Arguments:
OUTPUT the output format
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 vm 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:
-v verbose, prints the dict at the end
--output=OUTPUT the output format
-H --modify-knownhosts Do not modify ~/.ssh/known_hosts file
when ssh'ing into a machine
--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, 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 vm 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.
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. If the name is set in the variables
this name is used.
cms vm ssh --command=\"uname -a\"
executes the uname command on the last booted vm
vm script [--name=NAMES]
[--username=USERNAME]
[--key=KEY]
[--dryrun]
[--dir=DESTINATION]
[--shell=SHELL]
SCRIPT
The script command copies a shell script to the specified vms
into the DESTINATION directory and than execute it. 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

Description:
Please note that some values are read from the cloudmesh.yaml
file. One such value is cloudmesh.profile.user
Manages public keys is an essential component of accessing
virtual machine sin the cloud. There are a number of sources
where you can find public keys. This includes teh ~/.ssh
directory and for example github.
Keys will be uploaded into cloudmesh database with the add
command under the given NAME. If the name is not specified the name
cloudmesh.profile.user is assumed.
key add NAME --source=ssh
adds the default key in ~/.ssh/id_rsa.pub
key add NAME --source=FILENAME
adds the key specified by the filename with the given name
key add NAME --git --username=username
adds a named github key from a user with the given github
username.
Once the keys are uploaded to github, they can be listed
To list these keys the following list functions are provided.
key list --source=git [--username=USERNAME]
lists all keys in git for the specified user. If the
name is not specified it is read from cloudmesh.yaml
key list --source=ssh [--dir=DIR] [--output=OUTPUT]
lists all keys in the directory. If the directory is not
specified the default will be ~/.ssh
key list NAMES
lists all keys in the named virtual machines.
List command can use the [--output=OUTPUT] option
list the keys loaded to cloudmesh in the given format:
json, yaml, table. table is default. The NAME can be
specified and if omitted the name cloudmesh.profile.user
is assumed.
To get keys from the cloudmesh database the following commands
are available:
key delete NAMES
deletes the Named keys. This may also have an impact on groups
key rename NAME NEW
renames the key from NAME to NEW in the cloudmesh database.
Group management of keys is an important concept in cloudmesh,
allowing multiple users to be added to virtual machines while
managing the keys associated with them. The keys must be uploaded
to cloudmesh database with a name so they can be used in a
group. The --dryrun option executes the command without
uploading the information to the clouds. If no group name is
specified the group name default is assumed. If no cloudnamesh
are specified, all active clouds are assumed. active clouds
can be set in the cloudmesh.yaml file.
key group delete [GROUPNAMES] [NAMES] [--dryrun]
deletes the named keys from the named groups.
key group list [GROUPNAMES] [--output=OUTPUT]
list the key names and details in the group.
key group upload [GROUPNAMES] [CLOUDS] [--dryrun]
uploads the named groups to the specified clouds.
In some cases you may want to store the public keys in files. For
this reason we support the following commands.
key group add --group=GROUPNAME --file=FILENAME
the command adds the keys to the given group. The keys are
written in the files in yaml format.
key group export --group=GROUNAMES --filename=FILENAME
the command exports the keys to the given group. The keys are
written in the files in yaml format.
The yaml format is as follows:
cloudmesh:
keys:
NAMEOFKEY:
name: NAMEOFKEY
key: ssh-rsa AAAA..... comment
group:
- GROUPNAME
...
If a key is included in multiple groups they will be added
to the grouplist of the key

Description:
Please note that some values are read from the cloudmesh.yaml
file. One such value is cloudmesh.profile.user
Management of public keys is an essential component of accessing
virtual machines in the cloud. There are a number of sources
where you can find public keys. This includes the ~/.ssh
directory and for example github. If you do not already have a
public-private key pair they can be generated using cloudmesh
key gen ssh
This will create the public-private keypair of ~/.ssh/id_rsa
and ~/.ssh/id_rsa.pub in OpenSSH format
key gen pem
This will create the public-private keypair of ~/.ssh/id_rsa
and ~/.ssh/id_rsa.pub in PEM format
key gen (ssh | pem) --filename=~/.cloudmesh/foobar
This will generate the public-private key pair of
~/.cloudmesh/foobar and ~/.cloudmesh/foobar.pub
key gen (ssh | pem) --filename=~/.cloudmesh/foobar --set_path
This will generate the keys as stated above, but it will
also set cloudmesh to use these keys for encryption.
Keys can also be verified for their formatting and passwords.
By default cloudmesh checks ~/.ssh/id_rsa and ~/.ssh/id_rsa.pub
If the key is password protected the formatting can only be
verified if the password is provided (--check_pass argument)
key verify pem
Verifies that ~/.ssh/id_rsa has PEM format
key verify ssh --pub
Verifies that ~/.ssh/id_rsa.pub has OpenSSH format
key verify pem --filename=~/.cloudmesh/foobar
Verifies if the private key located at ~/.cloudmesh/foobar
is password protected
key verify pem --filenam=~/.cloudmesh/foobar --check_pass
Request the password to the file, then checks if the
key is in proper PEM format
You may find the need to keep the values of your keys but
different encodings or formats. These aspects of your key can
also be changed using cloudmesh.
key reformat pem
Will reformat the ~/.id_rsa.pub key from PEM to OpenSSH
key reformat ssh
Will reformat the ~/.id_rsa.pub key from OpenSSH to PEM
key reformat --filename=~/.id_rsa --format=PKCS8
Will reformat the private key to PKCS8 format
Keys will be uploaded into cloudmesh database with the add
command under the given NAME. If the name is not specified the name
cloudmesh.profile.user is assumed.
key add NAME --source=ssh
adds the default key in ~/.ssh/id_rsa.pub
key add NAME --source=FILENAME
adds the key specified by the filename with the given name
key add NAME --git --username=username
adds a named github key from a user with the given github
username.
key set
adds the ~/.ssh/id_rsa.pub key with the name specified in
cloudmesh.profile.user.
It also sets the variable key to that user.

To list these keys the following list functions are provided.
key list --source=git [--username=USERNAME]

adds the ~/.ssh/id_rsa.pub key with the name specified in
cloudmesh.profile.user.
It also sets the variable key to that user.
Once the keys are uploaded to github, they can be listed
To list these keys the following list functions are provided.
key list --source=git [--username=USERNAME]
lists all keys in git for the specified user. If the
name is not specified it is read from cloudmesh.yaml
key list --source=ssh [--dir=DIR] [--output=OUTPUT]
lists all keys in the directory. If the directory is not
specified the default will be ~/.ssh
key list NAMES
lists all keys in the named virtual machines.
List command can use the [--output=OUTPUT] option
list the keys loaded to cloudmesh in the given format:
json, yaml, table. table is default. The NAME can be
specified and if omitted the name cloudmesh.profile.user
is assumed.
To get keys from the cloudmesh database the following commands
are available:
key delete NAMES
deletes the Named keys. This may also have an impact on groups
key rename NAME NEW
renames the key from NAME to NEW in the cloudmesh database.
Group management of keys is an important concept in cloudmesh,
allowing multiple users to be added to virtual machines while
managing the keys associated with them. The keys must be uploaded
to cloudmesh database with a name so they can be used in a
group. The --dryrun option executes the command without
uploading the information to the clouds. If no group name is
specified the group name default is assumed. If no cloudnamesh
are specified, all active clouds are assumed. active clouds
can be set in the cloudmesh.yaml file.
key group delete [GROUPNAMES] [NAMES] [--dryrun]
deletes the named keys from the named groups.
key group list [GROUPNAMES] [--output=OUTPUT]
list the key names and details in the group.
key group upload [GROUPNAMES] [CLOUDS] [--dryrun]
uploads the named groups to the specified clouds.
In some cases you may want to store the public keys in files. For
this reason we support the following commands.
key group add --group=GROUPNAME --file=FILENAME
the command adds the keys to the given group. The keys are
written in the files in yaml format.
key group export --group=GROUNAMES --filename=FILENAME
the command exports the keys to the given group. The keys are
written in the files in yaml format.
The yaml format is as follows:
cloudmesh:
keys:
NAMEOFKEY:
name: NAMEOFKEY
key: ssh-rsa AAAA..... comment
group:
- GROUPNAME
...
If a key is included in multiple groups they will be added
to the grouplist of the key

NAME The name of the key.
SOURCE db, ssh, all
OUTPUT The format of the output (table, json, yaml)

--dir=DIR the directory with keys [default: ~/.ssh]
--check_pass Flag where program query user for password
--filename=FILENAME the name and full path to the file
--nopass Flag indicating if the key has no password
--output=OUTPUT the format of the output [default: table]
--pub Indicates that the public key is passed in
--set_path Sets the cloudmesh encryption key path to
the full path of the generated keys
--source=SOURCE the source for the keys

Description:
Please note that some values are read from the cloudmesh.yaml
file. One such value is cloudmesh.profile.user
Management of public keys is an essential component of accessing
virtual machines in the cloud. There are a number of sources
where you can find public keys. This includes the ~/.ssh
directory and for example github. If you do not already have a
public-private key pair they can be generated using cloudmesh
key gen ssh
This will create the public-private keypair of ~/.ssh/id_rsa
and ~/.ssh/id_rsa.pub in OpenSSH format
key gen pem
This will create the public-private keypair of ~/.ssh/id_rsa
and ~/.ssh/id_rsa.pub in PEM format
key gen (ssh | pem) --filename=~/.cloudmesh/foobar
This will generate the public-private key pair of
~/.cloudmesh/foobar and ~/.cloudmesh/foobar.pub
key gen (ssh | pem) --filename=~/.cloudmesh/foobar --set_path
This will generate the keys as stated above, but it will
also set cloudmesh to use these keys for encryption.
Keys can also be verified for their formatting and passwords.
By default cloudmesh checks ~/.ssh/id_rsa and ~/.ssh/id_rsa.pub
If the key is password protected the formatting can only be
verified if the password is provided (--check_pass argument)
key verify pem
Verifies that ~/.ssh/id_rsa has PEM format
key verify ssh --pub
Verifies that ~/.ssh/id_rsa.pub has OpenSSH format
key verify pem --filename=~/.cloudmesh/foobar
Verifies if the private key located at ~/.cloudmesh/foobar
is password protected
key verify pem --filenam=~/.cloudmesh/foobar --check_pass
Request the password to the file, then checks if the
key is in proper PEM format
You may find the need to keep the values of your keys but
different encodings or formats. These aspects of your key can
also be changed using cloudmesh.
key reformat pem
Will reformat the ~/.id_rsa.pub key from PEM to OpenSSH
key reformat ssh
Will reformat the ~/.id_rsa.pub key from OpenSSH to PEM
key reformat --filename=~/.id_rsa --format=PKCS8
Will reformat the private key to PKCS8 format
Keys will be uploaded into cloudmesh database with the add
command under the given NAME. If the name is not specified the name
cloudmesh.profile.user is assumed.
key add NAME --source=ssh
adds the default key in ~/.ssh/id_rsa.pub
key add NAME --source=FILENAME
adds the key specified by the filename with the given name
key add NAME --git --username=username
adds a named github key from a user with the given github
username.
key set
adds the ~/.ssh/id_rsa.pub key with the name specified in
cloudmesh.profile.user.
It also sets the variable key to that user.
Once the keys are uploaded to github, they can be listed
To list these keys the following list functions are provided.
key list --source=git [--username=USERNAME]
lists all keys in git for the specified user. If the
name is not specified it is read from cloudmesh.yaml
key list --source=ssh [--dir=DIR] [--output=OUTPUT]
lists all keys in the directory. If the directory is not
specified the default will be ~/.ssh
key list NAMES
lists all keys in the named virtual machines.
List command can use the [--output=OUTPUT] option
list the keys loaded to cloudmesh in the given format:
json, yaml, table. table is default. The NAME can be
specified and if omitted the name cloudmesh.profile.user
is assumed.
To get keys from the cloudmesh database the following commands
