From 246fa098a96a14321da47d5df491ead7800b9c92 Mon Sep 17 00:00:00 2001 From: xiadanni Date: Fri, 19 Feb 2021 16:37:48 +0800 Subject: [PATCH] containerd: fix containerd-shim residual when kill containerd during starting container after shim process started, containerd will write shim socket address to address file, but if containerd is killed before write file, new containerd process could not get shim socket address, and will not kill it even if that shim could not work. so we write address file ahead of starting shim process.
