在 Docker + WSL 版本 2 中連接 ECONNREFUSED 127.0.0.1:27017 Mongo

Question

我正在使用的堆棧：

WSL v2：

  NAME            STATE           VERSION
* Ubuntu-18.04    Running         2
  Ubuntu-20.04    Stopped         2

WSL 中的 Docker：

MongoDB 4.0.8

對於 MongoDB，我使用的是官方圖片：

plonca@KAT-IT-1012:~$ docker run -d -p 27017-27019:27017-27019 --name mongodb_408 mongo:4.0.8

我可以登錄容器並檢查 mongo 是否正在運行並且可以訪問：

plonca@KAT-IT-1012:~$ docker exec -it mongodb_408  bash
root@5b622e89bfef:/# mongo
MongoDB shell version v4.0.8
connecting to: mongodb://127.0.0.1:27017/?gssapiServiceName=mongodb
Implicit session: session { "id" : UUID("0ae27473-4cc7-4d0d-9976-c922ea58b936") }
MongoDB server version: 4.0.8

Enable MongoDB's free cloud-based monitoring service, which will then receive and display
metrics about your deployment (disk utilization, CPU, operation statistics, etc).

The monitoring data will be available on a MongoDB website with a unique URL accessible to you
and anyone you share the URL with. MongoDB may use this information to make product
improvements and to suggest MongoDB products and deployment options to you.

To enable free monitoring, run the following command: db.enableFreeMonitoring()
To permanently disable this reminder, run the following command: db.disableFreeMonitoring()

Docker 似乎正在監聽端口 27017：

plonca@KAT-IT-1012:~$ sudo netstat -tulpn | grep :27017
tcp6       0      0 :::27017                :::*                    LISTEN      2114/docker-proxy

但是，在嘗試從 Mongo Compass（安裝在 Windows 上）連接到mongodb://127.0.0.1:27017時，出現此錯誤：
