我正在使用Ansible剧本创建Ec2实例。这里我需要捕获创建的EC2实例id、IPv4等的输出。那么如何在命令提示符中获取返回值，以及如何将这些值分配给一个变量。
如β.εηιτ.βε所述，在您的情况下，注册变量可能会有所帮助
这是我的测试手册：
- hosts: localhost
gather_facts: false
vars:
ansible_python_interpreter: /usr/bin/python3
tasks:
- name: Launch ec2 instance
amazon.aws.ec2_instance:
region: us-east-2
key_name: khaled
security_group: launch-wizard-1
instance_type: t2.micro
image_id: ami-xxxxxxxxxxxxxxxxx
wait: yes
wait_timeout: 500
tags:
name: appservers
os: ubuntu
vpc_subnet_id: subnet-xxxxxxxx
network:
assign_public_ip: true
delete_on_termination: true
aws_access_key: "{{ aws_access_key|default(lookup('env', 'AWS_ACCESS_KEY')) }}"
aws_secret_key: "{{ aws_secret_key|default(lookup('env', 'AWS_SECRET_KEY')) }}"
register: ec2
delegate_to: localhost
- debug:
msg: "{{ ec2 }}"
输出如下：

然后，您可以指示所需的任何值，并将其分配给变量：
- name: Set ec2 facts
set_fact:
ec2inf: "{{ ec2.instances[0].instance_id }},{{ ec2.instances[0].public_ip_address }}"
- debug:
msg: "{{ ec2inf }}"

"msg": "i-xxxxxxxxxxxxxx574,1x.1xx.xxx.205"
}
