k8s 使用本地镜像的时候

k8s默认会从远端拉取镜像，其配置参数imagePullPolicy为Always
containers:
- name: demo
image: image
imagePullPolicy: Never

pod报错"Back-off restarting failed container"解决办法
containers:
      - name: demo
        image: python：3.6
        imagePullPolicy: IfNotPresent # 这个设置 会从本地先找，没有从远处拉取
        command: [ "/bin/bash", "-ce", "tail -f /dev/null" ]
