我正在尝试获取具有最多可用空间的 VMware 数据存储，然后使用它的 URL 在 Kubernetes 集群中创建存储类。

我正在使用模块获取信息vmware_datastore_info，如下所示：

--- 
- name: Gather info from ESXi datacenter
  hosts: localhost 
  gather_facts: false 
 
  tasks: 
  - name: Gather info from ESXi datastore 
    vmware_datastore_info: 
      hostname: '{{ vcenter_server }}' 
      username: '{{ username }}' 
      password: '{{ password }}' 
      datacenter_name: '{{ datacenter_name }}' 
      validate_certs: false 
    delegate_to: localhost 
    register: info 

  - debug: var=info.datastores

示例info.datastores结果

    ]
}

我怎样才能datastores.url从这个结果中只得到一个？

我有一个需要传递的 Ansible 剧本--extra-vars，并且想知道是否有任何方法可以根据--extra-vars变量内的值验证主机名。

示例手册test.yml

- hosts: localhost
  gather_facts: false
  vars:
    prg:
      prod_mgmt_network: "{{ ['prodsrv00']|product(range(prod_start,prod_end))|map('join')|list }}"
      test_mgmt_network: "{{ ['testsrv00']|product(range(test_start,test_end))|map('join')|list }}"
    prod_start: 4281
    prod_end: 4283
    test_start: 8281
    test_end: 8283


  tasks:
    - debug:
        var: prg.prod_mgmt_network, prg.test_mgmt_network

命令示例

ansible-playbook --extra-vars hostname=['prodsrv004281', 'prodsrv004282', 'testsrv008281', 'testsrv008282', 'testsrv008283', 'testsrv008284'] test.yml

如果主机名不在变量中，我希望任务失败。例如，testsrv008283并且testsrv008284应该使任务失败。

我有一个需要传递的 Ansible 剧本--extra-vars，并且想知道是否有任何方法可以验证该值是定义的列表值之一。

样本test.yml

- hosts: localhost
  gather_facts: false

  vars:

    prod_mgmt_network: "{{ ['server00'] | product(range(start,end)) | map('join') | list }}"
    start: 4281
    end: 4283

  tasks:

    - debug:
        var: prod_mgmt_network

命令示例

ansible-playbook --extra-vars hostName=server004181 test.yml

--extra-vars hostName我想要一个任务，如果值不是定义的变量之一，则执行将失败。
