Sourceability Kustomize Plugins

KEP 897

This plugin addresses kubernetes-sigs/kustomize#720 by implementing the StrategicMergePatch from KEP 897.

Note that I've encountered issues applying patches to resources with prefixes/suffixes. I'm assuming that other issues like exist with this plugin.

This repository contains one very simple example kustomization, that can be built with:

docker run \
    -it --rm \
    -w /app -v $PWD:/app \
    sourceability/kustomize-plugins \
    build --enable_alpha_plugins examples/deployment-patch

Which should output:

apiVersion: apps/v1
kind: Deployment
metadata:
  labels:
    app: elasticsearch
  name: elasticsearch
spec:
  selector:
    matchLabels:
      app: elasticsearch

      nodeSelector:
        env: prod
