What is the default password for Docker version TensorFlow?

  docker, question

The official version is installed on the Docker clientTensorFlowAfter startup, I need a password to enter jupyter interface, but I didn’t find any introduction about the default password in the document. do I need to do anything else first?

Startup log:
