Pattern: Missing version pinning for apt-get install

Issue: -

Description

Version pinning forces the build to retrieve a particular version regardless of what’s in the cache. This technique can also reduce failures due to unanticipated changes in required packages.

Example of incorrect code:

RUN apt-get install python

Example of correct code:

RUN apt-get install python=2.7
