MongoDB Bangalore Workshop

How to get started with OpenShift and use it to deploy MongoDB application.

Transcript

1. 1 0 to AWESOME in Minutes with Red Hat's OpenShift and MongoDB Shekhar Gulati @shekhargulati OpenShift Evangelist, Red Hat
2. 2 Agenda • What is PaaS? • Let's become friends with OpenShift • What does development look like ? • Getting your hands dirty
3. 3 1) You know some MongoDB 2) You know some Java 3) You prefer to write code and apps over managing servers or you prefer managing servers rather than dealing with annoying developer requests Assumptions
4. 4 What is PaaS?
5. 5 Kind of like Amazon, right? Nope.
6. 6 Benefits of PaaS  Lets developer focus on his job i.e. to write code.  You develop “Cloud Aware” applications from the beginning.  Improves developer productivity.  Reduces cost and time to market.  Brings agility to product development.  Gives developers the power to prototype their ideas rapidly.
7. 7 Enter OpenShift
8. 8 Introducing OpenShift  A free auto-scaling, cloud-based application platform from Red Hat.  Multi Language, Multi Frameworks, Multi Cartridges.  No proprietary software.  No Lock-in.  Open source – OpenShift Origin.
9. 9 What’s supported?
10. 10 What else do I get and what is the catch?  OpenShift is free-as-in-beer & free-as-in-freedom  You get three free gears, each with 512MB memory and 1GB of disk space.  Need more resources, just ask!  The catch is we are in developer preview right now
11. 11 1. Deploying application on OpenShift using command line tools 2. Create a Wordpress app from the web console (if time permits) Note : The promo code is bangalore Demo
12. 12 Some terminology for today 1. Application – your web code and any data store. Has to be on 1 or more gears 2. Gear – is like a server. It can have only 1 language for the web programming. 3. Cartridge – it adds a language, a data store, or other functionality 4. Git – used for version control and managing code between server and your development machine 5. Ssh – command line tool to connect to your gear
13. 13 Let's get our hands dirty
14. 14 Create OpenShift Account https://openshift.redhat.com/app/account/new Promo code is bangalore
15. 15 Installing Client Tools Install Ruby 1.8.7 or greater Install Git Install rhc OpenShift gem Refer to documentation
16. 16 Setup your OpenShift Environment rhc setup -l <openshift_login>
17. 17 Let's take a look at GIT Distributed Version control A local repository – on your laptop A remote repository – on some other machine, usually a server
18. 18 You need to understand at least 3 commands in Git 1. Git add . (means add all new files as being tracked in the local repository) 2. Git commit –am “your message” (means commit all my changes to the local repository with this message) 3. Git push (means push from your local repository to the repository on your OpenShift gear)
19. 19 Creating an OpenShift Application rhc app create -a notebook -t jbossas-7 -d
20. 20 Adding MongoDB and RockMongo Cartridge rhc app cartridge add -a notebook -c mongodb-2.0 rhc app cartridge add -a notebook -c rockmongo-1.1
21. 21 Play with MongoDB running in the Cloud ssh into instance Type mongo on the shell Create a sample db Insert some documents in the collection Run some queries
22. 22 Pulling the code from GitHub git rm -rf src pom.xml git commit -am “removed default files” git remote add notebook -m master git://github.com/shekhargulati/notebook-part1.git git pull -s recursive -X theirs notebook master
23. 23 Let's look at the Code
24. 24 Deploy the application to OpenShift git push
25. 25 Play with the application Blog : http://red.ht/QmmaJ8
26. 26 1. OpenShift makes life great for you 2. The tools are easy to use 3. You should be ready to write services 4. Almost anything you need on a server 5. Did I mention – Free Conclusion
