AWS CLI configuration

First you will need to configure your AWS CLI access: aws configure or aws configure --profile your-new-profile-name. You will be prompted to enter a username and password. Configuration will be saved in directory $HOME/.aws/ in files credentials and config.

Execute aws configure list to view your actual configuration. If you execute for the first time will be something like:

 aws configure list
     Name                    Value             Type    Location
     ----                    -----             ----    --------
  profile                <not set>             None    None
  access_key             <not set>             None    None
  secret_key             <not set>             None    None
  region                 <not set>             None    None

If you have multiple profiles defined you can list them:

• aws configure list-profiles

Configuration files

• ~/.aws/config
• ~/.aws/credentials
• ~/.aws/cli/alias

Basic AWS EC2 commands

Before starting to use AWS CLI you will need to configure IAM policies for your user.

• Get a list of EC2 instances:

aws ec2 describe-instances

• Get a list of EC2 instances and filter Name, Id and Status:

aws ec2 describe-instances | egrep 'InstanceId|"Name":|"Value":|PublicIp'

• Create or run an instance

aws ec2 run-instances

• Start an EC2 instance:

aws ec2 start-instances --instance-ids i-08cf893bbcfd7dc46 (Use your own instance-id)

• Stop an EC2 instance:

aws ec2 stop-instances --instance-ids i-08cf893bbcfd7dc46 (Use your own instance-id)

• Show Relational Database Service (RDS) instances:

aws rds describe-db-instances

• Query and display EC2 metadata: ec2metadata (Distributed in cloud-guest-utils package at least in Debian)

Basic AWS S3 commands

• List your buckets: aws s3api list-buckets

• List your buckets in all regions:

for region_name in ap-south-1 eu-west-3 eu-west-2 eu-west-1 ap-northeast-2 ap-northeast-1 sa-east-1 ca-central-1 ap-southeast-1 ap-southeast-2 eu-central-1 us-east-1 us-east-2 us-west-1 us-west-2; do 
   aws s3api list-buckets --region $region_name
done

• aws s3 ls

If you do not have permisssions you will get the following error:

An error occurred (AccessDenied) when calling the ListBuckets operation: Access Denied

• aws s3 ls your_bucket_name
• aws --profile your_profile_name s3 ls your_bucket_name (You can also use a profile to define your credentials)
• aws s3 cp
• Size of a Bucket: aws s3 ls --summarize --human-readable --recursive s3://bucket-name/

Basic AWS IAM commands

• aws iam list-users

If you do not have permisssions you will get the following error:

An error occurred (AccessDenied) when calling the ListUsers operation: User: arn:aws:iam::146910341356:user/MY_USERNAME is not authorized to perform: iam:ListUsers on resource: arn:aws:iam::146910241356:user/

• aws iam list-user-policies --user-name USERNAME

Basic AWS Security commands

• Authorizing Inbond Traffic from anywhere to TCO port 80

aws ec2 describe-instance-attribute --instance-id YOUR_INSTANCE_ID --attribute groupSet

aws ec2 authorize-security-group-ingress --group-id YOUR_GROUP_ID --protocol tcp --port 80 --cidr 0.0.0.0/0

Basic AWS ECS commands

• aws ecs list-clusters

Basic AWS Config service commands

• aws configservice get-status

• aws ssm-incidents
