Contributing Cloud Test Resources
Contributing Cloud Test Resources
OpenStack utilizes a "project gating" system based on 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:
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
- 8GB RAM, 8vCPU per test node (CPUs vary, the important thing is to be able to run devstack and tempest in about 1 hour)
- Public IP addresses
- A single instance with 300GB of disk (via Cinder is okay) per cloud region for our region-local mirror
Our current providers are each donating around 600 instances of the above types. 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.
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.
