Issue
I am newbie in docker,noticed below command while referring a document to install jenkins in docker.
docker run -p 8080:8080 -p 50000:50000 -v /your/home:/var/jenkins_home jenkins
Solution
-p <source>:<dest> or --publish <source>:<dest>, create a forwarding rule from your <docker-host>:<source> to <container>:<dest>.
If used multiple times, it creates multiple forwarding rules.
In your example, the traffic from <host-machine-IP-addr>:8080, is forwarded inside the Jenkins container, to the service that's is listening on :8080.
Exactly the same thing is happening with port :50000.
Basically the container's Jenkins web UI is exposed on the host machine on 8080, while the Jenkins slave port is also exposed on you host machine on 50000.
