Question

当我运行我的代码时，我得到了这个，我创建了一个带有两个子网的VPC，并且在2个实例中但在同一个子网内。当我尝试将子网发送到实例时出现我的问题我收到此错误，并且您可以在第一个屏幕上看到，使子网的名称和每个显示的ID分配ID

这是我运行的代码的一部分：

bastion_hosts = [] 
    for instancia in vpc_config.sections():
        if (instancia != 'vpc' ) and (instancia != 'sub-sas1' ) and ( instancia != 'sub-sas2'):
            cidr_block = vpc_config.get(instancia, 'cidr_block')
            bastion_host_name = vpc_config.get(instancia, 'bastion_host')
            instance_type = vpc_config.get(instancia,'default_instance_type')
            availability_zone = vpc_config.get(instancia, 'availability_zone')
            bastion = get_or_create_bastion_host(conn, vpc_config, bastion_host_name, vpc, Subnet[0])
            bastion_hosts.append(bastion)
            print bastion_hosts

    return bastion_hosts

其中堡垒由：

定义

def get_or_create_bastion_host(conn, vpc_config, bastion_host_name, vpc, subnet):
    image_id = vpc_config.get('vpc', 'default_image_id')
    image_login_user = vpc_config.get('vpc', 'default_image_login_user')
    instance_type = vpc_config.get('vpc','default_instance_type')
    key_pair = get_bastion_host_key(conn, vpc_config)
    security_group = get_or_create_vpc_security_group(conn, vpc_config, vpc.id)

    for reservation in fetch_running_reservations(conn, bastion_host_name, vpc.id):
        for instance in reservation.instances:
            public_ip = associate_elastic_ip(conn, instance)
            return Node(bastion_host_name, public_ip, image_login_user, BASTION_KEY_FILE)

    print 'Creating Instance with name:', bastion_host_name
    reservation = conn.ec2.run_instances(image_id, instance_type=instance_type,
                                         security_group_ids=[security_group.id],
                                         key_name=key_pair.name, subnet= Subnet[0])

    for instance in reservation.instances:
        print 'Waiting for', bastion_host_name, instance.id, 'to start ...'
        wait_until(instance, 'running')
        tag_with_name(instance, bastion_host_name)
        public_ip = associate_elastic_ip(conn, instance)
        print bastion_host_name, 'is associated with Elastic IP', public_ip
        return Node(bastion_host_name, public_ip, image_login_user, BASTION_KEY_FILE)

任何帮助??

当范围中没有定义此类变量时，您正尝试使用Subnet[0]。由于您将subnet传递给get_or_create_bastion_host，因此您应使用subnet代替Subnet[0]。

get_or_create_bastion_host（conn，vpc_config，bastion_host_name，vpc，子网）

要使其有效，请尝试将传递的subnet分配给参数subnet：

reservation = conn.ec2.run_instances(image_id, instance_type=instance_type,
                                     security_group_ids=[security_group.id],
                                     key_name=key_pair.name, subnet_id=subnet)
