Imagine your Kubernetes API is a nightclub.

Every request (or person) wants in.

Before that happens, they face the bouncer — Admission Controllers.

These powerful components intercept API requests before they're persisted in etcd.

Types:
🔁 Mutating Admission Controllers — Modify the request object.

✅ Validating Admission Controllers — Approve/deny based on policies.

Use them for:

• Sidecar injection
• Enforcing security rules
• Labeling workloads

🛠️ Tools like Kyverno and OPA Gatekeeper make writing policies easier.

📌 Pro tip: Admission controllers are the first line of defense. Use them wisely!
