Elastic Beanstalk部署Docker容器启动后异常终止求助

各位技术同仁，我在将项目Docker镜像上传至Elastic Beanstalk平台时，遇到如下错误：

Instance deployment: The Docker container unexpectedly ended after it was started

我是相关技术的新手，无法定位问题原因，恳请各位提供帮助。以下是我的相关配置文件：

Dockerfile配置 #

WORKDIR /usr/src/app
COPY package*.json ./
RUN npm install --force
COPY . .
ENV APP_PORT 8080
EXPOSE 8080
CMD [ "node", "app.js" ]

.gitlab-ci.yml配置 #

  - build
  - run

    python zip.py ${APP_NAME}

    echo "Creating AWS Version Label"
    AWS_VERSION_LABEL=${APP_NAME}-${APP_VERSION}-${CI_PIPELINE_ID}
    S3_KEY="$AWS_VERSION_LABEL.zip"

    echo "Uploading to S3"
    aws s3 cp ${APP_NAME}.zip s3://${S3_BUCKET}/${S3_KEY} --region ${AWS_REGION}

    echo "Creating app version"
    aws elasticbeanstalk create-application-version \
      --application-name ${APP_NAME} \

    echo "Deploying app to tf test"

排查建议 #

• 本地验证Docker镜像：执行docker build -t my-app .构建镜像，再用docker run -p 8080:8080 my-app启动，检查容器是否能稳定运行，确认app.js无启动报错。
• 查看EB实例日志：在AWS控制台进入对应环境，下载完整日志包，重点查看/var/log/docker下的容器日志、/var/log/eb-engine.log里的部署细节，日志会明确容器终止的具体原因（比如依赖缺失、代码错误、端口占用）。
• 检查打包内容：确认zip.py打包的文件包含Dockerfile、app.js、package.json等所有必要文件，EB的Docker环境要求根目录存在Dockerfile才能正常构建。
• 验证环境变量：确认部署环境中已正确设置APP_ENVIROMENT_NAME变量，脚本依赖该变量指定部署目标环境。
• 检查IAM权限：确认用于部署的IAM用户拥有elasticbeanstalk:CreateApplicationVersion、s3:PutObject等必要操作权限。
