C(--host) will only be used if no C(_meta) key is present. This is a performance optimization as the script would be called one additional time per host otherwise. notes: - Enabled in configuration by default. - The plugin does not cache results because external inventory scripts are responsible for their own caching. - To write your own inventory script see (R(Developing dynamic inventory,developing_inventory) from the documentation site. - To find the scripts that used to be part of the code release, go to U(https://github.com/ansible-community/contrib-scripts/). a-# fmt: code ### simple bash script #!/usr/bin/env bash if [ "$1" == "--list" ]; then cat<" exit 1 fi ### python example with ini config #!/usr/bin/env python """ # ansible_inventory.py """ import argparse import json import os.path import sys from configparser import ConfigParser from inventories.custom import MyInventoryAPI def load_config() -> ConfigParser: cp = ConfigParser() config_file = os.path.expanduser("~/.config/ansible_inventory_script.cfg") cp.read(config_file) if not cp.has_option('DEFAULT', 'namespace'): raise ValueError("Missing configuration option: DEFAULT -> namespace") return cp def get_api_data(namespace: str, pretty=False) -> str: """ :param namespace: parameter for our custom api :param pretty: Human redable JSON vs machine readable :return: JSON string """ found_data = list(MyInventoryAPI(namespace)) hostvars = {} data = { '_meta': { 'hostvars': {}},} groups = found_data['groups'].keys() for group in groups: groups[group]['hosts'] = found_data[groups].get('host_list', []) if group not in data: data[group] = {} data[group]['hosts'] = found_data[groups].get('host_list', []) data[group]['vars'] = found_data[groups].get('info', []) data[group]['children'] = found_data[group].get('subgroups', []) for host_data in found_data['hosts']: for name in host_data.items(): # turn info into vars data['_meta'][name] = found_data[name].get('info', {}) # set ansible_host if possible if 'address' in found_data[name]: data[name]['_meta']['ansible_host'] = found_data[name]['address'] data['_meta']['hostvars'] = hostvars return json.dumps(data, indent=pretty) if __name__ == '__main__': arg_parser = argparse.ArgumentParser( description=__doc__, prog=__file__) arg_parser.add_argument('--pretty', action='store_true', default=False, help="Pretty JSON") mandatory_options = arg_parser.add_mutually_exclusive_group() mandatory_options.add_argument('--list', action='store', nargs="*", help="Get inventory JSON from our API") mandatory_options.add_argument('--host', action='store', help="Get variables for specific host, not used but kept for compatibility") try: config = load_config() namespace = config.get('DEFAULT', 'namespace') args = arg_parser.parse_args() if args.host: print('{"_meta":{}}') sys.stderr.write('This script already provides _meta via --list, so this option is really ignored') elif len(args.list) >= 0: print(get_api_data(namespace, args.pretty)) else: raise ValueError("Valid options are --list or --host ") except ValueError: raise N)Mapping) AnsibleErrorAnsibleParserError)json_dict_bytes_to_unicode) to_nativeto_text)BaseInventoryPlugin)DisplaycHeZdZdZdZfdZfdZdfd ZdZdZ xZ S) InventoryModulezE Host inventory parser for ansible using external inventory scripts. scriptcHtt| t|_yN)superr __init__set_hosts)self __class__s P/home/dcms/DCMS/lib/python3.12/site-packages/ansible/plugins/inventory/script.pyrzInventoryModule.__init__s ot-/e c0tt| |}|rdd} t|d5}|j d}|j drd}dddtj|tjs|sd}|S#1swY3xYw#t $rYAwxYw)zP Verify if file is usable by this plugin, base does minimal accessibility check Frbs#!TN) rr verify_fileopenread startswith ExceptionosaccessX_OK)rpathvalidshebang_presentinv_file initial_charsrs rrzInventoryModule.verify_filesot8> #O $%/$,MM!$4M$//6*./99T277+O //  s( B %A= B =BB BBc tt| ||||j|dg} t j |tj tj }|j\}} t|}t| xsd} | r| jds| dz } |jd k7rtd |d | d t|d } |j$j'| d} | r6|j)dr%|j*j-t| t/| t0stdj#|| d} d}| j3D]'\} }| dk(r d|vs|d}|j5| |)|j6D]?}i}||j9||}n |j;|i}|j?|g|Ay#t$r/}tddj|dt|dd}~wwxYw#t $r)}tdj#|t|d}~wwxYw#t $r*}tdj#|t|| d}~wwxYw#t<$r!}td|dt||d}~wwxYw#t $r}tt|d}~wwxYw)Nz--liststdoutstderrproblem running   () rInventory script () had an execution error: strict)errorszKInventory {0} contained characters that cannot be interpreted as UTF-8: {1}T) json_onlyzEfailed to parse executable inventory script results from {0}: {1} {2}always_show_stderr)msgzYfailed to parse executable inventory script results from {0}: needs to be a json dict {1}_metahostvarsz*Improperly formatted host information for z: )orig_exc) rr parse set_options subprocessPopenPIPEOSErrorrjoinr communicateendswith returncoderr r formatloaderload get_optiondisplayerror isinstanceritems _parse_grouprget_host_variablesgetAttributeError_populate_host_vars)r inventoryrHr$cachecmdsper+r,errdata processedgroupdata_from_metagdatahostgotrs rr=zInventoryModule.parses ot*9fdC  X= 3 d%%c*//*//Z "~~/ VVT?DFLb)C3<<-t }}!"Z^`c#dee Mvh7 M KK,,TT,B $//*>?
