Installing kpack

Prerequisites

  1. A Kubernetes cluster version 1.12 or later
  2. kubectl CLI
  3. Cluster-admin permissions for the current user.
  4. Accessible Docker V2 Registry

Installing-kpack

  1. Download the most recent github release.

    kubectl apply  --filename release.yaml

  2. Ensure that the kpack controller has a status of Running using kubectl get.

    kubectl get pods --namespace kpack --watch

  3. Create a ClusterBuilder resource. A ClusterBuilder is a reference to a Cloud Native Buildpacks builder image. The Builder image contains buildpacks that will be used to build images with kpack. We recommend starting with the cloudfoundry/cnb:bionic image which has support for Java, Node and Go.

apiVersion: build.pivotal.io/v1alpha1
kind: ClusterBuilder
metadata:
  name: default-builder
spec:
  image: cloudfoundry/cnb:bionic

Apply the ClusterBuilder yaml to the cluster

kubectl apply -f <name-of-cluster-builder-file.yaml>

Ensure that kpack has processed the builder by running

kubectl get clusterbuilder default-builder -o yaml

You should see output similar to the following:

apiVersion: build.pivotal.io/v1alpha1
kind: ClusterBuilder
metadata:
  creationTimestamp: "2019-09-19T15:05:01Z"
  generation: 1
  name: default-builder
  resourceVersion: "21823241"
