🔥 Fix Kubernetes Resource Overcommit (Stop Wasting Money Instantly)

Cloud costs suddenly spiking?

Pods running… but barely doing anything?

👉 You’re likely facing Kubernetes resource overcommit.

And it’s one of the biggest hidden problems in modern clusters.

---

🧠 The Problem

Most teams deploy apps like this:

resources:
  requests:
    cpu: "2"
    memory: "2Gi"

👉 But actual usage is often:

CPU: 0.2
Memory: 200Mi

💰 Result:

• Wasted nodes
• Higher AWS bills
• Poor scaling decisions

---

🔍 Root Cause

• Overestimated resource requests
• No monitoring of real usage
• Static scaling assumptions

🍳 CloudChef Recipe: Fix Overcommit Fast

💡 Tip: Copy commands directly

---

🔥 Step 1: Check Actual Usage

kubectl top pods

---

⚡ Step 2: Adjust Requests

resources:
  requests:
    cpu: "200m"
    memory: "256Mi"

---

🚀 Step 3: Add Limits

limits:
  cpu: "500m"
  memory: "512Mi"

---

📈 Step 4: Enable Autoscaling

kubectl autoscale deployment my-app --cpu-percent=70 --min=2 --max=10

---

⚠️ Important Considerations

• Too low requests → throttling
• Too high → wasted cost

---

⚡ Best Practices

• Use real metrics
• Monitor continuously
• Use HPA or Karpenter

---

🚫 Common Mistakes

• ❌ Setting high defaults blindly
• ❌ Ignoring metrics
• ❌ Not using autoscaling
