Kubernetes Ep 6: Ingress Controllers & HTTP Path Routing

Mon, 10 Aug 2026 00:30:00 +0000

While L4 Kubernetes Services handle IP and port-level load balancing, modern web applications require Layer 7 HTTP/HTTPS routing features: URL path matching (/api vs /app), hostname routing (api.example.com), SSL/TLS termination, and header rewriting. This is handled by Ingress.

Kubernetes Ep 5: Networking Services (ClusterIP, NodePort, LoadBalancer)

Mon, 10 Aug 2026 00:25:00 +0000

Pods are ephemeral—they are created, destroyed, and rescheduled dynamically, causing their IP addresses to change constantly. A Kubernetes Service provides a stable, persistent virtual IP (VIP), DNS name, and load balancing frontend across a dynamic set of backend Pods.

Docker Ep 3: Docker Networking Deep Dive

How do two containers on the same host talk to each other without exposing ports to the public internet? Docker uses Linux virtual network interfaces (veth pairs) connected to a software bridge.

CKAD Ep 4: Services, Ingress & Network Policies

Sun, 09 Aug 2026 14:15:00 +0000

Services provide stable IP addresses for ephemeral Pods, Ingress controllers route HTTP/S domain traffic at Layer 7, and NetworkPolicies act as Pod-level firewalls. In this episode, we build production manifests for all three.
