你能帮我吗。我尝试在 ubuntu 服务器上部署应用程序。我使用 docker-compose up。我有这个错误。

Answer 1

在您的 docker-compose.yml 中，您仅将 spring boot 应用程序与您的 mongodb 链接起来。

在您的application.properties 中，您正在使用不是有效主机的 mongodb。

您需要为您的 spring 应用程序传递环境变量。为此，您可以在 docker-compose.yml 中执行类似的操作。

version: "3"
services:
  mymongodb:
    image: mongo:latest
    container_name: "mymongodb"
    ports:
      - 27017:27017
  spring-mongo:
    image: spring-mongo:1.0
    container_name: spring-mongo
    ports:
      - 8080:8080
    environment:
      - MONGO_HOST=mymongodb
    links:
      - mymongodb

并且在您的application.properties中，

spring.data.mongodb.host=${MONGO_HOST}
