Docker Compose file for running Clojure Koans

docker-compose.yml

koans:
  image: clojure
  command: lein koan run
  volumes:
    - ./clojure-koans:/clojure-koans
  working_dir: /clojure-koans
  
repl:
  image: clojure
  command: lein repl
  volumes:
    - ./clojure-koans:/clojure-koans
  working_dir: /clojure-koans

To use this file:

# Resolve host dependencies, and boot a local Docker environment
brew install docker docker-compose docker-machine
docker-machine start && eval $(docker-machine env)

# Create a new folder, and download the docker-compose file into it
mkdir clj-koans && cd clj-koans
curl -o https://gist.githubusercontent.com/seeflanigan/5b72636d6e8881138919/raw/f394b2beb2d0b459c2b1fc51c42e1c7471e2c3a0/docker-compose.yml

# Resolve project dependencies, and clone the clojure-koans repository
docker-compose pull
git clone git://github.com/functional-koans/clojure-koans.git
docker-compose run koans

# Run a REPL
docker-compose run repl

The docker-compose run koans command instantiates a long-running test process, which automatically re-runs tests when you edit the koan source files. It loads dependencies once, per instance. The REPL does not automatically update when source files are changed.
