Docker gremlin-server：“无法分配请求的地址”

Question

我对Docker有点新手，所以如果这是显而易见的，请原谅我。

我有两个码头集装箱，我想和他们谈谈。一种是开箱即用地运行gremlin-server实例。我是从命令docker run --name="gremlin-server" -p 8182:8182 tinkerpop/gremlin-server开始的

另一个是使用lambci运行一个lambda函数。要运行我的基本测试函数，我使用命令docker run --rm -v "$PWD"/lambda:/var/task -v "$PWD"/layer:/opt lambci/lambda:python3.6 test_containers.lambda_handler

下面是我的test_containers.py代码：

from gremlin_python.driver.driver_remote_connection import DriverRemoteConnection
from gremlin_python.process.anonymous_traversal import traversal


def lambda_handler(event, context):
    gremlin_url = 'ws://localhost:8182/gremlin'
    g = traversal().withRemote(DriverRemoteConnection(gremlin_url, 'g'))

下面是我从lambda函数返回的错误：

{
   "errorMessage":"[Errno 99] Cannot assign requested address",
   "errorType":"OSError",
   "stackTrace":[
      [
         "/var/task/test_containers.py",
         7,
         "lambda_handler",
         "g = traversal().withRemote(DriverRemoteConnection(gremlin_url, 'g'))"
      ],
      [
         "/opt/python/lib/python3.6/site-packages/gremlin_python/driver/driver_remote_connection.py",
         45,
         "__init__",
         "password=password)"
      ],
      [
         "/opt/python/lib/python3.6/site-packages/gremlin_python/driver/client.py",
         76,
         "__init__",
         "self._fill_pool()"
      ],
      [
         "/opt/python/lib/python3.6/site-packages/gremlin_python/driver/client.py",
         92,
         "_fill_pool",
         "conn = self._get_connection()"
      ],
      [
         "/opt/python/lib/python3.6/site-packages/gremlin_python/driver/client.py",
         105,
         "_get_connection",
         "self._transport_factory, self._executor, self._pool)"
      ],
      [
         "/opt/python/lib/python3.6/site-packages/gremlin_python/driver/connection.py",
         40,
         "__init__",
         "self.connect()"
      ],
      [
         "/opt/python/lib/python3.6/site-packages/gremlin_python/driver/connection.py",
         46,
         "connect",
         "self._transport.connect(self._url)"
      ],
      [
         "/opt/python/lib/python3.6/site-packages/gremlin_python/driver/tornado/transport.py",
         33,
         "connect",
         "lambda: websocket.websocket_connect(url))"
      ],
      [
         "/opt/python/lib/python3.6/site-packages/tornado/ioloop.py",
         458,
         "run_sync",
         "return future_cell[0].result()"
      ],
      [
         "/opt/python/lib/python3.6/site-packages/tornado/concurrent.py",
         238,
         "result",
         "raise_exc_info(self._exc_info)"
      ],
      [
         "<string>",
         4,
         "raise_exc_info",
         ""
      ],
      [
         "/opt/python/lib/python3.6/site-packages/tornado/iostream.py",
         1117,
         "connect",
         "self.socket.connect(address)"
      ]
   ]
}

所以我不确定a.我是否使用了正确的url来访问服务器，b.我需要做更多的设置才能让他们说话。

我在windows上运行docker。我可以设置一个ubuntu虚拟机来运行它们，但这似乎...多余的。任何帮助都是非常感谢的。

不是gremlin_url = 'ws://localhost:8182/gremlin‘，而是gremlin_url = 'ws://host.docker.internal:8182/gremlin’或您的docker容器主机名。
