無法從 Elastic Beanstalk Docker 連接到 RDS

Question

我在 Elastic Beanstalks docker 中部署的 Spring Boot 應用程序無法連接到外部 RDS。 在應用程序啟動期間，它總是停留在“com.zaxxer.hikari.HikariDataSource - HikariPool-1 - 正在啟動...”。

Dockerfile （我在 ENTRYPOINT 中添加了數據庫連接詳細信息以進行故障排除）

    FROM openjdk:8
    WORKDIR "/mrbs"
    ARG JAR_FILE=target/*jar
    COPY ${JAR_FILE} ./app.jar
    EXPOSE 8080
    #CMD ["java","-jar","./app.jar"]
    ENTRYPOINT ["java","-jar","./app.jar","--spring.datasource.url=jdbc:mysql://[security].[security].ap-southeast-1.rds.amazonaws.com:3306/mrbs?serverTimezone=GMT%2B8","--spring.datasource.password=[security]","--spring.datasource.username=[security]","--logging.file.path=/mrbs/logs/"]

Dockerrun.aws.json

    {
      "AWSEBDockerrunVersion": 2,
      "containerDefinitions": [
        {
          "name": "api",
          "image": "[security]/mrbs-backend",
          "hostname": "api",
          "essential": true,
          "memory": 128
        }
      ]
    }

.travis.yml

    language: generic
    sudo: required
    services:
      - docker
    before_install:
    install: skip
    before_script:
    script:
      - mvn -f mrbs-backend clean package
      - docker build -t [security]/mrbs-backend ./mrbs-backend
      - echo "$DOCKER_PASSWORD" |docker login -u "$DOKCER_ID" --password-stdin
      - docker push [security]/mrbs-backend
    
    deploy:
      skip_cleanup: true
      provider: elasticbeanstalk
      region: ap-southeast-1
      #app: mrbs-docker
      app: mrbs
      env: Mrbs-env-3
      bucket_name: elasticbeanstalk-ap-southeast-1-[security]351
      bucket_patch: mrbs
      on:
        branch: master
      access_key_id: $AWS_ACCESS_KEY
      secret_access_key: $AWS_SECRET_KEY

向 RDS 和 Elastic Beanstalk RDS 安全組（圖像）、 Elastic Beanstalk 安全組（圖像）、 EC2 安全組（圖像）添加了安全組mrbs-intra-docker ，

當我檢查彈性 beanstalk 的日志時，它顯示 spring boot 應用程序在啟動期間卡在“com.zaxxer.hikari.HikariDataSource - HikariPool-1 - 正在啟動...”。

但是，如果我直接從 EC2 命令行運行 docker，則可以成功啟動 spring boot，這意味着 ec2 實例可以使用相同的映像連接到 rds...

Answer 1

根據評論。

該問題是由於分配給容器的內存不足造成的。

解決方案是增加內存。
