Let’s Encrypt Kubernetes
In the Cloud Native world, how can we be sure to create secure applications? The inherently dynamic environment with short-lived containers, orchestrators, and network encapsulation provides significant challenges to traditional network security tools and procedures.

Best practices for cloud architecture security generally fall into three categories: Authentication, Authorization, and Encryption. This session focuses on the latest Kubernetes methods for encrypting internal and external application traffic.

In this live demonstration, you will learn how to enable HTTPS (SSL/TLS) for applications deployed in Kubernetes. First we’ll walk through manually deploying and using TLS certificates in containerized applications. Then we’ll level-up our Kubernetes infrastructure by creating an automated certificate generator leveraging Let’s Encrypt, a free and open Certificate Authority. Finally, we will use our automatically created certificates to secure three services: NGINX, an Ingress Controller, and a Golang application.
