First time:
docker run -v /global/path/to/zk-adventures:/home/sage/zk-adventures --name sage -p 8888:8888 sagemath/sagemath:latest sage-jupyter
Check out URL of the logs to navigate to the sage notebook: http://127.0.0.1:8888/?token=some-random-token
If you already ran the above you can open it back with
docker start sage
To recover the URL you can use (you may need to wait a bit after the command above)
docker logs sage
