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
[akrzos@bithead ~]$ sudo systemctl enable sshd
[akrzos@bithead ~]$ sudo systemctl start sshdMap 127.0.0.2 to your local host
[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.localdomain6Create a Quickstart cloud
Download quickstart.sh
[akrzos@bithead ~]$ curl -O https://raw.githubusercontent.com/openstack/tripleo-quickstart/master/quickstart.shInstall dependencies
[akrzos@bithead ~]$ bash quickstart.sh --install-depsCreate 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 undercloud image, enabling telemetry, and the networking setup. The nodes configuration file defines the amount of resources for your virtual overcloud including node count, 3 examples are included here.

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
[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.10You can now access the overcloud's external/public api endpoints from your local machine and install Browbeat for benchmarking against it.
Setup Browbeat with Rally 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. Follow the next commands in order to setup Browbeat with Rally against your local quickstart cloud.
