AWS CLI를 사용하여 Amazon EC2 인스턴스 리스트 출력

AWS CLI를 사용하여 Amazon EC2 인스턴스 리스트 출력(aws ec2 describe-instances)

태그 입력 전 - 출력

aws --region ap-northeast-2 ec2 describe-instances \
--query 'Reservations[*].Instances[*].[Tags[0].Value, \
PrivateIpAddress, State.Name, InstanceType, InstanceId, Placement.AvailabilityZone]' \
--output=table

• ec2 describe-instances : EC2 인스턴스의 상세 정보를 가져오는 명령입니다.
• --region ap-northeast-2 : 명령이 실행될 리전을 지정합니다. 여기서는 서울 리전(ap-northeast-2)으로 지정되어 있습니다.
• --query 'Reservations[*].Instances[*].[Tags[0].Value, PrivateIpAddress, State.Name, InstanceType, InstanceId, Placement.AvailabilityZone]' : --query 옵션을 사용하여 출력 형식을 지정합니다. 여기서는 테이블 형식으로 원하는 속성을 선택하여 출력합니다.
• --output=table : 결과를 테이블 형식으로 출력하도록 지정합니다.

$ aws --region ap-northeast-2 ec2 describe-instances \
--query 'Reservations[*].Instances[*].[Tags[0].Value, \
PrivateIpAddress, State.Name, InstanceType, InstanceId, Placement.AvailabilityZone]' \
--output=table

태그 입력 후 - 출력

: 태그 입력 후 호스명 필드에 태그에 첫 번째 값을 가져와서 tag name으로 호스트명을 출력함

aws --region ap-northeast-2 ec2 describe-instances \
--query 'Reservations[*].Instances[*].[join(`,`,Tags[?Key==`Name`].Value), \
PrivateIpAddress, State.Name, InstanceType, InstanceId, Placement.AvailabilityZone]' \
--output=table

• ec2 describe-instances : EC2 인스턴스의 상세 정보를 가져오는 명령입니다.
• --region ap-northeast-2 : 명령이 실행될 리전을 지정합니다. 여기서는 서울 리전(ap-northeast-2)으로 지정되어 있습니다.
• --query 'Reservations[*].Instances[*].[join(,,Tags[?Key==Name].Value), PrivateIpAddress, State.Name, InstanceType, InstanceId, Placement.AvailabilityZone]' : --query 옵션을 사용하여 출력 형식을 지정합니다. 여기서는 'Name' 키에 해당하는 태그 값을 쉼표로 결합하여 출력하도록 지정했습니다.
• --output=table : 결과를 테이블 형식으로 출력하도록 지정합니다.

$ aws --region ap-northeast-2 ec2 describe-instances \
--query 'Reservations[*].Instances[*].[join(`,`,Tags[?Key==`Name`].Value), \
