About the course
This course page is part of the COIL Course Cloud Computing of the master course Software Engineering Master (SEM) at the University of Applied Sciences in Heilbronn in Heilbronn, Germany, as well as the Business Information Systems (BIS) of the Vietnamese Germany University in Ho Chi Minh City, Vietnam as part of the COIL and Virtual Exchange program at Heilbronn University of Applied Sciences.
The goal is to develop a solution that is as holistic as possible. This includes the practical construction of a physical single-board computer cluster, which will be set up and put into operation as part of a joint exchange of students.
After this joint prelude, the students switch to collaborative online mode and design and install the software landscape for the administration, monitoring and operation of the built cloud platform, on which software developed by the course participants themselves is operated at the end of the project. The intercultural and geographically distributed environment will prepare the students for a real project environment.
This course page provides all companion material and results of the course.

During the first day a intercultural workshop took place, where the members of the team had plenty of time to get to know each other.
Further information on this will follow soon...
Day two is fully packed with technical challenges, where the teams are going to finish various tasks.
The tasks will be done by
- a hardware team where we build our own cloud based on a RaspberryPi cluster
- a Linux team responsible for the base system, hardening the base system and including everything in the Ansible scrips
- a Kubernetes team, responsible to install a Kubernetes base installation
- an Ansible team, responsible for creating automated tasks to set up the cluster (operating system, security, installing the Kubernetes on the cluster) and
- setting up a CI/CD pipeline by a automation team so everything the team creates is deployed automatically once checked in in Git.
For all teams, the three part guide Kubernetes Cluster on Raspberry Pi 4B might be a good starting point:
Part 1:
Part 2:
Part 3:
To get an idea of Kubernetes, check out the Kubernetes Overview.
Additional information about how to build a Kubernetes cluster on Ubuntu, you find at the Ubuntu tutorials How to build a Raspberry Pi Kubernetes cluster using MicroK8s .
The best way to get startet with Ansible is by doing it using the Ansible Community Documentation.
We do expect at least on Ansible playbook for installing the cluster. Why? As soon as you have finished the playbook, you will be able to install the cluster again, and again, and again within no time. Therefore changing (and messing around) with the cluster won`t hurt.
Finally, the cluster has to be installed by a GitLAb CI/CD pipeline.
Setting up the RaspberryPi Case is documented as at the Cluster Case Assembly Instructions.
Finally, the hardware available for the project is based on the blog of Rockford Lhotka blog.
Tasks:
- Create a Raspberry Cluster based on the hardware provided. The has tobe accessible via the very own wireless adaptor provided.
- Document the setup as well as important decisions so every team member could rebuild the setup
Bonus: The hardware team will join our hardware lab to add some LEDs and flashy lights to our cluster hardware in the afternoon!
- Set up the base installation for the cluster based on Ubuntu for ARM architecture
- Take care of hardening the system (no passwords, access via SSH keys only, make sure every team member get s access to the system, firewall. Fail2Ban etc.)
- Prepare every installation step so it can be put into Ansible task for automation
- Document the setup as well as important decisions so every team member could rebuild the setup
- Set up the basic Kubernetes installation for the cluster.
- At a minimum one administrator account has to be provided for the following workshop on day 3
- Document the setup as well as important decisions so every team member could rebuild the setup
- Set up a CI/CD pipeline in Git.
- After every check-in in git (probably on a very specific branch, e.g. release), the pipeline should be triggered and cause the cluster to be fully installed
- Document the setup as well as important decisions so every team member could rebuild the setup
- Confluence for documenting: https://confluence-student.it.hs-heilbronn.de/display/C2C2/c2c2
- HHN GitLab: https://git.it.hs-heilbronn.de (projects will be created as required)
- If not familiar with Git: https://www.udacity.com/course/version-control-with-git--ud123
Day three will be covered by a full day workshop about DevOps and Kubernetes held by Exxeta AG from Stuttgart.
Day 4 is split into 3 parts:
- Introduction to the follow up virtual COIL group work
- Guided tour of the VR Labs at our UniTyLab.
- Group Work and preparing your presentations
The task of the virtual group work will be to continue the work done so far by extending it with a small application hosted by your Kubernetes cluster.
-
You will develop a small web application in form of a guide tour for Ho Chi Minh City.
-
The application should consist of three part: database + backend + frontend.
-
Each team shall provide a different aspect of the application (frontend + backend).
-
Each part shall run in its own container.
-
All three containers shall be hosted in one Kubernetes pod.
-
You provide one service to connect to the pod.
-
The service shall expose port 80 to be reached.
-
The container images can be hosted in any repository you choose.
-
It is acceptable, that the images are build by hand and pushed to the repository manually.
-
Bonus: You implement another Pipeline that pushes the images automatically to the repository.
- Final presentation (15 Minutes each group)
- Retrospective of the week
- Excursion to Heilbronn Experimenta
- You will be able to ask any question during the project work via the forum in ILIAS
- There will be a set of syn meetings be offered online.
