Announcements

Agenda

• Discuss October bug bash results
• KubeCon plans (sessions, booth, etc.)
• Emeritus maintainer section?

Discussion

• This issue https://github.com/project-akri/akri/issues/706. Added finalizers to make sure we don't miss delete events. Avoiding continuing to watch for devices
  • Workaround:
  • better documentation
  • update agent to handle termination request by first removing finalizers
  • Helm post-delete hook - but unlikely that that is something we'd want
  • consensus: document it and ideally add the hook
• Controller no longer responding to updated instances … Agent updated to not delete instances on config changes but controller still only reacts to new instances
  • add to release notes and create issue to track
  • Controller needs to watch Configuration changes for the broker image
  • The Agent only does what it should now in preparation for the Discovery and Deploy Config split. The Controller ideally would just watch the Deploy Config.
• Do we still want to release?
  • We have a lot of improvements! Such as no longer using the containerd socket
  • I believe that there will be interest in the release but we need to be clear about the regressions
  • One workaround if you want the controller to work, when you want to update your config, delete it first and then apply the updated one
  • Release? Kate, yes. Yu Jin, yes. Nicolas, yes. Shekar, yes.
• Should we no longer install the controller by default?
  • It tracks agents/nodes going down but that could be considered an edge case
• We can always create a minor release of Akri with a bump in the helm chart. Let's create less work for ourselves
• Akri blog: https://medium.com/akri
• KubeCon plans (sessions, booth, etc.)
  • Talk with demo focused on MQTT. Blog with demo https://www.fermyon.com/blog/mqtt_trigger_spinkube
  • Akri booth on Thurday
• Emeritus maintainers
  • https://github.com/helm/helm/blob/main/OWNERS
  • Need to figure out if the structure of that OWNERS file is respected by GitHub
  • Update Governance document with criteria for moving someone to emeritus https://github.com/project-akri/akri/blob/main/GOVERNANCE.md
  • If a maintainer is in the CNCF books, they also need to be removed from all of that
  • Kate and Nicolas will want to be moved to emeritus for a year or so.
  • Can always be moved back to an active maintainer
  • Yu Jin plans to still maintain OSS engagement. Microsoft is planning to pour a lot of investments into the project in February
  • Do we still want to have monthly meetings before this?
  • Will still have the December meeting

Action items

• Kate fix e2e tests
• Nicolas update docs for controller
• Kate look at adding Helm hook
• Yu Jin create release Friday (release notes will be the delineation of improvements) Can give feedback in PR to update https://github.com/project-akri/akri/blob/main/CHANGELOG.md
• Yu Jin update Governance document
• [AFTER KUBECON] Kate looks at handling updating CODEOWNERS with emeritus

Discussion

• Kube on Edge Day Talk: MQTT trigger upstreamed to SpinKube!
  • Akri automatically puts prefix on device properties
  • if you put env var on SpinKube, they will be put as application var
  • hopefully won't need to upstream anything else to do an e2e MQTT + WASM demo
  • demo is a fake device – we need to come up with an exciting use case/scenario
  • we can pull something together with SUSE distro as well
  • Andrew also had a talk on Kube on Edge Day accepted!
    • kiosks - will mention Akri for discovery path
• Controller refactor work
  • want to get kubers up to latest - has a lot more since we started using it while back with new features/docs/etc
  • getting controller up to date
  • need to rewrite the tests
  • bump all our other dependencies then cut a release
  • when we bump, we should try to get rid of the h2 patch
  • check kubernetes using correct go client
  • how long do we want to support different versions of Kubernetes?
    • support as long as Kubernetes officially supports them
    • if Kubernetes phases out / deprecates a version, we should do the same
    • each release supported approx. a year
    • https://kubernetes.io/releases/
    • bug bash - test on last three latest
    • need to update version in the test matrix (v1.16 or higher)
• bug bash scenarios to cover agent + controller refactor
  • reclaiming of slots (when workload deleted, slot gets reclaimed)
  • multiple nodes scenario discovering a device (debug echo, ONVIF, etc. keep it generic)
  • kubeRS client - mess around with CRs: update configurations, delete/apply, see how agent + controller handle state changes
  • kick off bug bash in the next community meeting
• monthly metrics
  • no new issues
  • more new downloads for the newer versions
  • few more video views
  • why are there more controller downloads than the agent in 0.12.9?
    • probably from someone's CI

  • Spin has MQTT trigger so we discover MQTT topic with Akri and deploy Spin serverless app
  • shows real edge scenario that dynamically run when devices are updating / sending new info
  • can't do anomaly detection, instead something like message forwarding or aggregation (each time sensor sends to topic, forward the data)
• Removed stale bot

Agenda

• Submitting Kubernetes on Edge Day submission for the above
  • past four Kube on Edge Days have had a talk on Wasm, so this would be a good session
  • had to make a few changes to repo to make demo work
  • changes to shim
• Agent refactor PR has been approved! Thank you Nicolas for all the work on it! Comes with support for CDI and security benefits of no more crictl slot reconciliation
  • the improved security posture will help us get to v1.0 Akri!
  • Use project board to track progress to Akri v1.0? https://github.com/orgs/project-akri/projects/2
  • go back to moving DH/samples out of main repo which would help progress
  • we should set up async bug bash and get a release out soon
    • need to create scenarios to test, talk to nicolas about where there may be edge cases
    • Simulate a scenario where we need to do slot conciliation
    • Does it support multiple DH of the same protocol and properly aggregate the devices
    • what happens if one DH goes down?
    • August release?

Announcements

• Akri Maintainer @johnsonshih announced his retirement. Congrats Johnson!

Agenda

• Metrics readout
• Review proposals for KubeCon NA

Discussion

• Metrics readout from Ethan

  • Slightly less GitHub clones
  • No new issues opened or closed
  • Key videos have some views
  • Constant number of slack channel members
  • People are using the latest version. Some are still using 0.12.9 which is the last version where we still use the architecture tag in the image name
  • 168 people visited the repository over the past 2 weeks

• Review proposals from KubeCon NA

  • Azure Mec App accellerator: mec-app-solution-accelerator. For writing solution for apps on private networks. Uses K3s, Dapr, MQTT, etc

    • KubeCon conference edge track is called "Connectivity TRack", so thinking that may have a better chance of getting into the conference if combined concept of networking with the edge
    • Potentially get customer to participate as a case study

  • Akri + SpinKube

    • WASI NN - Want to do something AI related
    • MQTT trigger in spinkube
    • USB microphone detected by Akri and use speech to text with Spin LLM
    • Kate and Yu Jin with Joe in support

  • Resubmit CFP from KC Paris? DRA work has moved in a different direction so it would be a lot of work to catch up

  • Case Study may be submitted from SUSE

• Stale issues

  • A lot of issues that go into the stale state. Should we extend that period? Decision: remove stale bot

• Security issue: Akri container is mapping containerd.sock to the host for slot reconcilation

  • https://github.com/project-akri/akri/issues/682
  • Get rid of reconciler by going to DRA or change the way we do reconciliation in Agent refactor PR. Now slot reconciliation asks the kubelet what the current resource usage of the node is and reconciles the instances. There may be a race case on time between containerd and kubelet (kubelet may remove the resource before the container gets killed). Worst case, developer tagged release that developers test
  • Aim to get agent refactor in by end of the month

• Usage survey for Akri (https://discuss.kubernetes.io/t/cncf-project-akri-usage-survey-and-latest-update/28083)

Discussion

• Talk ideas for KubeCon NA

  • we should aim for main conference talk instead of Kube on Edge day talk
  • something with WASM orchestration? AI?
  • should get feedback on CFP from community and Ralph
  • could do another Microsoft Booth theater session and Akri Project Pavillion booth
  • CFP due June 9
  • use the next community meeting time to review and submit CFPs

• Timeline for Akri v1.0?

  • still in discussions about how DRA will
  • refactor agent, split config we should do before DRA but maybe we should postpone DRA for 1.0
  • written guide on how to deal with discovery handlers
  • split repositories
  • security items need to be addressed
  • look at how we version akri
  • if we have v1.0 by december/january, would make good content for main conference talk at next kubecon about lessons learned on going to v1.0
  • we can also announce with submission to CNCF incubating project
  • have features in by november could be a stretch goal due to the on-going refactory
  • split config proposal is good to go as soon as agent refactor is complete
  • wait for the agent refactory, then work on the controller
  • try to work on these in parallel if we can
  • improve e2e test coverage - when testing refactor of agent, there were corner cases that weren't covered
  • change DH interface - instead of streamed connection, have a strictly pull or push connection
    • maybe we can table this for v1.1
    • we can give the option for users to choose especially in disconnected scenarios where latency might not matter as much for offline devices
    • shared attribute per device
    • v1.0 we should focus on getting stabilized user API

• usage survey

  • created a short survey which included basic questions about akri
  • most important information we want to get is what kind of device are they discovering with akri
  • are there any specific feature requests
  • made a simple post on twitter/slack, microsoft tech community blog, ecosystem discussion board for kubernetes, etc.
  • are there other places we can post the survey?
  • we'll keep the survey up for 1-2 months
  • so far we don't have any responses

Announcements

• Akri v0.12.20 is live!

Agenda

• KubeCon EU 2024
  • Yu Jin and Nicolas had a talk at Kubernetes on EDGE Day
  • Talk went well and demo worked (after a small network hiccup)
  • 100+ people
  • Good feedback after the talk – talking about it at the booth
  • SUSE gave keynote at Kubernetes on EDGE and talked about the tiny edge and Akri's role
  • Akri booth: originally on wait list and got off it for Thursday evening. Fun to have the dynamic demo
  • Used Akri twitter to promote. Not a great booth spot for visibility
  • Nicolas, Yu Jin, and Reese had joint session at Microsoft booth. 3 options: open source, SUSE edge 3.0, or Azure IoT operations
  • Nicolas: a little disappointed in that people didn't want to try to print something after seeing the demo
  • Nicolas had a discussion with DRA maintainers (Patrick and Alexander). They are moving it in the wrong direction. Nicolas is trying to get more involved. They are more focused on the autoscaler, and want to integrate the device as being a part of the node. They are focused on the GPU story. They are linking the device to the node with a resource that looks like the Akri Instance CRD but with one node rather than a list. Capacity is also an issue: 1 or infinity. Nvidia is also interested in network based devices. Without tying resources to nodes, it adds latency and complexity to the scheduler. And AI workloads may want to filter more on a specific GPU. Currently have NameResources which has a list of devices for a node. Idea is that the scheduler doesn't have to ask anyone to schedule a job. After some conversation, Patrick said maybe we could change the node field to be a node selector. DRA maintainers asked if they could reference our Rust DRA implementation.
  • Kate: All this being said, are we going to merge or keep working on all the DRA changes?
    • Nicolas: lets finish all the refactoring work: finishing agent refactor, splitting up CRDs, arbitrary resource creation, splitting out repository
    • Nicolas: But overall think we will continue eventually use DRA
  • Yu Jin: After the Microsoft booth session, people asked how Akri is different from KubeEdge. They have protocol mappers from edge devices for a variety of protocols. Not sure if their device bridging operator is independent and could be applied to other clusters
• Community engagements (metrics and ideas)
  • Ethan has been looking at our release metrics and has some ideas on how we could improve our visibility
  • Generates ecosystem visibility reports every month
    • issue board visits
    • unique clones
    • unique repo visitors
    • visit numbers of Akri home site
      • do we have google analytics numbers?
      • or would porting to netlify give us those numbers
    • YouTube video views
    • Unique downloads
      • agent or controller? - would be ideal to track both
      • do we need to be wary about whether these are used in workflows?
  • Do we want to record maintainer contributions?
    • devstats through CNCF does this: https://akri.devstats.cncf.io/d/8/dashboards?orgId=1
  • Want to update some of the demo links to the site. How to do that?
    • Add PR to https://github.com/project-akri/akri-docs
  • Issues
    • Many are created by the maintainers. Can we create a label to track the ones that are not created by maintainers (say "ecosystem")?
    • Kate: is this something you see in other projects?
    • Ethan: Akri seems unique in that it has a lot of issues created by maintainers
    • Kate: I have seen this pattern in other projects such as Spin and SpinKube. It is a great way with maintainers to keep track of todos.
    • Ethan: Looking for a way to make sure we are tracking user issues
    • Nicolas: we have the bug label that specifies something as needing to be fixed vs enhancement which is lower priority.
    • Kate: Response to issues also needs to be improved - probably would be resolved by recruiting more active contributors

• Cut release soon? Status of DRA?

Discussion

• Bug with deallocating resources with DRA mode
  • kubelet is crashing
  • has started talking to the DRA folks about it
• Cutting a release?
  • agent refactor could maybe go in soon
  • it would be worth cutting a release to add this (adds CRI) but we would not have a feature set
  • should cut a release before KubeCon since we have things like updates of dependencies
  • RUST security issues came up – we should make sure these are not affecting us and resolved
  • update dependendabot
  • DRA: don't think we can land DRA anytime soon, but all the things related to refactoring agent and controller / splitting config / refining API can be done without DRA being active
  • may be able to merge DRA later to continue testing but DRA should not be default yet
  • version matrix of which versions of akri support which version of kubernetes
  • we should aim to cut the release by Thursday the 14th
  • in that time if someone can update dependendabot that would be great, but otherwise we already have other dependency updates in
  • We use actix, tonic (axiom), and a third web server. Let's choose one. Also, can use kube rs crate for our webhook. https://github.com/project-akri/akri/issues/375
    • Lior to try and tackle this before cutting release
    • example: https://github.com/kube-rs/kube/blob/main/examples/admission_controller.rs#L24
• in case of cert rotation, what is a common approach to address this (currently webhook reads a cert once and uses it forever)?
  • is there a way to automate if secret is rotated, pod restarts?
  • potential approach: whenever request comes in from server, webhook always reads current cert from storage if it is a volume mount
  • if kube-rs has utils for cert rotation we should investigate
  • Johnson to open an issue on supporting cert rotations
• how do we grow community and maintainership?
  • Community growth
    • flashier demos (AI)
    • more conferences (Scale)
    • CNCF Webinars
    • Collaborate with other CNCF projects
    • List who is adopting Akri
    • akri gathering for a weekend to meet deadlines and have a hackathon day together
    • Get us listed on Kube RS adoption: https://kube.rs/adopters/
    • Get us listed under device plugin interface
    • (later) get us listed under DRA
    • https://github.com/project-akri/akri/issues/688
  • Maintainership
    • KPIs - X bugs a season
    • Once we get to 1.0, we will have more things like performance testing. If more stable, then more people interested in maintaining
    • triage rotation - i.e. one person tackles responding to issues for a week then rotate?
      • Kate to maybe help set up spin app for triage rotation
      • folks should be able to mark times off
      • promote/remind in Akri Slack good first issues so community can take them on
• Should we switch to using OTEL
  • Kate: switch to OTEL since a lot of other people/projects use OTEL
  • Johnson to create an issue to track this
  • could be a good community member ask since there are other experts out there on telemetry
• moving DH out a repo
  • udev is moved out and could potentially move the rest out but need to resolve versioning
  • this would make it easier for others to contribute to akri
  • close to supporting Windows (update socket usage?) for Akri

Action items

  • once a week has been a good cadence (Lior)
  • if there are many pending PRs we can have a more frequency review, but PR owner would need to be present
  • feedback received in the sessions were good (Nicolas)
  • would be great to have these merged before kubecon
  • might not be realistic to cut a v1.0 release by kubecon at this point
    • may have all the features we want in API 1.0 as PRs (maybe not all merged
    • security review, benchmark testing, etc. need to be done before v1.0 is cut

  • not needed: status for resources
  • not needed: arbitrary scheduling of resources
  • nice to have: discovery handlers pulled out, but we can take a deeper look at release/build pipelines and discuss
    • besides the agent refactor work, our work should not be affected by the reorganizing of the discovery handler into separate repo
  • weekly/biweekly cadence to review things?

    • from there move to biweekly if necessary
    • before we meet, let's establish in slack what we want to cover in the meeting
    • first, we can discuss refactor of agent
• WASM discovery handlers
  • we should still look into this at some point
• Issue triage / open PRs
  • close autoupdate dependencies PR to see if bot will kick off a new one
  • update tonic and prost: opc ua has created a new release, so this should be ready to update and merge
  • refactor agent: we should review and cover in next weekly review meeting
  • update docs PRs with labels
  • akri DH unable to detect IP camera: no response so we can close
  • lorawan support: move to backlog
    • need to investigate the licensing for lorawan and whether it is permissible within CNCF
  • add instructions for akri instance ownerreference when requesting akri resources: doesn't interfere with controller's owner refs
  • pods with unready containers exist on node, can't clean slots yet - investigating
  • containerd.socket security concern / best practice: check agent refactor work - investigating new approach
  • agent-registration.sock and udev.sock socket files world readable - investigating
• next weekly review meeting
  • we can do ad hoc at first but we should have summary / key takewaways from review meeting
  • in the future we can take notes or record if necessary

Action items

• Ad hoc code review of agent refactor meeting on Tues, Jan 16th 8-9AM PT

Agenda

• Migrating discovery handlers and samples out of main repo
  • PR to move udev DH
• Review proposals?
• Issue triage

Discussion

• Akri in Azure IoT Operations Public Preview
  • OPC UA is private discovery handler
  • planning on leaning on community and partners for more discovery handlers
• PR to move udev DH
  • pending, hoping to get back into this soon
  • ordering of moving DH? do we want to prioritize which ones move out in what order
  • debug echo will stay for debugging
  • allow agent to be able to pull WASM discovery handlers
    • what does WASI support? async might be difficult
    • for now pull them out and keep embedding as crates
    • reverse compatibility?
    • need to be particular about interface/runtime we choose to support
    • WASI over WASIX and work with Bytecode Alliance to get a fuller feature set
    • containerd shim will also define runtime we use (if we want DH to be pod)
    • could also do embedded binaries (should we offer the option?)
    • if user doesn't have containerd shim, use same deployment manifest to add runtime class and change (with helm chart)
• Proposals
  • we should add proposals tag in the PR
  • external device inventory: Johnson's picking this up, will ask him to update the PR with any changes he is making to Leo's initial proposal
  • arbitrary broker resource type: changes API (splitting resources)
  • status field: also waiting for resource splitting
  • MQTT DH: will wait for current DH to be out of main repo
    • currently Nicolas has reference implementation
    • if we accept as is, we can move the repo to Akri
  • DRA mode: first need to split config
    • this one's likely the first to be implemented
    • maybe we can make split config proposal
    • need to decide on naming (likely discovery configuration)
    • first split config, get merged then get DRA one merged
• Setting goals for getting Akri to Incubating project
  • great idea, we should finish all the changes we started and get to stable API state then apply for Incubating
  • opportunity to bring in lots of contributors but right now there are so many changes that it is difficult for new users to touch code
  • we can start thinking about goals soon
• Issue triage
  • #659: ask if Johnson's comment resolved issue, if so we can close
  • #662: controller pod restarts under normal conditions
    • wanted to bubble up errors into restarts
    • could consider not bubbling up errors if this is bad practice
    • had this request previously from IIoT team
    • new kube controller with API changes will hide all the restart errors - can close on this issue
  • #674: good first issue to point new contributors to
    • moving away from tarpaulin in favor of rust-based coverage tools
    • add to backlog
  • #677: lorawan support
    • once we move all DH into their repos, this will be up to someone to build
    • maybe they have one that's not OSS that they want to use
    • need to add docs where all the DH and images live and instructions on how to add them to helm chart
    • we probably don't want to add support for any DH that we cannot test
    • clarify whether they are asking for or asking to provide it? how can we support them?
  • Docs #35: goes along with requesting instances page and adding owner reference (good first issue)
    • would this not mess with the controller?
    • need to find a way to ensure they don't overlap
    • should try it before documenting
  • Docs #83: something in gitbook configuration
    • someone with admin rights on gitbook should have to change them
  • Docs #84: good first issue
  • Docs #103: we can fix and redirect
    • can we do this or need to put in CNCF ticket?
  • #678: will likely be a breaking change on OPC UA DH
    • good first issue
    • would be good to get someone else's eyes on it with more expertise on OPC UA
  • #681: this may be expected behavior but not desired behavior
    • slot reconciliation is not something we're planning to change with DRA
    • should look into better ways of claiming the slots
    • need some clarification - output doesn't make things clear
