k is the CLI tool used to interact with the Reclaim the Stack platform. It wraps kubectl and some other CLI tools and interfaces with configured ArgoCD gitops repos.

Note: A recent version of ruby is recommended to run k. You may get away with the MacOS default Ruby installation but there are probably commands which won't work correctly. We recommend a version manager such as rbenv to install and use the latest Ruby version. Once things stabilize we'll likely package k with a pre-baked Ruby runtime to avoid the dependency.

Via Homebrew

brew install --HEAD reclaim-the-stack/tap/k

Without Homebrew

Install the dependencies: kubectl

Then download the latest k release package and put it in your PATH.

The first step when using k will be to configure a "context". A context is a combination of:

1. A GitHub repository containing ArgoCD platform and applications manifests
2. A Kubernetes cluster (ie. a locally configured kubectl context)
3. A Docker registry + namespace containing Docker images to be deployed as applications

Run k contexts:add <github-gitops-url> to add your first context.

Note that k stores all its configuration in YAML at ~/.k/config. Feel free to inspect this file and make changes by hand if you so desire.

Run k to get a list of commands.

We don't provide any rigorous documentation as of yet. If you've used the Heroku CLI tool a lot of things will seem familiar. Feel free to explore the available commands and provide feedback if something is hard to understand or broken.
