From cc49146332e279644f1357c6a5e209927bd73471 Mon Sep 17 00:00:00 2001 From: chesedo Date: Wed, 22 Jun 2022 16:52:18 +0200 Subject: Docker compat returning unknown "initialized" for `status.status` Some background for this PR is in discussion #14641. In short, ever so often a container inspect will return a `status.status` of `initialized` from the Docker compat socket. From the discussion I found these lines which tries to fix a "configured" status to "created". https://github.com/containers/podman/blob/c936d1e61154b6826e9d8df46e9660aba6c86cfe/pkg/api/handlers/compat/containers.go#L291-L294 However, commit 141de8686289 (Revamp Libpod state strings for Docker compat) removed the "configured" return value from the `String()` method called on line 291 above. Thus, making the `if` check redundant as it will never hit. But the same commit also introduces a return for "initialized" which this `if` should probably have been adapted for.
