Authenticating Jupyter Notebook inside Docker keeps resulting in invalid token
You probably did not forward the port from the container to the host when running the container:docker run -it -p 8888:8888 tag --port=8888
But that should give you a ERR_CONNECTION_REFUSED unless you already have a jupyter running locally on 8888, which of course does not recognize the token from docker instance. Try to run the container with port forwarding and make sure it's a different port than any local instances.
