Installation

Instructions to install the Plate Recognizer SDK on your Kubernetes cluster.

  1. Contact support to enable Kubernetes for your account.
  2. Get helm from https://github.com/helm/helm/releases
  3. Setup your Kubernetes cluster. For example, https://kubernetes.io/docs/tasks/tools/install-minikube/
    • If using Minikube, make sure to enable the following addons dashboard ingress helm-tiller
  4. Clone this repository git clone https://github.com/parkpow/helm-charts.git and cd helm-charts
  5. Install the chart helm install platerec-sdk platerec-helm/ --set TOKEN=<MY_TOKEN> --set LICENSE_KEY=<LICENSE_KEY>

Configuration

  • To upgrade the chart, do helm upgrade platerec-sdk platerec-helm/ --set TOKEN=<MY_TOKEN> --set LICENSE_KEY=<LICENSE_KEY>
  • To delete the deployment, do helm delete platerec-sdk
  • To use the gpu version instead of the cpu version, do helm install platerec-sdk platerec-helm/ --set TOKEN=<MY_TOKEN> --set LICENSE_KEY=<LICENSE_KEY> --set image.repository=platerecognizer/alpr-gpu
  • To deploy to a different namespace other than default, include --namespace <namespace-name> to the install/upgrade command as so helm install platerec-sdk platerec-helm/ --namespace <namespace-name> --set TOKEN=<MY_TOKEN> --set LICENSE_KEY=<LICENSE_KEY>

Configurations variables that can be changed (by adding them to the install command using --set parameter)

Minikube Notes

To access the instance when using a custom cluster in Minikube, run the following command:

  • Simulate a load balancer minikube tunnel
  • Then run the commands shown after the helm install command.
  • You can also use this command to get the extenal_id kubectl get --namespace default svc -w platerec-sdk-test-platerec-helm
  • Finally call the SDK endpoint with curl -F 'upload=@/path/to/car.jpg' http://<external_ip>:8080/alpr
