They are not the only +contributor(s) to this work, and not necessary doing most of the coding! +They are expected to be available on IRC and the ML for questions, and report +status on the whiteboard_ for the weekly IRC sync-up. The number of primary +contacts is typically limited to 2-3 individuals to simplify communication. +We expect at least one of them to have core privileges to simplify getting +changes in. + +.. _whiteboard: https://etherpad.openstack.org/p/IronicWhiteBoard + +Priorities +~~~~~~~~~~ + ++---------------------------------------+-------------------------------------+ +| Priority | Primary Contacts | ++=======================================+=====================================+ +| `Deploy Steps`_ | rloo, mgoddard | ++---------------------------------------+-------------------------------------+ +| `BIOS config framework`_ | zshi, yolanda, moddard, hshiina | ++---------------------------------------+-------------------------------------+ +| `Conductor Location Awareness`_ | jroll | ++---------------------------------------+-------------------------------------+ +| `Reference architecture guide`_ | dtantsur, jroll | ++---------------------------------------+-------------------------------------+ +| `Graphical console`_ | mkrai, anup-d-navare, TheJulia | ++---------------------------------------+-------------------------------------+ +| `Neutron Event Processing`_ | vdrok | ++---------------------------------------+-------------------------------------+ + +Goals +~~~~~ + ++---------------------------------------+-------------------------------------+ +| Goal | Primary Contacts | ++=======================================+=====================================+ +| `Updating nova virt to use REST API`_ | TheJulia | ++---------------------------------------+-------------------------------------+ +| `Storyboard migration`_ | TheJulia, dtantsur | ++---------------------------------------+-------------------------------------+ +| `Management interface refactoring`_ | etingof, dtantsur | ++---------------------------------------+-------------------------------------+ +| `Getting clean steps`_ | rloo, TheJulia | ++---------------------------------------+-------------------------------------+ +| `Project vision`_ | jroll, TheJulia | ++---------------------------------------+-------------------------------------+ +| `SIGHUP Support`_ | rloo | ++---------------------------------------+-------------------------------------+ + +Stretch Goals +~~~~~~~~~~~~~ + +.. note:: Upon completion of `Storyboard migration`_, the stretch goals + documented here will be migrated to and tracked in Storyboard. + ++---------------------------------------+-------------------------------------+ +| Stretch Goals | Primary Contacts | ++=======================================+=====================================+ +| `Classic driver removal`_ | dtantsur | ++---------------------------------------+-------------------------------------+ +| `Redfish OOB inspection`_ | etingof, deray, stendulker | ++---------------------------------------+-------------------------------------+ +| `Zuul v3 playbook refactoring`_ | sambetts, pas-ha | ++---------------------------------------+-------------------------------------+ + +Details +~~~~~~~ + +Deploy Steps +------------ + +We created cleaning with the the ability to compose an ordered list of +actions to be taken. However we left deployment as a static set of actions. + +In order to allow templates to apply using chosen traits, we want to have +the same functionality and framework that we obtained with cleaning to apply +to the deployment of a node. + +This will start with the goal of splitting apart the action of writing the +image during the deployment from the act of writing the configuration drive +into two distinct steps. From there, we will further iterate. + +This may ultimately facilitate de-duplication of deployment logic which +was an uncompleted goal from the Queens development cycle. + +BIOS config framework +--------------------- + +Some drivers support setting BIOS (UEFI, etc) configuration out-of-band. We +would like to introduce a framework (HTTP and driver API) for drivers to +expose this feature to users. + +Conductor location awareness +---------------------------- + +Often operators have made changes to driver names to facilitate mapping of +conductors to individual nodes, such that conductors are local to nodes, +and a conductor in Los Angeles is not trying to control machines in Europe. + +This allows ironic to remain a single pane of glass, and provides increased +flexibility in deployments of ironic. For now, we will focus on hard +affinity with an upgrade path. + +Reference architecture guide +---------------------------- + +To help new deployers make the right choices, we need a document describing a +reference architecture for an ironic deployment, especially around +multi-tenant networking and co-existing with VMs. + +Graphical console +----------------- + +We need a way to expose graphical (e.g. VNC) consoles to users from drivers +that support it. Specifications and patches are in various states, and +need to be picked up again. We are hoping to have the initial framework +to support graphical console usage in this cycle. + +Neutron event processing +------------------------ + +Currently ironic has no way to determine when certain asynchronous events +actually finish in neutron, and with what result. Nova, on the contrary, uses +a special neutron driver, which filters out notifications and posts some of +them to a special nova API endpoint. We should do the same. + +Updating nova virt to use REST API +---------------------------------- + +Cycle after cycle we encounter issues with the upgrade sequence and the API +version pin that we increment in the Nova virt driver that supports ironic. + +It is time to put this to an end and better properly support versioned +interactions with our API. Upon discussing with the Nova community, +we reached consensus that it is time to transition our API calls to +direct REST calls as opposed to calls through the python-ironicclient library. + +Storyboard migration +-------------------- + +Ironic has planned work in many different ways over the years, and we have +learned that there are positives to each approach. + +As our team has also become smaller, we must also enable better focus by +integrating distinct tools, systems, and processes together. + +With Storyboard, we will gain the advantage of planning and tracking work +in a single system. + +Management interface refactoring +-------------------------------- + +As time has gone on, we have found the need to have a single place to +control the boot mode for nodes. This effort is refactoring the +management interface so we move distinct boot mode related +actions into a single interface. + +Getting clean steps +------------------- + +One of the biggest frustrations that people have with our cleaning model +is the lack of visibility into what they can do. We have ideas on this +and we need to begin providing the mechanisms to raise that visibility. + +Project vision +-------------- + +We all have different ideas of where we would like to see ironic in +two, five, and ten years. Discussing this as a group helped us scope and +frame our discussions so we were on the same page. + +We should write down our collective vision of the future, and see where it +takes us. + +SIGHUP support +-------------- + +SIGHUP is the signaling mechanism to indicate that a program should attempt to +reload configuration and possibly restart itself. Supporting SIGHUP_ is an +OpenStack project wide goal, and it should be easy for us. Let's do it! + +.. _SIGHUP: https://governance.openstack.org/tc/goals/rocky/enable-mutable-configuration.html + +Classic driver removal +---------------------- + +We have deprecated the classic drivers, and soon is approaching the time to +remove these drivers now that we have provided a means to migrate users to +hardware types. Deprecation took place on Feb 1, 2018, and thus this code can +be removed after May 1, 2018. + +Redfish OOB inspection +---------------------- + +Redfish is one of our in-tree "reference" hardware types, however we have no +support for out-of-band inspection. In terms of providing feature parity, +we should move forward with this, as more vendors are moving to Redfish. + +Zuul v3 playbook refactoring +---------------------------- + +One of the powerful features with Zuul v3 is that we execute ansible playbooks +as opposed to traditional shell scripting. The migration left quite a bit of +legacy shell scripts in the testing process. + +Efforts are underway to remove the bulk of this launch scripting from our +normal devstack jobs. We should expect our grenade jobs to remain untouched.
