From 3a4be4b66ca22d87446c37218b300b8f31a84b92 Mon Sep 17 00:00:00 2001 From: Daniel J Walsh Date: Fri, 26 Apr 2019 10:51:59 -0400 Subject: Add --read-only-tmpfs options The --read-only-tmpfs option caused podman to mount tmpfs on /run, /tmp, /var/tmp if the container is running int read-only mode. The default is true, so you would need to execute a command like --read-only --read-only-tmpfs=false to turn off this behaviour.
