I'm working on deploying a Docker container to ECR for a daily batch job, and I've mostly handled Python projects by running `pip install -r requirements.txt`. Now, I'm joining a team that uses AWS CodeArtifact, which they've used extensively for Node/JS projects by pulling npm packages from there. I'm wondering if there are any real advantages to using CodeArtifact for managing Python packages instead of just installing them manually every time in the Docker container.

Using CodeArtifact brings a bunch of perks! It centralizes your package management, helps with version control, enhances security, and even caches your dependencies. Plus, it can significantly reduce build times and keep your dependencies consistent across different environments. Integration with AWS is also a plus.
Think of CodeArtifact as your own private package repository. You control the packages and versions, which means you won't face the risk of important packages getting deleted like on PyPi. That said, if you're not creating custom Python modules, you might just consider building a custom Docker base image instead. Just keep in mind that CodeArtifact does require a 12-hour auth token, which can complicate things a bit in your pipeline.
One important benefit of using CodeArtifact is supply chain provenance. It ensures that everyone on the team deliberately adds and controls dependencies during the build process. This is crucial, especially after incidents like the left-pad debacle, where relying on public repositories can introduce significant risks.
And that's just the tip of the iceberg when it comes to potential issues!
