From 93a3a398f759d1b92d639006ba6e513647386474 Mon Sep 17 00:00:00 2001 From: Tom Wieczorek Date: Tue, 19 Dec 2023 11:18:10 +0100 Subject: [PATCH 01/20] Use private cgroup namespaces for cgroup v2 Using the host's cgroup namespace along with a writable mount of the entire cgroup fs messes with container isolation quite a bit. The main purpose of this is to get a writable mount of the cgroup fs inside containers, so that init systems are able to set up their own cgroups accordingly. Use a different approach to achieve the same effect: Use a private cgroup namespace. Privileged containers will automatically have write access. A read-write mount is only performed when running non-privileged containers.
