小编Ste*_*FAQ的帖子

在这个官方文档中,它可以在yaml配置文件中运行命令:

http://kubernetes.io/v1.1/docs/user-guide/configuring-containers.html

apiVersion: v1
kind: Pod
metadata:
  name: hello-world
spec:  # specification of the pod’s contents
  restartPolicy: Never
  containers:
  - name: hello
    image: "ubuntu:14.04"
    env:
    - name: MESSAGE
      value: "hello world"
    command: ["/bin/sh","-c"]
    args: ["/bin/echo \"${MESSAGE}\""]

如果我想运行多个命令,该怎么办？

我在 Ansible 2 中获取匹配的正则表达式模式时遇到问题。有人可以帮助我理解我做错了什么吗？谢谢。

--- # Disable auto update for Ubuntu
- hosts: nonedgeLinux
  become: yes
  tasks:
    - name: disable auto updates
      replace:
        dest: /etc/apt/apt.conf.d/50unattended-upgrades
        regexp: '(?:[ \t]*\"\${distro_id}:\${distro_codename}-security\";)'
        replace: '//  "\${distro_id}:\${distro_codename}-security\";'

我使用https://regex101.com/根据正在搜索的文件内容的复制/粘贴来验证正则表达式。此测试报告正则表达式模式是正确的。每次在 Ubuntu 16.04.2 机器上运行时，我都会得到以下结果：
