Applications

Application could be any type of web application. It could be a static site, a NodeJS application, a PHP application, etc.

For complex applications, you can use Docker Compose based deployments or the one-click services.

Examples

General Configuration

Commands

You can overwrite the default commands by setting a custom value on the UI.

  • Build
  • Install
  • Start

Base Directory

It is useful for monorepos. You can set the base directory for all the commands that will be executed by Coolify.

Public Directory

If you are building a static site, it is important to set the public directory, so the builder will know which directory to serve.

Port Exposes

Port exposes are required for Docker Engine to know which ports to expose. The first port will be the default port for health checks.

Examples:

If you have a NodeJS application that listens on port 3000, you can set it like this: 3000. If you have a PHP-FPM application that listens on port 9000, you can set it like this: 9000. If you have a Nginx server that listens on port 80, you can set it like this: 80.

Port Mappings

If you would like to map a port to the host system (server), you can do it here like this: 8080:80.

This will map the port 8080 on the host system to the port 80 inside the container.

Advanced

Static Site (Is it a static site?)

This feature is only available for Nixpacks buildpacks.

If you need to serve a static site (SPA, HTML, etc), you can set this to true. It will be served by Nginx. Disabled by default.

Force HTTPS

If you would like to force HTTPS, so no HTTP connections allowed, you can set this to true. Enabled by default.

Auto Deploy

This feature is only available for GitHub App based repositories.

If you would like to deploy automatically when a new commit is pushed to the repository, you can set this to true. Enabled by default.

Preview Deployments

Preview deployments are a great way to test your application before merging it into the main branch. Imagine it like a staging environment.

URL Template

You can setup your preview URL with a custom template. Default is {{pr_id}}.{{domain}}.

This means that if you open a Pull Request with the ID 123, and you resource domain is example.com the preview URL will be 123.example.com.

Automated Preview Deployments

This feature is only available for GitHub App based repositories.

If you would like to deploy a preview version of your application (based on a Pull Requests), you can set this to true. Disabled by default.

If set to true, all PR’s that are opened against the resource’s configured branch, will be deployed to a unique URL.

Manually Triggered Preview Deployments

You can manually deploy a Pull Request to a unique URL by clicking on the Deploy button on the Pull Request page.

Git Submodules

If you are using git submodules, you can set this to true. Enabled by default.

Git LFS

If you are using git lfs, you can set this to true. Enabled by default.

Persistent Storage

Health Checks

By default, all containers are checked for liveness.

Rollbacks

You can rollback to a previous version of your resource. At the moment, only local images are supported, so you can only rollback to a locally available docker image.

Resource Limits

By default, the container won’t have any resource limits. You can set the limits here. For more details, read the Docker documentation.

Deployment Types

There are several types of application deployments available.

  • Public Git Repository
  • Private Git Repository (GitHub App)
  • Private Git Repository (Deploy Key)
  • Based on a Dockerfile
  • Based on a Docker Compose
  • Based on a Docker Image

Build Packs

These are the supported build packs:

  • Nixpacks
  • Dockerfile
  • Docker Image
  • Docker Compose

Nixpacks

Coolify uses Nixpacks as build pack by default. Nixpacks detect what kind of application are you trying to deploy and builds it accordingly.

But if needed, you can customize it by adding a nixpacks.toml file to your repository or setting the right environment variables.

For example, if you are using a NodeJS application, you can set the NIXPACKS_NODE_VERSION to control the NodeJS version.

Dockerfile

Dockerfile based build packs are useful if you have a custom dockerfile inside your Git repository.

Custom Dockerfile Location

You can always set your custom dockerfile location. By default, it is set to /Dockerfile.

Docker Image

You can deploy any docker images from any Docker compatible repository. For example, you can deploy images from Docker Hub, GitHub Container Registry, etc.

Docker Compose

Docker Compose based deployments are useful for complex applications. You can define multiple services in a single docker-compose.yml file and deploy them together.
