KISS, DRY ‘n SOLID — Yet another Kubernetes System built with Ansible and observed with Metrics Server on arm64
This blog post shows how a plain Kubernetes cluster is automatically created and configured on three arm64 devices using an orchestration tool called Ansible. The main focus relies on Ansible; other components that set up and configure the cluster are Docker, Kubernetes, Helm, NGINX, Metrics Server and Kubernetes Dashboard. Individual steps are covered more or […]
In today’s world, video conferencing is getting more and more important – be it for learning, business events or social interaction in general. Most people use one of the big players like Zoom or Microsoft Teams, which both have their share of privacy issues. However, there is an alternative approach: self-hosting open-source software like Jitsi […]
Dockerizing an existing application and deploying it in a Kubernetes Cluster via Rancher to achieve better scalability and cost minimization. Load Testing with Artillery, Monitoring with Prometheus & Grafana and GitHub Actions for CI/CD were used in the process.
by Jannik Igney [ji016] & Timothy Geiger [tg079] 1. Introduction For our course “Software development for cloud computing” we developed a little multiplayer browser game named “GeoDarts”. Goal of the game: Guess where cities are located in Germany on a map and be closer than your opponents. Goal of our project: We wanted to learn […]
In this blog post we are taking a look at scaling possibilities within Kubernetes in a cloud environment. We are going to present and discuss various options that all have the same target: increase the availability of a service.
This is part two of our series on how we designed and implemented a scalable, highly-available and fault-tolerant microservice-based Image Editor. This part depicts how we went from a basic Docker Compose setup to running our application on our own »bare-metal« Kubernetes cluster.
This is part one of our series on how we designed and implemented a scalable, highly-available and fault-tolerant microservice-based Image Editor. The series covers the various design choices we made and the difficulties we faced during design and development of our system. It shows how we set up the scaling infrastructure with Kubernetes and what we learned about designing a distributed system and developing a ‘production-grade’ Kubernetes cluster running on multiple nodes.

Cloud computing has so much potential that the possibilities seem to be endless. Without knowing much about it the cloud looks like a magic place for many people. To give you a more detailed explanation we sum up the design process of our cloud application step by step in the following blog post. Without giving […]
