## Application Architecture
## How to run the frontend application
Make sure you have the following installed on your machine:
- Node.js
- NPM
- Angular CLI
Run the following commands to start the frontend application
```shell
cd frontend
npm install
npm run start
```
## How to build the backend services
Run the following command to build and package the backend services into a docker container
```shell
mvn spring-boot:build-image -DdockerPassword=
```
The above command will build and package the services into a docker container and push it to your docker hub account.
## How to run the backend services
Make sure you have the following installed on your machine:
- Java 21
- Docker
- Kind Cluster - https://kind.sigs.k8s.io/docs/user/quick-start/#installation
### Start Kind Cluster
Run the k8s/kind/create-kind-cluster.sh script to create the kind Kubernetes cluster
```shell
./k8s/kind/create-kind-cluster.sh
```
This will create a kind cluster and pre-load all the required docker images into the cluster, this will save you time downloading the images when you deploy the application.
### Deploy the infrastructure
Run the k8s/manisfests/infrastructure.yaml file to deploy the infrastructure
```shell
kubectl apply -f k8s/manifests/infrastructure.yaml
```
### Deploy the services
Run the k8s/manifests/applications.yaml file to deploy the services
```shell
kubectl apply -f k8s/manifests/applications.yaml
```
### Access the API Gateway
To access the API Gateway, you need to port-forward the gateway service to your local machine
```shell
kubectl port-forward svc/gateway-service 9000:9000
```
### Access the Keycloak Admin Console
To access the Keycloak admin console, you need to port-forward the keycloak service to your local machine
```shell
kubectl port-forward svc/keycloak 8080:8080
```
### Access the Grafana Dashboards
To access the Grafana dashboards, you need to port-forward the grafana service to your local machine
```shell
kubectl port-forward svc/grafana 3000:3000
```
