Ansible 多个主机在一个角色中

随着脚本的进行，如何编写单个角色并连接到不同的主机？

这是我想做的一个例子，但我收到一个错误，如下所示。

ERROR! no action detected in task. This often indicates a misspelled module name, or incorrect module path.

The error appears to be in '/etc/ansible/roles/customer_setups/microlight/customer_app_template/tasks/main.yml': line 3, column 3, but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:

# tasks file for /etc/ansible/roles/customer_app_template
- hosts: synbill-apps
  ^ here
