如果端口打开,Ansible Playbook应停止执行

您可以使用此任务检查应用程序是否已在运行。如果运行,它将中止播放本。

  - name: Check if service is running by querying the application port
    wait_for: 
      port: 22
      timeout: 10
      state: stopped
      msg: "Port 22 is accessible, application is already installed and running"
    register: service_status

基本上,您使用的模块 state: stopped Ansible希望端口停止监听 timeout 秒。如果端口保持运行10秒(由于没有人停止已安装的应用程序,端口将保持运行),Ansible将退出并出错。

将端口更改为23,您将看到Playbook将继续下一步:

  tasks:
  - name: Check if service is running by querying the application port
    wait_for: 
      port: 23
      timeout: 10
      state: stopped
      msg: "Port 23 is accessible, application is already installed and running"
    register: service_status

  - name: print
    debug:
      var: service_status

你不需要 register 子句,只是为我的测试添加的。

希望有帮助
