AWS Elastic Beanstalk部署Docker容器健康转严重及ELB异常求助

问题概述 #

将Docker容器部署至AWS Elastic Beanstalk后，环境初始化完成后健康状态从正常转为严重，所有实例的ELB健康检查失败或不可用。本地Docker镜像运行正常，仅在AWS环境中出现问题。已删除本地所有镜像和容器并重新创建环境，问题仍未解决。

.elasticbeanstalk配置 #

branch-defaults:
  default:
    environment: Sentiment-App-env
    group_suffix: null
global:
  application_name: Sentiment-App
  branch: null
  default_ec2_keyname: null
  default_platform: Docker
  default_region: eu-west-3
  include_git_submodules: true
  instance_profile: null
  platform_name: null
  platform_version: null
  profile: eb-cli
  repository: null
  sc: null
  workspace_type: Application

访问测试结果 #

通过环境访问链接调用接口时，执行以下代码出现异常：

text = {"text" : "Hello how are you"}

response = requests.post(url, json=text)

response.json

移除.json后得到输出：

<Response [503]>

使用的Elastic Beanstalk CLI命令 #

• eb init -p docker Sentiment-App
• eb local run --port 5000
• eb create Sentiment-App-env

曾怀疑本地Docker镜像导致问题，清理镜像时日志显示：
