Developing against Quickstart
=============================
This document helps you with creating a Tripleo Virtual Cloud on your local machine to assist
with developing/testing Browbeat.
Why use Quickstart?
-------------------
Tripleo-Quickstart enables us to have an entire tiny cloud to run Browbeat against. It gives
you a virtual Undercloud, virtual Overcloud Controller and Computes and other virtual nodes as
well. This allows you (with understood limitations) to run Browbeat, test commits, or develop
actively with new code without requring a full set of hardware or to run code through CI.
Limitations
-----------
Since everything is virtualized on your local hardware, any performance results are subject to the
limitations of your hardware as well as performance behaving with "noisy neighbors". This is only
recommended for testing Browbeat and/or gaining familiarity with OpenStack Tripleo Clouds.
Hardware Requirements
---------------------
Memory will most likely be your limitation:
* 16GiB Memory+Swap
* Undercloud, 1 Controller
* 32GiB Memory is recommended
* Undercloud, 1 Controller
* Undercloud, 1 Controller, 1 Compute
* Undercloud, 3 Controllers
4 physical cpu cores is recommended with at least 50GB of free disk space ideally on an SSD.
Localhost Preparation
---------------------
Ensure that sshd is running on your localhost
.. code-block:: none
[akrzos@bithead ~]$ sudo systemctl enable sshd
[akrzos@bithead ~]$ sudo systemctl start sshd
Map 127.0.0.2 to your local host
.. code-block:: none
[akrzos@bithead ~]$ sudo cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 127.0.0.2
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
Create a Quickstart cloud
-------------------------
Download quickstart.sh
~~~~~~~~~~~~~~~~~~~~~~
.. code-block:: none
[akrzos@bithead ~]$ curl -O https://raw.githubusercontent.com/openstack/tripleo-quickstart/master/quickstart.sh
Install dependencies
~~~~~~~~~~~~~~~~~~~~
.. code-block:: none
[akrzos@bithead ~]$ bash quickstart.sh --install-deps
Create Configuration and Nodes YAML Files
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
For this usage of Tripleo-quickstart, there are two configuration files to build a cloud,
quickstart_config.yml and quickstart_nodes.yml configuration file. Quickstart_config.yml contains
some basic options you may configure for your under/over clouds including ssl, cached image urls,
enabling telemetry, and the networking setup. The nodes configuration file defines the
amount of resources for your virtual overcloud including node count, Three examples are included
here.

Run quickstart.sh playbooks
You can change version of OpenStack (Ex. newton, ocata, master) you need by editing the `release`
yaml parameter in quickstart_config.yaml (above).
::
time bash quickstart.sh -v -c quickstart_config.yml -N quickstart_nodes.yml -I -t all -p quickstart.yml -T all -X 127.0.0.2
::
time bash quickstart.sh -v -c quickstart_config.yml -N quickstart_nodes.yml -I -t all -p quickstart-extras-undercloud.yml -T none 127.0.0.2
::
time bash quickstart.sh -v -c quickstart_config.yml -N quickstart_nodes.yml -I -t all -p quickstart-extras-overcloud-prep.yml -T none 127.0.0.2
::
time bash quickstart.sh -v -c quickstart_config.yml -N quickstart_nodes.yml -I -t all -p quickstart-extras-overcloud.yml -T none 127.0.0.2
If all 4 playbooks completed without errors, you should have a local tripleo quickstart cloud. In
order to validate, I would recommend ssh-ing into the Undercloud and issuing various openstack cli
commands against the overcloud to verify the health of your quickstart-deployment.
Connecting to your Undercloud/Overcloud from your local machine
---------------------------------------------------------------
Create a vlan10 for external network access
.. code-block:: none
[root@bithead network-scripts]# cat ifcfg-brovc.10
DEVICE=brovc.10
ONBOOT=yes
HOTPLUG=no
NM_CONTROLLED=no
VLAN=yes
IPADDR=172.21.0.2
NETMASK=255.255.255.0
BOOTPROTO=none
MTU=1500
[root@bithead network-scripts]# ifup brovc.10
You can now access the overcloud's external/public api endpoints from your local machine and
install Browbeat for benchmarking against it.
Setup Browbeat against your Quickstart Cloud
--------------------------------------------
After you have your Quickstart cloud up and the networking connectivity working, you will want
to run Browbeat against it so you can begin contributing. Simply run the script in the utils folder
to install Browbeat for usage on the new Tripleo Quickstart cloud.
