我一直在制作一个创建虚拟服务器的游戏,并通过询问用户一些问题来收集配置要求来做到这一点。

我想运行一些预先检查以显示某些虚拟服务器属性存在,我已经能够计算出除配置文件之外的所有属性。

当您运行“list ltm profile”时,您需要指定协议,然后是配置文件名称,例如“list ltm profile tcp tcp”。检查一个 LTM 配置文件很好,但我遇到的困难是当您需要检查多个配置文件时。

有没有办法可以循环我的问题并将用户输入传递给检查?假设用户想要检查以下配置文件:

list ltm profile http http
list ltm profile tcp tcp

这是问的问题:

- name: "vs_profile_type"
  prompt: "enter the profile(s) to run your pre-checks against"
  private: no 

以下是我对这出戏的预检部分的内容:

  - name: Pre-check
    bigip_command:
      server: "{{ inventory_hostname }}"
      user: "{{ remote_username }}"
      password: "{{ remote_passwd }}"
      commands:
        - "tmsh list sys global-settings hostname"
        - "tmsh show sys failover"
        - "tmsh show cm sync-status"
        - "tmsh list ltm virtual {{ vs_name }}"
        - "tmsh list ltm profile {{ vs_profile_type }}"
        - "tmsh list ltm pool {{ vs_pool }}"
        - "tmsh list ltm rule {{ vs_rule }}"
      warn: no
      validate_certs: no
    delegate_to: localhost
    when: "'active' in Active_LTM['stdout'][0]"
    register: Active_LTM_Pre_Checks 

我也在考虑用户可能不想要配置文件的事实,所以如果他们按下回车,我需要跳过“list ltm profile xxx xxx”检查。在另一篇文章中,我得到了一些帮助,但是在重新设计这个实例的语法时,我似乎无法让它工作;任何想法可能与以下语法有关?

"tmsh list ltm profile {{ '{' + vs_profile_type + '}' if vs_profile_type else '' }} {{ '{' + vs_profile + '}' if vs_profile else '' }}"

我们以这种方式完成了这项工作。

向用户提出的问题:

- name: "vs_profile_type"
  prompt: "enter the profile to run your pre-checks against [Enter in the following format: tcp tcp, http http]"
  private: no

我们最终在一个单独的任务中对配置文件运行此检查:

  - name: Profile_Pre-check
    bigip_command:
      server: "{{ inventory_hostname }}"
      user: "{{ remote_username }}"
      password: "{{ remote_passwd }}"
      commands:
         - "tmsh list ltm profile {{ item }}"
      validate_certs: no
    delegate_to: localhost
    with_items:
      - "{{ vs_profile_type.split(',') }}"
    when: "'active' in Active_LTM['stdout'][0]"
    register: Active_LTM_Pre_Checks

这是该检查/任务的播放:

- name: "vs_profile_type"
  prompt: "enter the profile to run your pre-checks against [Enter in the following format: tcp tcp, http http]"
  private: no

        bigip_command:
          server: "{{ inventory_hostname }}"
          user: "{{ remote_username }}"
          password: "{{ remote_passwd }}"
          commands:
  tasks:
      - name : Checking which LTM is active....
        bigip_command:
          server: "{{ inventory_hostname }}"
          user: "{{ remote_username }}"
          password: "{{ remote_passwd }}"
          commands:
            - "tmsh show sys failover"
          validate_certs: no
        delegate_to: localhost
        register: Active_LTM

      - name: The active LTMs management IP is....
        block:
          - debug:
              var: Active_LTM.stdout[0]

      - name: Profile_Pre-check
        bigip_command:
          server: "{{ inventory_hostname }}"
          user: "{{ remote_username }}"
          password: "{{ remote_passwd }}"
          commands:
             - "tmsh list ltm profile {{ item }}"
          validate_certs: no
        delegate_to: localhost
        with_items:
          - "{{ vs_profile_type.split(',') }}"
        when: "'active' in Active_LTM['stdout'][0]"
        register: Active_LTM_Pre_Checks

      - name: Please verify the profile pre-checks are correct
        debug:
          var: Active_LTM_Pre_Checks.stdout_lines
