A thin shim-wrapper around the official Google Kaniko Docker image to make it behave like the Drone Docker plugin.
Example .drone.yml for Drone 1.0

docker run -it --rm -w /src -v $PWD:/src -e PLUGIN_USERNAME=${DOCKER_USERNAME} -e PLUGIN_PASSWORD=${DOCKER_PASSWORD} -e PLUGIN_REPO=banzaicloud/drone-kaniko-test -e PLUGIN_TAGS=test -e PLUGIN_DOCKERFILE=Dockerfile.test banzaicloud/drone-kaniko
Start a Docker registry at 127.0.0.1:5000:
docker run -d -p 5000:5000 --restart always --name registry --hostname registry.local registry:2
Add the following lines to plugin.sh's final command and build a new image from it:
+ --cache=true \
+ --cache-repo=127.0.0.1:5000/${PLUGIN_REPO} \
docker build -t banzaicloud/drone-kaniko .
Warm up the alpine image to the cache:
docker run -v $PWD:/cache gcr.io/kaniko-project/warmer:latest --image=alpine:3.8
Run the builder on the host network to be able to access the registry:
docker run --net=host -it --rm -w /src -v $PWD:/cache -v $PWD:/src -e DOCKER_USERNAME=${DOCKER_USERNAME} -e DOCKER_PASSWORD=${DOCKER_PASSWORD} -e PLUGIN_REPO=banzaicloud/drone-kaniko-test -e PLUGIN_TAGS=test -e PLUGIN_DOCKERFILE=Dockerfile.test banzaicloud/drone-kaniko
