Master YAML fundamentals by reading and writing consistent configurations, linting syntax, and building playbooks and scripts. Explore editor setups, block and flow styles, and indentation to manage multi-document YAML files.
Learn to write and parse YAML using online parsers, explore key-value pairs, lists with dashes, and indentation rules to represent dictionaries, users, and departments, including error handling.
Learn to choose and configure text editors for YAML, ensuring proper indentation with spaces, avoiding tabs, and enabling syntax highlighting and auto indents for reliable YAML and Ansible playbooks.
Explore how yaml relies on consistent indentation and careful tab-to-space handling, using command line tools and editors like VS Code to avoid hidden characters and key-value confusion.
Install nano on linux, create the dot nano rc, set auto indent and two-space tabs for yaml, edit and validate files with nano and cat, and consider vim.
Explore configuring Vim with a .vimrc and dot vmmark file, enabling syntax highlighting and YAML-specific settings, then compare using Visual Studio Code for editing YAML files.
Explore the basic building blocks of YAML syntax, including block and flow styles for lists and mappings, scalars like strings, numbers, booleans, and nulls, and comments.
Explore YAML fundamentals by building sequences, mappings, and nested collections with scalars, and learn flow and block styles, indentation, and lists of mappings.
Explore yaml syntax, including document structures with start and end markers, anchors and aliases, and complex keys with sequences and mappings, plus compact nesting for streamlined data.
Explore how YAML tags explicitly declare data types, from untagged values to explicit string and timestamp tags, with examples of integers, floats, and hex data.
Explore YAML syntax through an end-to-end example including conference data, sessions, and attendee registration, using anchors, aliases, flow style sequences, and complex keys.
Explore YAML fundamentals for Ansible, including basic syntax rules, data types, lists and dictionaries, and practical lab examples using vim on a RHEL system.
Explore YAML syntax by combining lists and dictionaries through a practical, complex example of employees with names, ages, and skills, and extend to Ansible inventories and playbooks.
Create an ansible playbook in yaml to install httpd, open port 80 via firewall commands, and start and enable the Apache service on boot, with a reload firewall handler.
Understanding YAML is not something that comes naturally to everyone. When you first look at a YAML file, it may appear as though Python and someone's to-do list had a collision. You will gain an understanding of YAML files and get some practice writing in YAML by taking this course, which is titled "YAML Fundamentals Compete Course" You will begin by becoming familiar with the fundamental syntax of YAML. After that, you'll learn how to build more advanced structures by applying the fundamental syntax you just learned. After you have finished this training, you will have the knowledge of YAML as well as the abilities essential to use the language effectively in the day-to-day work you do in the information technology business.
The following is a synopsis of the topics covered in this class:
Course Overview. Basics of YAML Structure
Using Online Parsers
Choosing Text Editors and IDEs for YAML
The Problem with Tabs
Creating a .nanorc File
Creating a .vimrc File
Using VSCode
And more…
FYI: YAML is a human-readable data-serialization language. It is commonly used for configuration files and in applications where data is being stored or transmitted. YAML targets many of the same communications applications as Extensible Markup Language (XML) but has a minimal syntax which intentionally differs from SGML. It uses both Python-style indentation to indicate nesting, and a more compact format that uses [...] for lists and {...} for maps thus JSON files are valid YAML
