Overview of this book

Containers and Kubernetes containers facilitate cloud deployments and application development by enabling efficient versioning with improved security and portability. With updated chapters on role-based access control, pod identity, storing secrets, and network security in AKS, this third edition begins by introducing you to containers, Kubernetes, and Azure Kubernetes Service (AKS), and guides you through deploying an AKS cluster in different ways. You will then delve into the specifics of Kubernetes by deploying a sample guestbook application on AKS and installing complex Kubernetes apps using Helm. With the help of real-world examples, you'll also get to grips with scaling your applications and clusters. As you advance, you'll learn how to overcome common challenges in AKS and secure your applications with HTTPS. You will also learn how to secure your clusters and applications in a dedicated section on security. In the final section, you’ll learn about advanced integrations, which give you the ability to create Azure databases and run serverless functions on AKS as well as the ability to integrate AKS with a continuous integration and continuous delivery (CI/CD) pipeline using GitHub Actions. By the end of this Kubernetes book, you will be proficient in deploying containerized workloads on Microsoft Azure with minimal management overhead.

6. Securing your application with HTTPS

HTTPS has become a necessity for any public-facing website. Not only does it improve the security of your website, but it is also becoming a requirement for new browser functionalities. HTTPS is a secure version of the HTTP protocol. HTTPS makes use of Transport Layer Security (TLS) certificates to encrypt traffic between an end user and a server, or between two servers. TLS is the successor to the Secure Sockets Layer (SSL). The terms TLS and SSL are often used interchangeably.

In the past, you needed to buy certificates from a certificate authority (CA), then set them up on your web server and renew them periodically. While that is still possible today, the Let's Encrypt service and helpers in Kubernetes make it very easy to set up verified TLS certificates in your cluster. Let's Encrypt is a non-profit organization run by the Internet Security Research Group and backed by multiple companies. It is a free service that offers...
