# =============================================================================
#
# This script is to be used with vault_password_file or --vault-password-file
# to retrieve the vault password via your OS's native keyring application.
#
# This file *MUST* be saved with executable permissions. Otherwise, Ansible
# will try to parse as a password file and display: "ERROR! Decryption failed"
#
# The `keyring` Python module is required: https://pypi.python.org/pypi/keyring
#
# By default, this script will store the specified password in the keyring of
# the user that invokes the script. To specify a user keyring, add a [vault]
# section to your ansible.cfg file with a 'username' option. Example:
#
# [vault]
# username = 'ansible-vault'
#
# Another optional setting is for the key name, which allows you to use this
# script to handle multiple project vaults with different passwords:
#
# [vault]
# keyname = 'ansible-vault-yourproject'
#
# You can configure the `vault_password_file` option in ansible.cfg:
#
# [defaults]
# ...
# vault_password_file = /path/to/vault-keyring.py
# ...
#
# To set your password, `cd` to your project directory and run:
#
# python /path/to/vault-keyring.py set
#
# If you choose not to configure the path to `vault_password_file` in
# ansible.cfg, your `ansible-playbook` command might look like:
#
# ansible-playbook --vault-password-file=/path/to/vault-keyring.py site.yml
