Description:
Cluster Management
cluster list
list the clusters
cluster create <name> --count=<count> --ln=<LoginName> [options...]
Start a cluster of VMs, and each of them can log into all others.
CAUTION: you sould do some default setting before using this command:
1. select cloud to work on, e.g. cloud select india
2. activate the cloud, e.g. cloud on india
3. set the default key to start VMs, e.g. key default [NAME]
4. set the start name of VMs, which is prefix and index, e.g. label --prefix=test --id=1
5. set image of VMs, e.g. default image
6. set flavor of VMs, e.g. default flavor
Also, it is better to choose a unused group name
cluster show <name>
show the detailed information about the cluster VMs
cluster remove <name> [--grouponly]
remove the cluster and its VMs, if you want to remove the cluster(group name)
without removing the VMs, use --grouponly flag
Arguments:
<name> cluster name or group name
Options:
--count=<count> give the number of VMs to add into the cluster
--ln=<LoginName> give a login name for the VMs, e.g. ubuntu
--cloud=<CloudName> give a cloud to work on
--flavor=<flavorName> give the name of the flavor
--flavorid=<flavorId> give the id of the flavor
--image=<imgName> give the name of the image
--imageid=<imgId> give the id of the image
--force if a group exists and there are VMs in it, the program will
ask user to proceed or not, use this flag to respond yes as
default(if there are VMs in the group before creating this
cluster, the program will include the exist VMs into the cluster)
--grouponly remove the group only without removing the VMs, otherwise
cluster remove command will remove all the VMs of this cluster
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
