Dokku-shoreman: unable to find image /dokku locally

Trying to deploy a Ruby on Rails app with dokku + docker. I accidentally deleted all containers and images on my server and now, I can’t use dokku-shoreman to run a worker like I was before. When I try to run the post-release executable from the shoreman plugin, I get an error “unable to find image /dokku locally”. But when I type docker images, I see dokku/MY_APP as an image.

What am I missing here? (I tried re-installing dokku-shoreman and re-deploying as well, but neither fixed the problem).

I’ve not run into this yet, but you might take a look at the Dokku issues [1] or the dokku-shoreman issues [2] to see if anybody else has. The shoreman plugin was not written by the Dokku maintainers, but it’s possible the community in the freenode irc channel #dokku can help. Lastly, although reinstalling the plugin doesn’t help, it could help to reinstall the entire Dokku system.
