How to install docker metabase on linux?

Question

I have a problem to install docker version of metabase on linux computer, I try to follow this tutorial but don't clearly understand why that metabase still not open

Answer 1

I found that it must be docker run -d -p 2947:3000 --name metabase metabase/metabase

that 2947 is a port that we can access outside the "metabase" container, and 3000 is the port to access inside the "metabase" container. So since metabase is installed defaultly in port 3000, replacing the "inside port (3000)" effect that metabase cannot accessed in my case. Probably it because the docker aim the wrong port, so it return nothing
