Day 28 of DevOps learning 🚀 :

As part of my DevOps journey, I recently delved into Kubernetes Ingress and its role in managing external access to services in a Kubernetes cluster.

What is Ingress? Ingress is an API object that provides a way to expose HTTP and HTTPS routes from outside the cluster to services within the cluster. Instead of exposing services individually, you can consolidate the routing and load balancing using Ingress, streamlining traffic management.

Why Ingress?

Efficient handling of external requests to services.

Enables path-based routing, allowing multiple services to be served under the same domain.

Supports SSL termination, enhancing security.

Load balancing for better traffic management and reliability.

My Key Takeaways:

Ingress Controller is essential to manage Ingress resources—it's the gateway through which the traffic flows.

Ingress Rules define how requests are directed to specific services based on URL patterns.

Handling traffic externally becomes simpler with Ingress compared to NodePort or LoadBalancer.

Integrating TLS with Ingress for secure communications (SSL termination) was an interesting experience!

I also explored how Ingress works with Services and Pods, allowing external clients to access the cluster smoothly.
