devfile-sample's Introduction

nodejs-starter

This is a sample starter project that provides you with a basic Express app and a sample test in a /src/test sub directory. This sample project uses Express v4.17.x and enables health checking and application metrics out of the box. You can override or enhance the following endpoints by configuring your own health checks in your application.

Health checking

Health-checking enables the cloud platform to determine the readiness and liveness of your application.

These endpoints will be available for you to use:

Readiness endpoint: http://localhost:3000/ready
Liveness endpoint: http://localhost:3000/live

Application metrics

The prom-client module will collect a wide range of resource-centric (CPU, memory) and application-centric (HTTP request responsiveness) metrics from your application, and then expose them as multi-dimensional time-series data through an application endpoint for Prometheus to scrape and aggregate.

This endpoints will be available for you to use:

Metrics endpoint: http://localhost:3000/metrics

devfile-sample's Issues

Cannot open source in CodeReady

There seems to be an incompatibility with the current sandbox

Sample apps that use base image from Docker Hub might fail deployment due to pull rate limit

Currently, some (at least one - the nodeJS one ) built-in examples are using Docker.io. Users might hit Docker pull rate limit. Even if there is a workaround, it requires a Dockerhub account and some specific manipulations.
