Try it from Docker

Want to run OpenPaaS with Docker? This is easy with the help of docker-compose! Once you have the sources, just run:
PROVISION=true DOCKER_IP=[YOUR_DOCKER_IP] ESN_PATH=$PWD docker-compose -f ./docker/dockerfiles/platform/docker-compose-images.yml up
Where YOUR_DOCKER_IP is localhost on linux and probably if you use the default docker machine on OS X and Windows. ​
Launching the platform may take some time (1-2 minutes), grab a coffee and be ready for the next steps!​
