Resource Pools¶
Add a New Resource Pool¶
Objective¶
I’d like to add a new resource pool of IP addresses so that I can assign a new IP to each node that gets provisioned.
Note
Resource Pools are simple key: value
YAML files.
Solution¶
Create the resource pool
# Go to your data_root - by default it's /usr/share/ztpserver
admin@ztpserver:~# cd /usr/share/ztpserver
# Create a resource pool file
admin@ztpserver:~# vi resources/mgmt_ip
192.168.0.2/24: null
192.168.0.3/24: null
192.168.0.4/24: null
192.168.0.5/24: null
192.168.0.6/24: null
192.168.0.7/24: null
192.168.0.8/24: null
192.168.0.9/24: null
192.168.0.10/24: null
Explanation¶
Resource Pool files are just key: value
files. The default value for each
key should be null
. This makes the key available for assignment. If you would
like to pre-assign a specific node with a particular key, then just put the
node’s node_id in place of null
. Resource Pools are analyzed when the
allocate(pool_name)
function is run from a definition. Note that you can
also use the allocate()
function to perform a lookup when a node has
already been assigned a key.
Clearing a Resource Pool¶
Objective¶
I’d like to reset the values of a resource pool so that all values return to
null
.
Solution¶
You can use the ztps command line to perform this action.
admin@ztpserver:~# ztps --clear-resources
Note
This will clear ALL resource pools
Explanation¶
Clearing all resource pools can be done via the command line on the ZTPServer.
The command will analyze data_root/resources
and any file that exists in
that directory that resembles a ZTPServer resource pool will be cleared.
