Video

About the Talk

You’ve deployed an application and a few microservices into your Kubernetes cluster and now you’re wondering how to configure the workloads so that they communicate with one another, and more importantly, how to expose your application to the internet. This talk will show you how to use Kubernetes Services to enable communication between your workloads and how to configure your application so it can accept traffic from the internet.

What You’ll Learn

  • The difference between the kinds of Kubernetes Services
  • How to use the ClusterIP service to enable internal communication between workloads
  • How to use the LoadBalancer service to expose an application so it is reachable from the internet

This Talk Is Designed For

  • Anyone running containerized workloads in a non-Kubernetes environment
  • Anyone looking to gradually migrate to Kubernetes
  • Anyone interested in how Kubernetes microservices communicate with one another

Prerequisites

  • You have containerized an application or microservice
  • You have basic knowledge of containers and Kubernetes
  • You are familiar with Kubernetes Deployments
