-Crankshaft comes with a Dockerfile to build and run a sandboxed machine for testing
-and development.
-
-First you have to build the docker container
-
-    docker build -t crankshaft .
-
-To run the pg tests run
-
-    docker run -it --rm -v $(pwd):/crankshaft  crankshaft /root/run_tests.sh
-
-if there are failures it will dump the reasion to the screen.
-
-To run a server you can develop on run
-
-    docker run -it --rm -v $(pwd):/crankshaft -p $(docker-machine ip default):5432:5432 /root/run_server.sh
-
-and connect from you host using
