Question

我尝试运行我的Screen-shot of the error套件，但遇到了这个问题：

docker.errors.APIError：500服务器错误：内部服务器错误（＆＃34; b＆＃39; {＆＃34;消息＆＃34;：＆＃34;无法分配网关（10.49.0.201）：地址已经在使用＆＃34;}＆＃39;＆＃34;）

我尝试删除所有正在运行的容器和相关网络，但仍然遇到了问题。

的Env

内核

Docker env

在进行测试之前，我处于这种状态：

$ docker network ls
NETWORK ID          NAME                DRIVER              SCOPE
a4beb5d4de56        bridge              bridge              local

ed2452ee5e44        none                null                local

没有容器在运行 $ docker ps -a 集装箱ID图像命令创建状态端口名称

测试

def test_get_network_config(self):
    number_networks = len(self.docker_api.networks())
    network_config = container_services.get_network_config(
        data={
            'ip': '10.49.0.1',
            'subnet': '10.49.0.0/16',
            'gateway': '10.49.0.201',
            'vlan': 101
        },
        docker_client=self.docker_api
    )
    network_id = list(network_config.get('EndpointsConfig').keys())[0]

    self.assertEqual(number_networks + 1, len(self.docker_api.networks()))
    self.docker_api.remove_network(network_id)

代码

def get_network_config(data, docker_client):
    network = create_network(data, docker_client)
    network_name = docker_client.inspect_network(network.get('Id')).get('Name')
    network_info = dict()
    network_info[network_name] = docker_client.create_endpoint_config(ipv4_address=data.get('ip'))
    networking_config = docker_client.create_networking_config(network_info)
    return networking_config

错误
