📝 WalkthroughSummary by CodeRabbit
WalkthroughThe NeutronAPI resource now supports WSGI deployments with dedicated RPC and worker Deployments. It reports their readiness through status fields and conditions. Templates, database synchronization, reconciliation, and functional tests now support the WSGI strategy. ChangesWSGI Neutron deployment
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: ⚪ Minimal · up to The change adds an opt-in WSGI deployment path while preserving legacy behavior when the annotation is absent. The remaining concerns are limited to localized test maintenance, so no actionable merge-blocking risk remains after normal checks and review.

1505-1525: 🚀 Performance & Scalability | 🔵 Trivial | ⚡ Quick winAvoid an unconditional Delete on every legacy reconcile.
The annotation is absent by default, so this branch runs for most instances. It issues two Deployment
DELETErequests on each reconcile, which produces constant NotFound traffic and audit noise. Gate the cleanup on observable state, for example only wheninstance.Status.RPCReadyCount != 0,instance.Status.WorkerReadyCount != 0, or the corresponding condition is still present.Also log the deletion with
Log.Infoand structured keys so the strategy switch is traceable.🤖 Prompt for AI Agents

while scanning customServiceConfig, and only parse rpc_workers when the active
section is [DEFAULT]. Preserve the existing handling for blank lines, comments,
invalid values, and the not-found return.

- Around line 1436-1449: Initialize NeutronRPCReadyCondition and
NeutronWorkerReadyCondition to Unknown or False immediately after
Conditions.Init() and before the child Deployment generation checks in the
reconciliation flow. Ensure both conditions remain non-true until their
respective Deployments have matching Generation and ObservedGeneration, while
preserving the existing readiness updates in the rpcDeploy and worker deployment
branches.

OpenStack Master removes Eventlet from neutron-server, requiring the API to run under httpd/mod_wsgi and RPC/background work to move to their own processes. Introduce this as an opt-in strategy, gated by the neutron.openstack.org/wsgi annotation defaulting to the legacy Eventlet strategy when absent so upgrading the operator alone never changes an existing deployment's behavior. When wsgi=true: - the "neutron" Deployment runs a single httpd/mod_wsgi container instead of the eventlet neutron-api + httpd reverse-proxy pair - a new "neutron-rpc" Deployment runs neutron-rpc-server, and is skipped entirely when rpc_workers=0 is set in customServiceConfig - a new "neutron-worker" Deployment runs neutron-periodic-workers and, when OVN is enabled, neutron-ovn-maintenance-worker Adds neutron_wsgi and neutron_rpc_disable kuttl suites covering a fresh WSGI deployment and the rpc_workers=0 disable path.
