Testing done:

• unit tests
• container testing in feat: support codeartifact for installing requirements.txt packages #130 (comment)

I've been using the codeartifact-related code for a few months already. I was not able to add any related integration tests as such tests would require access to a fixed codeartifact repo, and for the container to have access to AWS credentials.

I'm asking for guidance if any such integ tests would be needed here.

Additionally, is anything required in README to mention this CodeArtifact support?

I did some testing by modifying test/container/dummy/Dockerfile to

+COPY dummy/requirements.txt /opt/ml/models/code/requirements.txt
+
 ENTRYPOINT ["python", "/usr/local/bin/dockerd-entrypoint.py"]
 CMD ["serve"]

where requirements.txt is a copy of https://github.com/aws/sagemaker-training-toolkit/blob/master/test/container/dummy/requirements.txt

I then went ahead and started the container - once without setting the CA_* env variables and once with

I think it makes more sense to add a new feature which allow user to run plugin module at model server start time than add more specialized function here.
