# =============================================================================
#
# This script is to be used with ansible-vault's --vault-id arg
# 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.org/project/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'
#
# In useage like:
#
# ansible-vault --vault-id keyring_id@contrib/vault/vault-keyring-client.py view some_encrypted_file
#
# --vault-id will call this script like:
#
# contrib/vault/vault-keyring-client.py --vault-id keyring_id
#
# That will retrieve the password from users keyring for the
# keyring service 'keyring_id'. The equivalent of:
#
# keyring get keyring_id $USER
#
# If no vault-id name is specified to ansible command line, the vault-keyring-client.py
# script will be called without a '--vault-id' and will default to the keyring service 'ansible'
# This is equivalent to:
#
# keyring get ansible $USER
#
# You can configure the `vault_password_file` option in ansible.cfg:
#
# [defaults]
# ...
# vault_password_file = /path/to/vault-keyring-client.py
# ...
#
# To set your password, `cd` to your project directory and run:
#
# # will use default keyring service / vault-id of 'ansible'
# /path/to/vault-keyring-client.py --set
#
# or to specify the keyring service / vault-id of 'my_ansible_secret':
#
# /path/to/vault-keyring-client.py --vault-id my_ansible_secret --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-id=keyring_id@/path/to/vault-keyring-client.py site.yml
