Tomcat running in Docker container (Debian host) not reachable from the host

I followed the instructions on Docker Hub for the tomcat image (https://hub.docker.com/_/tomcat)

So I pulled the image

docker pull tomcat:9.0

and started it as described

docker run -it --rm -p 8888:8080 tomcat:9.0

According to the docs, this should show a 404 error page from Tomcat on the host machine when opening http://localhost:8888

But instead the browser keeps loading and eventually times out.

What am I missing here? From docker inspect I can see that the container exposes the port

        "Config": {
            ...
            "ExposedPorts": {
                "8080/tcp": {}
            },
            ...
         }

EDIT:

Container is running

thomas@debian:~$ docker ps

Solution

  • Looks like VMWare messed things up

    After reverting back to an earlier snapshot and then back to the latest one, everything started to work just fine
