From 830f3a4462953b3698a21031db3964d0f0ae63b3 Mon Sep 17 00:00:00 2001 From: Brent Baude Date: Tue, 14 Apr 2020 09:02:28 -0500 Subject: v2podman ps revert structure changes reverting name changes to the listcontainer structure because it negatively impacted the direct consumption of the restful API. instead we now use a local structure in the CLI to modify the output as needed.
