An example application of a scalable customer portal developed in Golang using gin for the backend and Angular for the frontend.
- Docker
- Protobuf and gRPC
- Kind
- Kubectl
- Helm
cd backend
./update-grpc.shAll microservices needs currently needs to be build manually. An example is shown how it works for subscription-service.
cd backend/subscription-service
docker build . --tag subscription-service
kind load docker-image subscription-service:latesthelm install customer-portal-test customer-portalCurrently, when deploying with kind the port is not exposed to the host, so you need to run an exposure command manually. You need to first find the name of the pod you want to expose.
kubectl get podsThen you can use the pod to expose the port.
kubectl port-forward robot-remote-controller-deployment-7b775fd47c-n9x59 8182:50051Note: exchange robot-remote-controller-deployment-7b775fd47c-n9x59 with
your pod.
The functionality that the system provides is viewing a camera on a remote device, e.g. a raspberry pi. Each customer has a subscriber account and they have a subscription to each of the cameras they want to view, i.e. one subscription for one camera. Both using the remote camera viewer and managing subscriptions is accessible through the customer portal.

An alternative to Golang for microservices is JAVA using the spring boot framework. However, it is slower and have become unessesaraly more complex over the year, and arguably Golang is more suited for microservices.
