cluster delete NAME
cluster setup NAME [--username]
cluster inventory NAME
Description:
with the help of the cluster command you can create a number
of virtual machines that are integrated in a named virtual cluster.
You will be able to login between the nodes of the virtual cluster
while using public keys.
cluster setup NAME
sets up the keys between the cluster node as well as the machine that
executes the cm command
cluster inventory NAME
creates an inventory.txt file to be used by ansible in the current directory
cluster create NAME
creates the virtual machines used for the cluster
cluster list NAME
lists selected details of the vms for the cluster
cluster delete NAME
remove the cluster and its VMs
Examples:
cluster list
list the clusters
cluster create NAME --count=COUNT --login=USERNAME [options...]
Start a cluster of VMs, and each of them can log into each other.
CAUTION: you should specify defaults before using this command:
1. select cloud to work on, e.g. cloud select kilo
default cloud=kilo
2. test if you can create a single VM on the cloud to see if
everything is set up
3. set the default key to start VMs, e.g. key default [USERNAME-key]
5. set image of VMs, e.g. default image
6. set flavor of VMs, e.g. default flavor
7. Make sure to use a new unused group name
Arguments:
NAME cluster name or group name
Options:
--count=COUNT give the number of VMs to add into the cluster
--login=USERNAME give a login name for the VMs, e.g. ubuntu
--cloud=CLOUD give a cloud to work on
--flavor=FLAVOR give the name of the flavor or flavor id
--image=IMAGE give the name of the image or image id
--add if a group exists and there are VMs in it
additional vms will be added to this cluster and the
keys will be added to each other so one can login between
them
FORMAT output format: table, json, csv
COLUMN customize what information to display, for example:
--column=status,addresses prints the columns status
and addresses
--detail for table print format, a brief version
is used as default, use this flag to print
detailed table

--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.
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']

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.
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:
cm vm login gvonlasz-004 --command=\"uname -a\"

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']

[--login=USERNAME]
[--cloud=CLOUD]
[--image=IMAGE]
[--flavor=FLAVOR]
[--add]
cluster delete NAME
cluster setup NAME [--username]
cluster inventory NAME
Description:
with the help of the cluster command you can create a number
of virtual machines that are integrated in a named virtual cluster.
You will be able to login between the nodes of the virtual cluster
while using public keys.
cluster setup NAME
sets up the keys between the cluster node as well as the machine that
executes the cm command
cluster inventory NAME
creates an inventory.txt file to be used by ansible in the current directory
cluster create NAME
creates the virtual machines used for the cluster
cluster list NAME
lists selected details of the vms for the cluster
cluster delete NAME
remove the cluster and its VMs
Examples:
cluster list
list the clusters
cluster create NAME --count=COUNT --login=USERNAME [options...]
Start a cluster of VMs, and each of them can log into each other.
CAUTION: you should specify defaults before using this command:
1. select cloud to work on, e.g. cloud select kilo
default cloud=kilo
2. test if you can create a single VM on the cloud to see if
everything is set up
3. set the default key to start VMs, e.g. key default [USERNAME-key]
5. set image of VMs, e.g. default image
6. set flavor of VMs, e.g. default flavor
7. Make sure to use a new unused group name
Arguments:
NAME cluster name or group name
Options:
--count=COUNT give the number of VMs to add into the cluster
--login=USERNAME give a login name for the VMs, e.g. ubuntu
--cloud=CLOUD give a cloud to work on
--flavor=FLAVOR give the name of the flavor or flavor id
--image=IMAGE give the name of the image or image id
--add if a group exists and there are VMs in it
additional vms will be added to this cluster and the
keys will be added to each other so one can login between
them
FORMAT output format: table, json, csv
COLUMN customize what information to display, for example:
--column=status,addresses prints the columns status
and addresses
--detail for table print format, a brief version
is used as default, use this flag to print
detailed table

--tenant=TENANT Name of the tenant, e.g. fg82.
Description:
List command prints the values stored in the database
for [default/vm/flavor/image].
Result can be filtered based on the cloud, user & tenant arguments.
If these arguments are not specified, it reads the default
Examples:
$ list --cloud india default
$ list --cloud india --format table flavor
$ list --cloud india --user albert --tenant fg82 flavor
