使用 JupyterHub 身份验证连接到 dask 网关服务器失败

Question

我正在使用 DaskGateway 服务器使用 DaskHub 和 JupyterHub 进行多用户设置，但我与 dask-gateway 服务器的连接失败并出现错误：

错误

ClientConnectorError: Cannot connect to host traefik-dask-gateway:80 ssl:default [Name or service not known]

使用的连接字符串：

from dask_gateway import Gateway
gateway = Gateway(
    address="http://traefik-dask-gateway/services/dask-gateway/",
    public_address="https://jupyter-hub01.devops.h2.theagilehub.net/services/dask-gateway/",
    auth="jupyterhub")
gateway.list_clusters()

Helm 图表配置值：

jupyterhub:
  proxy:
    secretToken: "<token1>"
  hub:
    services:
      dask-gateway:
        apiToken: "<token2>"
    networkPolicy:
      enabled: false
  ingress:
    enabled: true
    ingressClassName: pomerium

        hosts:

    hosts:

      ingress.pomerium.io/preserve_host_header: 'true'
      ingress.pomerium.io/policy: |
        [{
          "allow": {
            "or": [
              {"claim/cognito:groups": "eu-west-1_ryHLiyRp9_shell-dev"}
            ]
          }
          }]
dask-gateway:
  gateway:
    auth:
      type: jupyterhub
      jupyterhub:
        apiToken: "<token2>"

有人可以帮我吗？
