This post provides the initial steps to get started on IBM's Bluemix. Bluemix is open-standard, cloud based Plat
Here are the steps to get going on Bluemix
First things first
I would suggest that you get all the registrations and installations right away.
Bluemix dashboard- Get started by creating an account on Bluemix. This will provide you access to the Bluemix's dashboard from which you can quickly create applications (mobile, Web, IoT, BigData) etc
Devops: Register for an account with Devops. Devops allows you to easily develop, deploy and track your code online. Devops also allows you to collaborate with others by forking code from their Git repositories
Cf Interface : Install the Command line interface 'cf'' to Bluemix. The 'cf' command interface is built with Google's Go programming language. With 'cf 'you can login to Bluemix, create an application, add services and manage your application. You can also do this from the Bluemix'es dashboard.
Install Git: There are multiple ways to develop code for Bluemix. Git command line happens to be one of them, So it makes sense to have this installed. You can install this from this link http
Install Node.js:The application that this post discusses is based on a Node.js based application so it will help to have it installed. Node.js is a platform that enables building of fast, scalable network applications and created by Ryan Dahl.
Kicking off Bluemix : A good first application to get moving on in Bluemix is the already available Sentiment Analysis of Twitter. This application uses the Node.js 'sentiment' module to perform some basic sentiment analysis.
The quickest and most painless way to get started on Bluemix is to 'fork' the code for Sentiment Analysis from Devops.
1) Login to your Devops account. Click the following Sentiments link from Devops, in which I have created a slight modification to the sentiment analysis application
2) Click the Edit Code button at the top. This will open the files and directories in this project (see picture below)
3) Next click the "Fork' button on the panel on the left side. This will create a copy of the above code in your own repository (see picture below )
4) The Twitter sentiment analysis code is in app.js written in Node.js. You can make changes to the code as needed. I have made a few modifications to the code that I had forked. I added changes which adds a textual output of the Twitter sentiment
How to make code changes with Web IDE
5) To make code changes double click the app.js file. This will open up the code window. You can use the GUI based IDE to make the code changes and merge with the master branch, The steps are
3. This will open a new window as shown below
4) Click the 'Stage to change' button.
5) This will move the changes to Staged. Click the 'Commit' button and enter the reason for the change and click the "Submit'
6) This will move the changes from 'Staged' to 'Commits for master branch'
7) Now click 'Push all' and click 'Ok' in the Git Push popup window. This will merge the changes into the master branch.
Code changes with Git command line
11) Incidentally the changes to code can also be made through the Git command shell as follows
a) git clone http
b) Modify the code using any editor and save the changes
c) Go the directory containing the files and do
git add *
d) git commit -m "Cosmetic" app.js
e) git push
This will push the changes to the git repository in the master branch
8) Click the 'Build & deploy' in the top right corner. You should see this
9) Click the 'Manage' button which will push the application onto the BlueMix
10) To test this application click the link next to 'Routes' . Enter a phrase that you would like to search and hit 'Go'
You should see the application checking Twitter periodically for the tweets.
Thats it! You have built your first Bluemix application.
The ability to integrate Node.js into your cloud application allows one to easily create powerful applications.
