By default, many Gitea runner environments do not include a Docker installation.<br/>
This can be problematic because Docker is required by many container-related workflows, including building, tagging, and publishing container images.

This action installs Docker (using the script at https://get.docker.com) when required and optionally configures Docker Buildx for modern image build workflows. Existing Docker installations are automatically detected and reused.<br/>
This allows container-based workflows to run consistently across Gitea runners without requiring every repository to implement its own Docker setup logic.


## Inputs

| Name | Description | Default |
|------|-------------|---------|
| `setup-buildx` | Configure Docker Buildx after Docker installation. | `true` |

## Usage

### Install Docker with Buildx (default)
```yaml
- name: Setup docker
  uses: https://git.claeyscloud.com/david/gitea-actions/setup-docker@main
```

### Install Docker without Buildx

```yaml
- name: Setup Docker
  uses: https://git.claeyscloud.com/david/gitea-actions/setup-docker@main
  with:
    setup-buildx: false
```
This installs Docker if required but skips Docker Buildx configuration
