ONS NA 2019 Un-Conference - Leverage OPNFV Test Frameworks
Please note this un-conference discussion on Fri 4/5 15:10
Short Description: Explore opportunities for your LFN project to accelerate development of test frameworks, tools and methods through collaboration with OPNFV.
Detailed Description: OPNFV has developed significant functional and performance test assets including frameworks, tools, methods, test cases and test data. For an overview of the OPNFV Test Ecosystem refer to https://docs.opnfv.org/en/stable-gambia/testing/ecosystem/overview.html. The significant investments in OPNFV test projects and related activities could be leveraged by other LFN projects that require testing of integrated upstream ingredients and platforms. This discussion is to brainstorm about how to reuse existing work and artifacts so that we do not reinvent proverbial wheels in this arena. All ideas and input are welcome!

On the other hand, it is not always easy to list up all the possible use cases and requirements to be supported by a blueprint when it's proposed. Also, it is necessary to energize the community by providing a mechanism that is easy to accept various proposals. Therefore, the community needs to be able to update existing blueprint specification templates when necessary. Major triggers of such update are: A) Major/minor version update of a software component included in a given blueprint specification template. Example: Ubuntu 18.04.1 -> 18.04.2 B) Newer generation of a hardware component included in a given blueprint specification template. Example: Dell R740 -> R750 C) Proposal of new use cases and requirements/test cases which could be solved by updating an existing blueprint specification template through feature updates and/or template options updates. Example: Lower latency Network Cloud Software updates (A) can be verified and incorporated as the update to the existing blueprint spec template through an appropriate CI/CD mechanism. Hardware renewal (B) can also be done in the same way if anyone can contribute to bring those to CI/CD labs. New proposals (C) can be handled in the following way: 1) Contributor who are going to propose it needs to explain clear use case(s) and its requirements (i.e. POD and test cases). 2) If the community has an existing blueprint specification template (here assume BPT-A 1.0) which can solve some use cases and requirements that is not too far from the proposed ones, then the community can treat the proposal as potential update of the existing blueprint spec template (BPT-A 1.1 or 2.0, depending of versioning policy). If not, the community should consider to make another blueprint spec template (BPT-B 1.0). The point is that we should not make too many numbers of blueprint spec templates for the sake of the community maintenance and market value. Therefore, new proposal needs to be compared to the existing ones and only when it’s not close at all to any, we can consider making new blueprint spec templates.

Nor would I see specific functional components (2) developed by the Akraino community as ‘blueprints’ either.
I think using the term blueprint for everything tends to make the term too broad. The term blueprint in common parlance is taken to mean the definition of how to build something (e.g. a building – a house or a shed etc). I could of course be expanded to encompass more (like a test blueprint) but would suggest we keep Akraino blueprints to be more specific and not include functionality or test schedules.
Rather I propose a blueprint be used to classify a set of options that cab result in distinct POD deployments. The term ‘Network Clod blueprint’ would be used as such.

Akraino Mail Lists Update - ACTION REQUIRED
Akraino Community, In order to facilitate future discussions in clearly delineated forums utilizing open source project best practices we have made changes to the mail lists available for this community. Please review below the lists available and ensure you subscribe to the lists you are interested in by adding yourself to the applicable subgroups.
The main@... list will remain available but we recommend using this list extremely sparingly, for top-level milestone or critical announcements as the messages will hit all subscribers of all subgroups. As the Akraino project grows and scales we can certainly add additional lists but we’d like to first establish a proper foundation and thoughtfully build from there. If you have any questions, please reach out. Thank you,

Hope the project can agree on a policy around such selective backporting (vs. carrying out-of-tree patches).
Agree there may be a need to build images. Should probably be left to the respective Blueprint projects to decide how to build them, as each project may have tooling that's more "native" to them.

Re: Akraino Charter

Hi Frank,
On this:
“ - Is Akraino look to build the images/containers? Or limit the scope to installers, starting with Airship? If so, which sister project(s) going to build binary images suitable for Airship? Could you maybe elaborate why you feel it matters whether building images is part of the project or not?
“ I see some projects applying patches (patches that are created in upstream) to their current release instead of taking latest release. This requires capability of building binaries & packages.
Even otherwise, there are some upstream projects don’t create binary images or images in a way that is required.
For example, Openstack-kolla and Openstack-helm projects can be considered as sister projects to Airship as Kolla project creates container images for each openstack service and pushes them to dockerhub. Openstak-helm project is the home for helm charts which help in deploying them. I guess Airship installer requires them in containers and helm charts.
Some projects such as libvirtd, ovs, ovs-dpdk, collectd, kubelet, OVN north/south controllers and many more, that are required to be part of the Edge stack, also need to be containerized and have helm charts. Where do we do them? As Akraino or as a sister project?
My thinking is that to make Akraino complete integration project, it would need to have capabilities to build the images.
Thoughts?

The current code is only the seed code that AT&T generously donated to kick-start the project. Obviously there are pieces missing and maybe pieces we may not need / want to do differently later. I wouldn't extrapolate from the seed code to the project's mission/focus that the community needs to agree on.
Then, notice the code is integration code. It pulls in pieces from Airship and other upstreams (which themselves are development projects).
Ok, if you're not talking about patches for backporting but to fix/add functionality this would be forking and I hope we'll establish a clear upstream-first policy to prevent forking. Apart from that it would not be good citizenship to not upstream / not give upstream the chance to address gaps first, we'd accumulate technical debt that we don't want. I often hear the argument that these patches are "temporary" to enable us to move fast and that there's the intention to eventually upstream... which from experience hardly ever happens later.
It's a different, of course, if we're talking about plugins like in your Barometer example.
Could you maybe elaborate why you feel it matters whether building images is part of the project or not?
In my view, we should eventually build images to make internal testing and test-driving by users easier. But I'd like to avoid the trap of putting too much emphasis on the images; how they are built, how to harden them, how to tune/optimize them, etc. Just mentioning this, as it's a topic that typically comes up sooner or later (like recently in ONAP). And it's important to understand that users will likely throw away our images and rebuild & re-test anyway.
I'd expect that we'll identify gaps as a result of the integration. If it's a gap in an upstream project, we should absolutely strive to address those gaps there and never carry patches against an upstream project. If it's a functional gap not addressed by our current upstreams, we should try to find projects that do something similar and see whether we can extend those. Developing ourselves should be last resort and then as an independent (sub-)project that will need to prove its value to the larger community over time. Plus it should be possible to swap it out for other solutions if they develop elsewhere.
Whatever code we produce ourselves should of course strive towards production quality. But it's not our task to create patches to fix upstream projects or even do backports to an upstream's stable branch! That's the job of the upstream projects themselves.
And because everyone, both upstreams and us, has finite engineering resources, they have to trade off how much time they spend on backports to older, stable branches vs how much time they invest into new features. Plus how many HW/SW configurations they are able to fully test.
Now consider an edge stack that consists of dozens of components. It's already difficult to find combinations of versions of components that play well together, let alone the complexity of doing backports across all of them.
Next, consider how users would consume Akraino: Would they just download our/upstream images and run them in production? Of course not! They'd have to get commercial support from vendors (unless they have many engineers to burn to go DIY), but vendors will in most cases not support the exact combination as integrated/tested in Akraino, so the effort we put in there has a relatively low ROI...
TBH, this all makes the goal of "production quality" for the whole Akraino stack rather aspirational than realistic...
