我正在使用Ansible自动化EC2实例。我创建了EC2实例,然后尝试通过ec2_remote_facts模块获取其公共DNS名称。但输出中显示变量未定义。
playbook:
- hosts: localhost
connection: local
tasks:
- name: ec2 instance facts
ec2_remote_facts:
region: ap-southeast-2
filters:
instance-state-name: running
register: ec2
- debug: var=ec2.instances.public_name
Output:PLAY [localhost] ***************************************************************
TASK [setup] *******************************************************************
ok: [localhost]
TASK [create ec2 instance] *****************************************************
ok: [localhost]
TASK [debug] *******************************************************************
ok: [localhost] => {
"ec2.instances.public_name": "VARIABLE IS NOT DEFINED!"
}
PLAY RECAP *********************************************************************
localhost : ok=3 changed=0 unreachable=0 failed=0
Output for ec2.instances.

我在这里错过了什么?
谢谢
