inventory.py 要有可执行位:
#!/usr/bin/env python3
#coding = utf8
import json
import sys
def group():
hosts = ['serverb','serverc','serverd']
group = 'srvgroup'
vars = {'ansible_ssh_port': 22, 'ansible_connection': 'ssh'}
hostdata = {group:{"hosts": hosts, "vars": vars}}
print(json.dumps(hostdata, indent=4))
if len(sys.argv) == 2 and (sys.argv == '--list'):
group()
else:
print("Usage: %s --list or --host <hostname>" % sys.argv)
sys.exit(1)

$ ./inventory.py--list
