@davidmehren many thanks for getting back.
Hmm, I tried to go through the steps of the upgrade docs for Docker, and got an error at the very first one
# docker-compose exec database createuser --superuser -Uhackmd postgres
createuser: could not connect to database postgres: FATAL: role "hackmd" does not exist
Also, call me thick, but I don’t see any upgrade instructions. There is a single sentence saying “you should be able to swap the docker image for ours” … but no actual instructions. Surely replacing the docker-compose.yml with the contents shown here Docker Image - HedgeDoc won’t work … i also have a separate postgres 11.5 docker as part of my codimd 1.4.1 docker deployment.
Are you saying only the two
image: lines should be replaced, one with postgresql 13 and the other with hedgehog? What about the postgres user commands above that failed?
