Use items: for Multiple Resources in Single Manifest

Today I learned after running the kompose tool against a rather complicated application (Icinga) that the fastest possible way to create a lot of new Kubernetes resource items is not by separating them with --- as separate manifest files, but using the items keywords and putting them all effectively in the same resource file, which appears to create only a single API call.

This method has its drawbacks though since it forces a level of indentation that is pretty ugly.

apiVersion: v1
items:
  - apiVersion: v1
    kind: Service
    metadata:
      annotations:
        kompose.cmd: kompose convert -o komposed
        kompose.version: 1.26.1 (a9d05d509)
      creationTimestamp: null
      labels:
        io.kompose.service: icinga2
      name: icinga2
    spec:
      ports:
        - name: "5665"
          port: 5665
          targetPort: 5665
      selector:
        io.kompose.service: icinga2
    status:
    ...
