How to configure the AWS CLI ?

aws configure
AWS Access Key ID [None]: AKIAIOSFODNN7EXAMPLE
AWS Secret Access Key [None]: wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY
Default region name [None]: us-west-2
Default output format [None]: json

Multiple profiles can be added to the awscli

Now we need to check if we have configured the credentials perfectly or not

aws ec2 describe-regions --output table

List the aws configured file and secure keys

ls ~/.aws

aws ec2 describe-instances --profile user2

export AWS_PROFILE=user2

The following example shows how you would configure environment variables for the default user from earlier in this guide.

Linux, macOS, or Unix

$ export AWS_ACCESS_KEY_ID=AKIAIOSFODNN7EXAMPLE
$ export AWS_SECRET_ACCESS_KEY=wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY
$ export AWS_DEFAULT_REGION=us-west-2

How to reconfigure the AWS CLI

aws configure --profile profilename

aws ec2 describe-instances --output table --region us-east-1

aws ec2 describe-instances --output table --region us-west-1
