com.mongodb.MongoSocketOpenException:异常打开套接字(MongoDB,Docker)

Question

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."

我用execute命令启动我的应用程序:docker-compose up --build

Docker日志:

application.yml:

# Spring properties
spring:
  application:
    name: car-service
  data:
    mongodb.host: localhost
    mongodb.port: 32769

    mongo.repositories.enabled: true

为什么我打开套接字有异常？如何解决这个问题？

Answer 1

您将属性文件中的mongodb主机设置为localhost.在容器本地主机地址本身,但您的mongodb 不在该汽车服务运行的容器(汽车服务)中.当您使用docker compose时,您可以使用其名称来寻址容器.在你的情况下,它是mongodb.

澄清@barbakini 的答案，在applications.yaml 中定义它使用：

spring.data.mongodb.host: mongodb
