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.
NAMES server name. By default it is set to the name of last vm from database.
KEYPAIR_NAME Name of the openstack keypair to be used to create VM. Note this is
not a path to key.
NEWNAMES New names of the VM while renaming.
OLDNAMES Old names of the VM while renaming.
Options:
--username=USERNAME the username to login into the vm. If not specified it will be guessed
from the image name and the cloud
--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 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 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 rename/ delete vms without user's confirmation
--command=COMMAND
specify the commands to be executed
Description:
commands used to boot, start or delete servers of a cloud
vm default [options...]
Displays default parameters that are set for vm boot either on the
default cloud or the specified cloud.
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 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.
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:
