OpenStack Operators

  • Takeaways from the OpenStack Mid-Cycle Ops Meetup: first time’s the charm [1]
  • OpenStack Upgrading Tutorial: 11 pitfalls and solutions [2]

“No Open Core” in 2016 (continuing)

  • Continuing with discussions on Poppy in particular, Doug Hellmann raises that the Poppy team has done everything we’ve asked. The governance currently emphasizes on the social aspects of the project and community interactions. Tell the Poppy team they “are not OpenStack” even though they followed things is distressing.
  • Sean Dague mentions that solutions like Neutron have an open source solution. It may needed some work, but at least there was one open source solution for testing.
  • Dean Troyer brings up how we have things like Cinder with commerical products as storage drivers. Even without those storage drivers though, Cinder is still useful.
  • Poppy’s open source implementation option, OpenCDN is currently an abandoned project.

Upgrade Implications of Lots of Content in paste.ini

  • A set of Cross-origin resource sharing (CORS) patches came out recently [3], that adds a ton of content to paste.ini.
  • Paste.ini is a config that operators can change.
    • Large amounts of complicated things in there which may change in future releases is really problematic.
    • Deprecating content also is a challenge.
    • Why aren’t these options just the defaults of the CORS middlware?
      • Some projects like Ironic did request to not have headers prescribed, for eample, if Ironic is using something other than Keystone, different allowed headers would be required.
      • However, Keystone is defcore, so the default should be useful there first. Then be flexible to other auth options can go on top.
  • Where do we go from here?
    • Option 1: Implement as is, keep things consistent, fix them in Newton.
      • This is not fixable in Newton as it requires deprecating out for the next three releases.
    • Option 2: Try to fix it in Mitaka 2 of CORS middleware setting defaults and projects having the ability to override [4].
      • This will require patches against a bunch of projects [5]. Who can help?

Dropping KEYSTONE_CATALOG_BACKEND – Plus Update Your Devstack Plugins

  • Devstack has some half baked support for Keystone templated service catalog.
  • In an effort to clean up parts of Devstack, we’re dropping that [2].
  • This breaks everyone’s Devstack plugin that references the KEYSTONE_CATALOG_BACKEND variable.
  • This variable will be kept around until Newton development opens up.

  • Keystone is working towards allowing project_id in the service catalog [9].
  • Neutron is transitioning to project_id now.
  • The current Ansible OpenStack modules are using project [10].
  • OSLO Logging/Context are using project.
  • Full thread: http://lists.openstack.org/pipermail/openstack-dev/2016-February/086396.html

Proposal: Separate Design Summits From OpenStack Conferences

  • The OpenStack design summits originally started out as working events.
  • The OpenStack summits growing more marketing and sales focus, the contributors attending are often unfocused.
  • Some contributors submit talks for the conference, because their company says it’s the only way for them to attend the conference. Part of the reason for this is the cost of attending.
  • Thierry Carrez (who helps organize the design summit) explains that he has been working a solution for separation of the summit and the conference himself, and the Foundation is finalizing a strawman proposal that will be pushed to the community for comments soon.

Service Type vs. Project Name For Use In Headers

  • There’s a question of whether we should be using service type or project names in headers. Some reviews involving this [7][8][9][10].
  • We should be selecting things that better serve the API consumers and according to Dean Troyer the API working group is going in the right direction.
  • The service type as the primary identifier for endpoints and API services is well established, and is how the service catalog has and will always work. Service types therefore should be the way to go.
  • Full thread: http://lists.openstack.org/pipermail/openstack-dev/2016-January/085145.html

OpenStack Ansible Without Containers

  • Gyorgy annouces a new installer for OpenStack under GPLv3 using Ansible, but without containers.
    • Reasons for another installer since we already have the OpenStack Ansible project and Kolla:
      • Containers adding unnecessary complexity.
      • Packages: avoid mixing pip and distributor packages. Distributor packages includes things like init scripts, proper system users, upgrade possibilities, etc.
        • Kevin Carter mentions that these benefits are actually also included with the OpenStack Ansible project.
  • Without containers, upgrading a single controller can be tricky and disruptive since you have to upgrade every service at the same time. Rollbacks are also easier.
  • OpenStack Ansible project can already today do deployment without containers using the is_metal=true variable.

“No Open Core” in 2016

  • Before OpenStack had a name, the “four opens” principles were created to define how we operate as a community.
  • In 2010 when OpenStack started, it was different from other open source cloud platforms (Eucalyptus) which followed open core strategy of producing a crippled community edition and an “enterprise version”.
  • Today we have a non-profit independent foundation, which cannot do an “enterprise edition”.
    • Today member companies build “enterprise products” on top of the apache licensed upstream project. Some are drivers that expose functionality in proprietary components.
  • What does it mean to “not do open core” in 2016? What is acceptable and what’s not?
  • Thierry Carrez believes it’s time to refresh this of what is an acceptable official project in OpenStack.
    • It should have a fully-functional production grade open source implementation
    • If you need proprietary software of commercial entity to fully use the project, then it should not be accepted in OpenStack as an official project.
      • These projects can still be non-official projects and still be hosted by OpenStack infrastructure.
  • Doug Hellmann brings up Poppy [11] which is applying to be an official OpenStack project.
    • A wrapper to content delivery networks, but there is no open source solution.
    • Is this something that can be an official project, or is open core?
  • Full thread: http://lists.openstack.org/pipermail/openstack-dev/2016-February/085855.html

The Trouble with Names

  • A few issues have crept up recently with the service catalog, API headers, API end points, and even similarly named resources in different resources (e.g. backup), that are all circling around a key problem. Distributed teams and naming collision.
  • Each project has a unique name that is ensured by their git repository in the OpenStack namespace.
  • There’s a desire to replace project names with generic names like nova/compute in:
    • service catalog
    • api headers
  • Options we have are:
    • Use the code names we already have: nova, glance, swift, etc.
      • Upside: collision problem solved.
      • Downside: You need a secret decoder ring to know what a project does.
    • Have a registry of common names.
      • Upside: we can safely use common names everywhere and not fear collision down the road.
      • Downside: yet another contention point.
  • Approvals by the various people in the community to have a registry of the common names. Maybe in the governance projects.yaml file [12]?
    • This list does include only the official projects by the technical committee, therefore only those projects can reserve the common names.
  • OpenStack Client has already encoded some of these common names to projects [13].
  • Full thread: http://lists.openstack.org/pipermail/openstack-dev/2016-February/085748.html

Announcing Ekko – Scalable Block-Based Backup for OpenStack

  • The goal of Ekko is to provide incremental block-level backup and restore of Nova instances.
  • Two place with overlapping goals:
    • Cinder volume without having the incremental backups be dependent.
    • Nova instances
      • OpenStack Freezer today leverages Nova’s snapshot feature.
      • Ekko would leverage live incremental block-level backup of a nova instance.
  • Jay Pipes begins the discussion on the two projects (Freezer and Ekko) working together to make sure their REST API endpoints are not overlapping. Having two APIs for performing backups that are virtually identical is not good.
  • The creator of Ekko sees the reason for another backup project because of “actual implementation and end results are wildly different” even if they are the same API call.
  • Jay doesn’t like that today all the following endpoints exist:
    • Freezer’s /backups
    • Cinder’s /{tenant_id}/backups
  • Having these endpoints make for bad user experience and is just confusing.
  • The current governance model does not prevent competition of projects. So if two projects overlap in API endpoints, there should be an attempt in collaboration.
  • Full thread: http://lists.openstack.org/pipermail/openstack-dev/2016-January/084739.html

Technical Committee Highlights January 22, 2016

Upstream development track – please submit

We’ll have an “Upstream development” track at the Austin Summit. It will happen on the Monday, before the Design Summit starts. This is a classic Summit conference track with recorded videos, so we want polished proposals for this track. We expect these to include general communication about development process changes, new features in a central project that need adoption in other projects, corner use cases that may need support from development, developer-oriented infra talks and upstream development best practices. To propose a talk for this track, use the Summit proposal system, select Upstream development, and meet the February 1st deadline.

Our mission

The OpenStack overall mission has stood proudly for years now, and is due for an update to increase focus on cloud consumers rather than solely on cloud builders. So we have proposed an amendment to the original mission. You can read the current and proposed new mission on governance.openstack.org.

And now, even more doc

In a clarification effort, we pushed the definition of the 4 opens, as well as clarified OpenStack licensing requirements as reference documents under the governance repository. Previously those were maintained in oral tradition, the wiki, or left as an exercise to the reader of the Foundation bylaws. You can now find them published (like all Technical Committee resolutions and reference information) on the governance website.

The names are here! The names are here!

The N and O releases directly after Mitaka will be Newton and Ocata. For the Austin Summit, the tie-in is to the “Newton House”, located at 1013 E. Ninth Street in Austin, Texas. It’s listed on the National Register of Historic Places. For the Barcelona Summit, know that Ocata is a beach about 20 minutes north of Barcelona by train.

Newton House (Austin,TX)

Clarifying licensing requirements

A new governance page clarifies guidelines for licensing for projects in and around OpenStack.  We want to raise awareness and highlight that page for future reference. In the subset of OpenStack projects that may be included in a Defcore trademark program, the project must be licensed under Apache Software License v2, ASLv2. Libraries and software built in the OpenStack infrastructure system should use OSI-approved licenses that do not restrict distribution of the consuming project. Read more on the governance website.

Stabilization Cycles: Elaborating on the Idea To Move It Forward

  • At the Tokyo summit, the OpenStack Development Theme session, in which people discuss overall focus in shared efforts, having cycles to stabilize projects was brought up.
  • A project could decide to spend some percentage of time of the cycle on focusing on bug fixing, review backlog, refactoring, instead of entirely on new features.
  • Projects are already empowered to do this, however, maybe the TC could work on formalizing this process so that teams have a reference when they want to.
  • Some contributors from the summit feel they need the Technical Committee to take leadership on this, so that they can sell it back to their companies.
  • Another side of discussion, healthy projects should naturally come up with bursts of feature additions and burst of repaying technical debt continuously.
    • Imposing specific periods of stabilization prevents reaching that ideal state.

You Almost Never Need to Change Every Repository

  • There have been a lot of patches that tweak the same thing across many, many repositories.
  • Standardizations are great, but if you’re making the same change to more than a few repositories, we should be looking at another way to have that change applied.
  • If you find yourself making the same change over and over in a lot of projects, start a conversation on the dev mailing list first.

Release Countdown For Week R-11, Jan 18-22

  • Focus:
    • Next week is the second milestone for the Mitaka cycle.
    • Major feature work should be making good process, or be re-evaluated to see it really needs to land this cycle.

What’s next for application developer guides?

Summary

This month, the developer.openstack.org site gets a new look and changes its source tooling. Read on for details about how these changes affect your project team.

Why are we changing the developer.openstack.org site?

You might know that the developer.openstack.org site documents over 900GET/PUT/POST/DELETE/PATCH calls for a dozen OpenStack services already on the developer.openstack.org site. As a couple of the keynote speakers in Tokyo so elegantly put it, the trustworthiness and consistency of the OpenStack APIs influenced their decision to run their business workloads in an OpenStack cloud.

Those interfaces need docs, lots of docs, and not only reference docs. While it takes a huge effort to maintain accurate references, we also need to document API usage and scenarios.

Now that we’ve written both an API Guide and a “Writing your first OpenStack application” tutorial, we want the site to be the go-to location for app devs, product developers, and anyone who needs to unlock the power of their OpenStack infrastructure.

In this release, the docs’ platform introduces tooling that lets you migrate from WADL to Swagger and integrate RST-sourced documentation with the API reference documentation. The “why” analysis is clear: we must community-source this info and make it easy to maintain and update so that users can trust it enough to bet their workloads on it.

Later on, this post answers the “how” questions.

Why all these changes at this point in the release?

Well, we haven’t had to release the API documentation like we release services documentation. We have done a lot of maintenance on the site, with bug fixing and so on. But it’s time to take the leap. Last release we made a proof-of-concept. This release we unleash a solution that helps us make incremental progress toward our goals.

How do you keep your API docs updated after January 16th?

On January 16th, we’ll migrate the Images API WADL and DocBook files to Swagger and RST files. Then we’ll test the build process and the content itself to validate the migration.

After testing, we will migrate the files for these services:

  • Identity
  • Compute
  • Images
  • Networks
  • Block Storage
  • Object Storage

Then, the remaining services can migrate their files by using the validated tooling.

If you do provide an OpenStack API service, read on.

For the nova project, place your how-to and conceptual articles in the api-guide folder in the nova repository. Other projects can mimic these patches that created an api-guide and build jobs for the Compute api-guide. You continue to update reference information in the openstack/api-site repo. However, the source files have changed.

With this release, you can embed annotations in your source code if you want to generate the reference information. Here’s an example patch from the nova project. Because we haven’t had a project do this yet completely, the build jobs still need to be written.

If your project already has WADL files, they will be migrated to Swagger files and stored in the api-site repository. The WADL files will be deleted; you can retrieve them from Git.

If your project does not have a WADL file, then you write Swagger plus RST to document your API calls, parameters, and reference information. You can generate Swagger from annotations or create Swagger from scratch that you store in the api-site repository. You should review, store, and build RST for conceptual or how-to information from within your project team’s repository.

All projects should use this set of API documentation guidelines from the OpenStack API working group any time their service has a REST API. This document tells you what and how much to write. If you follow the suggested outline, your API guide will be accurate and complete.

After the source files and build jobs exist, the docs are built to developer.openstack.org.

Where can I get help for my project’s API Guides?

These specifications describe the details: Application Developer Guides and Rework API Reference Information.

You can ask questions in #openstack-sdks or #openstack-docs on IRC. We await those magical API docs fairies who grant wishes, but in the meantime but we can point you in the right direction and give you the tools for your quest.

What if I still have questions?

Contact me, Anne Gentle, by email or IRC and I’ll get back to you as soon as possible.

I’m eager to enable our audience with great user-centric docs and hope that you’ll join us as we fulfill the vision.

    • Identify work that needs to be completed before the M-2 tag.
    • Release liaisons responsibilities are being updated. Provide comments for questions or concerns [4].
  • Important Dates:
    • Mitaka 2: Jan 19-21
    • Release schedule [5].

Re-introduce Twisted to global-requirements

  • A change in global-requirements introduces mimic, an http server that can mock various APIs.
  • Mimic depends on twisted, which in the past was removed in favor of Eventlet to avoid developers having to know multiple frameworks [5].
  • Jim Rollenhagen explains Ironic’s need for Mimic:
    • To do functional tests, not unit tests which they could do with requests-mock.
    • To bring up a less expensive Ironic environment for doing these tests.
  • Jay Pipes notes:
    • This is another way to introduce a larger surface area of bugs to creep in since you have keep Mimic up-to-date with the real interfaces.
    • There’s not a clear value in the advantage  of functional tests of a client that calls a fake HTTP API versus unit tests of a client that simply uses requests-mock.

Stable Meeting Time Proposal

DocImpact vs. Reno

  • Sean notes a new job on all Nova changes that is processing commit messages [5].
  • UpgradeImpact got dropped for having an upgrade comment in Reno.
  • Instead of DocImpact, SecurityImpact in commit messages, new special sections using Reno will be created that trigger creating bugs and sending out emails like today. The hope is for better quality in these notifications.
