It’s mostly just preference. If you are already familiar with MySQL or Postgres, use what you know. If you just want simple and lightweight, use it with SQLite (no external database).

docker w/ postgres, but really up to you. Either would be fine.

If you design an application, choosing database would be a big deal, but since you are the user, you can choose whatever you want. My go to is postgre though.

thanks I will go for postgres database because of what I have been advised and additionally because I have been told that soon n8n will remove mysql/mariadb support.

Cloudron (free tier - 2 apps). Get a server, install Cloudron, install n8n from the app store. Done.

Please, I’m struggling with the docker-compose with postgres to get my n8n up and running… so just copy the docker-compose from the doc and made changes for my needs, could you tell me if im doin it rigth? or should I change something?

i want all data in: /docker/n8n/ so

root@13-n8n-RL23-WG /docker/n8n# nano .env

POSTGRES_USER=user-root

POSTGRES_PASSWORD=password-root

POSTGRES_DB=n8n

POSTGRES_NON_ROOT_USER=user-nonroot

POSTGRES_NON_ROOT_PASSWORD=password-nonroot

I wouldn’t know if someone can help me.

I have this has my Portainer Stack and all the variables configuration in the environment variables but while container works fine when first access, it reset when I edit the container or update and I have to create a new login.

I discovered recently that while other containers works fine, the worker container wouldn’t.

I’m new to docker and container and would appreciate help
