DESCRIPTION
|
|
This command generates an ansible configuration file to use with this repository; it is tailored for the user calling ansible commands,
|
|
not to be used as a boilerplate for Molecule and \`ansible-test\` environments.
|
|
|
|
USAGE
|
|
\$> ./$(basename "$0") [option [option...]] [file_path]
|
|
|
|
ARGUMENTS
|
|
file_path file path where the file will be saved; defaults to '\$HOME/.ansible.cfg';
|
|
if neither this argument nor the environment variable \$ANSIBLE_CFG_PATH is provided, the
|
|
content will be printed on stdout.
|
|
|
|
OPTIONS
|
|
-h, --help show this output
|
|
-o, --overwrite allow overwriting of a pre-existing file
|
|
|
|
ENVIRONMENT
|
|
The following environment variables are supported for overrides:
|
|
ANSIBLE_CFG_PATH: path where the ansible config file should be stored (current: "${ANSIBLE_CFG_PATH:-stdout}" or argument)
|
|
TMPL_PROJECT_ROOT: path where this project is located; defaults to where '../' leads (current: "$TMPL_PROJECT_ROOT")
|
|
TMPL_INVENTORY_FILE: path where the main inventory file is located (current: "$TMPL_INVENTORY_FILE")
|
|
TMPL_CONNECTION_TIMEOUT: default connection timeout when connecting to hosts (current: $TMPL_CONNECTION_TIMEOUT)
|
|
TMPL_PLAYBOOK_DIR: path where the playbooks are located (current: "$TMPL_PLAYBOOK_DIR")
