Hostinger Coolify VPS Template (Ubuntu 24.04)

Hostinger’s “Ubuntu 24.04 with Coolify” template ships with Coolify preinstalled.

Quick Checklist (Operator)​

  • Access Coolify UI at port 3000 on your VPS IP.
  • Finish first‑time admin + localhost onboarding.
  • Create a project, then add an app/database as a resource.
  • Lock down firewall, then later add domain + SSL.

1) Prerequisites (Hostinger)​

Note: Port defaults can vary across Coolify installs (commonly 8000 for generic installs), but the Hostinger template guide references 3000. If :3000 doesn’t load, confirm the port shown in your Hostinger panel or Coolify’s installation docs.

2) Accessing Coolify (first time)​

  1. Open: http://<YOUR_VPS_IP>:3000
  2. First access: create the admin account (email + password).
  3. Complete the onboarding wizard.

3) Onboarding: localhost vs remote​

When asked “Where to deploy?”, choose localhost if this is your only Coolify server and you want apps to run on the same VPS.

4) Create a project + add resources​

  1. Coolify dashboard → Projects → + Add (create a project, e.g. my-site-prod).
  2. Open the Production environment.
  3. Click + Add New Resource and pick:
    • Application (from Git repo, Docker image, etc.)
    • Database (PostgreSQL, MySQL, Redis, …)
    • Other services
  4. Deploy once and confirm logs look healthy.

5) Firewall + security (do this early)​

Close all doors, then open only what’s required:

  • Allow at minimum (typical):
    • 22/tcp (SSH; ideally restrict by source IP later)
    • 80/tcp (HTTP)
    • 443/tcp (HTTPS)
    • Coolify UI port: 3000/tcp (while configuring; later restrict)

If you use ufw on the VPS, mirror the same allow rules and then enable it.

6) Domains + SSL (after the app works)​

  1. In Coolify, set a Domain on the resource (e.g. app.example.com).
  2. Point DNS A record → your VPS public IP.
  3. Enable SSL/HTTPS in Coolify (Let’s Encrypt via the reverse proxy).

In Coolify:

  1. Project → Add Resource → Docker Compose
  2. Repo: ariffazil/arifOS
  3. Compose path: deployment/docker-compose.vps.yml
  4. Deploy

If deploy fails with network not found, create the external network once on the VPS:

docker network create coolify

Attach domain + HTTPS (arifOS)​

  • Resource → Domains → add arifosmcp.arif-fazil.com (or your subdomain)
  • Enable HTTPS / Let’s Encrypt (Coolify-managed)

Verify arifOS endpoints​

curl -i https://arifosmcp.arif-fazil.com/health
curl -N -H "Accept: text/event-stream" https://arifosmcp.arif-fazil.com/sse
curl -sS https://arifosmcp.arif-fazil.com/mcp \
  -H "Content-Type: application/json" \
  --data '{"jsonrpc":"2.0","id":1,"method":"tools/list","params":{}}'
