fruit-app-nodejs

Description

This is a Red Hat OpenShift Data Access demo that is built with Node JS to demonstrate the Service Binding feature that is available in OpenShift. The application is built with a set endpoints over REST. It's aalso a great way to find out how to avoid Scurvy.

What technology do we use?

• Node JS to build the REST endpoints
• Database (Mysql, or PostgreSql compatible DBs)
  • knex for DB migration
• Kube-service-bindings
• Compatible with RHODA/DBaaS platform

Prerequisites

• Docker
• Node.js
• OpenShift

build

# Build the app with Postgresql
$ docker build -f Dockerfile-pg -t quay.io/<quay_acct>/fruit-app-nodejs-pg:v0.0.1 .

# Build the app with MySQL
$ docker build -f Dockerfile-mysql -t quay.io/<quay_acct>/fruit-app-nodejs-mysql:v0.0.1 .

deploy to OpenShift

# update yaml files under k8s folder to reflect your image path

# Deploy the app with Postgresql
oc apply -f k8s/deploy-nodejs-pg.yaml

# Deploy the app with MySQL
oc apply -f k8s/deploy-nodejs-mysql.yaml

Commands to run locally:

• install all node components
• npm i
• start a PostgreSQL database system using docker images
• docker-compose up
• start up your server (should launch website)
• SERVICE_BINDING_ROOT=${local_binding_path}/bindings_local node [app_mysql.js|app_pg.js]
