# shows how to use the Ruby AWS SDK to list EC2 instance IDs
# when your API credentials have been placed under MFA requirements

# Prerequisites:
# you are running on a host that already has the AWS CLI set up with an IAM key pair
# that can describe EC2 instances (OTHERWISE, just pass a
# secret_access_id / secret_access_key pair to the STS client initializer)

# You have installed the Ruby AWS SDK Gem
# http://aws.amazon.com/sdk-for-ruby/

Ansible vault example

New in Ansible 1.5, “Vault” is a feature of ansible that allows keeping sensitive data such as passwords or keys in encrypted files, rather than as plaintext in your playbooks or roles. These vault files can then be distributed or placed in source control. To enable this feature, a command line tool, ansible-vault is used to edit files, and a command line flag –ask-vault-pass or –vault-password-file is used. Alternately, you may specify the location of a password file or command Ansible to always prompt for the password in your ansible.cfg file. These options require no command line flag usage.

Requirements

• ansible > 1.5
• openssl
• inventory file
• host_vars or group_vars
• ansible directory best practices structure
