And to anyone else who comes looking, You can simply add the docker tag to the old mealie image. The official mealie docker is
https://hub.docker.com/layers/hkotel/mealie/v0.5.6/images/sha256-14cfa36c38bd392a07bd95779c094b1abfe3e0a46ef5b846fec635ec45cea9d6?context=explore
which is 0.5.6. The old mealie template was abandoned, which is why I took over this one. Going forward we use the official Mealie everything, so this won't happen again. V1 is awesome!
