DevOps and Windows
- 2. Who am I? Left the corp world for a Solution/Service Provider in 2011 Prior to 2011, primarily focused on Windows and Citrix Now Linux, Chef, vCloud and Apace CloudStack/Citrix CloudPlatform as well as above. Prefer XenServer http://twitter.com/pigram86 http://www.todpigram.com http://github.com/pigram86
- 3. Windows automation Management in past were batch and command files along with Ghost an Ghost walker Altiris POSH System Center
- 5. My Task Find a tool to use with both Linux and Windows Needed to work with vCloud and CloudStack Provide Configuration Management and Desired State Config Be consistent and repeatable Be efficient and quick Puppet vs Chef - my choices
- 6. Challenges Part 1 Not a developer - I didn’t know Ruby I didn’t know anything about Puppet or Chef
- 7. Learning Went to www.codeacademy.com and took the Ruby portion Bought a Infinite Skills Ruby for Beginners course on www.udemy.com Sat through both Puppetlabs learning course and the learnchef.getchef.com training Built both the free open source version of Puppet Server and Chef Server in home lab Started coding with both on Windows as most of my customers are Windows based
- 8. My Dev Environment Macbook Pro 13” mid-2012 OS X 10.10 Chefdk git chruby with ruby-build - ruby 2.1.2/1.9.3 Vagrant, Veewee, Packer, Bento Berkshelf and Test-kitchen with kitchen-driver-vagrant_provision, foodcritic MDT server - for Autounattend.xml - both for builds and templates Virtualbox and VMware Fusion Sublime Text 3 with package control - Chef, DashDoc, Sublime-rubocop Dash
- 10. Chef and Windows • Chef provided cookbooks • chef_handler-1.16 • powershell-3.0.7 - pulls in ms_dotnet • windows-1.34.6
- 11. Using Chef with Windows • Reboots • Roles and Features • PageFile • Registry • Installing Software
- 12. Reboots • Both Puppet and Chef were working great until I started combining recipes/modules in a continuous run list. • Major issue…neither handled pending reboots
- 13. reboot_pending.rb • Alex Vinyar (Chef) provided me with a library file to handle pending reboots. This was added to Chef Client 11.12 • I still use it in all my cookbooks
- 15. Install Roles and Features • DISM - windows_feature • PowerShell - powershell_script • Caveat with PowerShell, if role/feature needs a reboot, you have to separate them
- 18. Windows Pagefile • Use Ohai to grab total memory • Differs between OS and Hypervisor • Differs between XenServer and vSphere • Differs between W2k8R2 and W2012/2012r2
- 19. Case Statement for Pagefile
- 20. Setting Pagefile - 4GB
- 21. Registry • using registry_key to set registry setting • Include recursive true • Use attributes for actual keys • use ‘/‘ or ‘' for ruby to recognize the path
- 22. Set registry settings Attribute Recipe
- 23. Installing Software • using windows_package • using batch and windows_zipfile • Installing standalone software • Installing software that requires the entire ISO • Always use not_if and only_if for idempotence • use attributes
- 24. Installing filezilla - Standalone
- 26. Testing For Linux - test kitchen For Windows mostly utilizing my home chef server and my custom windows boxes for Vagrant I use Veewee to create the VM, then export to .box. Chef-Client is installed as well as service.
- 27. Test to prevent this
