Has anyone got the metabase image to run under Centos 7.3?

I have installed Docker on a server running CENTOS 7.3. The hello-world image runs alright, so I think that Docker is OK.

If I create and run a metabase container using-

docker run -d -p 3000:3000 --name metabase metabase/metabase

then I am unable to connect via port 3000. In other words, the URL-

mywebsite:3000

gives nothing at all.

The ISP says that Docker is listening on port 3000.

Has anybody made this work?

Is Docker an absolute requirement?

Could you try running the jar and see if it stands up the environment?
