【问题描述】：

我正在尝试启动一个运行多容器 Docker 的 AWS BeanStalk 环境，但它失败并出现以下事件列表：

【问题讨论】：

您是否在应用程序中设置了健康检查端点？：docs.aws.amazon.com/elasticbeanstalk/latest/dg/…

我没有。我刚刚意识到我没有按照文档docs.aws.amazon.com/elasticbeanstalk/latest/dg/…

中的描述配置角色和权限

【参考方案1】：

@Kilinc：如果您使用多 docker 容器平台创建弹性 beanstalk 应用程序，则必须将以下策略列表添加到默认角色“aws-elasticbeanstalk-ec2-role”，或者您可以创建自己的角色。

AWSElasticBeanstalkWebTier AWSElasticBeanstalkMulticontainerDocker AWSElasticBeanstalkWorkerTier

谢谢

【参考方案2】：

我似乎忘记按照 AWS BeanStalk 文档中的说明设置策略和权限： http://docs.aws.amazon.com/elasticbeanstalk/latest/dg/create_deploy_docker_ecstutorial.html

【讨论】：

你能解释一下你必须做什么才能让它工作吗？
