If your just trying to get the syntax of the json right, there are easier
ways to test. heres the above as an inventory script.
#!/usr/bin/env python
import json
inv = {
"company": {
"hosts": [
"server",
"sensor"
]
},
"_meta": {
"hostvars": {
"server": {
"ansible_ssh_host" : "7.7.7.7",
"ansible_ssh_port" : 44
},
"sensor": {
"ansible_ssh_host" : "7.7.7.7",
"ansible_ssh_port" : "33"
}
}
}
}
print(json.dumps(inv))
heres the output of some test commands with (with ansible 2.0rc8, but it
should work the same with 1.9x)
$ ansible -i leon.py all --list-hosts
hosts (2):
server
sensor
$ ansible -i leon.py sensor -m debug -a var=vars
sensor | SUCCESS => {
"vars": {
"ansible_ssh_host": "7.7.7.7",
"ansible_ssh_port": "33",
"group_names": [
"company"
],
"inventory_hostname": "sensor",
"inventory_hostname_short": "sensor"
}
}
