From afa823e4e71c5bf7a00f048c3c7b86746877dbf2 Mon Sep 17 00:00:00 2001 From: Daniel J Walsh Date: Wed, 5 Aug 2020 16:28:47 -0400 Subject: Fix handling of working dir Buildah and podman build can create images without a working dir. FROM fedora WORKDIR /test If you build this image with caching twice, the second time the image will not have a working dir. Similarly if you execute podman run --workdir /foobar fedora It blows up since the workingdir is not created automatically. Finally there was duplicated code for getting the workingdir out of an image, that this PR removes.
