From c5f0a5d788dafd94ea609b82d94cd089b30a7073 Mon Sep 17 00:00:00 2001 From: Valentin Rothberg Date: Wed, 27 Oct 2021 17:30:37 +0200 Subject: volumes: be more tolerant and fix infinite loop Make Podman more tolerant when parsing image volumes during container creation and further fix an infinite loop when checking them. Consider `VOLUME ['/etc/foo', '/etc/bar']` in a Containerfile. While it looks correct to the human eye, the single quotes are wrong and yield the two volumes to be `[/etc/foo,` and `/etc/bar]` in Podman and Docker. When running the container, it'll create a directory `bar]` in `/etc` and a directory `[` in `/` with two subdirectories `etc/foo,`. This behavior is surprising to me but how Docker behaves. We may improve on that in the future. Note that the correct way to syntax for volumes in a Containerfile is `VOLUME /A /B /C` or `VOLUME ["/A", "/B", "/C"]`; single quotes are not supported. This change restores this behavior without breaking container creation or ending up in an infinite loop.
