Drone kaniko plugin uses kaniko to build and publish Docker images to a container registry.
Plugin images are published with 1.6.0 as well as 1.9.1 kaniko version from 1.5.1 release tag. plugins/kaniko:<release-tag> uses 1.6.0 version while plugins/kaniko:<release-tag>-kaniko1.9.1 uses 1.9.1 version. Similar convention is used for plugins/kaniko-ecr & plugins/kaniko-gcr images as well.
Build the binaries with the following commands:
export GOOS=linux
export GOARCH=amd64
export CGO_ENABLED=0
export GO111MODULE=on
go build -v -a -tags netgo -o release/linux/amd64/kaniko-docker ./cmd/kaniko-docker
go build -v -a -tags netgo -o release/linux/amd64/kaniko-gcr ./cmd/kaniko-gcr
go build -v -a -tags netgo -o release/linux/amd64/kaniko-ecr ./cmd/kaniko-ecr
go build -v -a -tags netgo -o release/linux/amd64/kaniko-acr ./cmd/kaniko-acrBuild the Docker images with the following commands:
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/kaniko .
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/acr/Dockerfile.linux.amd64 --tag plugins/kaniko-acr .
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/kaniko-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/kaniko-ecr .docker run --rm \
-e PLUGIN_TAGS=1.2,latest \
-e PLUGIN_DOCKERFILE=/drone/Dockerfile \
-e PLUGIN_REPO=foo/bar \
-e PLUGIN_USERNAME=foo \
-e PLUGIN_PASSWORD=bar \
-v $(pwd):/drone \
-w /drone \
plugins/kaniko:linux-amd64With expanded tagging enabled, semantic versions can be passed to PLUGIN_TAGS directly for expansion.
Note: this feature only works for build labels. Artifact labels are not supported.
docker run --rm \
-e PLUGIN_TAGS=v1.2.3,latest \
-e PLUGIN_EXPAND_TAG=true \
-v $(pwd):/drone \
-w /drone \
plugins/kaniko:linux-amd64would both be equivalent to
PLUGIN_TAGS=1,1.2,1.2.3,latest
This allows for passing $DRONE_TAG directly as a tag for repos that use semver tags.
To avoid confusion between repo tags and image tags, PLUGIN_EXPAND_TAG also recognizes a semantic version
without the v prefix. As such, the following is also equivalent to the above:
docker run --rm \
-e PLUGIN_TAGS=1.2.3,latest \
-e PLUGIN_EXPAND_TAG=true \
-v $(pwd):/drone \
-w /drone \
plugins/kaniko:linux-amd64The auto tag feature of docker plugin is also supported.
When auto tagging is enabled, if any of the case is matched below, a docker build will be pushed with auto generated tags. Otherwise the docker build will be skipped.
Note: this feature only works for build labels. Artifact labels are not supported.
docker run --rm \
-e DRONE_COMMIT_REF=refs/tags/v1.2.3 \
-e PLUGIN_REPO=foo/bar \
-e PLUGIN_USERNAME=foo \
-e PLUGIN_PASSWORD=bar \
-e PLUGIN_AUTO_TAG=true \
-v $(pwd):/drone \
-w /drone \
plugins/kaniko:linux-amd64Tags to push:
- 1.2.3
- 1.2
- 1
docker run --rm \
-e DRONE_COMMIT_REF=refs/heads/master \

-e PLUGIN_AUTO_TAG=true \
-v $(pwd):/drone \
