Fixes #23095 Fixed issue preventing a caller from setting a docker configuration file (e.g. docker.yml) by specifing the config file path in the `DOCKER_CONFIG_FILE` environment variable. Previously, the cli argument parser set a default value for the `--config-file` argument which would prevent ever checking the environment variable, regardless of whether or not the `--config-file` argument even specified a valid file. This commit adds a global `DEFAULT_DOCKER_CONFIG_FILE` variable, which points to the current default `docker.yml` config in the contrib/inventory directory. Now, when this script is called from the command line, the config file passed with the cli `--config-file` arg will be given the highest precedence; if it is absent, this script will then check if the `DOCKER_CONFIG_FILE` env var is set, and load the config file specified if possible. If neither the environment variable or cli argument are specified, then the script will attempt to parse the config file `docker.yml` in this script's directory (if present). If either the `DOCKER_CONFIG_FILE` environment variable or the `--config-file` argument are given but point to a nonexistant file, then the script will print an error message and exit with an error code. It is *not* an error condition if the fallback `docker.yml` does not exist. |

contrib
Files here provide an extension mechanism for Ansible similar to plugins. They are not maintained by the Ansible core team or installed with Ansible.
inventory
Before 2.4 introduced inventory plugins, inventory scripts were the only way to provide sources that were not built into Ansible. Inventory scripts allow you to store your hosts, groups, and variables in any way you like.
Starting with Ansible version 2.4, they are enabled via the 'script' inventory plugin. Examples of use include discovering inventory from EC2 or pulling it from Cobbler. These could also be used to interface with LDAP or the database.
chmod +x an inventory plugin and either name it /etc/ansible/hosts or use ansible -i /path/to/inventory/script. You might also need to copy a configuration file with the same name and/or set environment variables. The scripts or configuration files can provide more details.
vault
If the file passed to --vault-password-file has the executable bit set, Ansible will execute it and use the stdout of that execution as 'the secret'.
Vault scripts provided here use this facility to retrieve the vault secret from a number of sources.
