boto3列出與ec2實例關聯的安全組

Question

是否可以通過boto3列出與EC2實例關聯的所有安全組？ 如果是這樣，如何完成？

我嘗試了以下方法，但是它們沒有按照我的意願進行操作：

for region in regions:
    client = boto3.client('ec2', region_name=region)
    try:
        payload = client.describe_security_groups(Filters=[{'Name': 'vpc-id', 'Values': ['vpc-*']}])
        for sg in payload["SecurityGroups"]:
            if sg["Description"] != "default VPC security group":
                resp = client.describe_security_group_references(DryRun=False, GroupId=[sg["GroupId"]])
                print resp

    except Exception as E:
        print region, E
        continue

for region in regions:
    client = boto3.client('ec2', region_name=region)
    try:
        payload = client.describe_security_groups(Filters=[{'Name': 'vpc-id', 'Values': ['vpc-*']}])
        for sg in payload["SecurityGroups"]:
            if sg["Description"] != "default VPC security group":
                sg = json.dumps(sg)
                pp(sg)
                # x = requests.post(url=sumocollector, data=sg)
                # print x.status_code

    except Exception as E:
        print region, E
        continue

如果您正在尋找每個實例的SG列表，則可以使用describe_instances代替：

for region in regions:
    client = boto3.client('ec2', region_name=region)
    try:
        response = client.describe_instances()
        for reservation in response['Reservations']:
            for instance in reservation['Instances']:
                print("Instance: " + instance['InstanceId'])
                for securityGroup in instance['SecurityGroups']:
                    print("SG ID: {}, Name: {}".format(securityGroup['GroupId'], securityGroup['GroupName']))

    except Exception as E:
        print(region, E)
        continue
