If you are running this with Docker compose, you need to install the following:

If you are deploying to LKE(Linode Kubernetes Engine), you need to have the following setup:

If you are deploying to a local kubernetes cluster, you need to have the following setup:

Clone the repository by running the command git clone https://github.com/grpc-microservices
Run the command make compose to start up all the docker-compose services
Visit http://localhost:5000 in the browser to view the application. Currently, only 2 routes are available, /products to view product information from the database, and /videos to view video information from the database.
Finally stop the running services with CTRL + C and run docker-compose down to kill the containers.

Clone the repository by running the command git clone https://github.com/grpc-microservices
cd into the grpc-microservices directory
Run the command make k8s to package the helm chart and install the chart into your local minikube cluster.
Run the command kubectl get pods and wait till all the pods are in the Running state
Run the command minikube service grpc-app-svc to get a public ip you can use to view the application. Navigate to port 5000 to view the running application. Currently, only 2 routes are available, /products to view product information from the database, and /videos to view video information from the database.

Create a personal access token on your linode console
In the terraform directory, create a file called terraform.tfvars
Write linode_token = <your_linode_token> into the `terraform.tfvars file
Run the command make init to initialize terraform and run make up setup the linode cluster. On the liode console, make sure the nodes are provisioned before continuing
Run the command make kubeconfig to generate a kubeconfig file that allows you to run kubectl commands against the newly provisioned cluster.
Run the command make k8s to package the helm chart and install the chart into your local minikube cluster.
Run the command kubectl get pods and wait till all the pods are in the Running state
Run the command kubectl get svc grpc-app-svc and copy the external ip. Navigate to external-ip:5000 to view the running application. Currently, only 2 routes are available, /products to view product information from the database, and /videos to view video information from the database.
