环境准备
pip install boto3
Alternatively, you can create the credential file yourself. By default, its location is at ~/.aws/credentials:
[default]
aws_access_key_id = YOUR_ACCESS_KEY
aws_secret_access_key = YOUR_SECRET_KEY
You may also want to set a default region. This can be done in the configuration file. By default, its location is at ~/.aws/config:
[default]
region=us-east-1
除了以上配置以外，还可以用环境变量，参数指定等等方式来配置验证

该脚本只需要把收集到的数据整理下，按自己需要的格式保存到CMDB中即可。
