awsudo + aws-agent

Overview

awsudo enables users to execute commands that make API calls to AWS under the security context of an IAM role. The IAM role is assumed only upon successful authentication against a SAML compliant federation service.

aws-agent enables users to authenticate against a SAML compliant federation service once, after which aws-agent provides temporary credentials to awsudo to use.

Synopsis

  awsudo {role-name | role-arn} command
 
  aws-agent

Requirements

  • UNIX, UNIX-like or GNU/Linux operating system
  • SAML compliant federation service
  • ruby 1.9 or above
  • ruby gems: aws-sdk

Install

  git clone https://github.com/electronicarts/awsudo.git
  cd awsudo
  gem build awsudo.gemspec
  sudo gem install awsudo-<version>.gem

Configuration

awsudo and aws-agent expect a configuration file named .awsudo in your home directory containing the values for your identity provider login url and the SAML provider name configured in AWS. This is an example, your setup may vary:

  IDP_LOGIN_URL = https://sts.example.com/adfs/ls/IdpInitiatedSignOn.aspx?loginToRp=urn:amazon:webservices
  SAML_PROVIDER_NAME = ADFS

In addition to .awsudo, you can create .aws-roles in your home directory to map IAM roles ARNs to more easy to remember alias names, one per line, separated by spaces. Example:

  myaccount-admin  arn:aws:iam::123456789012:role/myaccount-admin

Examples

awsudo

  $ awsudo arn:aws:iam::123456789012:role/myaccount-admin aws ec2 describe-tags --region us-west-2

  $ awsudo myaccount-admin aws ec2 describe-instances --region us-east-1

awsudo will ask your federated credentials every time. To avoid this use aws-agent as follows:

aws-agent

  $ aws-agent
  Login: username
  Password:
  AWS_AUTH_SOCK=/var/folders/xz/lx178g0d0rb36x95446zwgd80000gp/T/aws-20150623-20990-58v1c4/agent; export AWS_AUTH_SOCK;

then execute the commands printed by aws-agent. awsudo will now ask for temporary credentials to aws-agent.
