OpenStack Configuration Guide
=============================
Before The First Deployment
---------------------------
When executing deploy.sh, before doing real deployment, Daisy utilizes
Kolla's service configuration functionality [1] to specify the following
changes to the default OpenStack configuration which comes from Kolla as
default.
a) If is it is a VM deployment, set virt_type=qemu amd cpu_mode=none for
nova-compute.conf.
b) In nova-api.conf set default_floating_pool to the name of the external
network which will be created by Daisy after deployment for nova-api.conf.
c) In heat-api.conf and heat-engine.conf, set deferred_auth_method to
trusts and unset trusts_delegated_roles.
Those above changes are requirements of OPNFV or environment's
constraints. So it is not recommended to change them. But if the user
wants to add more specific configurations to OpenStack services before
doing real deployment, we suggest to do it in the same way as deploy.sh
do. Currently, this means hacking into deploy/prepare.sh or
deploy/prepare/execute.py then add config file as described in [1].
Notes:
Suggest to pass the first deployment first, then reconfigure and deploy
again.
After The First Deployment
--------------------------
After the first time of deployment of OpenStack, its configurations can
also be changed and applied by using Kolla's service configuration
functionality [1]. But user has to issue Kolla's command to do it in this
release:
.. code-block:: console
cd /home/kolla_install/kolla-ansible/
./tools/kolla-ansible reconfigure -i /home/kolla_install/kolla-ansible/ansible/inventory/multinode
