Run the builder (on the host network to be able to access the registry, if any specified) with mounting the local disk cache, this example pushes to Docker Hub:

docker run --net=host -it --rm -w /src -v $PWD:/cache -v $PWD:/src -e PLUGIN_USERNAME=${DOCKER_USERNAME} -e PLUGIN_PASSWORD=${DOCKER_PASSWORD} -e PLUGIN_REPO=banzaicloud/drone-kaniko-test -e PLUGIN_TAGS=test -e PLUGIN_DOCKERFILE=Dockerfile.test -e PLUGIN_CACHE=true banzaicloud/drone-kaniko

The very same example just pushing to GCR instead of Docker Hub:
