# Docker Image: Nginx

This image is used together with [wayofdev/docker-php-dev](https://github.com/wayofdev/docker-php-dev) and other WOD images, to create local development environment for our projects.
This **Docker image** provides a streamlined **Nginx** setup optimized for **local PHP development environments**.

![Screenshot](.github/assets/screenshot.png)
It's designed to seamlessly integrate with [wayofdev/docker-php-dev](https://github.com/wayofdev/docker-php-dev) and other (WOD) images, creating an efficient local development ecosystem for web projects.

## ⚙️ Development
<br>

## 🌟 Why Choose This Image for Local Development?

To install dependencies and start development you can check contents of our `Makefile`
- **Ansible-based Configuration:** Easily customizable through Ansible templates
- **PHP-FPM Optimized:** Pre-configured to work with PHP-FPM for fast local testing and development
- **SSL Ready:** Includes built-in support for HTTPS using self-signed certificates, mimicking production environments locally
- **Developer Friendly:** Packed with tools and configurations to enhance local development workflows
- **Flexible Deployment:** Includes a `k8s-alpine` variant for testing Kubernetes setups locally
- **Lightweight:** Based on **Alpine Linux** for minimal footprint and faster local builds
- **Multi-arch Support:** Works on both **x86 (AMD64)** and **ARM64** architectures, supporting various development machines
- **Regular Updates:** Maintained and updated frequently to align with the latest development practices

### → Requirements
Perfect for developing **Laravel** applications, **Symfony** projects, or any **PHP-based web services** in a local environment that closely mirrors production setups.

For testing purposes we use **goss** and **dgoss**, follow installation instructions on [their official README](https://github.com/aelsabbahy/goss/blob/master/extras/dgoss/README.md)
Provides foundation for creating, testing, and debugging your web applications locally.

```
Building all images:
#### This configuration includes
```bash
make build IMAGE_TEMPLATE=dev-alpine
make build IMAGE_TEMPLATE=k8s-alpine
```
- An `app` service using the `wayofdev/php-dev` image for PHP processing.
- A `web` service using a [custom Nginx image](https://github.com/wayofdev/docker-nginx) for serving the application.
- Network configuration for both default and shared networks.
- Volume mounts for application code, assets, and configuration files.
- Environment variables for PHP and Xdebug configuration.
- Traefik labels for reverse proxy and SSL termination.

#### Real-world Example

For a comprehensive, real-world example of how to use this image in a Docker Compose setup, please refer to the [wayofdev/laravel-starter-tpl](https://github.com/wayofdev/laravel-starter-tpl) repository. This template provides a fully configured development environment for Laravel projects using the `wayofdev/php-dev` image.

## 🧪 Testing
## ⚙️ Configuration

Testing default image:
The Nginx image is pre-configured for optimal performance with PHP applications, but you can customize it further to suit your specific needs.

```bash
make test
```
### → Default Configuration

To test all images:
The default configuration is generated using Ansible templates and includes:

```bash
make test IMAGE_TEMPLATE=dev-alpine
make test IMAGE_TEMPLATE=k8s-alpine
- Optimized settings for PHP-FPM
- SSL/TLS support with self-signed certificates
- Gzip compression enabled
- Basic security headers

### → Custom Configuration

While the configuration is primarily managed through Ansible templates, you can override specific settings:

1. **Environment Variables:** The image uses the following environment variables:

| Variable | Default Value | Description |
|------------------------|---------------|---------------------------------------|
| PHP_UPSTREAM_CONTAINER | app | The name of the PHP-FPM container |
| PHP_UPSTREAM_PORT | 9000 | The port of the PHP-FPM container |

Set these in your `docker-compose.yml` file:

```yaml
services:
web:
image: wayofdev/nginx:k8s-alpine-latest
environment:
- PHP_UPSTREAM_CONTAINER=my-php-app
- PHP_UPSTREAM_PORT=9001
```

2. **Volume Mounts:** For more extensive customizations, you can mount your own config files:

```yaml
services:
web:
image: wayofdev/nginx:k8s-alpine-latest
volumes:
- ./custom-nginx.conf:/etc/nginx/nginx.conf
- ./custom-default.conf:/etc/nginx/conf.d/default.conf
```

### → SSL Configuration

The image includes self-signed SSL certificates. To use your own:

```yaml
services:
web:
image: wayofdev/nginx:k8s-alpine-latest
volumes:
- ./certs/cert.pem:/etc/nginx/ssl/cert.pem
- ./certs/key.pem:/etc/nginx/ssl/key.pem
```

### → Advanced Configuration

For more advanced configurations:

1. Fork this repository
2. Modify the Ansible templates in the `src` directory
3. Regenerate the Dockerfiles using `make generate`
4. Build your custom image

### → Code quality tools
## 🔨 Development

Run **yamllint** to validate all yaml files in project:
This project uses a set of tools for development and testing. The `Makefile` provides various commands to streamline the development process.

```bash
make lint-yaml
```
### → Requirements

- Docker
- Make
- Ansible
- goss and dgoss for testing

Run hadolint to validate created Dockerfiles:
### → Setting Up the Development Environment

Clone the repository:

```bash
make lint-docker
git clone [email protected]:wayofdev/docker-nginx.git && \
cd docker-nginx
```

Run ansible-lint to validate project files:
### → Generating Dockerfiles

Ansible is used to generate Dockerfiles and configurations. To generate distributable Dockerfiles from Jinja template source code:

```bash
make lint-ansible
make generate
```

### → Building Images

- Build the default image:

```bash
make build
```

This command builds the image specified by the `IMAGE_TEMPLATE` variable in the Makefile. By default, it's set to `k8s-alpine`.

- Build a specific image:

```bash
make build IMAGE_TEMPLATE="k8s-alpine"
```

Replace `8.3-fpm-alpine` with your desired PHP version, type, and OS.

- Build all images:

```bash
make build IMAGE_TEMPLATE="k8s-alpine"
make build IMAGE_TEMPLATE="dev-alpine"
```

These commands will build all supported image variants.

<br>

## 🧪 Testing

This project uses a testing approach to ensure the quality and functionality of the Docker images. The primary testing tool is [dgoss](https://github.com/aelsabbahy/goss/tree/master/extras/dgoss), which allows for testing Docker containers.

### → Running Tests

You can run tests using the following commands:

- Test the default image:

```bash
make test
```

This command tests the image specified by the `IMAGE_TEMPLATE` variable in the Makefile (default is `k8s-alpine`).

- Test a specific image:

```bash
make test IMAGE_TEMPLATE="k8s-alpine"
```

Replace `8.3-fpm-alpine` with your desired PHP version, type, and OS.

- Test all images:

```bash
make test IMAGE_TEMPLATE="k8s-alpine"
make test IMAGE_TEMPLATE="dev-alpine"
```

### → Test Configuration

The test configurations are defined in `goss.yaml` files, which are generated for each image variant. These files specify the tests to be run, including:

- File existence and permissions
- Process checks
- Port availability
- Package installations
- Command outputs

### → Test Process

When you run the `make test` command, the following steps occur:

1. The specified Docker image is built (if not already present).
2. dgoss runs the tests defined in the `goss.yaml` file against the Docker container.
3. The test results are displayed in the console.
