yle-aws-role

Tooling to help to assume AWS IAM roles.

Offers a command-line helper tool, asu, and a Ruby library. After assuming the specified role, it sets the standard environment variables and configures the Ruby SDK for the role.

Installation

The project can be installed in a shell:

gem install yle-aws-role

To use the Ruby library, add this line to your application's Gemfile:

gem 'yle-aws-role'

and then execute bundle

Usage

Usage: asu <account> [options] -- [command ...]
   or: asu --list

    account         The account ID or pattern of the role account
    command         Command to execute with the role. Defaults to launching new shell session.

    -d, --duration  Duration for the role credentials. Default: 900
    --env           Print out environment variables and exit
    -l, --list      Print out all configured account aliases
    -q, --quiet     Be quiet
    -r, --role      Name of the role

    -h, --help      Prints this help
    -v, --version   Prints the version information

Configuration

Account aliases and their IDs can be specified in a configuration file. Then you can list the known accounts with asu --list, and use aliases (even with partial matching) when specifying the account for asu. Also the default role can be set.

The configuration file location defaults to $HOME/.aws/asu.yaml, but can be specified with the ASU_CONFIG environment variable.

Example configuration:

defaults:
  role: "dev"

accounts:
  foo-bar: "123456789012"
  baz:     "987654321098"

With this you can just call for example

asu foo -- aws s3 ls s3://mybucket/
