[AWS][Codedeploy] missing credentials - please check if this instance was started with an iam instance profile

Codedeploy를 이용하여 EC2에 배포를 시도했는데,

Codedeploy 콘솔에서 

 

CodeDeploy agent was not able to receive the lifecycle event. Check the CodeDeploy agent logs on your host and make sure the agent is running and can connect to the CodeDeploy server. 

codedeploy 에러메세지

 

 

EC2에서 에러 로그를 확인해야할 것 같아서 로그를 확인해보았다.

tail -F /var/log/aws/codedeploy-agent/codedeploy-agent.log

missing credentials - please check if this instance was started with an iam instance profile

 

내가 무언가 잘못했나? 싶었는데...어이없게도 codedeploy agent를 재시작하니 해결되었다😵

 

 

해결방법

sudo service codedeploy-agent restart
