Kaniko

This Task builds source into a container image using Google's kaniko tool.

kaniko doesn't depend on a Docker daemon and executes each command within a Dockerfile completely in userspace. This enables building container images in environments that can't easily or securely run a Docker daemon, such as a standard Kubernetes cluster.

Kaniko website

kaniko is meant to be run as an image, gcr.io/kaniko-project/executor:v1.5.1. This makes it a perfect tool to be part of Tekton.

Install the Task

kubectl apply -f https://raw.githubusercontent.com/tektoncd/catalog/main/task/kaniko/0.2/kaniko.yaml

Parameters

IMAGE: The name (reference) of the image to build.
DOCKERFILE: The path to the Dockerfile to execute (default: ./Dockerfile)
CONTEXT: The build context used by Kaniko (default: ./)
EXTRA_ARGS: Additional args to pass to the Kaniko executor.
BUILDER_IMAGE: The Kaniko executor image to use (default: gcr.io/kaniko-project/executor:v1.5.1)

Workspaces

source: A Workspace containing the source to build.

Results

IMAGE-DIGEST: The digest of the image just built.

ServiceAccount

kaniko builds an image and pushes it to the destination defined as a parameter. In order to properly authenticate to the remote container registry, it needs to have the proper credentials. This is achieved using a ServiceAccount.

For an example on how to create such a ServiceAccount to push an image to DockerHub, see the Authentication documentation page.

Platforms

The Task can be run on linux/amd64 platform.

Usage

This TaskRun runs the Task to fetch a Git repo, and build and push a container image using Kaniko
