AWS command line interface is a tool to manage aws services through command line.
https://aws.amazon.com/cli/ : aws cli download
We commonly use aws using IAM user. After creating IAM user download credentials which are downloaded in .csv format.
After downloading aws cli and installing it open command prompt in windows or shell in linux.
To check whether aws cli installed or not run:
aws --version
To configure user in aws cli run :
aws configure
Put your downloaded credentials of user in output of above command to set that user in aws cli to manage services.
To check all metadata of ec2 instances we have:
aws ec2 describe-instances
To see volumes info for ec2 instances we have:
aws ec2 describe-volumes
For key related operations we have :
aws ec2 describe-key-pairs aws ec2 describe-key-pairs --query KeyPairs aws ec2 describe-key-pairs --query KeyPairs[0] #for 1st key pair aws ec2 describe-key-pairs --query KeyPairs[0]."KeyName" #to extract key name aws ec2 create-key-pair --help
Instance Related Queries to pull out some specific info :
aws ec2 describe-instances aws ec2 describe-instances --query Reservations[0].Instances[0]."PublicIpAddress" aws ec2 describe-instances --query Reservations[0].Instances[1].["PublicIpAddress","KeyName"] aws ec2 describe-instances --query Reservations[1].Instances[0].["PublicIpAddress","KeyName"] aws ec2 describe-instances --query Reservations[*].Instances[0].["PublicIpAddress","KeyName","InstanceId","Tags"] aws ec2 describe-instances --query Reservations[*].Instances[0].["PublicIpAddress","KeyName","InstanceId",Tags[*].Values]
