Transform values per environment (e.g., <code class="bg-white px-3 py-1 rounded font-mono text-purple-600 font-semibold">preprod-*</code> namespaces get preprod API URLs, <code class="bg-white px-3 py-1 rounded font-mono text-purple-600 font-semibold">prod-*</code> get production URLs).

|
||||
# ==========================================
|

# 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%.
|
||||

# 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

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}
