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 ssh [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. vm refresh [--cloud=CLOUDS] this command refreshes the data for virtual machines, images and flavors for the specified clouds. vm ping [NAMES] [--cloud=CLOUDS] [--count=N] [--processors=PROCESSORS] pings the specified virtual machines, while using at most N pings. The ping is executed in parallel. If names are specifies the ping is restricted to the given names in parameter format. If clouds are specified, names that are not in these clouds are ignored.

With SHELL you can set the shell for executing the command, this coudl even be a python interpreter. Examples for SHELL are /bin/sh, /usr/bin/env python vm put SOURCE DESTINATION [NAMES] puts the file defined by SOURCE into the DESINATION folder on the specified machines. If the file exists it is overwritten, so be careful. vm get SOURCE DESTINATION [NAMES] gets the file defined by SOURCE into the DESINATION folder on the specified machines. The SOURCE is on the remote machine. If one machine is specified, the SOURCE is the same name as on the remote machine. If multiple machines are specified, the name of the machine will be a prefix to the filename. If the filenames exists, they will be overwritten, so be careful. 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'] Quoting commands: cm vm login gregor-004 --command=\"uname -a\" Limitations: Azure: rename is not supported """ map_parameters(arguments, 'active', 'cloud', 'command', 'dryrun', 'flavor', 'force', 'group' 'output', 'group', 'image', 'interval', 'timeout', 'ip', 'key', 'modify-knownhosts', 'n', 'name', 'public', 'quiet', 'secgroup', 'size', 'username', 'output', 'count', 'network', 'refresh') variables = Variables() database = CmDatabase() arguments.output = Parameter.find("output", arguments, variables, "table") arguments.refresh = Parameter.find_bool("refresh", arguments, variables) if (arguments.meta and arguments.list): name = arguments.NAME if arguments.NAME is None: name = variables['vm'] if name is None: Console.error("No vm specified") cloud = "chameleon" # cloud = Parameter.find(arguments, variables) print(f"vm metadata for {name} on {cloud}") provider = Provider(name=cloud) r = provider.get_server_metadata(name) print(r) elif arguments.meta and arguments.set: metadata = {} pairs = arguments['KEY=VALUE'] for pair in pairs: key, value = pair.split("=", 1) metadata[key] = value name = arguments.NAME if arguments.NAME is None: name = variables['vm'] if name is None: Console.error("No vm specified") cloud = "chameleon" # cloud = Parameter.find(arguments, variables) print(f"cloud {cloud} {name}") provider = Provider(name=cloud) provider.set_server_metadata(name, **metadata) r = provider.get_server_metadata(name) pprint(r) elif arguments.meta and arguments.delete: metadata = {} keys = arguments['KEY'] name = arguments.NAME if arguments.NAME is None: name = variables['vm'] if name is None: Console.error("No vm specified") cloud = "chameleon" # cloud = Parameter.find(arguments, variables) print(f"cloud {cloud} {name}") provider = Provider(name=cloud) for key in keys: provider.delete_server_metadata(name, key) r = provider.get_server_metadata(name) pprint(r) elif arguments.list and arguments.refresh: names = [] clouds, names = Arguments.get_cloud_and_names( "list", arguments, variables) for cloud in clouds: print(f"cloud {cloud}") provider = Provider(name=cloud) vms = provider.list() provider.Print(vms, output=arguments.output, kind="vm") return "" elif arguments.list: names = [] clouds, names = Arguments.get_cloud_and_names( "list", arguments, variables) try: for cloud in clouds: print(f"List {cloud}") p = Provider(cloud) kind = p.kind collection = "{cloud}-vm".format(cloud=cloud, kind=p.kind) db = CmDatabase() vms = db.find(collection=collection) p.Print(vms, output=arguments.output, kind="vm") except Exception as e: Console.error("Error in listing ", traceflag=True) VERBOSE(e) return "" elif arguments.ping: """ vm ping [NAMES] [--cloud=CLOUDS] [--count=N] """ if arguments.NAMES: variables['vm'] = arguments.NAMES if arguments['--cloud']: variables['cloud'] = arguments['--cloud'] clouds, names = Arguments.get_cloud_and_names( "status", arguments, variables) count = arguments.count if arguments.count: count = int(count) else: count = 1 def get_ips(): ips = [] for cloud in clouds: params = {} # gets public ips from database cursor = database.db[f'{cloud}-vm'] for name in names: for node in cursor.find({'name': name}): ips.append(node['ip_public']) ips = list(set(ips)) pprint(ips) return ips ips = get_ips() if len(ips) == 0: Console.warning("no public ip found.") for cloud in clouds: print(f"refresh for cloud {cloud}") provider = Provider(name=cloud) vms = provider.list() ips = get_ips() if len(ips) == 0: Console.error("No vms with public IPS found.")
