無法在docker-compose中使用mysql容器和flyway連接docker Spring-Boot應用程序

Question

我有一個與mysql連接的spring-boot服務。 當我使用maven和mysql的docker容器運行應用程序時，應用程序設置正常。

現在我想用docker運行應用程序，所以我使用docker-compose來引導mysql和我的服務作為容器。

但我不工作，我的服務無法連接到mysql，發生以下異常：

似乎Flyway數據庫遷移存在問題......

現在，當我的服務容器退出並使用CTRL-C退出docker-compose並使用docker-compose重新啟動時，一切正常，我的servive和mysql啟動並且flyway遷移按預期發生。

有沒有人有想法？ 它對我來說沒問題，因為我知道第二次啟動時一切都會好起來，但我真的不知道為什么會出現這個錯誤，這真的很煩人......

這是我的配置，縮寫為：

flyway:
    enabled: true

spring.datasource:
    url: jdbc:mysql://localhost:3306/dbaccounts
    username: root
    password: root
    driver-class-name: com.mysql.jdbc.Driver

spring.jpa:
    database-platform: org.hibernate.dialect.MySQL5Dialect
    show-sql: true
    generate-ddl: false
    hibernate:
      ddl-auto: validate

還有我的docker-compose.yml：

mysqlaccounts:
  image: mysql:5.6
  ports:
    - 3306:3306
  environment:
    MYSQL_USER: root
    MYSQL_ROOT_PASSWORD: root
    MYSQL_DATABASE: dbaccounts

accountservice:
  image: account-service
  ports:
    - 8081:8081
  links:
    - mysqlaccounts
  environment:
    - SPRING_DATASOURCE_URL=jdbc:mysql://mysqlaccounts:3306/dbaccounts
    - SPRING_DATASOURCE_USERNAME=root
    - SPRING_DATASOURCE_PASSWORD=root

當我從頭開始禁用飛路時，一切都很好......

提前感謝任何想法和建議..;）

PS：我使用的是Ubuntu 15.10，Java8，spring-boot 1.3.RELEASE和Docker 1.9.0以及docker-compose版本：1.5.1。

您應該將datasource url的主機替換為docker-machine的ip。 它看起來像：

jdbc:mysql://192.168.99.100/dbaccounts
