# Build Workflow

This is a workflow designed to automate the process of building and pushing Docker images to the registry. The workflow is triggered through the `workflow_call` event, allowing it to be reused in other workflows or repositories.

## Usage Example

In this example, the `build` workflow is invoked with a custom `tag`, `username`, and `password`. The workflow will build and push a Docker image using the provided parameters.

```yaml
jobs:
  build:
    uses: your-repo/.github/workflows/build.yml@main
    with:
      tag: v1.0.0
      username: my-docker-username
      password: ${{ secrets.DOCKER_PASSWORD }}
      build-args: |
        PHP_VERSION=8.4
```

### Input Parameters
- **tag** (optional):
    - **Type:** `string`
    - **Default:** `latest`
    - **Description:** Tag to be assigned to the Docker image. If not provided, it defaults to `latest`.

- **username** (optional):
    - **Type:** `string`
    - **Default:** `${{ vars.REGISTRY_USERNAME }}`
    - **Description:** Username for the Docker registry authentication. Defaults to authenticated `registry` user.

- **password** (optional):
    - **Type:** `string`
    - **Default:** `${{ vars.REGISTRY_PASSWORD }}`
    - **Description:** Password for the Docker registry authentication. Defaults to authenticated `registry` user.

### Steps

1. **Checkout Code:**
    - **Action:** `actions/checkout@v4`
    - **Description:** This step checks out the code from the repository, ensuring the latest version of the code is available for building the Docker image.

2. **Login to Docker Registry:**
    - **Action:** `docker/login-action@v3`
    - **Description:** Logs into the Docker registry (`git.qlic.nl`) using the provided `username` and `password` inputs.
    - **Inputs:**
        - `registry`: Set to `git.qlic.nl`
        - `username`: Provided via `${{ inputs.username }}`
        - `password`: Provided via `${{ inputs.password }}`

3. **Build Docker Image:**
    - **Command:**
      ```bash
      docker build . -t ${{ vars.REGISTRY }}/${{ gitea.repository }}:${{ inputs.tag }} -t ${{ vars.REGISTRY }}/${{ gitea.repository }}:${{ gitea.sha }}
      ```
    - **Description:** Builds a Docker image from the current code. The image is tagged with both the user-provided `tag` (or the default `latest` if not provided) and the current Git commit SHA.

4. **Push Docker Image:**
    - **Command:**
      ```bash
      docker push ${{ vars.REGISTRY }}/${{ gitea.repository }} --all-tags
      ```
    - **Description:** Pushes the built Docker image to the Docker registry (`git.qlic.nl`), ensuring that all tags are pushed.
