Question

我设置了一个最终具有此值的寄存器变量：

ok: [10.xx.xx.xx] => {
    "yum_sec_upd.stdout_lines": [
        "Loaded plugins: fastestmirror", 
        "Loading mirror speeds from cached hostfile", 
        " * base: mirrors.usinternet.com", 
        " * epel: mirror.steadfast.net", 
        " * extras: mirror.lax.hugeserver.com", 
        " * updates: centos.mirrors.tds.net", 
        "CESA_2017__0086 Important/Sec. kernel-3.10.0-514.6.1.el7.x86_64", 
        "CESA_2017__0086 Important/Sec. kernel-tools-3.10.0-514.6.1.el7.x86_64", 
        "CESA_2017__0086 Important/Sec. kernel-tools-libs-3.10.0-514.6.1.el7.x86_64", 
        "CESA_2017__0086 Important/Sec. python-perf-3.10.0-514.6.1.el7.x86_64", 
        "updateinfo list done"
    ]
}

如何检查字符串＆＃34; Sec。＆＃34;是否存在于yum_sec_upd.stdout_lines字符串数组中？我想这样做

- name: Send mail for security updates
  mail: # mail parms here
  when: "'Sec.' in yum_sec_upd.stdout_lines[]"

如果您要注册命令的输出，只需使用stdout而不是stdout_lines：

- name: Send mail for security updates
  mail: # mail parms here
  when: 'Sec.' in yum_sec_upd.stdout

要检查列表是否包含子字符串，您可以使用例如：

when: yum_sec_upd.stdout_lines | select('search', 'Sec.') | list | length > 0

在Ansible中，如何检查值是否在数组中的某个元素中？
