## 1. Setup Development Environment
Follow the steps below for your operating system:
<details>
<summary><strong>Windows</strong></summary>
1. Install `docker-ce`, Docker Desktop (or similar):
- Docker CE (recommended):
- Install Windows Subsystem for Linux v2 (WSL2) by following this guide: [Install WSL](https://learn.microsoft.com/en-us/windows/wsl/install?ref=coolify)
- After installing WSL2, install Docker CE for your Linux distribution by following this guide: [Install Docker Engine](https://docs.docker.com/engine/install/?ref=coolify)
- Make sure to choose the appropriate Linux distribution (e.g., Ubuntu) when following the Docker installation guide
- Install Docker Desktop (easier):
- Download and install [Docker Desktop for Windows](https://docs.docker.com/desktop/install/windows-install/?ref=coolify)
- Ensure WSL2 backend is enabled in Docker Desktop settings
2. Install Spin:
- Follow the instructions to install Spin on Windows from the [Spin documentation](https://serversideup.net/open-source/spin/docs/installation/install-windows#download-and-install-spin-into-wsl2?ref=coolify)
</details>
<details>
<summary><strong>MacOS</strong></summary>
1. Install Orbstack, Docker Desktop (or similar):

- Download and install [Orbstack](https://docs.orbstack.dev/quick-start#installation?ref=coolify)
- Docker Desktop:
- Download and install [Docker Desktop for Mac](https://docs.docker.com/desktop/install/mac-install/?ref=coolify)
2. Install Spin:
- Follow the instructions to install Spin on MacOS from the [Spin documentation](https://serversideup.net/open-source/spin/docs/installation/install-macos/#download-and-install-spin?ref=coolify)
</details>
<details>
<summary><strong>Linux</strong></summary>
1. Install Docker Engine, Docker Desktop (or similar):
- Docker Engine (recommended, as there is no VM overhead):
- Follow the official [Docker Engine installation guide](https://docs.docker.com/engine/install/?ref=coolify) for your Linux distribution

2. Install Spin:
- Follow the instructions to install Spin on Linux from the [Spin documentation](https://serversideup.net/open-source/spin/docs/installation/install-linux#configure-docker-permissions?ref=coolify)
</details>
## 2. Verify Installation (Optional)
After installing Docker (or Orbstack) and Spin, verify the installation:
1. Open a terminal or command prompt
2. Run the following commands:
```bash
docker --version
spin --version
```
You should see version information for both Docker and Spin.
## 3. Fork and Setup Local Repository
1. Fork the [Coolify](https://github.com/coollabsio/coolify) repository to your GitHub account.
2. Install a code editor on your machine (choose one):
| Editor | Platform | Download Link |
|--------|----------|---------------|
| Visual Studio Code (recommended free) | Windows/macOS/Linux | [Download](https://code.visualstudio.com/download?ref=coolify) |
| Cursor (recommended but paid) | Windows/macOS/Linux | [Download](https://www.cursor.com/?ref=coolify) |
| Zed (very fast) | macOS/Linux | [Download](https://zed.dev/download?ref=coolify) |
3. Clone the Coolify Repository from your fork to your local machine
- Use `git clone` in the command line, or
- Use GitHub Desktop (recommended):
- Download and install from [https://desktop.github.com/](https://desktop.github.com/?ref=coolify)
- Open GitHub Desktop and login with your GitHub account
- Click on `File` -> `Clone Repository` select `github.com` as the repository location, then select your forked Coolify repository, choose the local path and then click `Clone`
4. Open the cloned Coolify Repository in your chosen code editor.
## 4. Set up Environment Variables
1. In the Code Editor, locate the `.env.development.example` file in the root directory of your local Coolify repository.
2. Duplicate the `.env.development.example` file and rename the copy to `.env`.
3. Open the new `.env` file and review its contents. Adjust any environment variables as needed for your development setup.
4. If you encounter errors during database migrations, update the database connection settings in your `.env` file. Use the IP address or hostname of your PostgreSQL database container. You can find this information by running `docker ps` after executing `spin up`.
5. Save the changes to your `.env` file.
## 5. Start Coolify
1. Open a terminal in the local Coolify directory.
2. Run the following command in the terminal (leave that terminal open):
```bash
spin up
```
> [!NOTE]
> You may see some errors, but don't worry; this is expected.
3. If you encounter permission errors, especially on macOS, use:
```bash
sudo spin up
```
> [!NOTE]
> If you change environment variables afterwards or anything seems broken, press Ctrl + C to stop the process and run `spin up` again.
## 6. Start Development
1. Access your Coolify instance:
- URL: `http://localhost:8000`
- Login: `test@example.com`
- Password: `password`
2. Additional development tools:
| Tool | URL | Note |
|------|-----|------|
| Laravel Horizon (scheduler) | `http://localhost:8000/horizon` | Only accessible when logged in as root user |
| Mailpit (email catcher) | `http://localhost:8025` | |
| Telescope (debugging tool) | `http://localhost:8000/telescope` | Disabled by default |
> [!NOTE]
> To enable Telescope, add the following to your `.env` file:
> ```env
> TELESCOPE_ENABLED=true
> ```
## 7. Create a Pull Request
1. After making changes or adding a new service:
- Commit your changes to your forked repository.
- Push the changes to your GitHub account.
2. Creating the Pull Request (PR):
- Navigate to the main Coolify repository on GitHub.
- Click the "Pull requests" tab.
- Click the green "New pull request" button.
- Choose your fork and branch as the compare branch.
- Click "Create pull request".
3. Filling out the PR details:
- Give your PR a descriptive title.
- Use the Pull Request Template provided and fill in the details.
> [!IMPORTANT]
> Always set the base branch for your PR to the `next` branch of the Coolify repository, not the `main` branch.
4. Submit your PR:
- Review your changes one last time.
- Click "Create pull request" to submit.
> [!NOTE]
> Make sure your PR is out of draft mode as soon as it's ready for review. PRs that are in draft mode for a long time may be closed by maintainers.
After submission, maintainers will review your PR and may request changes or provide feedback.
## Development Notes
When working on Coolify, keep the following in mind:
1. **Database Migrations**: After switching branches or making changes to the database structure, always run migrations:
```bash
docker exec -it coolify php artisan migrate
```
2. **Resetting Development Setup**: To reset your development setup to a clean database with default values:
```bash
docker exec -it coolify php artisan migrate:fresh --seed
```
3. **Troubleshooting**: If you encounter unexpected behavior, ensure your database is up-to-date with the latest migrations and if possible reset the development setup to eliminate any environment-specific issues.
> [!IMPORTANT]
> Forgetting to migrate the database can cause problems, so make it a habit to run migrations after pulling changes or switching branches.
## Resetting Development Environment
If you encounter issues or break your database or something else, follow these steps to start from a clean slate (works since `v4.0.0-beta.342`):
1. Stop all running containers `ctrl + c`.
2. Remove all Coolify containers:
```bash
docker rm coolify coolify-db coolify-redis coolify-realtime coolify-testing-host coolify-minio coolify-vite-1 coolify-mail
```
3. Remove Coolify volumes (it is possible that the volumes have no `coolify` prefix on your machine, in that case remove the prefix from the command):
```bash
docker volume rm coolify_dev_backups_data coolify_dev_postgres_data coolify_dev_redis_data coolify_dev_coolify_data coolify_dev_minio_data
```
4. Remove unused images:
```bash
docker image prune -a
```
5. Start Coolify again:
```bash
spin up
```
6. Run database migrations and seeders:
```bash
docker exec -it coolify php artisan migrate:fresh --seed
```
After completing these steps, you'll have a fresh development setup.
> [!IMPORTANT]
> Always run database migrations and seeders after switching branches or pulling updates to ensure your local database structure matches the current codebase and includes necessary seed data.

## How to contribute
- This is a temporary guide until the v5 docker architecture & development setup is ready.
1. Fork the repository
2. Create a new branch or create a branch with the same name as one of the upstream branches
3. Sync your fork with the upstream branches
4. Clone and checkout the code locally
5. Copy `.env.example` to a new `.env` file (no changes should be needed)
6. As the v5 docker architecture is not ready yet, you need to install PHP, composer and bun locally
6.1. Install PHP, composer and the laravel installer [https://laravel.com/docs/12.x/installation#installing-php](https://laravel.com/docs/12.x/installation#installing-php)
6.2. Install bun [https://bun.com/docs/installation](https://bun.com/docs/installation)
7. Run `composer install` to install PHP dependencies
8. Run `bun install` to install JS dependencies
9. Run `composer run dev` to create an sqlite database, generate an APP_KEY, migrate the database and run the development server
10. Access the application at `http://localhost:8000`
