This action sets up a NGINX web server.

* Runs on Linux, macOS and Windows GitHub runners
    * On Linux, assumes it is pre-installed
    * On macOS, installs using [Homebrew](https://formulae.brew.sh/formula/nginx)
    * On Windows, assumes it is pre-installed
* Overrides default configuration with a simpler and more cross-platform consistent one (can be user-supplied)
* As output, provides the location of the root html dir, process ID, and access and error log files.
* [Easy to check](action.yml) that IT DOES NOT contain malicious code.

See also [action-setup-postgis](https://github.com/nyurik/action-setup-postgis) to configure PostGIS service.

## Usage

```yaml
steps:
  - uses: nyurik/action-setup-nginx@v1
    id: nginx

  - run: |
      echo "Hello, world!" > "${{ steps.nginx.outputs.html-dir }}/index.html"
      
      curl http://localhost:${{ steps.nginx.outputs.port }}/
      # Expected output: Hello, world!

      cat "${{ steps.nginx.outputs.access-log }}"
      # Expected to contain a line with   GET /   HTTP/1.1   200
```
