k8s-fundamentals-basic-app's Introduction

k8s-fundamentals-basic-app

Description

This simple HTTP API was built for k8s training purposes. The API is available at the port 3000. You can use this to practice:

Liveness and Readiness

For Liveness: /health/live

This endpoint returns a simple JSON and 200 status if the app is started.

For Readiness: /health/ready

This endpoint will return 500 status if the database (configured in the config/db.js file) is not available and 200 status if the connection with the database was established.

To configure the database you can use the following env vars:

Variable Description
DB_HOST The address of the database
DB_USER The user to connect with the database
DB_PASSWORD The user password
DB_ACQUIRE_CONNECTION_TIMEOUT The timeout for acquiring a new connection
DB_POOL_SIZE The max number of connections
