Publishing image fails on an LXD cluster member #47
Description
Overview of the Issue
Publishing an image fails on an LXD cluster member, because the container might not run on the same node where packer is running. The images are replicated between cluster nodes but there's an obvious lag. Packer does not wait for the image to be replicated before checking if it was successfully published.
Another possible approach would be to add an "lxc launch" option "--target" where you can specify where to run the container, in the same node where you are running packer.
Reproduction Steps
Just build any image on an LXD cluster member and wait for it to be built and published
