是否可以从describe_instances（）输出创建EC2实例？

Question

Using python and BOTO3 service there is an option to use describe_instances() to get all the information about the running instances in specific region.

If I use that and save the output in JSON, later input that json and pass it to create_instances() , is it going to work or the format is different from what I need to pass to create_instnaces() function?

I'm asking that because I would like to make an automated option to get back a terminated instance which I have all its information saved.

thanks!

Answer 1

There is no standard format that would allow easy creation of a new instance from an existing or terminated instance.

You would need to take the output of describe_instances() and use it to call run_instances() .

Some information might no longer be available from a terminated instance, such as User Data.
