Appendix A: Example test environment configuration
|

==================================================
|
|
|
|
Introduction
|
|
~~~~~~~~~~~~
|
|
|
|
This appendix describes an example test environment for a working
|
|
OpenStack-Ansible (OSA) deployment with a small number of servers.
|
|
|
|
This example environment has the following characteristics:
|
|
|
|
* One infrastructure (control plane) host (8 vCPU, 8 GB RAM, 60 GB HDD)
|
|
* One compute host (8 vCPU, 8 GB RAM, 60 GB HDD)
|
|
* One Network Interface Card (NIC) for each host
|
|
* A basic compute kit environment, with the Image (glance) and Compute (nova)
|
|
services set to use file-backed storage.
|
|
* Internet access via the router address 172.29.236.1 on the
|
|
Management Network

Network configuration
|
|
~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
Network CIDR/VLAN assignments
|
|
-----------------------------
|
|
|
|
The following CIDR and VLAN assignments are used for this environment.
|
|
|
|
+-----------------------+-----------------+------+
|
|
| Network | CIDR | VLAN |
|
|
+=======================+=================+======+
|
|
| Management Network | 172.29.236.0/22 | 10 |
|
|
+-----------------------+-----------------+------+
|
|
| Tunnel (VXLAN) Network| 172.29.240.0/22 | 30 |
|
|
+-----------------------+-----------------+------+
|
|
| Storage Network | 172.29.244.0/22 | 20 |
|
|
+-----------------------+-----------------+------+
|
|
|
|
IP assignments
|
|
--------------
|
|
|
|
The following host name and IP address assignments are used for this
|
|
environment.
|
|
|
|
+------------------+----------------+-------------------+----------------+
|
|
| Host name | Management IP | Tunnel (VxLAN) IP | Storage IP |
|
|
+==================+================+===================+================+
|
|
| infra1 | 172.29.236.11 | | |
|
|
+------------------+----------------+-------------------+----------------+
|
|
| compute1 | 172.29.236.12 | 172.29.240.12 | 172.29.244.12 |
|
|
+------------------+----------------+-------------------+----------------+
|
|
| storage1 | 172.29.236.13 | | 172.29.244.13 |
|
|
+------------------+----------------+-------------------+----------------+

|
Host network configuration
|
|
--------------------------
|
|
|
|
Each host will require the correct network bridges to be implemented. The
|
|
following is the ``/etc/network/interfaces`` file for ``infra1``.
|
|
|
|
.. note::
|
|
|
|
If your environment does not have ``eth0``, but instead has ``p1p1`` or
|
|
some other interface name, ensure that all references to ``eth0`` in all
|
|
configuration files are replaced with the appropriate name. The same
|
|
applies to additional network interfaces.
|
|
|
|
.. literalinclude:: ../../etc/network/interfaces.d/openstack_interface.cfg.test.example
|
|
|
|
Deployment configuration
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
Environment layout
|
|
------------------
|
|
|
|
The ``/etc/openstack_deploy/openstack_user_config.yml`` file defines the
|
|
environment layout.
|
|
|
|
The following configuration describes the layout for this environment.
|
|
|
|
.. literalinclude:: ../../etc/openstack_deploy/openstack_user_config.yml.test.example
|
|
|
|
Environment customizations
|
|
--------------------------
|
|
|
|
The optionally deployed files in ``/etc/openstack_deploy/env.d`` allow the
|
|
customization of Ansible groups. This allows the deployer to set whether
|
|
the services will run in a container (the default), or on the host (on
|
|
metal).
|
|
|
|
For this environment you do not need the ``/etc/openstack_deploy/env.d``
|
|
folder as the defaults set by OpenStack-Ansible are suitable.
|
|
|
|
User variables
|
|
--------------
|
|
|
|
The ``/etc/openstack_deploy/user_variables.yml`` file defines the global
|
|
overrides for the default variables
|
|
|
|
For this environment you do not need the
|
|
``/etc/openstack_deploy/user_variables.yml`` file as the defaults set by
|
|
OpenStack-Ansible are suitable.
