Question

我试图使用docker来运行我的jhipster微服务。

在没有Docker的情况下运行时我没有问题。但是现在我在尝试使用docker运行我的微服务时遇到了一些问题。

每次执行

docker-compose -f app.yml up

在我的UAA服务器上的

命令，它在运行UAA服务器时显示此错误。

这是我在Docker目录中的UAA服务器app.yml。

version: '2'
services:
uaa-app:
    image: uaa
    external_links:
        - uaa-mongodb:mongodb
        - jhipster-registry:registry
    environment:
        - SPRING_PROFILES_ACTIVE=dev,swagger
        - SPRING_CLOUD_CONFIG_URI=http://admin:admin@registry:8761/config
        - SPRING_DATA_MONGODB_URI=mongodb://mongodb:27017
        - SPRING_DATA_MONGODB_DATABASE=uaa
        - JHIPSTER_SLEEP=15 # gives time for the database to boot before the application 
uaa-mongodb:
    extends:
        file: mongodb.yml
        service: uaa-mongodb
jhipster-registry:
    extends:
        file: jhipster-registry.yml
        service: jhipster-registry
    environment:
        - SPRING_CLOUD_CONFIG_SERVER_NATIVE_SEARCH_LOCATIONS=file:./central-config/docker-config/

uaa-mongodb和jhipster-registry与docker配合得很好，但是我的UAA服务器无法连接到uaa-mongodb。

为什么错误一直说我使用localhost：27017甚至你试图在application-dev.yml中更改 SPRING_DATA_MONGODB_URI 和 spring.data.mongodb.uri 和application-prod.yml成差异值。

有人可以帮我解决这个问题......

Answer 1

回答我自己的问题，这就是我用我的剧本做的一切。

我将app.yml文件更改为

version: '2'
services:
    uaa:
        image: uaa:latest
        external_links:
            - uaa-mongodb:mongodb
            - jhipster-registry:registry
        links : 
            - uaa-mongodb:mongodb
        environment:
            - SPRING_PROFILES_ACTIVE=prod,swagger,test
            - SPRING_CLOUD_CONFIG_URI=http://admin:admin@registry:8761/config
            - EUREKA_CLIENT_SERVICEURL_DEFAULTZONE=http://admin:admin@registry:8761/config 
            - SPRING_DATA_MONGODB_HOST=mongodb
            - SPRING_DATA_MONGODB_PORT=27017
            - SPRING_DATA_MONGODB_DATABASE=uaa
            - JHIPSTER_SLEEP=15 # gives time for the database to boot before the application
    jhipster-registry:
        extends:
            file: jhipster-registry.yml
            service: jhipster-registry
        environment:
            - SPRING_CLOUD_CONFIG_SERVER_NATIVE_SEARCH_LOCATIONS=file:./central-config/docker-config/
    uaa-mongodb:
        extends:
            file: mongodb.yml
            service: uaa-mongodb

和我的application-pro.yml进入

eureka:
    instance:
        prefer-ip-address: true
    client:
        enabled: true
        healthcheck:
            enabled: true
        registerWithEureka: true
        fetchRegistry: true
        serviceUrl:
            defaultZone: ${EUREKA_CLIENT_SERVICEURL_DEFAULTZONE}

spring:
    devtools:
        restart:
            enabled: false
        livereload:
            enabled: false
    data:
        mongodb:
            host: ${SPRING_DATA_MONGODB_HOST}
            port: ${SPRING_DATA_MONGODB_PORT}
            database: ${SPRING_DATA_MONGODB_DATABASE}

现在我的UAA服务器成功连接到容器化的mongodb数据库。但现在我有了新的错误..
