However, when it comes to complex data structures, XML is far more useful. So, people started using the latter which is currently pretty popular. While XML is better structured, it has a higher overhead compared to JSON. XML and JSON are pretty popular for web development and JavaScript language.

How is YAML Related to JSON and XML?īefore we jump in let’s look at how YAML compares with two other popular serialization languages, XML and JSON. However, I’ll be taking a deeper dive to illustrate how YAML files are structured, written, and implemented in Kubernetes systems. This encapsulates the essence of YAML and its usage with Kubernetes. This is because it is easy to understand by different people, the structure is pretty simple, and overall, more flexible. Many times, JSON files are also used for the same purpose but YAML is becoming increasingly popular. They dictate how a pod should run, interact with other objects, and more. In Kubernetes, YAML is a manifest file, which performs the functions mentioned above. In the context of Kubernetes, YAML files are mainly used for the configuration of K8 pods, services, and deployments. These are essentially plain text files used for converting programming languages into a format that can be stored, transmitted, distributed, and reconstructed. YAML stands for “Yet Another Markup Language”.
