Ports already used

• Symptoms:

  • Bind for 0.0.0.0:8888 failed: port is already allocated.
  • listen tcp 0.0.0.0:8888: bind: address already in use.

• Solution:

  Another software is already using the port 8888 on your computer. This might be another docker container, please run docker ps to see if you have any container using 0.0.0.0:8888->8888/tcp in the PORTS column. In this case, you can decide to stop it, and then try again.

  Otherwise, you can decide to bind jupyter's port 8888 inside the container to another port on your computer, eg. 8889: docker run --rm -p 7000:7000 -p 8889:8888 -v summer-school:/home/student -it memoryofmotion/summer-school. Then you will have to adapt the url given by jupyter with this port, eg. http://127.0.0.1:8889/?token=2fa…

  The same solution can be used for meshcat port 7000. In that case, to open meshcat, you will have to use eg. http://127.0.0.1:7001/static/
