AWS CLI

CLI Configuration

Quick configuration

$ 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

To update any of your settings, simply run aws configure
again and enter new values as appropriate.

# can specify a particular profile name:
$ aws configure --profile profilename

The AWS CLI looks for credentials and configuration settings in the following order:

• Command Line Options – region, output format and profile can be specified as command options to override default settings.
• Environment Variables – AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, etc.
• The AWS credentials file – located at ~/.aws/credentials. This file can contain multiple named profiles in addition to a default profile.
• The CLI configuration file – typically located at ~/.aws/config. This file can contain a default profile, named profiles, and CLI specific configuration parameters for each.
• Instance profile credentials – these credentials can be used on EC2 instances with an assigned instance role, and are delivered through the Amazon EC2 metadata service.

Configure by using credential and config files

#~/.aws/credentials
[default]
aws_access_key_id=AKIAIOSFODNN7EXAMPLE
aws_secret_access_key=wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY

[user2]
aws_access_key_id=AKIAI44QH8DHBEXAMPLE
aws_secret_access_key=je7MtGbClwBF/2Zp9Utk/h3yCo8nvbEXAMPLEKEY

#~/.aws/config
[default]
region=us-west-2
output=json

[profile user2]
region=us-east-1
output=text

• Used named profile with CLI:

$ aws ec2 describe-instances --profile user2

• you can avoid specifying the profile in every command by setting the AWS_DEFAULT_PROFILE environment variable at the command line:

$ export AWS_DEFAULT_PROFILE=user2

• Command line option
  The following settings can be specified at the command line.
  --profile – name of a profile to use, or "default" to use the default profile.
  --region – AWS region to call.
  --output – output format.
  --endpoint-url

• test CLI configuration with list EC2 instance:

aws ec2 describe-instances --profile jinchao-full-access --output table --region us-west-2
