Internship ideas


To submit new ideas please consider creating a new page and use the Template:InternshipIdea (instructions are provided on that page) and you can see how a sample idea page would look like. The pages created with such template are listed on Category:Internship_idea.


List of Ideas for Internships

The OpenStack Foundation has multiple sources for internships, from Outreachy to Google Summer of Code and other opportunities. This page collects the ideas for candidate interns to work on.

Applicants may not have ever worked on FLOSS before and have different levels of competence. Since we have different programs, add here ideas that can be completed by inexperienced contributors, developers or other fields (marketing, communication, graphic design, and anything that may be useful for OpenStack and to include new people in this community).

Coding

OpenStack as a virtual Kubernetes node

Implement a virtual Kubernetes node that allows running containers/pods on OpenStack. Students applying to work on this will learn about Zun and Kubernetes, and will work on implemeting a whole new feature for Zun, which will include not only coding but also testing and documentation efforts. See https://github.com/virtual-kubelet/virtual-kubelet/issues/22 for more info on the requirement

Improve Cinder integration for Docker containers

Add support for Cinder volume multi-attach for Docker containers. Students willing to take this task will learn about Zun and Cinder. During the Ocata cycle a new flow for volume attaching has been implemented in Cinder. We want to make Zun leverage this new flow. Implementing this will require the student not only contribute with code, but also with testing and documentation for the feature. Check https://blueprints.launchpad.net/zun/+spec/cinder-volume-multi-attach for more details.

Help Implement Support for a Generic Backup Driver in Cinder

The goal is to create a generic backup driver that be used to turn any Cinder volume backend into a target for backups. This way, we won't need to implement specific backup driver for supported backends. Students picking this internship task will learn about Cinder and will be asked to contribute with testing and documentation of this feature. Refer to https://review.openstack.org/#/c/504099/1/specs/queens/generic-backup-implementation.rst for more detials

Image Lifecycle Support: 'Retired' images

Here's the problem. At any point in time, a cloud operator has a public image available of a popular operating system, say, "CentOS 7". The operator will keep the "CentOS 7" image updated with security and other bugfixes throughout the lifetime of the CentOS 7 operating system; in other words, there is not a single "CentOS 7" image, but a series of such images. The operator wants end users to use only the most recent image to boot new virtual machines, but also wants to keep the previous images available for those end users who need to do a rebuild or have a particular reason to use an older image and security patch it themselves. Currently there's no way to "retire" such images (that is, to make them hidden yet discoverable in a systematic way). Your mission, should you choose to accept it, would be to make this happen.

The exact details are still being worked out; in fact, you can join in the discussion on https://review.openstack.org/#/c/508133/ right now. Implementing this feature will touch multiple components of the Glance project: the API (to introduce the new field and filter on it), the database (new field plus migrations), and the python-glanceclient (to understand the new field). And of course you'll have to add tests for all this stuff. This is a great internship project because it is well-defined enough to be doable, touches enough components to be interesting, and is high-impact for users.

Difficulty Low to Medium (you don't need previous OpenStack experience, but you need to be self-motivated enough to learn the components of Glance and how they interact)

Eliminate Redundant Downloads of Uncached Images

An important component in the amount of time it takes to boot a new virtual machine is how long it takes to get the image being used from backend storage down to the host. To speed this up, Glance has optional caching middleware that for some back ends (specifically, OpenStack Swift), significantly improves performance. The problem is that the cache is kind of stupid, and in the scenario where someone wants to boot 1000 VMs from the same image, each request will discover that the image isn't cached, and will initiate a download from the storage backend, resulting in severely degraded performance.

There are some complexities to improving the caching middleware that are discussed in a Glance specification document: http://specs.openstack.org/openstack/glance-specs/specs/untargeted/glance/duplicate-downloads.html . In addition to coding, you will get exposure to working in an open-source community from the design phase through implementation, because your first task will be to re-propose the spec to the Glance community so that it can be reviewed and re-approved. (Don't worry, this won't drag on because it was already approved once; it is untargeted because the original developer was reassigned to a different project.) This is an interesting project that will touch several Glance components: the API server, the caching middleware, and the glance_store library. And, of course, you'll be adding good tests.

Difficulty Low to Medium (you don't need previous OpenStack experience, but you need to be self-motivated enough to learn the components of Glance and how they interact)

Transform legacy notifications to the new versioned framework in Nova

Help transforming legacy Nova notifications to a new versioned framework. Students applying for this task will learn about Nova and the oslo.messaging library, and will help transforming the legacy notifications of Nova to a proper versioned API using an already established framework. Check for more details on this page https://wiki.openstack.org/wiki/Nova/VersionedNotificationTransformation

Policy Testing

WIth all the system-scope work coming down the pipe and landing in Queens, we need to be prepared to rethink out test_v3_protection.py test module. This is the module responsible for making it so policies are doing what they should. Since we're adding a few new combinations with system scope, this should result in a test explosion that could be difficult to maintain and understand.

  • Can we come up with a way to flexibly test different policy cases
  • Refactor current coverage
  • Integration with Patrole

Flask support

We have a home-grown WSGI implementation when there are suitable frameworks to do that lifting for us. We can get rid of a wheel to maintain by moving to a framework and ditching the home-grown implementation. We've talked about moving to Flask for a while. The benefits would be less maintenance of a home-grown implementation.

Native SAML

Currently, federation requires the use of Apache plugins to do the SAML processing. We want to experiment with a piece of middleware that can go into keystone paste pipeline to process SAML according to specification. This will make federation easier to configure for deployers and it has the ability to reduce a mapping currently used in federation (assertions -> env var, env vars -> keystone mappings).

Make keystone a fully-fledged IdP

Currently, keystone can act as an IdP but only in a non-standard in-house-designed auth flow, not with WebSSO. We could implement the rest of the WebSSO standard in keystone. https://bugs.launchpad.net/keystone/+bug/1470205 This could be a good warm-up bug for either this or the Native SAML project: https://bugs.launchpad.net/keystone/+bug/1641625
