Killercoda is an interactive learning platform which allows everyone to access Linux|Kubernetes based environments just in their browser.

Courses

One of the most requested feature by creators was to bundle scenarios into groups|courses for better organisation. This is now possible on Killercoda!

HOW TO GET STARTED

General Creator Workflow

How does the scenario creation work on Killercoda?

Have a Github repository with scenarios
Add that repository to your Killercoda profile
Every time you push to the repository, your scenarios will be updated
Write the scenarios in for example JSON, Markdown and Bash

Subdirectory

The simplest way of grouping scenarios into a course is by just putting them into the same subdirectory.

Structure.json

To have more control over the structure it’s also possible to create a structure.json file in any subdirectory or top-level:

Once a structure.json is available, only the information from that file will be used. Any scenario or directory that exists outside the structure.json will be ignored.

Using a structure.json we can for example:

Control sort order
Reference scenarios from different courses or directories
Override scenario attributes like title or description
Exclude some directories

Simple Example

It can for example look like this:

{
  "items": [
    { "path": "scenario2" },
    { "path": "course1", "title": "Override title of course ONE" },
    { "path": "course2" }
  ]
}

Here we’ll only consider the three folders scenario2, course1 and course2. And for course1 we override the title.

Advanced Example

{
  "title": "Course TWO has a nice title",
  "description": "This is the description of course TWO",
  "items": [
    { "path": "scenario3" },
    { "path": "scenario4" },
    { "path": "../course1/scenario1" },
    {
      "path": "../course1/scenario2",
      "title": "New title for scenario TWO",
      "description": "Set a course description"
    }
  ]
}

Here we’ll even include some scenarios from another course (another directory) into our course.

Katacoda Courses/Pathways

We decided against supporting Katacoda Courses/Pathways due to its unnecessary complexity. We think it’s possible to do everything with the simpler structure-based layout on Killercoda. If that’s not the case reach out to us and let us know of your use-case.

The End

Let us know on SUPPORT if something doesn’t work or if you have any feature requests.
