Here is my docker-compose.yml

This looks good to me. I suspect the problem is not with the compose file itself, but in the tool you're invoking - something must be wrong with docker-compose. Try using
docker compose up -dinstead ofdocker-compose up -d(requires Docker v20.10.13+).Posting output of
docker-compose version,docker versionanddocker compose versionmay shine some light on this.Jesus man that was it. docker compose up -d solved it. Thank you so much
This means your
docker-composeis very outdated or even broken.To give you some context, originally Docker Compose was a separate project. It's a separate program called
docker-compose. It evolved for quite a while, and was eventually rewritten and included as a part of Docker itself, becaming a sub-command (docker compose).Just uninstall the old Compose (so it won't cause you any issues) and keep only Docker.
Alright now im getting
There was an error on the server. Try refreshing your browser. If that doesn't work, come back at a later time. If the problem persists, you can seek help in the Lemmy support community or Lemmy Matrix room.
but thats progress
This means Lemmy container is up and running, but there is some error on the backend that prevents it from functioning correctly. A pretty wild guess, but it's probably something with the database.
docker compose logsmay tell a bit more about what's going on. Check out this page https://join-lemmy.org/docs/administration/troubleshooting.html (just remember to replacedocker-composewithdocker compose- again, I specifically recommend to uninstalldocker-composeso it won't accidentally mess things up).If it's not something obvious, one thing you may try is tear everything down (
docker compose down -v), changelemmy:latesttolemmy:0.18.1in your Compose file, and try starting again. This will use explicit version number and it may help if thelatesttag is not something we expect it to be. E.g. I had issues spinning up clean 0.17.4 - it had a bug in DB migrations that was supposed to be fixed in 0.18.Yeah I figured some port was not enabled
where did you install Docker from? is it the docker repo or somewhere else?
Edit: check this out - https://docs.docker.com/engine/install/centos/
Yeah its from here
has docker got version locked in yum?
