AWS CLI

• AWS CLI is a command line interface to interact with AWS
• AWS CLI can be installed on Windows, Linux or mac
• To authenticate AWS CLI we need IAM user.
• Lets generate IAM Credentials (Secret Access Key Id, Secret Access Key)
• Navigate to IAM in services from console
  
  
  
  
  
  
  
• Now execute aws configure
  

How to work on CLI

• AWS CLI will have following format

aws <service> <command/action> [--arg1 value1] .. [--argn valuen]

• Refer Here for aws ec2 commands.
• Generally commands will have following prefixes
  • to view describe* list*
  • to create create* run*
  • to delete delete* terminate*
  • to modify modify* update*
• AWS CLI relies on ID’s rather than names in many cases
• for all the commands --region and --query are supported

Exercise

• Get all the vpcs from aws cli for a particular region aws ec2 describe-vpcs --region us-west-2
• Get all the security groups aws ec2 describe-security-groups
• Get the AMI id of the ubuntu 22.04
