From 4a863df57a357823ff6ecd7b883a87781034f499 Mon Sep 17 00:00:00 2001 From: Sebastiaan van Stijn Date: Wed, 12 Apr 2023 18:12:08 +0200 Subject: [PATCH] docs/reference: remove mention of DOCKER_NOWARN_KERNEL_VERSION Support for this environment variable was removed in docker 23.0 in https://github.com/moby/moby/commit/1240f8b41d34abe9252b882bddd42e140b62b83b From that patch: > All regular, non-EOL Linux distros now come with more recent kernels > out of the box. There may still be users trying to run on kernel 3.10 > or older (some embedded systems, e.g.), but those should be a rare > exception, which we don't have to take into account. > > This patch removes the kernel version check on Linux, and the corresponding > DOCKER_NOWARN_KERNEL_VERSION environment that was there to skip this > check.
