Showcase

To demonstrate some cluster functionality, I set up a demo application with 4 microservices, a web server & a database/cache (Redis).

The application can be accessed using the appdomain on https://aquarium.app.konst.fish/. (Ingress Source) The source code & Kubernetes manifests are in this git repo.

The app also features complete observability, part of the platforms offered functionality, which can be viewed here https://showcase-grafana.app.konst.fish/ (This is behind Zero Trust, all members of the GitHub Org are authorized)
