{{< hint type=important >}}
Be aware that the this plugin requires [privileged](https://woodpecker-ci.org/docs/usage/workflow-syntax#privileged-mode) capabilities, otherwise the integrated Docker daemon is not able to start.
{{< /hint >}}

```yaml
steps:
  - name: docker
    image: quay.io/thegeeklab/wp-docker-buildx
    privileged: true
    settings:
      username: octocat
      password: random-secret
      repo: octocat/example
      tags: latest

### Examples

#### Push to other registries than DockerHub

If the created image is to be pushed to registries other than the default DockerHub, it is necessary to set `registry` and `repo` as fully-qualified name.

**GHCR:**

```yaml
steps:
  - name: docker
    image: quay.io/thegeeklab/wp-docker-buildx
    privileged: true
    settings:
      registry: ghcr.io
      username: octocat
      password: secret-access-token
      repo: ghcr.io/octocat/example
      tags: latest
```

**AWS ECR:**

```yaml
steps:
  - name: docker
    image: quay.io/thegeeklab/wp-docker-buildx
    privileged: true
    environment:
      AWS_ACCESS_KEY_ID:
        from_secret: aws_access_key_id
      AWS_SECRET_ACCESS_KEY:
        from_secret: aws_secret_access_key
    settings:
      registry: <account_id>.dkr.ecr.<region>.amazonaws.com
      repo: <account_id>.dkr.ecr.<region>.amazonaws.com/octocat/example
      tags: latest
```

## Build

Build the binary with the following command:

```shell

Build the container image with the following command:

```shell
docker build --file Containerfile.multiarch --tag thegeeklab/wp-docker-buildx .
```

## Test

  -e PLUGIN_TAG=latest \
  -e PLUGIN_REPO=octocat/hello-world \
  -e CI_COMMIT_SHA=00000000 \
  -v $(pwd)/testdata:/build:z \
  -w /build \
  --privileged \
