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 when required and optionally configures Docker Buildx for modern image build workflows. Existing Docker installations are automatically detected and reused.
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
