Thie attached GIST is a package of Kubernetes yaml files and Java code to test locally with Docker/Kubernetes with the IBM FHIR Server.
You’ll want to kubectl apply -f <filename> for each of the files.
Then apply the fhir-server-config-snippet.json to your fhir-server-config.json
And run
kubectl config use-context docker-desktop
kubectl -n fhir-cicd-ns port-forward kafka-0 9092
