Coolify Self-Hosting: A Step-by-Step Deployment guide

Prerequisites and Server Setup

Before deploying containers, ensure your server environment is ready. These prerequisites guarantee compatibility, predictable performance, and secure access for your Coolify stack.

Category	Specification	Notes
Host OS	Ubuntu 22.04 LTS	A stable base with excellent Docker and tooling support.
RAM	Minimum 4 GB	8 GB is recommended for running multiple applications or handling heavier workloads.
Disk space	At least 20 GB	Sufficient for the base stack and logs; add more for application data and backups.
Network & Admin	Static public IP, registered domain, SSH-enabled admin user with sudo	Ensures reliable remote access and domain name resolution.
Firewall & DNS	Open ports 80 (HTTP) and 443 (HTTPS); DNS resolves domain to server	Enables web traffic and correct domain name resolution.

Implementation Quick-Start (practical Steps):

• Install Ubuntu 22.04 LTS as your host OS to maximize compatibility with Docker and other essential tools.
• Allocate sufficient resources: aim for at least 4 GB of RAM; 8 GB or more is advisable if you plan to run multiple applications or handle intensive workloads.
• Ensure ample disk space: a minimum of 20 GB is needed for the base stack and logs. Plan for additional space for application data and backups.
• Configure networking and access: set up a static public IP address, register a domain name, and create an SSH-enabled administrator user with sudo privileges.
• Set up your firewall and DNS: open ports 80 (for HTTP) and 443 (for HTTPS). Configure your DNS records so that your domain name resolves to your server’s IP address.

Installing Docker and Docker Compose

Docker simplifies the process of running applications in isolated, repeatable environments. Here’s a concise guide to installing Docker and Docker Compose, enabling the Docker daemon, and verifying the installation.

1. Install Docker and related tooling: Update your package index and install the core components.

   sudo apt update
   sudo apt install -y docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

2. Enable and start the Docker daemon:

   sudo systemctl enable docker
   sudo systemctl start docker

3. Verify installations: Check the installed versions.

   Docker version:

   docker --version

   Docker Compose version:

   docker compose version

4. Ubuntu 22.04+ Note: If you are using Ubuntu 22.04 (Jammy Jellyfish) or a newer version, ensure that the official Docker repository is configured before installation. This ensures you obtain the latest, officially supported packages.

Cloning Coolify and Deploying the Stack

In today’s fast-paced tech landscape, speed and clarity are crucial. Cloning Coolify and deploying its stack is a swift, repeatable process that allows you to quickly set up a powerful and secure user interface. Follow this straightforward path to get Coolify live.

Clone the official Coolify repository

git clone https://github.com/coollabsio/coolify.git

Enter the repository and deploy the stack

Navigate into the project directory, fetch the latest Docker images, and start the services in detached mode:

cd coolify
docker compose pull
docker compose up -d

Check deployment status

Verify that all services have started correctly:

docker compose ps

Access the UI

Open your domain name or server IP address in a web browser. After the initial setup, remember to enable TLS to secure all traffic to the UI and API.

Initial Coolify Configuration

First impressions count. In just a few minutes, you can transition from initial setup to a secure, collaborative environment for deploying applications. Here’s an efficient way to get Coolify operational.

• Open the Coolify UI: Navigate to https://your-domain in your browser. This is your central hub for managing your space, inviting team members, and connecting your code repositories.
• Create the admin account, organize teams/organizations, and connect a Git provider: Set up your administrator credentials, create teams or organizations as your team expands, and connect your preferred Git provider (e.g., GitHub, GitLab) to enable builds and deployments from your repositories.
• Configure environment and repository templates; set up the first runtime: Use the UI to define reusable environment and repository templates, ensuring new projects start with sensible defaults. Then, configure your first runtime (such as Node.js) to provide a ready-to-deploy baseline for your applications.
• Enable TLS/HTTPS: Add your domain within the Coolify UI and issue SSL certificates to enable secure HTTPS traffic. You can utilize Coolify’s integrated certificate provisioning (Let’s Encrypt) or provide your own certificates through an external process.

Tip: After completing these steps, you’ll be ready to deploy a sample application and validate your deployment workflow.

Deploying Your First App (Node.js Example)

Deploying a Node.js application with Coolify is a straightforward, visual process. From creating a new app to connecting your Git provider and selecting the Node.js runtime, you’ll be ready to deploy quickly. Here’s the fast track:

• Set up in Coolify: Navigate to New App in Coolify, select your Git provider (e.g., GitHub), choose the Node.js runtime.
• Build and start commands:
  • Build command: npm ci (or npm install)
  • Start command: npm start (or node index.js)
• Environment variables: Configure necessary environment variables (e.g., API keys, DATABASE_URL, or other secrets) to ensure your application runs securely.
• Deploy and monitor: Click Deploy and observe the build logs within the UI. For automatic updates, enable redeploy on Git push.

Edge Cases and Troubleshooting

When deployments encounter issues, approach troubleshooting methodically by identifying the weak link, resolving the problem, and restoring service swiftly. Here’s a practical guide to common trouble areas.

Common Issue: 502 Bad Gateway After Reverse Proxy Configuration

• Verify proxy configuration: Confirm upstream addresses, ports, and TLS termination settings are correct. Ensure the proxy correctly routes requests to the intended service and path.
• Check TLS certificates: Ensure certificates are valid and match the domain (no expired certificates or mismatched Common Name/Subject Alternative Names).
• Test upstream connectivity: Use a tool like curl from the proxy server to verify reachability to the upstream service.
• Restart services: After applying fixes, restart both the reverse proxy and the backend application to clear any stale connections.
• Inspect logs: If the 502 error persists, examine the proxy logs for details such as timeouts or upstream errors, and adjust timeout settings if necessary.

Container Issues

• Use docker compose logs -f to view live logs and docker ps -a to list all containers and their status.
• Identify failing containers and restart them using docker compose up -d.
• Check for unhealthy containers, ensure volumes are correctly mounted, and verify that network connections between services are intact.

DNS or TLS Problems

• Verify that your DNS A record correctly resolves to your server’s IP address. Use tools like dig or nslookup for confirmation.
• Ensure your TLS certificates are valid and properly configured; re-provision them if necessary (e.g., via ACME renewal).
• After making DNS or certificate changes, reload or restart affected services to apply the new configurations.

Resource Constraints

• Consider allocating more CPU or RAM to your host machine, or scale your deployment by adding more nodes if operating in a clustered environment.
• Monitor container and system resource metrics to identify bottlenecks (CPU, memory, disk I/O) and adjust resource allocation or capacity accordingly.

Deployments Fail at Build Time

• Review your build scripts for errors, verify that all dependencies are present and correctly installed.
• Ensure the build container has network access and appropriate permissions to reach necessary resources such as registries, dependencies, or proxies.
• Rerun the build after making corrections and confirm that the generated artifacts are available for subsequent pipeline steps.
