Revision as of 22:49, 10 September 2014 by Rm you (talk | contribs)

This page tracks Neutron Loadbalancer as a Service (LBaaS) meeting information. The OpenStack Networking Team (Neutron) holds public meetings in #openstack-meeting on Thursday at 1400 UTC. Everyone is encouraged to attend.

Meeting 11.09.2014


  • Obligatory incubator update?
  • Barbican integration -- Keystone Trusts, comments and concerns (rm_work)

Meeting 21.08.2014


Meeting 14.08.2014


  • Review the work items from the Hackathon and check on the status and/or if we still think it’s relevant
  • stats of pool in v1 is moved to loadbalancer in v2. Better to have it in listener or leave it in pool.
  • New common Barbican utilities module - how do we proceed

Meeting 6.08.2014


  • Review Updates
    • Review politicking (How likely is v2 to actually get merged in?)
  • Separating deployment and operational status.
    • Operational Statuses - ACTIVE, INACTIVE
  • Calling driver interface on every API request (i.e. create pool before create lb)
    • Support for multiple providers is what doesn't allow this currently
    • Only solution would be for all entities to be individually tied to a provider
  • Octavia update

Meeting 31.07.2014


  • Review Updates
  • Octavia Work
  • Parallel TLS Work
  • Change to move handling of ACTIVE/ERROR/DEFERRED and db deletes out of drivers
  • Don't let gerrit overwrite dependent commits
  • LBaaS related talk submissions
  • Design sessions.
    • Do we want to prepare for 3? One on Octavia, one on Flavor framework (with Advanced Services team), and on one Neutron LBaaS.
    • When are the deadlines for design sessions so we don’t miss it.
    • Also should we talk at the next summit about prioritization of the K work? Should we have some specs/BP submitted prior to the Paris summit?
  • Mid-cycle meetup.
    • I have noticed that Neutron has their mid-cycle meetup right before juno-2 and nova had it this week. What is the best time for us to have our next meetup? Before kilo-2 or right after?

Meeting 24.07.2014


  • Review Updates
  • TLS Work Division

Meeting 17.07.2014


  • Review Updates
  • Discuss blockers and how to mitigate
    • Juno release coming quickly!

Meeting 10.07.2014


  • Paris summit talks (Susanne)
  • Code review issues
  • Shim vs. Agent Refactor

Meeting 03.07.2014


  • Are shim layers really needed for Juno?
    • If the old API and new API will coexist independently, why is a shim layer needed?
      • Has the caveat that the pools resource can exist independently in both APIs.  This can be accomplished by renaming new API pools to something different or by doing a shim for the pool resource.
  • Should the agent refactoring be included in the main object object model refactor?  The plugin might be able to just call the namespace driver directly, with some modification.
  • Status of entities that only exist in the database and not in a backend (i.e. they are not linked to an existing load balancer)
  • Can the existing drivers continue to be enhanced in Juno release?
  • When will the "core" code land in gerrit?

Meeting 26.06.2014


  • Updates
  • Node pools vs pools naming.
    • Moving discussion to ML
  • Mark McClain's flavor blueprint
    • Everyone please review. Meeting tomorrow on this item.
  • TLS blueprint update (evgenyf)
    • We agreed to move dev effort to v2 only.
  • L7 switching blueprint (avishavb)
    • Everyone please review bp.

Meeting 12.06.2014


Meeting 05.06.2014


  • Hackathon logistics
    • Plan for hackathon in 2 weeks
    • Possible scope of hackathon
      • API Revision in Neutron LBaaS
        • By the time the Juno freeze occurs what functionality will be exposed via the Neutron LBaaS API (SSL? L7? etc.)
      • Cleaning up Neutron LBaaS plugin interface points
      • Getting reference implementation up to date with API revision
    • Choose direction for barbican integration
      • Using eventing model
      • Pushing orchestration decisions to GUI & power API users
  • BP refactor review

Meeting 29.05.2014


  • Finalize first object model refactor blueprint
    • https://review.openstack.org/#/c/89903/
    • N:M vs 1:M LoadBalancer to Listener relationship
      • IPv4 and IPv6 addresses on LoadBalancer
    • N:M vs 1:M Pool to HealthMonitor relationship
      • Should deprecation be left to another blueprint?
    • M:1 vs 1:1 Listener to Pool
    • Pool status
  • Epic/Umbrella blueprint for tasks needed complete object model and API refactor

Meeting 22.05.2014


We should also discuss that the new API is going to require a different workflow to get a load balancer up and running. How is this going to look and if it makes sense. I think the creation workflow would be this:

  • Create Pool
  • Create Pool Member(s) and associate to Pool
  • Create Listener and add pool to this listener.
  • Create Load Balancer and add listener to this load balancer.

This might have some issues as I think there might be an expectation that the root object should be created first. In this case the load balancer is the root object and is created last. So Another option is:

* Create Load Balancer
* Create Listener and associate it with the load balancer
* Create Pool and associate with Listener
* Create pool member and associate with pool

Problem with this is when does the actual load balancer process get spun up? And does this solve for the M:N relationship between load balancers and listeners? A load balancer should be able to add an existing listener.

  • Should subnet_id live on the pool, pool members, or somewhere else?
  • Driver abstract class changes needed to support new API

Current methods are:

  • create_vip, update_vip, delete_vip
  • create_pool, update_pool, delete_pool
  • create_member, update_member, delete_member
  • create_pool_health_monitor, update_pool_health_monitor,
  • delete_pool_health_monitor
  • stats

We may only need to change vip to loadbalancer and thats it.

Meeting 01.05.2014


Meeting 10.04.2014


  • Networking functions vs Virtualized appliances

- need to discuss basic concepts beyond lbaas API. Particular objects only vs the notion of Loadbalancer.

  • Update on API discussion
  • Status fields: admin, operational, deployment

- member status

Action Items

  • Jorge to engage in "Single API" discussion on ML
  • outline issues of existing LBaaS API
  • Jorge to create API proposal based off of Atlas API spec.
  • Add "least common denominator" requirements to wiki

Blueprint Tracking

  • Loadbalancer instance

We'll revisit the rationale and the design of the feature.

  • L7 rules

Discussion Topics

  • Downstream version of lbaas (?)
  • Service Type Framework (providers)

We have a patch on review https://review.openstack.org/#/c/64139/ that introduces the ability to configure different providers with the same vendor driver and different configuration parameters. That looks like something that is better addressed with flavors.

Open discussion

any other topics you would like to bring up for discussion during the summit.
