Gateway restores fail on Ignition 8 when volume mounted about ignition-docker HOT 4 CLOSED

Great catch @ptrdlbrg. Unfortunately, my recent work to support third-party modules has driven me to suggest that folks target their named volume at /var/lib/ignition/data instead of the full /var/lib/ignition path. This is done so that when containers are upgraded from one version to the next, only the data is preserved and the modules from user-lib are still bound to the container and thus are changed out with new ones in the upgraded container image. I was able to reproduce your failure with a volume at /var/lib/ignition/data. I may try linking temp from /usr/local/share/ignition/temp to /var/lib/ignition/data/temp and see if that could get us going. I don’t like storing that temp data in with the user volume, but we may have little choice until the underlying issue is addressed.

I went ahead and mapped the temp directory into /var/lib/ignition/data/temp and was able to successfully restore without an error with a named volume bound to /var/lib/ignition/data (as is now the recommendation). The fix is in e55d119. I’ve triggered a build and Docker Hub should have the updated images. @ptrdlbrg, can you pull the latest and confirm that it is working for you?

Whether or not a user would include user-lib in their volume depends on their use case, so I like how you've structured it so you can include it or exclude it based on which directory you set your volume to. Your solution of putting temp inside of the data directory is a reasonable solution.

I agree that I would prefer to keep temp out of the volume, but unfortunately that doesn't seem to be an option right now.

I pulled the latest 8.0.2 and confirmed that restores now work as they should. Thanks for the quick response. Thank you for creating and maintaining these docker images. I really appreciate it!

I reported the underlying bug on the Ignition forum.
