Ansible register捕获命令输出

在playbook中可以使用register将捕获命令的输出保存在临时变量中，然后使用debug模块进行显示输出。

- name: var user
  hosts: dev
  vars:
    user: yaoyao
  tasks:
    - name: create var user
      user:
        name: "{{ user }}"
        state: present
      register: create_user

    - debug:
        var: create_user
