Description:
cms burn create --inventory=INVENTORY --device=DEVICE --name=NAME
Will refer to a specified cloudmesh inventory file (see cms help inventory).
Will search the configurations for NAME inside of INVENTORY and will burn
to DEVICE. Supports parameter expansion.
cms burn create --passwd=PASSWD
if the passwd flag is added the default password is
queried from the commandline and added to all SDCards
if the flag is omitted login via the password is
disabled and only login via the sshkey is allowed
Network
cms burn network list

cms burn firmware check
Checks if the firmware on the Pi is up to date
cms burn firmware update
Checks and updates the firmware on the Pi
cms burn install
Installs a program to shrink img files. THis is
useful, after you created a backup to make the
backup smaller and allow faster burning in case of
recovery
This command is not supported on MacOS
cms burn load --device=DEVICE
Loads the sdcard into the USB drive. Thi sis similar to
loading a cdrom drive. It s the opposite to eject
cms burn format --device=DEVICE
Formats the SDCard in the specified device. Be
careful it is the correct device. cms burn info
will help you to identifying it
cms burn mount [--device=DEVICE] [--os=OS]
Mounts the file systems available on the SDCard
cms burn unmount [--device=DEVICE] [--os=OS]
Unmounts the mounted file systems from the SDCard
cms burn info [--device=DEVICE]
Provides useful information about the SDCard
cms burn image versions [--refresh] [--yaml]
The images that you like to burn onto your SDCard
can be cached locally with the image command. The
available images for the PI can be found when
using the --refresh option. If you do not specify
it it reads a copy of the image list from our
cache
cms burn image ls
Lists all downloaded images in our cache. You can
download them with the cms burn image get command
cms burn image delete [--image=IMAGE]
Deletes the specified image. The name can be found
with the image ls command
cms burn image get [--url=URL] [TAG...]
Downloads a specific image or the latest
image. The tag are a number of words separated by
a space that must occur in the tag that you find
in the versions command
cms burn backup [--device=DEVICE] [--to=DESTINATION]
This command requires you to install pishrink previously with
cms burn install
Backs up a SDCard to the given location.
cms burn copy [--device=DEVICE] [--from=DESTINATION]
Copies the file form the destination on the SDCard
this is the same as the SDCard command. we will in
future remove one
cms burn shrink [--image=IMAGE]
Shrinks the size of a backup or image file that
is on your local file system. It can only be used
for .img files
This command is not supported on MacOS.
cms burn create [--image=IMAGE]
[--device=DEVICE]
[--hostname=HOSTNAME]
[--ip=IP]
[--sshkey=KEY]
[--blocksize=BLOCKSIZE]
[--passwd=PASSWD]
[--ssid=SSID]
[--wifipassword=PSK]
[--format]
This command not only can format the SDCard, but
also initializes it with specific values
cms burn sdcard [TAG...] [--device=DEVICE]
this burns the sd card, see also copy and create
cms burn set [--hostname=HOSTNAME]
[--ip=IP]
[--key=KEY]
[--mount=MOUNTPOINT]
[--keyboard=COUNTRY]
[--cmdline=CMDLINE]
Sets specific values on the sdcard after it
has ben created with the create, copy or sdcard
command
a --ssh is missing from this command
cms burn enable ssh [--mount=MOUNTPOINT]
Enables the ssh server once it is booted
cms burn wifi --ssid=SSID [--passwd=PASSWD] [--country=COUNTRY]
Sets the wifi ssid and password after the card
is created, copied, or the sdcard is used.
The option country option expects an ISO 3166-1
two digit country code. The default is "US" and
the option not required if suitable. See
https://en.wikipedia.org/wiki/ISO_3166-1 for other
countries.
cms burn check [--device=DEVICE]
Lists the parameters that were set
with the set or create command
Examples: ( \\ is not shown)
> cms burn create --image=2019-09-26-raspbian-buster-lite
> --device=/dev/mmcblk0
> --hostname=red[5-7]
> --ip=192.168.1.[5-7]
> --sshkey=id_rsa

Description:
add -- adds a resource to the resource inventory
list -- lists the resources in the given format
delete -- deletes objects from the table
clone -- copies the content of an existing object
and creates new once with it
set -- sets for the specified objects the attribute
to the given value or values. If multiple values
are used the values are assigned to the and
objects in order. See examples
map -- allows to set attributes on a set of objects
with a set of values
Examples:
cms inventory add x[0-3] --service=openstack
adds hosts x0, x1, x2, x3 and puts the string
openstack into the service column
cms inventory list
lists the repository
cms inventory set x[3-4] temperature to 32
sets for the resources x3, x4 the value of the

cms inventory set x[7-8] ip to 128.0.0.[0-1]
sets the value of x7 to 128.0.0.0
sets the value of x8 to 128.0.0.1
cms inventory set x1 services to bridge,kubernetes --listvalue
sets the value of x1 to [bridge, kubernetes]
The --listvalue option indicates the value set is a list
cms inventory clone x[5-6] from x3
clones the values for x5, x6 from x3
