go-rust

One Rust and one golang microservice that are deployed to microk8s. There is a cron job defined on the cluster that runs every minute and calls a random enpoint on a microservice. Each microservice has an endpoint /die that will cause the pod to die forcing the HorizontalPodAutoscaler to create a new pod.

prometheus methics

Each microservice has a /metrics endpoint that is scraped by prometheus. The prometheus server is deployed to the cluster and is configured to scrape the microservices.

1. publish metrics of service kill calls (prometheus?/kafka?) => kafka

2. create a reactive be4fe(?) that handles websocket connections to push messages to a UI (react?) that shows when a service is killed
