Kubernetes 中常用模板

Pod 基础属性模板

apiVersion: v1
kind: Pod
metadata:
  name: test
  namespace: liangxiao
  annotations:
    user: "liangxiao"
  labels:
    app: centos
spec:
  activeDeadlineSeconds: 6000    # 逾期设置，如果超过这个时间6000秒，Pod 会被退出，并设置DeadlineExceeded状态，并且不会重新拉起
  dnsPolicy: ClusterFirst
  hostAliases:            # 设置pod 中 /etc/hosts 文件内容
  - ip: "8.8.8.8"
    hostnames:
    - "www.google.com"
    - "www.google.cn"

  imagePullSecrets:        # 指定镜像拉取的密钥凭据
    - name: centos
  hostIPC: true            # 设定Pod 与 宿主之间的共享进程通信
  restartPolicy: Always        # 设定Pod 的重启策略
  hostname: centos
#  hostNetwork: true        # 设定Pod 与 宿主之间的网络命名空间共享；注意：hostNetwork 不可以和 hostname 共存
  hostPID: true
  initContainers:
  - name: init
    image: centos:7
    command: ["/bin/bash"]
    args: ["-c","echo hello world > /workdir/index.html"]
    volumeMounts:
    - name: workdir
      mountPath: "/workdir"

  containers:
  - name: centos
    image: 'centos:7'
    imagePullPolicy: Always

    volumeMounts:
    - name: workdir
      mountPath: "/usr/share/nginx/html"

    command: ["/bin/bash"]
    args: ["-c","while true; do echo ok ; sleep 10 ; done"]
    readinessProbe:
      exec:
        command:
        - ls
        - /home
      initialDelaySeconds: 3
      timeoutSeconds: 1
  terminationGracePeriodSeconds: 120    # 设定优雅退出时间;
  volumes:
  - name: workdir
    emptyDir: {}
