This presentation is about marrying Windows and Linux together in a symphony of configuration and Lifecycle mangement.

7. CONFIGURATION & LIFECYCLE: MIXED ENVIRONMENTS
LINUX VS WINDOWS: SO DIFFERENT
▸ ls vs dir
▸ bash vs cmd
▸ cat vs type
▸ $PATH vs %PATH%
▸ /boot vs C:Windows
▸ ext4 vs NTFS
▸ apt-get vs ???

TOGETHER AS BROTHERS OR

CONFIGURATION & LIFECYCLE: MIXED ENVIRONMENTS 9

10. - CONFIGURATION MANAGEMENT
- LIFECYCLE MANAGEMENT
YES.
We just need something that would make sense for both worlds:

11. CONFIGURATION
MANAGEMENT
11

12. CONFIGURATION MANAGEMENT
WHEN IT IS MORE OF SPAGHETTI
▸ Scripts are hard to re-use
▸ High code duplication
▸ High entry point for new staff
▸ Low documentation quality
▸ No clear standards
▸ No business behind provision.sh
12

13. CONFIGURATION MANAGEMENT
BENEFITS OF CONFIGURATION MANAGEMENT
▸ Improved Efficiency (no more duplication and golden image maintenance. Almost like in Hollywood)
▸ Visibility
▸ Confidence (if a change is made it is made to a right range of systems)
▸ Auditability (source control and reports allow you to track all changes down)
▸ Predictability (rolling out a change is similar to a software release)
▸ Configuration Drift Remediation (two or more entities are identical)
▸ Living Documentation (configurations serve as a «source of truth» and are up-to-date)
▸ Captured Effort (two or more entities are identical)
13

14. CONFIGURATION MANAGEMENT
CROSS-PLATFORM
▸ Puppet
▸ Chef
▸ Ansible
▸ Salt
▸ CFEngine
WINDOWS PROPRIETARY
▸ PowerShell DSC
▸ SCCM
▸ WDS
▸ Dell KACE

15. CONFIGURATION MANAGEMENT
PUPPET: MULTI-PLATFORM SUPPORT
▸ Linux
▸ RHEL, Debian, Ubuntu, Fedora, SUSE, Gentoo, Arch
▸ BSD
▸ FreeBSD, OpenBSD
▸ Other Unix
▸ MacOS X, Solaris, AIX, HP-UX
▸ Microsoft Windows

17. CONFIGURATION MANAGEMENT
PUPPET: DEFINED STATE OF RESOURCES

19. CONFIGURATION MANAGEMENT
IIS CONFIG EXAMPLE
▸ Install IIS form scratch
▸ Site directory
▸ Hosts file entry
▸ IIS App Pool
▸ IIS Site
▸ IIS Application
▸ IIS Virtual Directory
▸ Includes SSL configuration

23. THIS?
HOW DO WE USE

24. LIFE CYCLE
MANAGEMENT

25. LIFECYCLE MANAGEMENT
CROSS-PLATFORM
▸ Puppet razor
▸ Chef knife-bootstrap
▸ Foreman (GUI, foreman-cli, REST)
WINDOWS PROPRIETARY
▸ SCCM
▸ WDS
▸ Dell KACE
25

26. LIFE CYCLE MANAGEMENT
Provisioning Configuration Monitoring
Provision on bare-metal
& public or private
clouds all from one
place with one simple
process.
A complete configuration
management solution
including an ENC for
Puppet and Salt, built-in
support for parameterized
classes and hierarchical
parameter storage.
Collect Puppet, Chef and
Salt reports and facts.
Monitor host
configuration, report
status, distribution and
trends.
THE FOREMAN
26

27. LIFE CYCLE MANAGEMENT
THE FOREMAN
▸ Platform agnostic provisioning
▸ CLI
▸ RBAC and LDAP integration
▸ Plugins
▸ API
▸ Audits
▸ Host groups
▸ ERB Templates
▸ PXEBoot, TFTP, Kickstart

36. WIMAGING
FOREMAN
36

37. LIFECYCLE MANAGEMENT
WIMAGING
▸ Linux style installation using http:// or ftp:// installation media
▸ No extra servers like WDS needed - all relevant settings can
be configured in Foreman directly
▸ Official Microsoft utilities are used for all relevant setup
stages making it easy to add (future) operating systems
▸ Driver installation during build time
▸ Support for localization settings (like time zone, locale, UI
language)
▸ Optional domain join including target OU
▸ Optional local user creation
▸ Support for Foreman's root password using Base64 encoding
▸ Correctly report finished host building
▸ Optional software installation and user tasks at the end of the
build (like installing puppet etc)
37

38. LIFECYCLE MANAGEMENT
WIMAGING: 10_INIT.CMD, CALLED FROM STARTNET.CMD
During WinPE boot
38

39. LIFECYCLE MANAGEMENT
WIMAGING FLOW
▸ Create host (user)
▸ Download bootfiles
▸ Boot to WinPE via wimboot
▸ Partition disk
▸ Apply image
▸ Add drivers
▸ User software (Puppet)
▸ Finish script
▸ Reboot
39

40. LIFECYCLE MANAGEMENT
WIMAGING SETUP
▸ Clone repo
▸ Setup Foreman & Templates
▸ Setup Medium
▸ Produce boot medium
▸ Produce install medium
▸ Sync medium to http/ftp
▸ Provision host
40

41. CONFIGURATION & LIFECYCLE: MIXED ENVIRONMENTS
WHAT DO WE GET
▸ Infrastructure as a code
▸ Platform-agnostic
▸ Reusable code & templates (Puppet, ERB) that make sense
▸ Single point of entry for DevOps, Developers, APIs
▸ As much Open Source as possible (presence +
contribution)
▸ Well supported (RedHat, PuppetLabs, Community)

43. MIXED ENVIRONMENT
OTHER THINGS THAT I SHOULD’VE MENTIONED
▸ Foreman supports Chef, Salt Ansible
▸ profile::nginx::www_site_com vs provision.sh
▸ Chocolatey supports private repositories
▸ Puppet can also operate in server-less mode
▸ IntelliJ IDEA or RubyMine support puppet DSL
▸ Logstash is awesome
