,可以通过以下步骤实现:
- name: Set user variable based on ec2 distribution
hosts: all
gather_facts: true
tasks:
- name: Get ec2 instance info
ec2_instance_info:
aws_access_key: YOUR_AWS_ACCESS_KEY
aws_secret_key: YOUR_AWS_SECRET_KEY
region: YOUR_AWS_REGION
instance_id: YOUR_EC2_INSTANCE_ID
metadata_options:
http_tokens: required
register: ec2_info
- name: Set user variable based on ec2 distribution
set_fact:
user_variable: "{{ 'value_for_amazon_linux' if ec2_info.instances[0].distribution == 'Amazon' else 'value_for_ubuntu' }}"
- name: Print user variable
debug:
var: user_variable
在上述示例中,根据ec2实例的发行版,设置了一个名为"user_variable"的用户变量。如果发行版是Amazon Linux,则"user_variable"的值为"value_for_amazon_linux";如果发行版是Ubuntu,则"user_variable"的值为"value_for_ubuntu"。
请注意,上述示例中的YOUR_AWS_ACCESS_KEY、YOUR_AWS_SECRET_KEY、YOUR_AWS_REGION和YOUR_EC2_INSTANCE_ID需要替换为实际的AWS访问密钥、区域和ec2实例ID。
