New page

== Prerequisites ==

* Install and configure CaaS (refer to [[Bright:CaaS Installation]]
* Create an Openstack user (Refer to "Openstack User Creation" section in the [[Bright:Openstack Installation]])
* Enable jumbo frame on the internal and vxlan networks and on the switch
* Create the flavor used as a default for nodes creation if not specified:
<syntaxhighlight>
[root@shadow-head ~] openstack flavor create --vcpus 1 --ram 1024 --disk 10 --ephemeral 10 --public m1.xsmall
</syntaxhighlight>

== Using CaaS ==

=== Create a cluster ===

A cluster can be created using the “os_cluster” command. In the following example:
* The values "CENTOS7u1" and "7.1-stable" are used because in buildmatic the "7.1-stable" version of Bright and the "CENTOS7u1" distribution were uploaded.
* The <CLUSTER_NAME> should be changed to a useful name, and
* The number of compute nodes to be deployed should be set for <NUMBER_OF_NODE>
<syntaxhighlight>
[root@shadow-head ~] os_cluster create <CLUSTER_NAME> CENTOS7u1 7.1-stable -n <NUMBER_OF_NODE>
</syntaxhighlight>

=== List the existing clusters ===
To list all the virtual head nodes, the command "os_cluster list" can be used. Optionally, a list can be filtered with the -e flag, using a regex.
<syntaxhighlight>
[root@shadow-head ~] os_cluster list
[root@shadow-head ~] os_cluster list -e test*
</syntaxhighlight>

=== Delete a cluster ===
<syntaxhighlight>
[root@shadow-head ~] os_cluster delete <CLUSTER_NAME>
</syntaxhighlight>

=== Create/Delete nodes ===
Once the virtual cluster is installed, the "os_node" command can be used to add/remove nodes to/from it.
<syntaxhighlight>
[root@shadow-head ~] os_node create <CLUSTER_NAME> --username root -p <root_pw_on_virtual_head> -n <NUMBER_OF_NODE>
[root@shadow-head ~] os_node create <CLUSTER_NAME> --username root -p <root_pw_on_virtual_head> -r node001..node003 #create nodes using a "range" syntax
[root@shadow-head ~] os_node create <CLUSTER_NAME> --username root -p <root_pw_on_virtual_head> -r node0[01-10] #create nodes using a "range" syntax
</syntaxhighlight>
