Deploying Node JS Application on IBM Cloud

05 Jun 2019 » ibmcloud, nodejs

Purpose

  • Enable developer to develop & deploy Node JS application on IBM Cloud.
  • Enable developer to use IBM Cloud Cloudant NoSQL database service.
  • Enable developer to connect Cloudant NoSQL database service with existing deployed Node JS Application.

Pre-requistes

We will deploy a sample Node JS application on IBM Cloud that will store data in Cloudant NoSQL database.

Deploying sample Node JS starter application

Step 1 Select SDK for Node.js service

Select SDK for Node.js Service

Step 2 Provide unique name to application and then create application

Provide unique name to application followed by creating application

Step 3 Click on “Visit App URL” once application comes in awake state

Click on "Visit App URL" once application comes in awake state

Step 4 Verify application is up & running

Application starting page comes up

Running application locally

In previous section we have deployed a Node JS starter application to understand how to get started with application deployment on IBM Cloud. Now we will run a sample Node JS application on local machine.

Step 1 Clone GitHub repository containing source code of sample application

git clone https://github.com/IBM-Cloud/get-started-node

Step 2 Move into source code directory

cd ./get-starter-node

Step 3 Install dependencies

npm install

Step 4 Start application

npm start

Step 5 Open application in browser

Visit http://localhost:3000

Visit application

Deploying application on IBM Cloud

Deploying sample application that we have run locally in last section on IBM Cloud.

Step 1 Update manifest.yaml file with application name

---
applications:
 - name: <APP_NAME> // for e.g. indoredemo1   
   random-route: true
   memory: 256M

Step 2 Login into IBM Cloud Account

ibmcloud login --sso

Step 3 Set organization & space depending on the region where your application is deployed

ibmcloud target --cf

Step 4 Deploy application

ibmcloud cf push

Step 5 List deployed applications

ibmcloud cf apps

Creating Cloudant NoSQL database service

Step 1 Select database category

Select database category

Step 2 Select Cloudant database service

Select Cloudant database service

Step 3 Select authentication methods and then create a service

Select authentication methods

Connect Cloudant database service with deployed Node JS application

Step 1 Select created Cloudant database service

Select created Cloudant database service

Step 2 Select connections

Select connections

Step 3 Create a connection

Create a connection

Step 4 Select region and then connect the application

Select region & connect the application

Step 5 Restage application

Restage application Restage application

Note: Once connection is established between Cloudant database service & Node JS application then after restage database connection credentials are exposed as environment variables in the environment where Node JS application is deployed.

Verifying deployed application

Step 1 Go to Resource List

Go to deployed Node JS application service

Step 2 Select application

Select application

Step 3 Visit application URL

Select application

Step 4 Enter name

Enter name

Step 5 Verify name has been added in database

Verify name has been added in database

Conclusion

Both SDK for Node.js & Cloudant database service comes free with IBM Cloud Lite account with usage limitation, hence it can be used by the following:

  • Student who want to develop & deploy application on Cloud for internal/external project.
  • Student or Working Professionals who are planning a start up and want a platform where application can be developed & deployed with no cost and less time.
  • Working professional who wants to do some kind of POC or want to explore Cloud.
