Springboot mongo 異常與 Docker

Question

我是 docker 的新手，並嘗試將 spring 啟動應用程序與在 docker 上運行的 mongo db 連接，我在端口 27017 有：

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-mongodb</artifactId>
        </dependency>

我沒有在 application.properties 中指定任何內容。 以下是 spring 啟動失敗的日志：

com.mongodb.MongoSocketOpenException: Exception opening socket
    at com.mongodb.internal.connection.SocketStream.open(SocketStream.java:67) ~[mongodb-driver-core-3.8.2.jar:na]

以及來自 mongodb(docker) 的日志

有人可以幫我嗎？

謝謝！

上述問題的解決方案：-

By getting the Windows 2004 version upgrade and then installing Docker Desktop for Windows(after uninstalling the Docker Toolbox legacy one, which was required for previous windows versions).

---

我建議您通過docker-compose運行您的容器，並檢查下面的docker-compose.yml以供參考。

version: "3"
services:
  api-database:
    image: mongo:3.2.4
    container_name: "api-database"
    ports:
      - 27017:27017
    command: --smallfiles
  api:
    image: XXXX
    ports:
      - XXXX:XXXX
    links:
      - api-database

使用 docker-compose 中定義的服務名稱使用 spring 配置屬性配置 mongodb 主機名。

spring.data.mongodb.host=api-database

然后運行

docker-compose up
