인프런 커뮤니티 질문&답변

안녕하세요! 음 일단 에러메세지가 unknown error라서 저도 상당히 당황스러운데요

AWS 이슈로 생성이 되지 않는거일 수 있어서 30분즈음 뒤에 다시 시도해주시고 답글을 달아주세요!

기다리시는 동안 사용하시는 AWS 계정에 EC2 관련 권한들이 모두 있는지 한번 확인 부탁 드립니다

어케 하라는거죠..

Analysis

The instance failed to start due to an unknown error. This could be caused by a variety of factors, such as a temporary service disruption, resource constraints, or an issue with the instance configuration. You will need to review the instance details and logs to determine the root cause of the failure.

Resolution

Try the following steps to resolve your error:

1. Navigate to the EC2 dashboard in the AWS Management Console

2. Locate the failed instance launch attempt in the 'Instances' section

3. Review the instance details and configuration:

   • Check the instance type

   • Verify the AMI selection

   • Examine the network settings (VPC, subnet, security group)

   • Review any user data or advanced settings

4. Check the EC2 service health status in the AWS Service Health Dashboard for any ongoing issues in your region

5. Verify that you have not exceeded any service quotas:

   • Go to the Service Quotas console

   • Search for 'EC2' and review your current usage against the quotas

6. If the issue persists, create a new launch template:

   • In the EC2 console, go to 'Launch Templates'

   • Click 'Create launch template'

   • Configure the instance settings carefully

   • Use this new template to launch the instance

7. If the problem continues, try launching the instance in a different Availability Zone or region

8. Check CloudTrail logs for any relevant error messages or API calls related to the failed launch:

   • Go to the CloudTrail console

   • Look for events related to EC2 instance launches

9. If all else fails, contact AWS Support for further assistance:

   • Go to the AWS Support Center

   • Create a new case, providing details about the error and steps you've taken
