From 6ca721cccd98bf9936b33d690b28a52cd4213a18 Mon Sep 17 00:00:00 2001 From: Daniel J Walsh Date: Fri, 21 May 2021 08:00:47 -0400 Subject: Drop container does not exist on removal to debugf We have race conditions where a container can be removed by two different processes when running podman --remove rm. It can be cleaned up in the API or by the conmon executing podman container cleanup. When we fail to remove a container that does not exists we should not be printing errors or warnings, we should just debug the fact. [NO TESTS NEEDED] Since this is a race condition it is difficult to test.
