From 5e9223a10786defc8be77ffe7d8afbffce38fbc5 Mon Sep 17 00:00:00 2001 From: Luca Miccini Date: Sat, 14 Feb 2026 15:24:40 +0100 Subject: [PATCH 1/4] Add RabbitMQ version upgrade and queue type migration support MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implements RabbitMQ version upgrade for major/minor version changes (e.g., 3.9 → 4.2) and queue type migrations (Mirrored → Quorum) using a storage wipe approach with init containers. ## Version Tracking - Status.CurrentVersion tracks the deployed RabbitMQ version - target-version annotation (set by openstack-operator) triggers upgrades - Detects existing 3.9 deployments on operator upgrade by checking for RabbitMQCluster resource existence during CurrentVersion initialization ## Multi-Phase State Machine UpgradePhase status field tracks upgrade progress and enables resumption after interruptions: - "" → "DeletingResources" → "WaitingForPods" → "WaitingForCluster" → "" Phases: - DeletingResources: Delete RabbitMQCluster and ha-all policy (once) - WaitingForPods: Wait for pod termination without re-deleting resources - WaitingForCluster: Add wipe-data init container annotation - "": Upgrade complete, clear phase when cluster ready ## Storage Wipe Implementation Data-wipe init container runs before RabbitMQ container: - Wipes /var/lib/rabbitmq (Mnesia data format changes between versions) - Version-specific marker files (.operator-wipe-{version}) prevent re-wipe - Reuses existing PVCs/PVs (no resource deletion required) - Triggered by temporary storage-wipe-needed annotation on RabbitMQCluster ## Upgrade Workflow 1. openstack-operator sets target-version annotation 2. requiresStorageWipe() checks version compatibility (major/minor changes) 3. Status.UpgradePhase → "DeletingResources": Delete cluster and policy 4. Status.UpgradePhase → "WaitingForPods": Wait for pods to terminate 5. Status.UpgradePhase → "WaitingForCluster": Add storage-wipe-needed annotation 6. CreateOrPatch creates cluster with wipe-data init container 7. Init container wipes data based on marker file check 8. Cluster becomes ready: Update Status.CurrentVersion, clear UpgradePhase 9. Next reconcile: Remove storage-wipe-needed annotation via CreateOrPatch sync ## Configuration Version Selection Uses target-version (not current version) for cluster configuration during upgrades to prevent mid-upgrade configuration changes (e.g., TLS versions). ## RabbitMQ 4.x Changes - TLS 1.3 enabled (RabbitMQ 4.x+) - default_queue_type=quorum configuration - deprecated_features.permit.classic_queue_mirroring=false - quorum_queue.property_equivalence.relaxed_checks_on_redeclaration=true - Automatic Mirrored → Quorum migration on 3.x → 4.x upgrades ## Webhook Validation - Automatically overrides Mirrored to Quorum on RabbitMQ 4.x updates - Blocks Mirrored → Quorum migration on RabbitMQ 3.x (no server enforcement) - Allows migration when concurrent version upgrade to 4.x is present - DefaultForUpdate() sets queueType=Quorum for RabbitMQ 4.x+ target versions ## Annotation Management CreateOrPatch() in rabbitmqcluster.go now syncs annotations bidirectionally: - Adds annotations from desired spec - Removes annotations not in desired spec Enables automatic cleanup of temporary storage-wipe-needed annotation. ## Init Container Preservation Checks existing RabbitMQCluster for wipe-data init container and preserves it across reconciles to avoid pod restarts. Combined with marker file check in wipe script prevents duplicate data wipes. ## Queue Type Migration Spec.QueueType change from Mirrored to Quorum triggers storage wipe workflow (same phases as version upgrades). Required because mirrored queues cannot be converted to quorum queues in-place. ## Files Modified - apis/rabbitmq/v1beta1/rabbitmq_types.go: Add CurrentVersion, UpgradePhase fields - internal/controller/rabbitmq/rabbitmq_controller.go: Multi-phase upgrade logic - internal/rabbitmq/cluster.go: Init container, wipe script, version parser - internal/rabbitmq/impl/rabbitmqcluster.go: Annotation sync in CreateOrPatch - apis/rabbitmq/v1beta1/rabbitmq_webhook.go: Auto-migration and validation - test/functional/rabbitmq_controller_test.go: Upgrade test scenarios - config/rbac/role.yaml: Remove unused PVC/PV permissions Co-Authored-By: Claude Sonnet 4.5 --- Makefile | 11 +- .../rabbitmq.openstack.org_rabbitmqs.yaml | 16 + apis/rabbitmq/v1beta1/rabbitmq_types.go | 18 + apis/rabbitmq/v1beta1/rabbitmq_webhook.go | 150 ++- .../rabbitmq.openstack.org_rabbitmqs.yaml | 16 + .../rabbitmq/rabbitmq_controller.go | 532 ++++++++++- .../rabbitmq/storage_upgrade_test.go | 317 +++++++ .../rabbitmq/transporturl_controller.go | 36 +- internal/rabbitmq/cluster.go | 137 ++- internal/rabbitmq/impl/rabbitmqcluster.go | 22 + .../rabbitmq/v1beta1/rabbitmq_webhook_test.go | 78 ++ test/functional/base_test.go | 19 +- test/functional/rabbitmq_controller_test.go | 880 ++++++++++++++++-- .../transporturl_controller_test.go | 51 + 14 files changed, 2160 insertions(+), 123 deletions(-) create mode 100644 internal/controller/rabbitmq/storage_upgrade_test.go diff --git a/Makefile b/Makefile index 77a663c5..8855094c 100644 --- a/Makefile +++ b/Makefile @@ -121,11 +121,18 @@ tidy: ## Run go mod tidy on every mod file in the repo PROCS?=$(shell expr $(shell nproc --ignore 2) / 2) PROC_CMD = --procs ${PROCS} +# Skip instanceha tests if --focus or --skip is used (focused test run) +ifeq (,$(findstring --focus,$(GINKGO_ARGS))$(findstring --skip,$(GINKGO_ARGS))) +INSTANCEHA_DEP = test-instanceha +else +INSTANCEHA_DEP = +endif + .PHONY: test -test: manifests generate gowork fmt vet envtest ginkgo test-instanceha ## Run tests. +test: manifests generate gowork fmt vet envtest ginkgo $(INSTANCEHA_DEP) ## Run tests.

The proxy transparently rewrites AMQP frames to force durability, allowing non-durable clients to work with durable quorum queues. + +## Architecture + +``` +┌─────────────────────────────────────────┐ +│ RabbitMQ Pod │ +│ │ +│ ┌───────────────────┐ │ +│ │ amqp-proxy │ Port: 5672 │ +│ │ (with TLS) │ (external) │ +│ └─────────┬─────────┘ │ +│ │ localhost:5673 │ +│ ↓ (no TLS) │ +│ ┌───────────────────┐ │ +│ │ rabbitmq │ Port: 5673 │ +│ │ │ (localhost) │ +│ └───────────────────┘ │ +└─────────────────────────────────────────┘ + ↑ Port 5672 (TLS) + │ + External clients +``` + +## How It Works + +1. **Automatic Activation**: Proxy sidecar is automatically added when: + - Upgrade is in progress (`Status.UpgradePhase != ""`) + - Migrating to quorum queues before dataplane is reconfigured + - Annotation `rabbitmq.openstack.org/enable-proxy=true` is set + +2. **TLS Handling**: + - Proxy terminates TLS on port 5672 (using certs from `Spec.TLS.SecretName`) + - RabbitMQ listens on localhost:5673 without TLS + - External clients connect to proxy with TLS + +3. **Frame Rewriting**: Proxy intercepts AMQP frames and: + - Rewrites `queue.declare(durable=False)` → `durable=True` + `x-queue-type=quorum` + - Rewrites `exchange.declare(durable=False)` → `durable=True` + - Skips reply queues and system queues + +4. **Automatic Removal**: Proxy is removed after: + - Dataplane is reconfigured with `amqp_durable_queues=true` + - User sets annotation `rabbitmq.openstack.org/clients-reconfigured=true` + +## Files Created/Modified + +### New Files +- `internal/controller/rabbitmq/proxy.go` - Proxy sidecar integration logic +- `internal/controller/rabbitmq/data/proxy.py` - AMQP proxy script (embedded) +- `internal/controller/rabbitmq/data/README.md` - Documentation for data files +- `PROXY_INTEGRATION.md` - Complete integration documentation + +### Modified Files +- `internal/controller/rabbitmq/rabbitmq_controller.go` (lines 805-835): + - Added proxy sidecar logic after `ConfigureCluster` + - Calls `ensureProxyConfigMap`, `addProxySidecar`, `configureRabbitMQBackendPort` + - Removes proxy when `shouldEnableProxy()` returns false + +## Key Functions + +### proxy.go + +- `ensureProxyConfigMap(ctx, instance, helper)` - Creates ConfigMap with embedded proxy script +- `addProxySidecar(instance, cluster)` - Adds proxy container to StatefulSet +- `buildProxySidecarContainer(instance)` - Builds container spec with TLS support +- `removeProxySidecar(cluster)` - Removes proxy sidecar +- `shouldEnableProxy(instance)` - Determines when proxy should be enabled +- `configureRabbitMQBackendPort(instance, cluster)` - Configures RabbitMQ to listen on localhost:5673 + +## Container Spec + +- **Image**: `quay.io/openstack-k8s-operators/openstack-operator-client:latest` +- **Command**: `python3 /scripts/proxy.py` +- **Args**: + - `--backend localhost:5673` + - `--listen 0.0.0.0:5672` + - `--tls-cert /etc/rabbitmq-tls/tls.crt` (if TLS enabled) + - `--tls-key /etc/rabbitmq-tls/tls.key` (if TLS enabled) + - `--tls-ca /etc/rabbitmq-tls-ca/ca.crt` (if CA specified) +- **Resources**: + - Requests: 128Mi memory, 100m CPU + - Limits: 256Mi memory, 500m CPU +- **Probes**: TCP liveness and readiness on port 5672 + +## Usage + +### Automatic (during upgrade) + +The proxy is automatically enabled when upgrading RabbitMQ: + +```yaml +apiVersion: rabbitmq.openstack.org/v1beta1 +kind: RabbitMq +metadata: + name: rabbitmq + annotations: + rabbitmq.openstack.org/target-version: "4.2.0" +spec: + queueType: Quorum + tls: + secretName: rabbitmq-tls +``` + +### Manual activation + +Force proxy activation with annotation: + +```bash +kubectl annotate rabbitmq rabbitmq \ + rabbitmq.openstack.org/enable-proxy=true +``` + +### Manual deactivation + +After dataplane reconfiguration: + +```bash +kubectl annotate rabbitmq rabbitmq \ + rabbitmq.openstack.org/clients-reconfigured=true +``` + +## Monitoring + +Check proxy logs: +```bash +kubectl logs rabbitmq-server-0 -c amqp-proxy +``` + +Proxy prints statistics every 5 minutes: +``` +=== Proxy Statistics === +Total connections: 25 +Queue rewrites: 120 +Exchange rewrites: 15 +Bytes forwarded: 5,432,100 +``` + +## Upgrade Workflow + +1. **Start upgrade**: Set target-version annotation → Proxy enabled +2. **Cluster recreated**: RabbitMQ 4.2 with quorum queues + proxy sidecar +3. **External services**: Continue using `amqp_durable_queues=false` +4. **Proxy rewrites**: Frames rewritten to use durable queues +5. **Dataplane reconfig**: Update services to `amqp_durable_queues=true` +6. **Set annotation**: `clients-reconfigured=true` → Proxy removed +7. **Direct connection**: Services connect directly to RabbitMQ + +## Important Notes + +### Proxy Script Location + +The proxy script is located at: +- `internal/controller/rabbitmq/data/proxy.py` + +When updating the proxy: +1.
