Chapter 8. Performing Tasks after Overcloud Creation
This chapter explores some of the functions you perform after creating your Overcloud of choice.
8.1. Creating the Overcloud Tenant Network
The Overcloud requires a Tenant network for instances. Source the
overcloud and create an initial Tenant network in Neutron. For example:
$ source ~/overcloudrc $ neutron net-create default $ neutron subnet-create --name default --gateway 172.20.1.1 default 172.20.0.0/16
This creates a basic Neutron network called
default. The Overcloud automatically assigns IP addresses from this network using an internal DHCP mechanism.
Confirm the created network with
neutron net-list:
$ neutron net-list +-----------------------+-------------+----------------------------------------------------+ | id | name | subnets | +-----------------------+-------------+----------------------------------------------------+ | 95fadaa1-5dda-4777... | default | 7e060813-35c5-462c-a56a-1c6f8f4f332f 172.20.0.0/16 | +-----------------------+-------------+----------------------------------------------------+
