From 309e87ce8d9c333671ad68b9851544803bde554c Mon Sep 17 00:00:00 2001 From: Pratik raj Date: Wed, 30 Dec 2020 18:54:43 +0530 Subject: [docker] use `--no-cache-dir` flag to `pip` in dockerfiles to save space 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.
