Goals

1. Define "sidecar pattern"
2. Explain how to identify the sidecar pattern in a code repo

Kubernetes Demo

If you'd like to experiment with the sidecar pattern example, here's how:

1. Spin up a Kubernetes cluster

2. Create the sidecar-demo pod by running

    kubectl apply -f deployment.yaml
   

3. Port forward the node.js server with the command

    kubectl port-forward pod/<sidecar-demo-pod-name> 3000:3000
   

4. Use your browser or cURL to make a GET request to http://localhost:3000

5. Halt the port-forward process with ctrl + c

6. Look at the helper-app logs with the command

    kubectl logs <sidecar-demo-pod-name> -c helper-app
   

7. Pat yourself on the back for seeing how the sidecar pattern is implemented in Kubernetes!
