions the AWS substrate
terragrunt	Wraps the landing-zone Terragrunt components
kubectl	Talks to the EKS cluster
helm	Installs the operator and addon charts
aws	AWS CLI — identity, quotas, and API calls
git	Clones and manages the platform repos
gh	GitHub CLI — forks the org repos

Run rackctl doctor to confirm they’re all present and that your AWS identity resolves before you provision anything.
