Coolify's one-line install script is great — until it isn't. Right now it officially supports Ubuntu 20.04, 22.04, and 24.04 LTS. If you're running anything newer (Ubuntu's already on 26.04 LTS), the script won't work and you're left doing it manually. This is that manual walkthrough — set up in the order that fits a security-first VPS workflow rather than the order Coolify's own docs use. If you've been following along with the Ansible playbooks from earlier in this series, this picks up right where that left off. Minimum Hardware Requirements CPU: 2 cores Memory: 2 GB RAM Storage: 30 GB free Coolify can technically run below this, but it's not recommended. Prerequisites Before touching Coolify itself, you'll need: SSH access to your VPS CURL installed Docker Engine installed If you're reconnecting to a server you've rebuilt or re-provisioned, clear the old fingerprint first: ssh-keygen -f '/home/your-path/.ssh/known_hosts' -R 'your-vps-ip' Installing SSH If you followed the earlier videos in this series, OpenSSH is already installed. If not: sudo apt update && sudo apt install -y openssh-server Confirm it's running and check which port it's listening on (you should have already changed this from the default 22 — see the VPS security video): sudo systemctl status ssh sudo ss -tulpn | grep ssh Installing CURL sudo apt update && sudo apt install -y curl curl --version curl and ca-certificates also get installed as part of the apt-update Ansible playbook below, so this may already be handled. Running the First Ansible Playbook Connect Ansible to the VPS: ANSIBLE_HOST_KEY_CHECKING = FALSE ansible -i ./inventory/hosts vpsDemo -m ping --user root --ask-pass Then run the update playbook: ansible-playbook ./playbooks/apt-update.yml --user root -e "ansible_port=22" --ask-pass --ask-become-pass -i ./inventory/hosts If you haven't set up the Ansible inventory and playbooks from the earlier videos, do that first — this guide assumes they're already in place.
