Adding a compute host to a host aggregate
Before a host aggregate can be used by OpenStack Compute, you must first add hosts to the aggregate groups created.
Getting ready
To add a host to an aggregate, you will need the following information:
- The
openstack
command-line client - The
openrc
file containing appropriate credentials - The name or ID of the aggregate
- The name or ID of the host
For the following example, the required values are as follows:
- Host aggregate:
cookbook-ssd-hosts
- Compute host:
compute-01
How to do it…
The following process is used to add a host to a host aggregate:
- List hosts that are already in the aggregate:
openstack aggregate show cookbook-ssd-hosts
This will bring back an output like the following:
- Now add the specified compute host ...
