YAML

 YAML

As mentioned earlier, YAML (Yet Another Markup Language) is a human-readable programming language. YAML syntax is used to express the Ansible playbooks.

Here are some basic concepts of YAML.

• Key/Value pair:

Dictionary is represented in key/value pairs.

• • Example:

james:
name: james john
rollNo: 34
div: B
sex: male

• Representing lists:

Each element in a list has to be written in a new line with ‘-‘ as a prefix.

• • Example:

countries:
- America
- China
- Canada
- Iceland

• Lists inside a dictionary:

We can have lists inside a dictionary.

• • Example

james:
name: james john
rollNo: 34
div: B
sex: male
likes:
