# Vehicle Tracker Dapr
A sample shipment tracker to showcase Dapr components and features.
## Architecture and Service Definitions
## Demo setup
## Prerequisites
- Kubernetes cluster of your choice (3+ nodes recommended)
- Helm
## Clone this repository
```git
git clone https://github.com/rochabr/vehicle-tracker-dapr.git
cd vehicle-tracker-dapr
```
## Create application namespaces
After connecting to your cluster, run the following command to create the namespaces:
```bash
# create application namespaces
kubectl create ns vehicle-tracker # vehicle teracker namespace
kubectl create ns dapr-system # Dapr
kubectl create ns redis # Redis
kubectl create ns kafka # Kafka
kubectl create ns zipkin # Zipkin
```
## Install Dapr and create RBAC
You can choose to skip this step if you want Conductor to manage your Dapr installation (recommended):
```bash
dapr init -k -n dapr-system
kubectl apply -f ./components/minikube/dapr-secret-reader.yaml
```
## Setup Helm
```bash
helm repo add bitnami https://charts.bitnami.com/bitnami
helm repo update
```
## Redis setup
Install Redis, export the password and create a secret that will be accessed from the component files.
```bash
helm install redis bitnami/redis -n redis
export REDIS_PASSWORD=$(kubectl get secret --namespace redis redis -o jsonpath="{.data.redis-password}" | base64 -d)
kubectl create secret generic redis-password --from-literal=redis-password=$REDIS_PASSWORD -n vehicle-tracker
```
## Kafka setup
Install Kafka, export the password and create a secret that will be accessed from the component files.
```bash
helm install --set persistence.enabled=false --set zookeeper.persistence.enabled=false --set auth.clientProtocol=sasl kafka bitnami/kafka -n kafka
export KAFKA_PASSWORD=$(kubectl get secret kafka-user-passwords --namespace kafka -o jsonpath='{.data.client-passwords}' | base64 -d | cut -d , -f 1)
kubectl create secret generic kafka-password --from-literal=kafka-password=$KAFKA_PASSWORD -n vehicle-tracker
```
## Install Zipkin
Zipkin will be used for applicaiton tracing.
```bash
echo "Zipkin namespace created"
kubectl create deployment zipkin -n zipkin --image openzipkin/zipkin
echo "Zipkin deployment created"
kubectl expose deployment zipkin -n zipkin --type LoadBalancer --port 9411
echo "Zipkin deployment exposed"
kubectl get svc -n zipkin -w
export ZIPKIN_DASHBOARD=$(kubectl get svc --namespace zipkin zipkin -o jsonpath="{.status.loadBalancer.ingress[0].ip}"):9411
echo "View tracing dashboard at $ZIPKIN_DASHBOARD"
```
## Deploy Dapr components
Now we will deploy the components that we will use throughout the demo:
```bash
kubectl apply -f ./components/minikube
```
## Deploy services
```bash
kubectl apply -f ./deployment/services
```
> The contents of the folder `/deployment-files/k8s` are used for automated CI/CD pipelines, as described in the main [README](./../README.md) file.
Check the state of your pods by running:
```bash
kubectl get pods -n vehicle-tracker
```
## Expose the service on MiniKube
```bash
minikube service shipment-handler --url -n vehicle-tracker
```
