尽管使用了 set_fact 和 HostVars，但无法从另一个播放中获取变量

问：

我无法从其他主机读取内容。set_fact

我的 ansible 版本是 2.8.4

以下是我的剧本：

[wladmin@ansiblehost ~]$ cat getvar.yml
 
---
- name: "Play 1"

  hosts: localhost
  any_errors_fatal: True
  serial: 1
  gather_facts: no

  tasks:

   - add_host:
       name: "sourcehost"
       groups: source_node
       ansible_user: "linuxuser"

   - add_host:
       name: "desthost"
       groups: "dest_node"
       ansible_user: "linuxuser"
 

- name: "Gather facts from source_node"
  hosts: source_node

  tasks:

    - name: Set copyuser variable on source_node
      set_fact:
        copyuser: "HELLO"

- name: "Configure Destination node {{ dest_node }}"

  hosts: dest_node
  any_errors_fatal: True
  gather_facts: false
  serial: 1

  tasks:

    - debug:
        msg: "The value of copyuser from source_node is {{ hostvars['source_node']['copyuser'] }}"

错误输出在这里：

[wladmin@ansiblehost ~]$ ansible-playbook getvar.yml
