Description
Cleaning up the apt cache and removing /var/lib/apt/lists helps keep the image size down. Since the RUN statement starts with apt-get update, the package cache will always be refreshed prior to apt-get install.
You can read more about this here.
Note: Clean up must be performed in the same RUN step, otherwise it will not affect image size.
Bad Practice
RUN apt-get update && apt-get install -y python
Recommended
RUN apt-get update && apt-get install -y python \
&& apt-get clean \
&& rm -rf /var/lib/apt/lists/*
Exceptions
The official Debian and Ubuntu images are configured to automatically run apt clean, so explicitly invoking apt clean is not necessary there.
