Configuration is read from 'cloudstack.ini'. If you need to pass the project, write a simple wrapper script, e.g. project_cloudstack.sh: #!/bin/bash cloudstack.py --project $@ When run against a specific host, this script returns the following attributes based on the data obtained from CloudStack API: "web01": { "cpu_number": 2, "nic": [ { "ip": "10.102.76.98", "mac": "02:00:50:99:00:01", "type": "Isolated", "netmask": "255.255.255.0", "gateway": "10.102.76.1" }, { "ip": "10.102.138.63", "mac": "06:b7:5a:00:14:84", "type": "Shared", "netmask": "255.255.255.0", "gateway": "10.102.138.1" } ], "default_ip": "10.102.76.98", "zone": "ZUERICH", "created": "2014-07-02T07:53:50+0200", "hypervisor": "VMware", "memory": 2048, "state": "Running", "tags": [], "cpu_speed": 1800, "affinity_group": [], "service_offering": "Small", "cpu_used": "62%" } usage: cloudstack.py [--list] [--host HOST] [--project PROJECT] """ import os import sys import argparse try: import json except: import simplejson as json try: from cs import CloudStack, CloudStackException, read_config except ImportError: print >> sys.stderr, "Error: CloudStack library must be installed: pip install cs." sys.exit(1) class CloudStackInventory(object): def __init__(self): parser = argparse.ArgumentParser() parser.add_argument('--host') parser.add_argument('--list', action='store_true') parser.add_argument('--project') options = parser.parse_args() try: self.cs = CloudStack(**read_config()) except CloudStackException as e: print >> sys.stderr, "Error: Could not connect to CloudStack API" project_id = '' if options.project: project_id = self.get_project_id(options.project) if options.host: data = self.get_host(options.host) print json.dumps(data, indent=2) elif options.list: data = self.get_list() print json.dumps(data, indent=2) else: print >> sys.stderr, "usage: --list | --host [--project ]" sys.exit(1) def get_project_id(self, project): projects = self.cs.listProjects() if projects: for p in projects['project']: if p['name'] == project or p['id'] == project: return p['id'] print >> sys.stderr, "Error: Project %s not found." % project sys.exit(1) def get_host(self, name, project_id=''): hosts = self.cs.listVirtualMachines(projectid=project_id) data = {} if not hosts: return data for host in hosts['virtualmachine']: host_name = host['displayname'] if name == host_name: data['zone'] = host['zonename'] if 'group' in host: data['group'] = host['group'] data['state'] = host['state'] data['service_offering'] = host['serviceofferingname'] data['affinity_group'] = host['affinitygroup'] data['security_group'] = host['securitygroup'] data['cpu_number'] = host['cpunumber'] data['cpu_speed'] = host['cpuspeed'] if 'cpuused' in host: data['cpu_used'] = host['cpuused'] data['memory'] = host['memory'] data['tags'] = host['tags'] data['hypervisor'] = host['hypervisor'] data['created'] = host['created'] data['nic'] = [] for nic in host['nic']: data['nic'].append({ 'ip': nic['ipaddress'], 'mac': nic['macaddress'], 'netmask': nic['netmask'], 'gateway': nic['gateway'], 'type': nic['type'], }) if nic['isdefault']: data['default_ip'] = nic['ipaddress'] break;
