📄 YAML

Stands for “YAML ain’t markup language”. It has 3 key points:

It’s case sensitive.
It’s a data serialisation language which means it stores data in form of code. Later using these files we deserialise. It’s similar to JSON and XML.
It only stores data no commands. So basically it’s a data format to exchange data.

It’s used for writing configuration files for Docker and Kubernetes Services.

Benefits:

Human readable
Strict syntax and indentation. Using tools like “ValidKube” you can validate YAML files easily.
Easily convertible to JSON or XML
Preferred for representing complex data
Parsing is easy

Sample YAML file:

# key-value pairs
”key”:“value”

- - - #separator to indicate different objects

# list
- apple
- mango
- lime

— - -

# block
cities:
 - delhi
 - mumbai

- - -

random: [“hello”, 100]
