Description: commands used to boot, start or delete servers of a cloud vm default [options...] Displays default parameters that are set for VM boot. vm boot [options...] Boots servers on a cloud, user may specify flavor, image .etc, otherwise default values will be used, see how to set default values of a cloud: cloud help vm start [options...] Starts a suspended or stopped vm instance. vm stop [options...] Stops a vm instance . vm delete [options...] delete servers of a cloud, user may delete a server by its name or id, delete servers of a group or servers of a cloud, give prefix and/or range to find servers by their names. Or user may specify more options to narrow the search vm floating_ip_assign [options...] assign a public ip to a VM of a cloud vm ip show [options...] show the ips of VMs vm login [options...] login to a server or execute commands on it vm list [options...] same as command "list vm", please refer to it vm status [options...] Retrieves status of last VM booted on cloud and displays it. Tip: give the VM name, but in a hostlist style, which is very convenient when you need a range of VMs e.g. sample[1-3] => ['sample1', 'sample2', 'sample3'] sample[1-3,18] => ['sample1', 'sample2', 'sample3', 'sample18'] """ def _print_dict(d, header=None, format='table'): if format == "json": return json.dumps(d, indent=4) elif format == "yaml": return pyaml.dump(d) elif format == "table": return dict_printer(d, order=["id", "name", "status"], output="table", sort_keys=True) else: return d def _print_dict_ip(d, header=None, format='table'): if format == "json": return json.dumps(d, indent=4) elif format == "yaml": return pyaml.dump(d) elif format == "table": return dict_printer(d, order=["network", "version", "addr"], output="table", sort_keys=True) else: return d """ def list_vms_on_cloud(cloud="kilo", group=None, format="table"): Utility reusable function to list vms on the cloud. :param cloud: :param group: :param format: :return: _cloud = cloud _group = group _format = format cloud_provider = CloudProvider(_cloud).provider servers = cloud_provider.list_vm(_cloud) server_list = {} index = 0 # TODO: Improve the implementation to display more fields if required. for server in servers: server_list[index] = {} server_list[index]["name"] = server.name server_list[index]["id"] = server.id server_list[index]["status"] = server.status index += 1 # TODO: Get this printed in a table print("Print table") dict_printer(servers, output=_format) """ # pprint(arguments) def _refresh(): try: msg = "Refresh VMs for cloud {:}.".format(cloud) if Vm.refresh(cloud=cloud): Console.ok("{:} OK.".format(msg)) else: Console.error("{:} failed".format(msg)) except Exception as e: Error.traceback(e) Console.error("Problem running VM refresh") cloud = arguments["--cloud"] or Default.get_cloud() if arguments["boot"]: name = None try: name = arguments["--name"] is_name_provided = True if name is None: is_name_provided = False count = Counter.get() prefix = Username() if prefix is None or count is None: Console.error( "Prefix and Count could not be retrieved correctly." ) return # BUG THE Z FILL SHOULD BE detected from yaml file name = prefix + "-" + str(count).zfill(3) # if default cloud not set, return error if not cloud: Console.error("Default cloud not set.") return "" image = arguments["--image"] or Default.get("image", category=cloud) # if default image not set, return error if not image: Console.error("Default image not set.") return "" flavor = arguments["--flavor"] or Default.get("flavor", category=cloud) # if default flavor not set, return error if not flavor: Console.error("Default flavor not set.") return "" group = arguments["--group"] or Default.get_group() # if default group not set, return error if not group: group = "default" Default.set_group(group) secgroup = arguments["--secgroup"] or Default.get( "secgroup", category=cloud) # print("SecurityGrp : {:}".format(secgroup)) secgroup_list = ["default"] if secgroup is not None: secgroup_list.append(secgroup) key_name = arguments["--key"] or Default.get_key() # if default keypair not set, return error if not key_name: Console.error("Default key not set.") return "" if arguments["--dryrun"]: data = { "cloud": cloud, "name": name, "image": image, "flavor": flavor, "key_name": key_name, "secgroup_list": secgroup_list, "group": group } print(attribute_printer(data, output="table")) msg = "dryrun info.
