Drone plugin to build and publish Docker images to a container registry. For the usage information and a listing of the available options please take a look at [the docs](http://plugins.drone.io/drone-plugins/drone-docker/).

## Build

Build the binaries with the following commands:

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

go build -v -a -tags netgo -o release/linux/amd64/drone-docker ./cmd/drone-docker
go build -v -a -tags netgo -o release/linux/amd64/drone-gcr ./cmd/drone-gcr
go build -v -a -tags netgo -o release/linux/amd64/drone-ecr ./cmd/drone-ecr
go build -v -a -tags netgo -o release/linux/amd64/drone-heroku ./cmd/drone-heroku
```

## Docker

Build the Docker images with the following commands:

```console
docker build \
  --label org.label-schema.build-date=$(date -u +"%Y-%m-%dT%H:%M:%SZ") \
  --label org.label-schema.vcs-ref=$(git rev-parse --short HEAD) \
  --file docker/docker/Dockerfile.linux.amd64 --tag plugins/docker .

docker build \
  --label org.label-schema.build-date=$(date -u +"%Y-%m-%dT%H:%M:%SZ") \
  --label org.label-schema.vcs-ref=$(git rev-parse --short HEAD) \
  --file docker/gcr/Dockerfile.linux.amd64 --tag plugins/gcr .

docker build \
  --label org.label-schema.build-date=$(date -u +"%Y-%m-%dT%H:%M:%SZ") \
  --label org.label-schema.vcs-ref=$(git rev-parse --short HEAD) \
  --file docker/ecr/Dockerfile.linux.amd64 --tag plugins/ecr .

docker build \
  --label org.label-schema.build-date=$(date -u +"%Y-%m-%dT%H:%M:%SZ") \
  --label org.label-schema.vcs-ref=$(git rev-parse --short HEAD) \
  --file docker/heroku/Dockerfile.linux.amd64 --tag plugins/heroku .
```

## Usage

> Notice: Be aware that the Docker plugin currently 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=d8dbe4d94f15fe89232e0402c6e8a0ddf21af3ab \
  -v $(pwd):$(pwd) \
  -w $(pwd) \
  --privileged \
  plugins/docker --dry-run
```
