Learnk8s and NGINX are launching a month-long, free educational program on Kubernetes networking.

The course is divided into four parts:

- Unit 1: Architecting Kubernetes clusters for high-traffic websites (the 7th of March)
- Unit 2: Exposing APIs in Kubernetes (the 14th of March)
- Unit 3: Microservices Security Patterns (the 21st of March)
- Unit 4: Advanced Kubernetes Deployment Strategies (the 28th of March)

Each part has:

- A live webinar (Chris, Salman & Andrea will present those). The event is recorded, and you can catch up later too.
- A self-paced lab for experimenting with Kubernetes technologies. Nginx will provide interactive labs via Instruqt.
- A step-by-step tutorial where you can try everything on your computer too (and maybe copy and reuse the code).
- Extra links and resources to help you understand and dig deeper into the subjects.

You can read the full agenda here: https://www.nginx.com/c/microservices-march-2022-kubernetes-networking-agenda/

A typical web application responds to requests from bots, health checks, and various attempts to circumvent security and gain unauthorized access.

Examples include:

- SQL injections.
- XSS attacks.

So, how can you filter out those malicious attempts in Kubernetes?

You have at least 2 solid options:

1. You can filter the traffic before it reaches the container.
2. You can filter the traffic at the Ingress.

Chris Nesbitt-Smith will dive into the details this coming Monday at 8am PT / 4pm CET in a live webinar.

After the session, you will have access to the code, a step-by-step tutorial and interactive labs to test the configuration (provided by NGINX).
