Control plane

A control plane acts as an API for provisioning and managing infrastructure. Well-known examples include AWS itself and Kubernetes (K8s).

There is a blog article about this proof of concept.

Requirements

ctlp (control plane) requires Clojure. It doesn’t work with Babashka. Direnv is not required but it is convinient.

brew

brew install clojure/tools/clojure

devbox

devbox global add clojure

Getting started

The best way to learn how it works is to install the Clojure tool in development mode.

1. Clone the repo

   git clone -b control-plane https://github.com/amiorin/big-config.git big-config/control-plane && cd big-config/control-plane

2. Add ctrlp as tool to Clojure

   clojure -Ttools install big-config/control-plane '{:local/root "."}' :as ctlp

3. Show help

   alias p="clojure -Tctlp"
   p help

  • control_plane.clj The CLI tool.
  • prevayler.clj The vendored library used for persistency.
• .envrc Direnv file to load the AWS env vars.
