Hot R.O.D. - Rides on Demand

This demo is based on the Jaeger HotROD demo but has been modified considerably to showcase Signadot & Sandboxes.

Running

First, install Signadot Operator if you haven't already.

Run everything in Kubernetes

Decide on a namespace in which to install HotROD and then run:

kubectl create ns "${NAMESPACE}"
kubectl -n "${NAMESPACE}" apply -k k8s/overlays/prod/<devmesh | istio>

To uninstall:

kubectl delete ns "${NAMESPACE}"

Development

Frontend

To run frontend you could easily run with air that helps with hot-reload.

Before running air or manual steps you have to set up the following env

export KAFKA_BROKER=kafka-headless.${NAMESPACE}.svc:9092
export REDIS_ADDR=redis.${NAMESPACE}.svc:6379
export FRONTEND_LOCATION_ADDR=location.${NAMESPACE}.svc:8081

Now let's run the frontend

air

That will listen for the changes and restart the server every change.

If no want to use this approach, you could

make build-frontend-app
go run ./cmd/hotrod/main.go frontend

Deployment

Release

To build and push new images, we can leverage by using the make release.

For the case of releasing latest images we can do RELEASE_TAG=latest make release. Note that you can replace the RELEASE_TAG with the value you need.

Considerations

You have to make sure you have the rights to write in signadot/hotrod.
