我尝试使用docker image启动我的应用程序(Spring Boot + Spring Cloud + Eureka + MongoDB),但我无法连接到MongoDB。
例外:
exception "com.mongodb.MongoSocketOpenException: Exception opening socket."
我使用执行命令启动我的应用程序: docker-compose up --build

为什么我打开套接字有异常?如何解决这个问题?

您正在将属性文件中的mongodb主机设置为 localhost 。在容器本地主机地址本身中,但您的mongodb在该容器(汽车服务)中不哪个汽车服务运行。当您使用docker compose时,您可以使用其名称寻址容器。在你的情况下,它是 mongodb 。

阐明@barbakini的答案,在application.yaml中定义它,请使用:
spring.data.mongodb.host: mongodb
答案 2 :(得分:0)
您的mongoDB服务未启动
通过以下命令检查状态
sudo service mongodb status
sudo service mongodb start
希望它能正常工作,可能还有几个原因, 例如您在应用程序中为mongodb服务定义的配置不正确,例如port。

尝试添加
network_mode: host
并删除
links: ....
对于想要与mongo或eureka或postgresql连接的所有服务,都在docker-compose.yml中。
这样,您将连接到docker localhost。
