## Versioning

The tags follow the major version of Docker, e.g. `19`, the minor and patch part reflects the "version" of the plugin. A full example would be `19.6.5`. Minor versions may introduce breaking changes, while patch versions may be considered non-breaking.

## 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 dist/drone-docker ./cmd/drone-docker/
```

Build the Docker image with the following command:

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