What is YAML?

YAML (YAML Ain't Markup Language™) is a human-friendly data serialization language that can be used with any programming language. Its design prioritizes readability and simplicity, making it ideal for configuration files and data structures.

The current specification is YAML 1.2 (Revision 1.2.2, Oct 2021), which is widely supported by numerous frameworks and tools in virtually all popular programming languages, including JavaScript, Python, Java, Go, Ruby, and many more.

Its widespread adoption in modern technologies like Kubernetes, Docker Compose, GitHub Actions, and CI/CD systems demonstrates its versatility and effectiveness in representing structured data in a clear and maintainable way.

Example YAML for Kubernetes Pod:

# YAML Example
apiVersion: v1
kind: Pod
metadata:
  name: nginx
  labels:
    app: nginx
spec:
  containers:
  - name: nginx
    image: nginx:1.14.2
    ports:
    - containerPort: 80
  volumes:
  - name: config-volume
    configMap:
      name: nginx-config
