nice PR @andrcuns! How do you check if UI test is ready to run on running healthy container? do you put logic like docker ps | grep "something" and then if status is healthy then run UI test? because it might be helpful for others.

[andrcuns]

In our particular case we have a project that uses gradle as a build tool and I utilize docker-compose-gradle-plugin which has functionality for health check built in.
Can't much comment on any other solution as this project is the first one for me where I use docker containers.
But I would assume that polling for status either via docker ps or docker inspect should work. Or quick google search shows that this will work in getting it in json format: docker inspect --format='{{json .State.Health}}' your-container-name

I will merge it and include this fix to next release.
