From 11f65c6c1d3bfd6a12f8e71d778d46d635010449 Mon Sep 17 00:00:00 2001 From: Michal Arbet Date: Tue, 15 Feb 2022 13:50:59 +0100 Subject: Add mechanism for patching files in containers This patch adds a way to patch files in a Docker image built by Kolla. This is very useful for several reasons, specifically: - Custom modifications - The stable branch of some library has a fix but no pip package has been released - Eliminates the need to package your own pip packages - Eliminates the need to invent your own versioning to prevent upstream versioning - Eliminates the need to manage a pip server - In other words, it eliminates the need to get a wheel into the image and install it manually using any method not previously mentioned It is also highly desirable because, although Kolla can replace the source for a service with a custom URL for a tarball or its own Git repo, it cannot do this for dependencies pulled from pip. I would also like to point out that this is a feature with its own code path and works only if the user "inserts" a patch into the folder patches/docker-image/something.patch and creates an analogous series file for patch source code. Simply said, this code will never interfere with the upstream build process since this feature is not intended for use in upstream. It is rather meant for downstream users who know what they are doing. Now they just have an option to patch their images. Everything works on all layers of the Docker image and stores a report of applied patches which can then be seen in /etc. This mechanism is similar as debian patch quilt.
