我有一个ec2实例运行在ubuntu服务器上，我正试图实现CI/CD流使用codedeploy和源是位桶。我还在ec2实例上安装了codedeploy-agent，它已安装并成功运行，但每当我在ec2上部署代码时，部署失败，出现以下错误:
The overall deployment failed because too many individual instances failed deployment, too few
healthy instances are available for deployment, or some instances in your deployment group are
experiencing problems.
在我使用less /var/log/aws/codedeploy-agent/codedeploy-agent.log访问的CodeDeploy代理日志文件中显示以下错误:
ERROR [codedeploy-agent(31598)]: InstanceAgent::Plugins::CodeDeployPlugin::CommandPoller:
Missing credentials - please check if this instance was started with an IAM instance profile
我不明白我怎么才能克服这个错误，有人告诉我。
CodeDeploy代理需要实例的IAM角色/配置文件提供的IAM权限。所需的确切权限在AWS文档中给出:
