Arguments:
COMMAND positional arguments, the commands you want to
execute on the server(e.g. ls -a) separated by ';',
you will get a return of executing result instead of login to
the server, note that type in -- is suggested before
you input the commands
NAME server name. By default it is set to the name of last vm from database.
NAME_OR_ID server name or ID
KEYPAIR_NAME Name of the openstack keypair to be used to create VM. Note this is not a path to key.
NEWNAME New name of the VM while renaming.
Options:
--ip=IP give the public ip of the server
--cloud=CLOUD give a cloud to work on, if not given, selected
or default cloud will be used
--count=COUNT give the number of servers to start
--detail for table print format, a brief version
is used as default, use this flag to print
detailed table
--flavor=FLAVOR_OR_ID give the name or id of the flavor
--group=GROUP give the group name of server
--secgroup=SECGROUP security group name for the server
--image=IMAGE_OR_ID give the name or id of the image
--key=KEY specify a key to use, input a string which
is the full path to the private key file
--keypair_name=KEYPAIR_NAME Name of the openstack keypair to be used to create VM.
Note this is not a path to key.
--user=USER give the user name of the server that you want
to use to login
--name=NAME give the name of the virtual machine
--force delete vms without user's confirmation
--command=COMMAND
specify the commands to be executed
--new=NEWNAME Specify the new name for a VM while renaming.
By default, this will be set to <username>-<count> format.
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']

Usage:

managing the admins test test test test
Arguments:
KEY the name of the admin
VALUE the value to set the key to
Options:
--cloud=CLOUD the name of the cloud
--format=FORMAT the output format [default: table]
Description:
Cloudmesh contains a cloudmesh.yaml file that contains
templates for multiple clouds that you may or may not have
access to. Hence it is useful to activate and deactivate clouds
you like to use in other commands.
To activate a cloud a user can simply use the activate
command followed by the name of the cloud to be
activated. To find out which clouds are available you can
use the list command that will provide you with some
basic information. As default it will print a table. Thus
the commands::
cloud activate india
cloud deactivate aws
Will result in
+----------------------+--------+-------------------+
| Cloud name | Active | Type |
+----------------------+--------+-------------------+
| india | True | Openstack |
+----------------------+--------+-------------------+
| aws | False | AWS |
+----------------------+--------+-------------------+
To get ore information about the cloud you can use the command
cloud info CLOUD
It will call internally also the command uses in register
