What is pip's `--no-cache-dir` good for?

Question

I\'ve recently seen the --no-cache-dir being used in a Docker file. I\'ve never seen that flag before and the help is not explaining it:

 --no-cache         


        

Answer 1

Reduce your docker image size if you're having python dependencies in your DockerFile, as your private registries/artifactories or your deployment servcies may have size limitation.
