No matter what type of server you have (localhost or remote), you need the following requirements.

  • Connectivity

    • SSH connectivity between Coolify and the server with SSH key authentication.

      Your public key should be added to root user’s ~/.ssh/authorized_keys. If you do not have an SSH Key, you can generate on through Coolify with a simple button or you can generate one manually.

  • Docker Engine (24+)

​
Types

  • Localhost: the server where Coolify is installed.
  • Remote Server: could be any remote linux server.

​
Localhost

To be able to manage the server where Coolify is running on, the docker container of Coolify should reach the host server through SSH.

You can use localhost as a server where all your resources are running, but it is not recommended as high server usage could prevent to use Coolify.

You can use our Cloud version, so you only need a server for your resources. You will get a few other things included with the cloud version, like free email notifications, s3 storage, etc based on your subscription plan.

​
Remote Server

You can connect any type of servers to Coolify. It could be a VPS, a Raspberry PI or a laptop running Linux.

If you don’t have a server or server provider yet, we prefer to use Hetzner.

You can use our referral link. It will helps us to keep the project alive.

​
Cloudflare Tunnels

You can also set to use Cloudflare Tunnels for your servers.

Coolify does not install cloudflared on your server, it needs to be done prior.

All it does is to add the right ProxyCommand (ProxyCommand <ip / hostname> access ssh --hostname %h) to all ssh connections.

​
Features

​
Disk Cleanup threshold

You can set a threshold in % for your / filesystem. If this percentage is reached, Coolify tries to cleanup a lot of unnecessary files from your server.

  • Unused Docker Images (docker image prune -af')
  • Unused Docker Build Images (docker builder prune -af)
  • Stopped Docker Containers deployed by Coolify (docker container prune -f --filter "label=coolify.managed=true")

​
Wildcard Domain

You can set a wildcard domain (example: http://example.com) to your server, so you can easily assign generated domains to all the resources connected to this server.

Example: Your application UUID is vgsco4o.

If you have the example set, you will get the following FQDN: http://vgsco4o.example.com

If you do not have any wildcard domain set, Coolify will generate a sslip.io domain, which is free & magical domain that you can use anywhere.

In this case, it will be: http://vgsco4o.127.0.0.1.sslip.io, where 127.0.0.1 is your server’s IP.

​
Proxy

  • Traefik: Automatically configure Traefik(v2) based on your deployed resources.
  • Custom/None: You will configure a proxy manually (only for advanced users).

Soon we will support Nginx & Caddy with fully automated configuration.

​
Traefik

Coolify uses Traefik proxy by default to create a reverse proxy for your resources.

Traefik only starts when you did not select any proxy for your server and you have a domain configured for a resource or your Coolify instance itself.

​
Dynamic Configuration

You can always add your own configuration to the proxy settings from Coolify’s UI (/server/<server_uuid>/proxy).
