YAML Tutorial for DevOps engineers | YAML Syntax explained with real examples
► Subscribe To Me On KZhead: bit.ly/2z5rvTV
In this complete YAML tutorial you will learn what YAML is, what it's used for and I demonstrate the basic YAML syntax with real Kubernetes configuration files.
YAML stands for YAML Ain't Markup Language and is a data serialization language. The basic building block of YAML documents are key-value pairs. Indentation is used to denote structure and tabs are not allowed.
In all my tutorial videos for Docker, Kubernetes, Ansible etc. I've used YAML for the example configuration files, because YAML has actually become a widely used format for writing configurations files. One of the reasons for its popularity is that the language is human-readable, intuitive and flexible. In fact, it can be used with nearly any application that needs to store or transmit data.
In this Yaml Tutorial I cover the below:
▬▬▬▬▬▬ T I M E S T A M P S
0:00 - Intro
0:11 -YAML is popular
0:36 - What is YAML?
1:13 - Why learn YAML? YAML Format compared to XML and JSON
2:37 - YAML Use Cases
2:52 - YAML Syntax
2:56 - key-value pairs
3:56 - comments
4:18 - objects
5:31 - lists
5:51 - boolean
6:21 - more about lists
8:48 - Real Kubernetes YAML Configuration Example
11:54 - Multi-line strings
15:15 - environment variables
16:07 - placeholders
16:42 - multiple yaml documents
17:17 - YAML and JSON in Kubernetes

  • I never get tired of listening to your tutorials. you explain things in detail. the most important thing in your tutorials and that makes them special is you start giving historical declarations at the beginning like why it was introduced in our IT world. To me, it is a very very important element of any tutorial. knowing why it was introduced.

  • YAML has one idiosyncrasy regarding list indentation that I don’t really like, but whichever you choose - be consistent. You can even see this variation in how list indentation can be expressed at 8:09 (happens to me a lot by accident, too). So, apparently with YAML lists, you can actually put the dash/hyphen at the SAME indentation level as the parent. You just have to ensure that the first attribute (e.g. “app” in your example) and all other attributes under it are still indented by the same amount (e.g. if you’re using 2 spaces for indentation, the dash takes up one space, then one space after that, then the first attribute). Then subsequent attributes are _also_ still indented with 2 spaces relative to the parent. It’s more dense and even if you’re using normal 2 space indentation, it’s more of a subjective decision: Which do *you* choose? E.g. When you conceptualize a list, does the list itself start indented at the dash or is it’s indentation location dictated by the list contents? 🧐
