KPA - The Knowledge Pods Approach

GitHub Actions CI

This repository defines the Knowledge Pods Approach (KPA), an agile way to create, maintain and evolve training materials and presentations using standard markdown files to create beautiful slide sets and agendas.

What is KPA

The Knowledge Pods Approach (KPA) is a method for creating training materials, presentations and documentation that separates the content creation (the knowledge) from their presentation (the files, i.e. pdf, ppt and html).

KPA relies on the standard markdown file format, which means that there will be no need to rely on proprietary tools and formats to create contents.

KPA helps to concentrate on what matters most: the knowledge.

KPA is at the same time:

What is a KPA project

A KPA project is a set of variables and markdown files that are used by the Ansible role named kpa_generator to automate the creation of a single combined markdown file that can be processed by Marp (Markdown Presentation Ecosystem) to obtain a set of slides in the usual presentation formats like html, pdf and ppt. The kpa_generator Ansible role generates also an agenda markdown that is converted to a PDF using the Pandoc tool.

KPA makes it possible to control all the knowledge in a standard and "edit from everywhere" way, making it easy to compose and mix the set of topics you want to include into the training, by creating sequences of Knowledge Pods (KP).

What is a Knowledge Pod

A Knowledge Pod (KP) is the smallest part you can split a section of a training or of a presentation.

You can imagine it as a chapter. For example, if you need to deliver a training named "How to use my technology" in which you'll have to cover an introduction to your technology, the prerequisites, the installation and finally day 0 operation, then each one of these chapters would be a Knowledge Pod, like:

  • Introduction.md
  • Prerequisites.md
  • Installation.md
  • Day-0-operations.md

A Knowledge Pod should have, uniformly, the same duration (say one hour), so that it will be easy to compose a training by picking the needed KPs.

Each section of a Knowledge Pod, say a paragraph, is separated from the other with the --- Markdown element, which represents a new slide.

What are the benefits of adopting KPA

There are several benefits using KPA:

  • Concentrate just on the contents: once you have defined your project, you don't need to care about anything but writing Knowledge Pods. No need to manually syntax highlight your code blocks, no need to adapt text, no need to duplicate your slide to modify just a simple sentence. Just write your Knowledge Pods in Markdown and you're good to go.
  • Compose training and presentations dynamically: no more Power Point slides cut and paste. You can combine your Knowledge Pods in the way that fits your needs, creating as many variants of your training and presentations as you need.
  • Have the same look & feel for every training or presentation: no more "Ok, now you need to apply this new slide format to all our 100 presentations". You will define your project look & feel one time and it will be applied everywhere, always the same way.
  • Use a standard and reusable format: the same documentation you will produce with KPA could be used wherever you want because it's markdown, which is a standard, and you will be able to write your own tool to manage your Knowledge Pods.
  • Keep everything versioned and in order: once you'll store your KPA projects in a Git repository, you'll get versioning, monitoring of the changes and your entire knowledge in one traceable place.
  • Let everyone do their job: Markdown is simple to the point that even non-technical people can edit Knowledge Pods and this allows for everyone to do their job: graphics can work on the themes, instructors can write the contents and you, the KPA master ©, will put everything together.

> cd kpa

You'll see a projects directory, which is meant to contain all your KPA projects. You can use example project as your starting point.

This is the structure of a KPA project:

projects/example/
├── common
│   ├── settings.yml
│   ├── example.tex
│   └── theme.css
├── images
│   ├── chapter-background.png
│   ├── cover-background.png
│   ├── logo.png
│   └── slide-background.png
├── templates
│   ├── chapter.md.j2
│   └── cover.md.j2
├── contents
│   ├── Topic-10.md
│   ├── ...
│   └── Topic-18.md
└── Example-Training-01.yml

Where:

  • common: is the home for shared training/presentation files:

    • theme.css is the css theme file that overrides Marp's default theme. This is not needed, you can use a predefined Marp theme.

    • example.tex is the Pandoc texfile template. This is not strictly needed, but to get the best from the generated agenda pdf a Pandoc template is more than reasonable.

    • settings.yml is mandatory and contains the general presentation parameters that will override role's defaults:

  • images contains backgrounds, logos and all the useful graphics elements for the slides.

  • templates contains the templates for the special slides that will be processed by Ansible. These templates will parse the variables, to be reusable. For example, the chapter.md.j2 contains the layout for the slide that will be shown at the beginning of each KP/Chapter:

    ---
    
    <!-- _backgroundImage: url({{ marp_chapter_background_image }}) -->
    
    # <span class="txt-yellow">{{ slide.title }}</span>
    
    <span class="txt-yellow">{{ slide.chapter }}</span>

    The variables used in this file can be declared globally (like marp_chapter_backgroundImage, see slides-settings.yml) or specifically (like slide.title, see Example-Training-01.yml).

  • contents contains the Knowledge Pods in the Marp Markdown compatible format (The main rule: --- is the beginning of a new slide).

  • Example-Training-01.yml is the slides set declaration, it contains the structure of the document, in a list element:

    ---
    
    # KPA
    kpa_title: "My spectacular course"
    kpa_contents: "{{ kpa_project_dir }}/contents"
    kpa_slides:

      - cover: true
        title: "{{ kpa_title }}"

        ...
      - chapter: 'DAY THREE - PART EIGHTEEN'
        title: 'Topic 18'

    # Output
    output_file: "slides/Example-Training-01"
    schedule_output_file: "{{ output_file }}.schedule.md"
    marp_output_file: "{{ output_file }}.md"

How to use the KPA container

KPA comes with a handy container that can be used to automate the creation of both the slides and the agenda PDF files.

Once you have a local project in place:

> ls -1
common
contents
Example-Training-01.yml
images
templates

You will need to launch the container by:

  • Mapping the project directory as a volume inside the /kpa/projects/<project name> container's directory.
  • Mapping the output directory (in this example /tmp) inside the /kpa/output container's directory.
  • Pass the --project <project name> (in this example example) and --yml <kpa document yaml> (in this example Example-Training-01.yml) options.

Your command line will be something like this:

> docker run --rm \
  -v $PWD:/kpa/projects/example \
  -v /tmp:/kpa/output \
  ghcr.io/mmul/kpa --project example --yml Example-Training-01.yml

After a really short time you should get:

Rendering example KPA project for Example-Training-01.yml file -> Completed.

The output files will be created in the output mapped directory (in this example /tmp):

> ls -1 /tmp/Example-Training-01.*
/tmp/Example-Training-01.agenda.md
/tmp/Example-Training-01.agenda.pdf
/tmp/Example-Training-01.md
/tmp/Example-Training-01.pdf

Note: in case of errors, it is possible to use the -v|--verbose option to get a more talkative output (in fact the ansbile-playbook output).

Results

The KPA container execution should produce these set of slides and agenda inside the mapped output directory:

  • Cover:

    images/slide-cover.png

  • Chapter:

  • Slide:

  • Agenda:

How to use KPA manually and in CI

The KPA container can be used interactively, and will give you an environment with all the tools needed to generate both slides and agenda, but it is also possible to use the kpa_generator Ansible role locally. Check the KPA manual commands document to learn how to use the tools manually.

If you are interested in a deeper way of integrating KPA you can check the Using KPA in CI document to understand how to use KPA in both GitHub and GitLab CI workloads.
