    You’re mapping the port 9090 of the host, in this case your local computer, to the container port of 8000. In other words: You should be able to reach it locally on port 9090

    you could access it in http://localhost:9090.
    8000 is the port inside your docker container not accessible from outside.
    The local port is 9090
