k8s部署busybox编排文件

在测试验证K8S容器的时候，经常会使用busybox，下面是k8s部署busybox编排文件，方便参考：

apiVersion: apps/v1
kind: Deployment
metadata:
  name: busybox
  namespace: default
spec:
  selector:
    matchLabels:
      app: busybox
  replicas: 2
  template:
    metadata:
      labels:
        run: busybox
    spec:
      containers:
      - name: busybox
        image: busybox:latest
        args:
        - /bin/sh
        - -c
        - sleep 10; touch /tmp/healthy; sleep 30000
        readinessProbe:
          exec:
            command:
            - cat
            - /tmp/healthy
          initialDelaySeconds: 10
          periodSeconds: 5
