Issue descriptionIssue description

When building a Docker image, you see this error during testing:

TestsFailure:It is not possible to start the docker container for testing.
Make sure that the requirements from the documentation are satisfied.

SolutionSolution

Correctness tests ensure that the project operates properly on the Docker image. Possible errors:

  1. The image is intended to launch a service (for example, a web application) rather than Jupyter.
  2. The error occurs because there is no jupyter user in Docker. You can install it using this command:
RUN useradd -ms /bin/bash --uid 1000 jupyter

If the issue persistsIf the issue persists

If the above actions didn't help, create a request for support.

When creating a request, attach your Dockerfile for analysis.
