# Build and Push Docker Image Action

This GitHub Action builds and pushes a Docker image to a Docker registry. It uses Docker to build the image from a specified context directory, tags the image with a version and the latest tag, and pushes both tags to the Docker registry.

## Inputs

### `username`

**Required** The username for the Docker registry.

### `password`

**Required** The password for the Docker registry.

### `path`

**Optional** The path to the Docker context directory. Default is `.`.

### `registry`

**Required** The Docker registry URL.

### `owner`

**Required** The owner of the Docker repository.

## Example Usage

```yaml
name: Build and Push Docker Image

on:
  push:
    branches:
      - main

jobs:
  build:
    runs-on: ubuntu-latest

    steps:
      - name: Checkout repository
        uses: actions/checkout@v2

      - name: Build and Push Docker Image
        uses: Punga78/gitea-docker-build-and-push-version
        with:
          username: ${{ secrets.DOCKER_USERNAME }}
          password: ${{ secrets.DOCKER_PASSWORD }}
          registry: 'gitea.com'
          owner: 'Punga78'
          path: '.'

Details

This action performs the following steps:

1. Retrieves the input parameters.
2. Reads the package.json and optionally build-info.json from the specified context path.
3. Constructs the Docker image name and tags.
4. Builds the Docker image using docker buildx build.
5. Tags the image with both the version and latest tags.
6. Pushes both tags to the Docker registry.

If the build-info.json file does not exist, the build number defaults to 0.

Note

Ensure that you have the required secrets DOCKER_USERNAME and DOCKER_PASSWORD set in your GitHub repository settings. These will be used to authenticate with the Docker registry.
