Docker Run displays an invalid URL for accessing the image

[tylere]

What docker image you are using?

jupyter/scipy-notebook:03b897d05f16

What complete docker command do you run to launch the container (omitting sensitive values)?

docker run -it --rm -p 8888:8888 -e JUPYTER_LAB_ENABLE=yes -v "$PWD:/home/jovyan/mount" jupyter/scipy-notebook:03b897d05f16

What steps do you take once the container is running to reproduce the issue?

No additional steps

What do you expect to happen?

Jupyter should provide a URL that starts with: http://localhost:8888/ and contains one token.

What actually happens?

Jupyter provides a URL that starts with: http://3a2d76216bb6:8888/ and that contains two tokens:

I suspect this behavior may have been caused by #655 which bumped the notebook version to 5.5.

Closing as duplicate of #642. In general: The URL has never been valid because the container doesn't know the external port or ip. It happened to be right if you did the following:

• run docker locally (no docker-machine, etc.)
• forward the same port (8888:8888), never map different ports

Unfortunately, it's impossible for the container to know if either of these is the case, so the only reliable information that should be copied is the ?token=... part of the URL when the notebook is run in a container.
