將 MongoDB 羅盤客戶端連接到 kubernetes 集群內的 mongodb 數據庫

Question

我在 kubernetes 集群內運行 mongo docker 容器服務。 來自外部的傳入流量通過 ingress-nginx ( https://kubernetes.github.io/ingress-nginx/ ) 負載均衡器路由到 mongo Z05B6053C41A2130AFD6FC3BE158 容器服務。

應用程序按預期工作，我需要知道是否有一種方法可以將 MongoDB 羅盤客戶端（我安裝在本地機器上）連接到正在運行的 mongodb 容器以輕松可視化數據。

我遇到了問題，因為容器在 kubernetes 內部，並且中間有一個負載均衡器。

如果有人可以提供幫助，將會有很大幫助。 謝謝

您可以使用端口轉發

$ kubectl port-forward -h
Forward one or more local ports to a pod. This command requires the node to have 'socat' installed.

 Use resource type/name such as deployment/mydeployment to select a pod. Resource type defaults to 'pod' if omitted.

 If there are multiple pods matching the criteria, a pod will be selected automatically. The forwarding session ends
when the selected pod terminates, and rerun of the command is needed to resume forwarding.

Examples:
  # Listen on ports 5000 and 6000 locally, forwarding data to/from ports 5000 and 6000 in the pod
  kubectl port-forward pod/mypod 5000 6000

  # Listen on ports 5000 and 6000 locally, forwarding data to/from ports 5000 and 6000 in a pod selected by the
deployment
  kubectl port-forward deployment/mydeployment 5000 6000

  # Listen on ports 5000 and 6000 locally, forwarding data to/from ports 5000 and 6000 in a pod selected by the service
  kubectl port-forward service/myservice 5000 6000

  # Listen on port 8888 locally, forwarding to 5000 in the pod
  kubectl port-forward pod/mypod 8888:5000

  # Listen on port 8888 on all addresses, forwarding to 5000 in the pod
  kubectl port-forward --address 0.0.0.0 pod/mypod 8888:5000

  # Listen on port 8888 on localhost and selected IP, forwarding to 5000 in the pod
  kubectl port-forward --address localhost,10.19.21.23 pod/mypod 8888:5000

  # Listen on a random port locally, forwarding to 5000 in the pod
  kubectl port-forward pod/mypod :5000

Options:
      --address=[localhost]: Addresses to listen on (comma separated). Only accepts IP addresses or localhost as a
value. When localhost is supplied, kubectl will try to bind on both 127.0.0.1 and ::1 and will fail if neither of these
addresses are available to bind.
      --pod-running-timeout=1m0s: The length of time (like 5s, 2m, or 3h, higher than zero) to wait until at least one
pod is running

Usage:
  kubectl port-forward TYPE/NAME [options] [LOCAL_PORT:]REMOTE_PORT [...[LOCAL_PORT_N:]REMOTE_PORT_N]

Use "kubectl options" for a list of global command-line options (applies to all commands).
