Just read the other day here that Nextcloud runs much much better with PostgreSQL. Migrating to that (or the all in one installation) is my next big project.

Yes way faster, I switched a long time ago. If you want more extra speed add redis cache via unix sockets ☝🏻
Looks like I’ve got a project for next weekend
Interesting. Do you remember where you read this?
The process seems simple enough. I'm on the nextcloud:stable docker image, so adding a postgres container is really easy, but it's a scary task...
Okay, did the migration just now. Everything seems a little more responsive, but I wouldn't call it way faster.
Either way, it wasn't very scary at all. For anybody coming after me:
- add postgres container to compose file like so. I named mine "postgres", added a "postgres" volume, and added it to depends_on for app and cron
- run migration command from nextcloud app container like any other occ command and check admin settings/system for db state:
./occ db:convert-type --password $POSTGRES_PASSWORD --all-apps pgsql $POSTGRES_USER postgres $POSTGRES_DB - remove old "db" container and volume and all references to it from compose file and run
docker compose up -d --remove-orphans
Thank you for this. I really dislike MySQL/MariaDB and favor SQLite whenever possible, or PostgreSQL otherwise. The DB migration of my Nextcloud instance was high in my to-do list, and your instructions saved me research time.
Here's a cool article I found on Nextcloud performance improvements, and connecting Redis over Unix sockets gave me a more substantial performance improvement than migrating to Postgres. Very happy I fell down this rabbit hole today.
To note if you're following the tutorial in the link above, and for people using the nextcloud:stable container together with the recommended cron container:
- the redis configuration (host, port, password, ...) need to be set in
config/config.php, as well asconfig/redis.config.php - the cron container needs to receive the same
/etc/localtimeand/etc/timezonevolumes the app container did, as well as thevolumes_from: tmp
Thank you for the link and the Redis pointers. I should double check that my Nextcloud setup is using Redis, it might well be misconfigured.
If you do end up using postgresql, over time the database could end up getting fragmented and that can lead to increased latency, so routine pg_repacks imo are a worthwhile thing to schedule.
Well, another guy responded before you, so that would be the last time I heard it.
It was probably on one of the posts in this community.
