Drone plugin to build multiarch Docker images.

## Docker Tags

Tags are following the main Docker version e.g. `19.03`, the second part is reflecting the plugin "version". A full example would be `19.03.5`.

## Build

Build the binary with the following command:

```Shell
export GOOS=linux
export GOARCH=amd64
export CGO_ENABLED=0
export GO111MODULE=on

go build -v -a -tags netgo -o release/drone-docker
```

Build the Docker image with the following command:

```Shell
docker build --file docker/Dockerfile.amd64 --tag thegeeklab/drone-docker .
```

## Usage

> Notice: Be aware that the tis plugin requires privileged capabilities, otherwise the integrated Docker daemon is not able to start.

```console
docker run --rm \
  -e PLUGIN_TAG=latest \
  -e PLUGIN_REPO=octocat/hello-world \
  -e DRONE_COMMIT_SHA=00000000 \
  -v $(pwd):$(pwd) \
