Basic Component Example

This directory provides a basic example of a component building process, somewhat arbitrarily picking etcd as the concrete example.

The etcd-component.yaml was generated frome the etcd-component-builder.yaml using

go run ../../cmd/bundlectl/main.go build --input-file=etcd-component-builder.yaml > etcd-component.yaml

Patching can be done with:

go run ../../cmd/bundlectl/main.go patch \
  --input-file=etcd-component.yaml \
  --options-file=options.yaml

Alternatively, a subset of patches can be applied with:

go run ../../cmd/bundlectl/main.go patch \
  --input-file=etcd-component.yaml \
  --options-file=options.yaml \
  --patch-annotations=build-label-experiment=test

Patch Templates

Patch Templates are a way to customize a kubernetes file. Here is an example Patch Template:

apiVersion: bundle.gke.io/v1alpha1
kind: PatchTemplate
template: |
  apiVersion: v1
  kind: Pod
  metadata:
    namespace:
      {{.namespace}}

Patch Templates apply to objects that match the apiVersion, kind, and metadata.name specified in the template. Thus, these fields cannot be modified with PatchTemplates.
