Knative Build Templates

This repository contains a library of BuildTemplate resources which are designed to be reusable by many applications.

Each build template is in a separate directory along with a README.md and a Kubernetes manifest, so you can choose which build templates to install on your cluster.

Build Templates Kinds

There are two kinds of build templates:

1. ClusterBuildTemplates with a Cluster scope
2. BuildTemplates with a Namespace scope

A default kind of BuildTemplate is used if the field kind is not set.

Using Build Templates

First, install a build template onto your cluster:

$ kubectl apply -f buildpack.yaml
buildtemplate "buildpack" created

You can see which build templates are installed using kubectl as well:

$ kubectl get buildtemplates
NAME       AGE
buildpack  3s

OR

$ kubectl get clusterbuildtemplates
NAME        AGE
buildpack   9s

With the build template installed, you can define a build that uses that template, being sure to provide values for required parameters:

apiVersion: build.knative.dev/v1alpha1
kind: Build
metadata:
  name: buildpack-build
spec:
  source:
    git:
      url: https://github.com/my-user/my-repo
      revision: master
  template:
    name: buildpack
    kind: BuildTemplate # (or ClusterBuildTemplate)
    arguments:
    - name: IMAGE
      value: us.gcr.io/my-project/my-app

Next, create the build you defined:

$ kubectl apply -f build.yaml
build "buildpack-build" created

You can check the status of the build using kubectl:

$ kubectl get build buildpack-build -oyaml
