If you are using Oracle Cloud free ARM server, you need to do a few extra steps to use it in Coolify, as a Coolify instance or just a remote server.

​
Normal user

Non-root user is in experimental mode and works with sudo.

  • Make sure the ssh key is added to the user’s ~/.ssh/authorized_keys file.
  • All configuration is set for sudo. Details here.

​
Setup Root User

By default, you can’t login as root user. You need to do the following steps to enable root user.

  1. Switch to root user sudo su -
  2. Edit /etc/ssh/sshd_config and change PermitRootLogin to without-password.
  3. Restart ssh service service sshd restart
  4. Add a public key to /root/.ssh/authorized_keys file which is also defined in your Coolify instance.

​
Firewall Rules

This is only required if you self-host Coolify on Oracle ARM server.

By default, Oracle ARM server has a firewall enabled and you need to allow some ports to use Coolify.
