在 docker 上验证 Jupyter notebook

Question

I am trying to install jupyter notebook docker container on my Mac laptop. With the following options

docker run -dit --rm -p 8888:8888 gcr.io/tensorflow/tensorflow

The container starts up and I can assess it on http://[cointainer-IP]:8888 as expected.

However it takes me to an authentication screen and asks for a token. How do i get the token, which log should I look for in the docker container

Answer 1

The stdout of the container will give you a special URL that has a token for you to login with. You can either run in the foreground (without -d ) or just checking the current container logs with docker logs <container_id> . There, you should see output like the following:

[I 16:57:05.859 NotebookApp] Writing notebook server cookie secret to /root/.local/share/jupyter/runtime/notebook_cookie_secret
[W 16:57:05.871 NotebookApp] WARNING: The notebook server is listening on all IP addresses and not using encryption. This is not recommended.
[I 16:57:05.877 NotebookApp] Serving notebooks from local directory: /notebooks
[I 16:57:05.877 NotebookApp] 0 active kernels 
[I 16:57:05.877 NotebookApp] The Jupyter Notebook is running at: http://[all ip addresses on your system]:8888/?token=42685cc246e6571c0f16417327fbf4c398061125c00edea5
[I 16:57:05.877 NotebookApp] Use Control-C to stop this server and shut down all kernels (twice to skip confirmation).
[C 16:57:05.878 NotebookApp] 

    Copy/paste this URL into your browser when you connect for the first time,
    to login with a token:
        http://localhost:8888/?token=42685cc246e6571c0f16417327fbf4c398061125c00edea5

Answer 2

You can also disable the token or add a customised token with the --NotebookApp.token='' parameter of the start-notebook.sh script. Coping the token from the Terminal often causes errors and is uncomfortable.

Disable token

Easily as follows:

docker run -d -p 8888:8888 jupyter/pyspark-notebook start-notebook.sh --NotebookApp.token=''

Customised Token

However, this is not recommended and you have the option to define an easy password:

docker run -d -p 8888:8888 jupyter/pyspark-notebook start-notebook.sh --NotebookApp.token='MY_EASY_PASSWORD'

Answer 3

I have written the following code for myself to automatically open a browser and enter authentication:

docker exec -it <docker container name> bash -c 'jupyter notebook list' | grep http | cut -f1 -d ' ' | xargs xdg-open

Works on Ubuntu 18.04

Answer 4

感谢您的提示，我只是使用命令docker logs <name of the container>找到了我的令牌

Answer 5

Run the following commands and copy the container ID number:

docker ps -a

docker logs <containerid>

From the log records, look for "To access the server .." like this:

http://127.0.0.1:8888/lab?token=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

Answer 6

Just in case someone else is in my situation: the only way I could solve this (thanks to a comment by @user3780173 in the accepted answer) was to close another instance of jupyter that I had running in my host machine. Only then I could open the notebook within docker. Before that, I entered the token produced by docker but always got "invalid credentials".
