From 9d3667c2f025e1e36f3fdbd7348e0e14d00e336d Mon Sep 17 00:00:00 2001 From: Valentin Rothberg Date: Thu, 16 Jan 2020 15:46:39 +0100 Subject: systemdgen: add --ignore flag to generic services The --ignore flag lets Podman ignore errors when a specified container does not exist (anymore). That's a nice addition to generic services generated via the --new flag. Those services create new containers and can hence allows user to manually remove a container; may it only be by accident. The important part of using the --ignore flag is that Podman will exit 0 which plays nicer with most restart policies; a non-zero exit may yield systemd to restart the entire service which is arguably wrong if the user manually deletes the container. If desired, users can still alter the generated files.
