The first time you run the container, you should give it a name. This first run will initialize the database. Following runs should reference the volumes to pick up the changes you made.
docker run --name=manageiq -d -P kullervo16/manageiq
Once completely initialized, you can access it (this may take some time). When running later, use this command :
docker run --rm --volumes-from=manageiq -p 3000:3000 kullervo16/manageiq
The interface is exposed at port 3000. The login is admin with pwd smartvm. You can change this or course.
Have fun with it...
The Dockerfile and the scripts can be found on https://github.com/kullervo16/manageiq
