Same here! Been self hosting on hetzner for about a year now, and support the OSS project for $10/month. Love how it can auto-deploy new git commits, deploy Postgres or any database to the same or separate servers, and you can cram as many apps or docker containers onto a single VPS or move them to a separate server when you need to.

Finally, little utilities like snapdrop or mosquitto are a button click away. Strongly recommended - it’s liberating! I don’t need to re-learn every PaaS vendor’s system - my PaaS comes with me. And a junior can be onboarded to this UI way easier than dokku or kamal IMO.

Another commenter mentioned that zero downtime deployments are not possible, isn't this a loss in your opinion, or did you find a way to do it using Coolify?

They were mistaken or maybe referring to an older version, because I definitively use rolling zero downtime updates from commits

For true zero downtime, the connections have to be slowly drained, i.e. two all instances may exist at the same time. Does coolify support that?

Coolify does support zero downtime deployments, but the documentation isn't live yet: https://github.com/coollabsio/documentation-coolify/blob/640...

It uses docker stop once the new container is healthy with a 30 second timeout, which I believe lets existing connections drain out.

"Move them to a separate server" - is that easy to do using Coolify?

Yes, you can move or clone to a separate server with a single click. Only volumes are not currently supported when doing this.

How? I can't find it in the docs.

Me neither. I found this https://github.com/Geczy/coolify-migration but if there's a native way to do it that would be great.

Full instance migration is in development but not yet released.

I understand you think it is obvious and no docs are required, but it is a bit ambiguous ”you can move or clone to a separate server with a single click” and ”Full instance migration is in development but not yet released.”

Just use the Clone button on the Resources page or on the Resource Operations tab of an application - the functions are very self-explanatory, so there is no documentation yet.
