From 4f427a89cbc0814c25dd4b562ddf4ff4e568a005 Mon Sep 17 00:00:00 2001 From: Paul Holzinger Date: Tue, 17 Nov 2020 16:43:17 +0100 Subject: Align the podman ps --filter behavior with docker All of our filters worked exclusive resulting in `--filter status=created --filter status=exited` to return nothing. In docker filters with the same key work inclusive with the only exception being `label` which is exclusive. Filters with different keys always work exclusive. This PR aims to match the docker behavior with podman.
