python - Boto3:如何获取从 Spot 请求创建的实例 ID？

Question

发送 Spot 请求并等待 Spot 请求得到满足似乎可行。

接下来，如何获取为检查而创建的 ec2 实例 ID/对象，例如IP地址等？

这是我到目前为止的代码:

def create_spot_instance():
    print("Send Spot Request")
    ec2_client = boto3.client('ec2')
    res = ec2_client.request_spot_instances(
        ...
    )
    request_id = res['SpotInstanceRequests'][0]['SpotInstanceRequestId']
    print("Wait for request to be fulfilled...")
    waiter = ec2_client.get_waiter('spot_instance_request_fulfilled')
    waiter.wait(SpotInstanceRequestIds=[request_id])
    print("Wait for ec2 instance to boot up...")
    # TODO: get instance id the spot instance created
    # TODO: wait until spot instance is booted up
    # TODO: return object of ec2 instance

Answer 1

describe_spot_instance_requests 应该给出由 spot 创建的实例 ID。
