a library to define a continuous delivery pipeline in code


  • it’s a continuous delivery pipeline, in code
  • it’s your own custom built Jenkins/Go/TeamCity/…, in clojure

This project is still under active development so don’t rely on everything working flawlessly out of the box. Also, things might change along the way so when you upgrade, make sure you check out the changelog

However, people do use LambdaCD in their day to day work and are happy with it, so give it a try! And if you notice something, please open bug reports, feature requests or just give feedback!


  • Make sure you have Leiningen and a recent version of JDK installed
  • lein new lambdacd <NAME> will create a new pipeline-project
  • cd <NAME>
  • lein run downloads all dependencies and starts the server; the UI is then served on on http://localhost:8080
  • your pipeline is defined in src/<NAME>/. Have a look around, change some steps or add some steps on your own.

LambdaCD is built in Clojure and ClojureScript with Leiningen as a build-tool. The ./go script is your main entry-point that wraps all important development tasks. Call it without arguments to see all the options.

General Setup

  • Call ./go setup to install necessary dependencies and build everything once.

Core Development

  • Sources for the core of LambdaCD can be found in src/clj, tests in test/clj.
  • Run tests with ./go test-clj
  • To run a sample-pipeline (see example/clj), run ./go serve. You may have to run ./go serve-cljs occasionally to generate the frontend JS code from ClojureScript.
  • If you want the example pipeline to be green (which is not necessary for all development), you first need to setup a mock-deployment environment on your machine (two VMs where we deploy a TodoMVC client and server):
    • install Vagrant
    • have github-access set up (you need to be able to clone with ssh)
    • ./go setupTodopipelineEnv starts up two VMs in vagrant where we deploy to and exports the ssh-config for them so that it can be used by the deployment scripts

Frontend Development

  • The frontend is written in ClojureScript using Reagent and re-frame
  • Frontend resources can be found in resources/public, ClojureScript code in src/cljs, tests in test/cljs
  • Stylesheets are written in are in Less and can be found in src/less
  • ClojureScript code needs to be compiled into JS before being useful
  • In three terminals, run ./go serve to start an example pipeline (if you want it to be green, follow the environment setup above), ./go serve-cljs to start a ClojureScript REPL and automatic code-reloading using Figwheel and ./go serve-css to run the css autoprefixer watch
  • Run ./go test-cljs to run frontend-tests or ./go test-cljs-auto to start autotest
