helmfile-learning-prototype

The purpose of this project is to learn Helmfile.

Requirements

• Have 2 express services.
• Service proxy should proxy all requests to service main.

curl localhost:3000
{ url, body, query, headers, method }

• Both services should be running as Docker containers in a single Kubernetes Pod.
• The proxy service should be exposed using Kubernetes NodePort service.
• The project should be deployed to Minikube using Helmfile and a local Helm Chart.

Running locally

1. Install Docker, Minikube, and Kubectl and start Docker, and Minikube.
2. Start the project.

./bin/start.sh

3. Verify endpoints work correctly.

# Get the [PORT] from the output of ./bin/start.sh script.
# Proxied endpoint from proxy to main
curl http://127.0.0.1:[PORT]/proxy

# Endpoint on proxy not proxied to main
curl http://127.0.0.1:[PORT]/not-proxied

# Endpoint on main that should not be accessible
curl http://127.0.0.1:[PORT]/main

4. Uninstall the release shell
