experiment: schedule pod with pod.yaml

[hexfusion]

Using go bindings consume a pod spec and schedule a new pod. We will want to decode the file to v1.Pod so we can add what we want such as env, name etc before scheduling.

podman play kube pod.yaml

package main

import (
	"fmt"

	v1 "k8s.io/api/apps/v1"
	"k8s.io/client-go/kubernetes/scheme"
)

var podYaml = `
apiVersion: v1
kind: Pod
metadata:
  labels:
    app: demo-pod
  name: demo-pod
spec:
  containers:
  - image: quay.io/libpod/alpine_nginx:latest
    name: demo
    ports:
    - containerPort: 80
      hostPort: 8000

func main() {
	decode := scheme.Codecs.UniversalDeserializer().Decode
	obj, _, err := decode([]byte(podYamlBytes, nil, nil)
	if err != nil {
		fmt.Printf("%#v", err)
	}

	pod := obj.(*v1.Pod)

	fmt.Printf("%#v\n", pod)
}
