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 https://medium.com/sciforce/strategies-of-docker-images-optimization-2ca9cc5719b6 Change-Id: Ibea3f30e4a67c21e3b0e2a1ee6090131ca54194b Signed-off-by: Pratik Raj <rajpratik71@gmail.com>
