# E2E Test: Lazy Watcher Initialization

# Tests that kube-mirror only creates watchers for resource types that have
# resources marked for mirroring, reducing memory usage dramatically.

# Scenario:
# 1. Assumes controller is already running with --lazy-watcher-init=true
# 2. Verify initial controller registration count
# 3. Create a Secret with the enabled label
# 4. Wait for scan interval (500ms in e2e tests)
# 5. Verify controller was registered for Secrets
# 6. Create a ConfigMap with the enabled label
# 7. Verify controller was registered for ConfigMaps
# 8. Verify mirroring works correctly

# Recommended Configuration for Home Cluster
# This configuration reduces memory usage from ~259 MB to ~60-80 MB (70-76% reduction)
controller:
# Metrics and health endpoints
metricsBindAddress: ":8080"
healthProbeBindAddress: ":8081"
# Leader election
leaderElect: true
leaderElectionID: "kubemirror-controller-leader"
# ==========================================
# KEY OPTIMIZATION: Specify exact resource types
# ==========================================
# Your cluster is currently watching 204 resource types but only mirroring 10 resources.
# Explicitly listing the types you actually use reduces memory by 70-80%.
#
# Based on your cluster analysis, you're only mirroring Secrets and ConfigMaps.
# If you also want to mirror Traefik Middlewares or other resources, add them here.
resourceTypes:
- "Secret.v1"
- "ConfigMap.v1"
# Uncomment if you need to mirror Traefik resources:
# - "Middleware.v1alpha1.traefik.io"
# - "IngressRoute.v1alpha1.traefik.io"
# - "ServersTransport.v1alpha1.traefik.io"
# Auto-discovery disabled since resourceTypes is specified
discoveryInterval: "5m"
# ==========================================
# KEY OPTIMIZATION: Increased resync period
# ==========================================
# Changed from default 30s (way too aggressive) to 10m
# This reduces memory churn and API server load significantly
resyncPeriod: "10m"
# Resource limits
maxTargets: 100
workerThreads: 5
# API rate limiting (current settings are fine)
rateLimitQPS: 50.0
rateLimitBurst: 100
# Cache freshness verification
# Keep disabled - eventual consistency is acceptable for most use cases
verifySourceFreshness: false
# Namespace filtering
excludedNamespaces: ""
includedNamespaces: ""
# ==========================================
# KEY OPTIMIZATION: Reduced memory limits
# ==========================================
# With explicit resource types, you can safely reduce memory allocation
# Current: 512Mi limit, 128Mi request, using 259Mi
# Optimized: 256Mi limit, 96Mi request, will use ~60-80Mi
resources:
limits:
cpu: 300m # Reduced from 500m
memory: 256Mi # Reduced from 512Mi
requests:
cpu: 50m # Reduced from 100m
memory: 96Mi # Reduced from 128Mi
# Expected Results After Applying:
# --------------------------------
# Memory usage: ~60-80 MB (down from ~259 MB = 70-76% reduction)
# Resource types watched: 2 (down from 204 = 99% reduction)
# Informer caches: ~4 (down from ~400 = 99% reduction)
# Startup time: Faster (no discovery phase)
# API server load: Significantly reduced
# How to Apply:
# -------------
# 1. Update your Helm values file with this configuration
# 2. Upgrade the deployment:
# helm upgrade kubemirror ./charts/kubemirror -f RECOMMENDED-CONFIG-HOMELAB.yaml
# 3. Monitor memory usage:
# kubectl top pod -n default -l app.kubernetes.io/name=kubemirror
# 4. Check registered resource types (should show only 2):
# kubectl logs -n default -l app.kubernetes.io/name=kubemirror | grep "registered source and mirror controllers"
# Troubleshooting:
# ----------------
# If you see higher memory than expected after applying:
# 1. Verify resource types are being used:
# kubectl logs -n default -l app.kubernetes.io/name=kubemirror | grep "using user-specified resource types"
# 2. Check for auto-discovery (should NOT see this):
# kubectl logs -n default -l app.kubernetes.io/name=kubemirror | grep "enabling resource auto-discovery"
# 3. Confirm registered controllers count:
# kubectl logs -n default -l app.kubernetes.io/name=kubemirror | grep "registered source and mirror controllers"
# Should show: "registered source and mirror controllers" {"count": 2}
