About This Kubernetes Cluster
This website is hosted on a bare metal Kubernetes cluster that I built using Raspberry Pi's. In this cluster I run various experiments and stats you see here are directly taken via KubernetesClient.
Including this UI and gRPC backend pods to present this portfolio
MetalLB as load balancer,
Traefik for ingress controller,
Let's Encrypt for certificates
Including a Docker private image registry
For various tasks like getting image of the day
Used 5 Raspberry Pi's and a NAS. I can easily add new devices when needed
Tech Stack
This is the tech I used to deploy this system. Highlights what I'm proficient at.
You can check the source code at my GitHub!
Kubernetes
Proudly self-hosted at my Raspberry Pi 5-4 cluster! Nodes are prepared and cluster deployed with a single Ansible command.
Ansible
I felt this Kubernetes setup would be incomplete without fully automating nodes. Also encourages experimentation since I can reset the lab rapidly if things break beyond repair.
Docker
Deployed with Docker images. My all public images are at my DockerHub account. My private images are in this cluster, at Docker private image registry.
.Net 10 & Blazor
This project is created with Domain Driven Design in mind and uses latest .Net + Blazor features.
Go
If writing a cron with just yaml is not practical, I write it with Go. For trying out other languages to widen my view.
gRPC
Wanted to try something other than REST, used gRPC and liked it.
PostgreSQL
Current database. I like Its features and like to experiment with it.
OpenTelemetry
Traces are a must
Prometheus
Using it for 4+ years but I wanna sink more time specifically into it
Grafana
This cluster wouldn't be complete without mesmerizing dashboards of Grafana
Seq
For displaying logs with traces. Has a simple an nice UI.
Lens
Using it to observe the cluster in a more graphical way. Thinking about trying K9s later. Especially for colored logs
Kubecolor
Mentioning this because it's a must have. It colors all the kubectl output, including logs of the pods!
Elastic Search
Using for Jaeger for persistency
Authentik
Securing access to my panels with it
Resume
I'm a dedicated engineer committed to writing clean and efficient systems while always being mindful of deadlines.
I take pride in mentoring junior colleagues, guiding them patiently and deriving satisfaction from watching them grow into proficient engineers.
My enthusiasm for learning never wanes; delving into new systems excites me, and I continuously seek innovative methods to refine my development process.
