I created a docker container which is running 2 java processes – one of the processes is listening on port 4444 and should have access from browser hitting the following URL:
http://{host}:4444/grid/console
How do I hit this URL from my browser on the host – connect to the container on port 4444?
This is the response from docker inspect:

Answer
As you can see from the output in your question, your container’s ip address is 172.17.0.2. Just point your browser at http://172.17.0.2:4444.
Alternately, you could forward this to a host port, as in:
docker run -p 4444:4444 ...
And then on your host run you could access localhost:4444.
