🚀 logger app

Contains 2 main services: One spams the other with messages while the other logs the messages it received.

🌐 First service: Logger

• Every time the route /ping is being called with an http post request, it adds a log of the message in the request body.
• Displays all the logs from its database.

💻 Second service: Pinger

• Pings the logger service and sends http post requests with a random message every 5 seconds to that /ping route.

🏁 Running the app (locally, using minikube and macOS)

1. Clone the repository:

git clone https://github.com/Robert076/logger.git

2. Start your local minikube server:

minikube start

3. Run the Kubernetes deployment:

kubectl apply -f kubernetes/

4. Port forward the logger port from inside the minikube

kubectl port-forward service/logger-service 8080:8080

5. Visit localhost:8080/pings on your browser.
