1 Provisioning MongoDB with Vagrant and Chef Nathen Harvey Web Opera=ons, CustomInk

2 CustomInk

3 My Work! Web Opera=ons at CustomInk! Automate! Support produc=on! Develop Rails! Monitor! Deploy! 20+ applica=ons in produc=on! Etc.

4 Outside of work! Coach Soccer for my kids! Enjoy going to concerts

5 How are your produc=on servers built?! git push heroku master! server.txt! Wiki page! Gold VM image / AMI! Infrastructure Automa=on framework! Chef! Puppet! Cfengine

6 Problem! Need to automate MongoDB server builds! Mul=ple mongo instances running on one host! Each mongo has unique configura=on sewngs

7 Developing a Solu=on! Build out VM using! Vagrant (for development purposes)! Chef

8 Vagrant! Tool for building and distribu=ng virtualized development environments! Uses Oracle s VirtualBox! h^p://vagrantup.com

9 Get Started with Vagrant! Install VirtualBox! Install Vagrant! gem install vagrant!! Create a VirtualBox image! vagrant box add lucid64 h^ps://github.com/mitchellh/vagrant/wiki/available- Vagrant- Boxes! h^p://

10 Get Started with Vagrant! Ini=alize the instance! vagrant init!! Creates the Vagranaile configures the VM! Start- up the VM! vagrant up!! Login! vagrant ssh!

11 Vagrant! Six steps to get a VM running with Vagrant:! Install VirtualBox! gem install vagrant!! vagrant box add <box name> <box URL>!! vagrant init <box name>!! vagrant up!! vagrant ssh!! Next, configure the server with Chef

12 Chef! Chef is an open source systems integra=on framework built to bring the benefits of configura=on management to your en=re infrastructure.

13 Chef Cookbooks! Cookbooks - encapsulate all the resources you need to automate your infrastructure and are easily sharable with other Chef users! h^p://cookbooks.opscode.com/! h^ps://github.com/opscode/cookbooks! h^ps://github.com/37signals/37s_cookbooks! h^ps://github.com/customink/cusotmink- cookbooks

14 Vagrant + Chef! Vagrant supports provisioning a VMs with:! Chef Solo! Chef Server! Puppet

15 PuWng it all together! Use Vagrant to launch a VM! Use Chef to provision MongoDB instances on the VM! Connect to the MongoDB instances on the VM

16 Code walkthrough! Next, we ll walk through the installa=on and configura=on process! 15 minutes to solu=on! With VirutalBox already installed

17 Install Vagrant

18 Add and Ini=alize the Box! We re using lucid64 box! Others are available! Create your own

19 Vagranaile

20 On to Chef! The base VM is ready to be launched! Next we ll move on to provisioning MongoDB with Chef

21 Set- up Chef Recipes! Clone the CustomInk Chef repo! Create some addi=onal directories! mkdir p cookbooks roles site- cookbooks/mongodb/recipes! Create a role file! Create a recipe for each MongoDB instance

22 Wait.what?! Let s define some of those chef terms! Recipe! fundamental configura=on unit in Chef! Install MongoDB, Install Apache, etc.! Cookbook! Fundamental distribu=on unit and include:! A^ributes, Recipes, Files, Templates, and more! Role! Group recipes and a^ributes! Applied to a node

23 Logger MongoDB! Recipe fundamental configura=on unit in Chef

24 Catalog MongoDB

25 Chef Role! Roles allow you to group recipes and a^ributes

26 Ready to launch! Chef configura=on is complete! We re now ready to launch the VM! First, we ll need to revisit the Vagranaile

27 Updated Vagranaile

28 Build and Provision the VM

29 Verify MongoDB

30 Connect to MongoDB

31 Solu=on! Use Vagrant + Chef to build and provision a local VM.

32 Quick Review! Install VirtualBox! gem install vagrant!! vagrant box add <box name> <box URL>!! vagrant init <box name>!! Clone chef repo! Add your own roles & recipes! Update Vagranaile! vagrant up!! vagrant ssh!

33 Developing Chef with Vagrant! Vagrant is a great way to test your Chef recipes! vagrant provision!! re- run recipes! Point your Vagranaile at a Chef server:

34 Chef is ready to cook MongoDB! Provision test and produc=on servers! Bootstrap using knife! Knife command line interface to chef! Assign the Run List! Assign using knife or the web UI! Ini=alize the replica set! Manual step at the moment! Should be built into the chef recipes

35 Cool, I m not using MongoDB! No worries I really want you to consider Vagrant and Chef! How to you get a new developer working with your app?! Include a Vagranaile in your repo! Provide access to your chef repo! Checkout and vagrant up! Other cool vagrant features

36 DC MongoDB Meet Ups! Meet third Wednesday of every month! Either in DC or at CustomInk in Tysons! Next Meet Up is next Wednesday! April 20 6:30 PM! Library of Congress

37 Upcoming Shows! Two great shows during Rails Conf! Sunday Funday at Pier 6! Bonnaroo Buzz at Rams Head Live

38 Thank You!! What ques=ons do you have? Nathen Harvey Web Opera=ons, CustomInk
