Contributing Cloud Test Resources
|

#################################

|
OpenStack utilizes a "project gating" system based on `Zuul
|
|
<http://docs.openstack.org/infra/zuul/>`_ to ensure that every change
|
|
proposed to any OpenStack project passes tests before being added to
|
|
its source code repository. Each change may run several jobs which
|
|
test the change in various configurations, and each job may run
|
|
thousands of individual tests. To ensure the overall security of the
|
|
system as well as isolation between unrelated changes, each job is run
|
|
on an OpenStack compute instance that is created specifically to run
|
|
that job and is destroyed and replaced immediately after completing
|
|
that task.
|
|
|
|
This system operates across multiple OpenStack clouds, making the
|
|
OpenStack project infrastructure itself a substantial and very public
|
|
cross-cloud OpenStack application.
|
|
|
|
The compute instances used by this system are generously donated by
|
|
organizations that are contributing to OpenStack, and the project is
|
|
very appreciative of this.
|
|
|
|
By visiting this page, you can see the system in action at any time:
|
|
|
|
http://status.openstack.org/zuul/
|
|
|
|
You'll see every job that's running currently, as well as some graphs
|
|
that show activity over time. Each of those jobs is running on its
|
|
own compute instance. We create and destroy quite a number of those
|
|
each day (most compute instances last for about 1 hour).
|
|
|
|
Having resources from more providers will help us continue to grow the
|
|
project and deliver test results to developers quickly. OpenStack has
|
|
long-since become too complicated for developers to effectively test in
|
|
even the most common configurations on their own, so this process is
|
|
very important for developers.
|
|
|
|
If you have some capacity on an OpenStack cloud that you are able to
|
|
contribute to the project, it would be a big help. This is what we
|
|
need:
|
|
|
|
* Nova and Glance APIs (with the ability to upload images)
|
|
* A single instance with 500GB of disk (via Cinder is preferred,
|
|
local is okay) per cloud region for our region-local mirror
|
|
|
|
Each test instance requires:
|
|
|
|
* 8GB RAM
|
|
* 8vCPU at 2.4GHz (or more or less vCPUs depending on speed)
|
|
* A public IP address (IPv4 and/or IPv6)
|
|
* 80GB of storage
|
|
|
|
In a setting where our instances will be segregated, our usage
|
|
patterns will cause us to be our own noisy neighbors at the worst
|
|
times, so it would be best to plan for little or no overcommitment.
|
|
In an unsegregrated public cloud setting, the distribution of our jobs
|
|
over a larger number of hypervisors will allow for more
|
|
overcommitment.
|
|
|
|
Since there's a bit of setup and maintenance involved in adding a new
|
|
provider, a minimum of 100 instances would be helpful.

|
Since we continuously use the OpenStack APIs and are familiar with how
|
|
they should operate, we occasionally discover potential problems with
|
|
contributing clouds before many of their other users (or occasionally
|
|
even ops teams). In these cases, we work with contacts on their
|
|
operations teams to let them know and try to help fix problems before
|
|
they become an issue for their customers.
|
|
|
|
We collect numerous metrics about the performance of the clouds we
|
|
utilize. From these metrics we create dashboards which are freely
|
|
accessible via the Internet to help providers see and debug
|
|
performance issues.

The OpenStack Foundation has identified Infrastructure Donors as a
|
|
special category of sponsoring organization and prominately identifies
|
|
them on this page: https://www.openstack.org/foundation/companies/
|
|
|
|
If this sounds interesting, and you have some capacity to spare, it
|
|
would be very much appreciated. You are welcome to contact the
|
|
Infrastructure team on our public mailing list at
|
|
<openstack-infra@lists.openstack.org>, or in our IRC channel,
|
|
`#openstack-infra` on Freenode. You are also welcome to contact the
|
|
Infrastructure Project Team lead privately at <fungi@yuggoth.org> or
|
|
`fungi` on Freenode.
