A demonstration Kubernetes cluster configuration.
This demo cluster configuration includes a script to install the Traefik Helm chart and then deploy services with kubectl. It uses Traefik to forward paths starting with /api/ to a demonstration Go API service. This is a service that I wrote and set up to test and build and push a container image to ghcr.io/joberly/demo-go-api:latest. The only endpoint available via this cluster setup is /api/rand?min=<int64>&max=<int64>. This configuration uses path stripping Traefik middleware and a special Traefik ingress route to strip the /api/ from the URL to forward those requests to the demo-go-api service. All other paths are routed to the site service running plain nginx using a standard Kubernetes ingress.
You may want to install the Traefik Helm chart yourself. Otherwise the deploy.sh script will attempt to do it and then deploy all services in the cluster.
Once everything is deployed, Traefik routes from localhost:80.
