Subject: optimize size and time using "--no-cache-dir"
X-Git-Url: https://gerrit.onap.org/r/gitweb?a=commitdiff_plain;h=389393eb86e4325f3fcc7cd6b4135be2881b0baa;hp=389393eb86e4325f3fcc7cd6b4135be2881b0baa;p=appc.git

optimize size and time using "--no-cache-dir"

Using "--no-cache-dir" flag in pip install ,make sure dowloaded packages
by pip don't cached on system . This is a best practise which make sure
to fetch ftom repo instead of using local cached one . Further , in case
of Docker Containers , by restricing caching , we can reduce image size.
In term of stats , it depends upon the number of python packages
multiplied by their respective size . e.g for heavy packages with a lot
of dependencies it reduce a lot by don't caching pip packages.

Further , more detail information can be found at
