using "--no-cache-dir" flag in pip install ,make sure downloaded packages by pip don't cached on system . This is a best practice which make sure to fetch from repo instead of using local cached one . Further , in case of Docker Containers , by restricting 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.

changed the title
PIP_NO_CACHE_DIR=yes for pip in Dockerfiles ENV, to save space--no-cache-dir flag to pip in dockerfiles, to save space
yes , got it , this is because this feature is implemented in PIP v20 later but initially the system contain old version of PIP , which make it crash because it automatically loaded from Environment Variable . i.e. why i switched whole system to traditional "--no-cache-dir" flag to ignore pip caches in Docker Images to reduce download size and time |
