wrote a dynamic inventory for ansible, which seems to run fine on its own,
but when run in ansible, it complains that it cant import yaml.
a script that just cats out the output (cut and paste) of the first script
works just fine. the parts that actually make and configure the virtual
machines and networks works fine, so thats stripped out.
im on os x 10.10.4, running ansible 1.9.2 from homebrew
pixel$ ./pransible-stripped.py --list
{
"fileserver": {
...
pixel$ ansible -i ./pransible-stripped.py all --list-hosts

heres the script,
============
#!/usr/bin/env python3
import json
import yaml
class ProxSession:
"""Connection to a proxmox host or cluster for setting or getting kvm
instances"""
def __init__(self,config_file):
with open(config_file) as fp:
self.siteconfig = yaml.load(fp.read())
def inventory(self):
i = {'_meta':{'hostvars':{}}}
for template,clones in self.siteconfig['clones'].items():
for clone,v in clones.items():
if 'groups' in v:
for group in v['groups']:
if group not in i:
i[group] = {'hosts':[clone]}
else:
i[group]['hosts'].append(clone)
if 'vars' in v:
i['_meta']['hostvars'][clone] = v['vars']
if 'group_vars' in self.siteconfig:
for k,v in self.siteconfig['group_vars'].items():
i[k]['vars'] = v
return json.dumps(i,indent=2)
if __name__ == '__main__':
p = ProxSession('test.yaml')
print (p.inventory())
exit
and the input, (those networks only exist in the test environment)
