Porting to Kubernetes, course BAWJK

Everything is Kubernetes these days. So we ported the original BAWJ course to a Kubernetes environment ar.jl, in our case MicroK8s running on Ubuntu 20.04.

Course Title

Building Business Application with Julia in MicroK8s.

Basic Idea

  • Using MicroK8s;
  • Retain the original modules AppliSales.jl, AppliAR.jl, and AppliGeneralLedger.jl;
  • Communication via TCP sockets;
  • Pluto.jl notebook as interface.

Audience

This course is Julia programmers who are familiar with the principles from the course BAWJ.

Course design

The course design follows a lecture/lab task-oriented approach.

Course goals

This course will teach you how to:

  • Install MicroK8s on Ubuntu 20.04.
  • Activate Istio, Registry, Storage, DNS, and Dashboard.
  • Write communication software using TCP sockets.
  • Store AppliAR and AppliGeneralLedger Docker images on MacroK8s registry.
  • Install ArgoCD.
  • Write and test Kubernetes YAML files.
  • Create an ArgoCD application.

Online course, BAWJ

We started with the project rbontekoe/RbO.jl. to build up experience with Julia, based on the ports and adapter design pattern. The publisher-subscriber model was chosen, which resulted in the RbO.jl package. With Documenter.jl we wrote the documentation for the module. It also gave us the idea to write courses with Documenter.jl, and developed a tutorial as a test.

There are many excellent online courses nowadays. The content mainly consists of videos, and a syllabus is often missing. We experience it as a problem when you quickly want to look up some code. We will try to combine these two: videos in a curriculum.

Course Title

Developing Business Applications with Julia.

Basic Idea

  • Identifying the processes of a training center;
  • The workflow of the specialties registration and course evaluation.

Audience

This course is for starting Julia programmers with some basic knowledge of the programming language.

Course design

The course design follows a lecture/lab task-oriented approach.

Course goals

This course will teach you how to:

  • Designing a specialty using the ports and adapter design pattern.
  • Implementing the design, using:
    • Struct's,
    • Multiple Dispatch.
  • Defining test software.
  • Using Channels for inter-process communication.
  • Using REST API for human interaction
  • Turn the code into a Julia module.
  • Using GitHub to upload the software.
  • Create a Dockerfile using the official Julia Image.
  • Enable an SSH connection to containers using certificates.
  • Using Docker Compose to create the containers of the application.
