AWS : CLI

AWS CLI

Amazon Virtual Private Cloud (Amazon VPC) enables you to launch AWS resources into a virtual network that you’ve defined. This virtual network closely resembles a traditional network that you’d operate in your own data center, with the benefits of using the scalable infrastructure of AWS.

Profile Setup

A named profile is a collection of settings and credentials that you can apply to a AWS CLI command. When you specify a profile to run a command, the settings and credentials are used to run that command.

• ~/.aws/credentials

  [default]
  aws_access_key_id=your_aws_access_key_id
  aws_secret_access_key=your_aws_secret_access_key
  

• ~/.aws/config

  [default]
  region=us-west-2
  output=json
  

• The AWS CLI supports using any of multiple named profiles that are stored in the config and credentials files.

• ~/.aws/credentials (Linux / Mac)

  [default]
  aws_access_key_id=your_aws_access_key_id
  aws_secret_access_key=your_aws_secret_access_key
  
  [user1]
  aws_access_key_id=your_aws_access_key_id
  aws_secret_access_key=your_aws_secret_access_key
  

• ~/.aws/config (Linux & Mac)

  [default]
  region=us-west-2
  output=json
  
  [profile user1]
  region=us-east-1
  output=text
