Migrating from Heroku to Hetzner: Achieving Scalability with Docker, Kubernetes and Rancher
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.
How to create a K8s cluster with custom nodes in Rancher
Don’t you find it annoying not to be able to manage all your Kubernetes clusters at a glance? Ranger 2.0 offers an ideal solution. The following article is less a scientific post than a how-to guide to creating a new Kubernetes cluster with custom nodes in Ranger 2.0. But before we drift into the practical…
WebAssembly: Das neue Docker und noch mehr?
If WASM+WASI existed in 2008, we wouldn’t have needed to created Docker. That’s how important it is. Webassembly on the server is the future of computing. A standardized system interface was the missing link. Let’s hope WASI is up to the task! Tweet, Solomon Hykes (Erfinder von Docker), 2019 Dieser Tweet über WebAssembly (WASM) des…
“Himbeer Tarte und harte Fakten”: Im Interview mit Ansible, k3s, Infrastructure as Code und Raspberry Pi
Why so serious? – Ein Artikel von Sarah Schwab und Aliena Leonhard im Rahmen der Vorlesung Systems Engineering and Management. Die Idee, ein fiktives Interview zu erstellen, entstammt daraus komplexe Sachverhalte unterhaltsam und verständlich zu machen. Wir sind heute zu Gast in der Tech-Sendung “Himbeer Tarte und harte Fakten”. Heute geht es unter Anderem um…
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…
Kubernetes: from Zero to Hero with Kompose, Minikube, k3sup and Helm — Part 2: Hands-On
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.
