From ad27532b6c9c657c7aecaca4bcccb5baa6576839 Mon Sep 17 00:00:00 2001 From: Daniel J Walsh Date: Tue, 5 May 2020 10:56:40 -0400 Subject: Eliminate race condition on podman info There is a potential of a race condition where a container is removed while podman is looking up information on the total containers. This can cause podman info to fail with an error "no such container". This change ignores the failure.
