Usage:
cluster start CLUSTER_NAME
cluster list
cluster login CLUSTER_NAME
cluster stop CLUSTER_NAME
cluster create --count=<count>
--group=<group>
[--ln=<LoginName>]
[--cloud=<CloudName>]
[--image=<imgName>|--imageid=<imgId>]
[--flavor=<flavorName>|--flavorid=<flavorId>]
[--force]
Description:
Cluster Management
cluster create --count=<count> --group=<group> --ln=<LoginName> [options...]
<count> specify amount of VMs in the cluster
<group> specify a group name of the cluster, make sure it's unique
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, please make sure the group name of the cluster is unique
Options:
--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)
