which is the best solution to selfhosted n8n?

hi folks i am starting to use n8n and i want to do some automations in my kommo crm and other things, but i have seen that there are several ways to install n8n in a self hosted way, so my question is for those who have n8n as self hosted services,

which would be the best way to install it?

- docker without database?
- docker with database and which database would be better postgress or mysql?
thanks

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

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).

- I will create a lxc conteiner in my proxmox just for him so my question would be... which one would be more secure that it will not have problems in the future? for example that it is slower or easier to be damaged or lose information or that it lacks some feature, do you know what I mean?

  Use SQLite. Easy to backup, no process taking up cpu/memory, no users to manage.

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.

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

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.

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'm new to docker and container and would appreciate help

This my docker-compose file
