疑惑:如何使用多个vCenter？

Question

我使用Ansible在VMware vCenter中拍摄VM的快照。

如果vcenter只有一个，那么它可以正常工作，但如果有多个vcenter呢？

如何描述当前角色中的多个Vmware vCenter？

我当前针对一个vcenter的示例：

cat snapshot.yml

- name: ROLE_update
   hosts: all
   gather_facts: False
   become: yes
   become_method: su
   become_user: root
   vars_files:
     -  /ansible/vars/privileges.txt
   roles:
    - role: snapshot

cat任务/main.yml

- block:
    - name: "Create vmware snapshot of {{ inventory_hostname }}"
      vmware_guest_snapshot:
        hostname: "{{vcenter_hostname }}"
        username: "{{ vcenter_username }}"
        password: "{{ vcenter_password }}"
        datacenter: "{{datacenter_name}}"
        folder: find_folder.yml
        name: "{{inventory_hostname }}"
        state: present
        snapshot_name: snap check
        validate_certs: False
      delegate_to: localhost
      register: vm_facts

cat find_folder.yml

- name: Find folder path of an existing virtual machine
  hosts: all
  gather_facts: False
  vars:
    ansible_python_interpreter: "/usr/bin/env python3"
  tasks:

    - name: "Find folder for VM - {{ vm_name }}"
      vmware_guest_find:
        hostname: "{{ vcenter_hostname }}"
        username: "{{ vcenter_username }}"
        password: "{{ vcenter_password }}"
        datacenter: "{{ datacenter_name }}"
        validate_certs: False
        name: "{{ vm_name }}"
      delegate_to: localhost
      register: vm_facts

声明的cat vars/main.yml变量

vcenter_hostname: <secret>
vcenter_username: <secret>
vcenter_password: <secret>

谢谢!

将不同vcenter的变量放在不同的".yml“文件中是一种选择吗？如果是这样，您可以很容易地在运行时执行时调用这些变量，如下所示：

ansible-playbook your_playbook.yml --extra-vars "your_vcenter_1.yml"

我还可以想到其他方法，比如在playbook中为每个任务使用标记，并使用特定的标记调用playbook。对于每个具有不同标记的任务，在import_role上，您可以像这样定义新变量：

tasks:
- import_tasks: your_role.yml
  vars:
   vcenter_hostname: your_vcenter_1
  tags:
    - vcenter1
