From 18300573f98883a4d6af09afe49a1e789e3a8f54 Mon Sep 17 00:00:00 2001 From: Matthew Heon Date: Mon, 22 Jun 2020 15:05:22 -0400 Subject: Set syslog for exit commands on log-level=debug We have a flag, --syslog, for telling logrus to log to syslog as well as to the terminal. Previously, this flag also set the exit command for containers to use `--syslog` (otherwise all output from exit commands is lost). I attempted to replicate this with Podman v2.0, but quickly ran into circular import hell (the flag is defined in cmd/podman, I needed it in cmd/podman/containers, cmd/podman imports cmd/podman/containers already, etc). Instead, let's just set the syslog flag automatically on `--log-level=debug` so we log exit commands automatically when debug-level logs are requested. This is consistent with Conmon and seems to make sense.
