The document discusses using Puppet to manage configurations across multiple FreeBSD servers. It begins with an introduction to FreeBSD and why the presenter chose to use Puppet. A demonstration is then provided showing how to install Puppet on FreeBSD and use it to configure Apache and other applications consistently across servers. The presentation concludes by noting how Puppet works well for both Linux and FreeBSD administrators.

3. Before Starting
* How many of you heard about FreeBSD?
* How many admins here?
* BSD?
* Linux?
* Other unix?
* windows???
:p gotta ask

* Radius
* Apache
* LDAP
* Cacti
* Nagios
* -- snip --
(the list is getting too long)

6. FreeBSD? What's that?
* Unix variant
* started from 386BSD, 1993
* advance, complex, sophisticated
* OS comes with :
* ZFS
* PF (packet filter)
* 10gbps
* IPv6 ready (since y2k)
* use by :
* companies
Apple
Cisco
Juniper
* web
Yahoo!
Apache
Netcraft

7. * a true operating system
* not just a kernel, but a base comes with it of tools & programs
* ports
* flexibility of source code
* simplicity of package management tools
* more then 23,000 applications waiting to be install by mere :
"make install"
(... next)
7/25

8. * and yet simple directory structured
* / root
* /dev device nodes
* /boot bootstrap needed programs & files
* /etc configurations
* /usr user land utilities & apps
* /usr/ports The FreeBSD ports collection
* /usr/local local executables & libraries
* /usr/local/share/doc documentations aka doc
* /var variable files
* /bin user utilities & apps
* /sbin system utilities & apps
* /mnt directory for mount points
* /tmp temporary directory
* these clearly defined directories eases organization of information
on the disk

9. Linus Torvalds once said :
"If 386BSD had been available when I started on Linux,
Linux would probably never had happened."

10. Okay, why is there anything to do with Puppet?
* I'm taking care of more then 60 servers
* 80% of it is FreeBSD
* new deployment & migration of these servers are happening
* new projects needs new services
* hardware refreshment & virtulization is moving these servers around
* disaster recovery
* automated
* redundancy
* automated setup of new server requires minimum documentation
* policies can be applied automatically
* ntpd
* sshd
* sudoers
* resolv.conf
* syslogd
* etc

11. Wow, you need to manage your configs more efficiently.
* Some alternative
* svn
* still required certain amount of work after svn export
* OS integration is minimum
* e.g.
create user
configure network card
static
* doesn't do templating & file line editing
* e.g. file_line in stdlib

12. * cssh
* cool
* reduced repetitious work across servers when deployment
* but still back to square one when customizing servers
(... next)

13. * Bcfg2/etch
* never like HTML
(... next)

14. * Chef
* wolf in disguise
* not free, at least for modules
(... next)
14/25

15. * cfEngine
* looks promising
* puppet just sound better
(... next)

16. Why Puppet?
* excellent documentation
* step by step guide
* tutorial with Virtual Machine provided
* surprisingly easy DSL
* client server model
* manages other platform also
* linux
* windows
* cisco?
* it works with FreeBSD
* system
* ports installation
* user creation
* service start/stop/restart
* file system
* file creation
* ownership
* available through ports
* cd /usr/ports/sysutils/puppet; make install
(... next)

17. But I thought you mention Lazy, Impatience & Hubris?
* Lazy
* The manifest & modules needs to be setup once and can use many times
* Impatience
* Puppet's excellent DSL & docs give gradual learning curve
* only learn what you need to know and implement
* Hubris
* Manifest & modules are the essence of using (showing off) Puppet

18. How do I install Puppet on FreeBSD?
* use ports
* it requires
* ruby
* portupgrade
* others ...
(... next)
18/25

19. Enough said, can you show me?
* expect these :
* "Puppetless" installation & configuration of FreeBSD
* apache22
* vhost
* test page
* Puppet master FreeBSD installation
* installation Puppet
* dependency installation
* Puppet master configuration
* client installation
* requirement installations
* first sign up of puppet with puppet master
* show off manifest of
* installation of ports
* user environment settings
* bash
* vim
* ssh
* tmux
* sudoers
* apache22
* vhost
* test page

21. * conclusion after demo
* for linux admin, puppet just works
* for freebsd admin, puppet just works
* for freebsd wannatry, puppet just works
(... next)
21/25

22. What I hope to see Puppet in FreeBSD
* portmaster instead of portupgrade
* new & shiny
* patches are active
* simple dependency, /bin/sh only

25. Errata
* On slide 14, stating Chef is not Free wasn't true. This was a last minute learning that,
there are open source Chef's modules which can be download and use freely. My mistake.
