Edward Tan gave a great presentation (slides in vim!) on using puppet on FreeBSD. He introduced FreeBSD and showed us how puppet interacts with the system.

    PuppetCamp SEA 1 - Puppet & FreeBSD PuppetCamp SEA 1 - Puppet & FreeBSD Document Transcript

    • The Daemon in Puppets by Edward Tan (... next)1/25
    • Disclaimer I only represent myself and no one/company/entity else. I solemnly, sincerely and truly declare and affirm that I will tell the truth, the whole truth and nothing but the truth. (... next)2/25
    • Before Starting * How many of you heard about FreeBSD? * How many admins here? * BSD? * Linux? * Other unix? * windows??? :p gotta ask (... next)3/25
    • Whore you? * Blogger (psybermonkey.net & AboutBSD.net) * Author (BSDMag, second article coming out) * Speaker (of this talk, The Daemon in Puppets) (... next)4/25
    • What are you doing? * Full time System Administrator * network related * DNS * Radius * Apache * LDAP * Cacti * Nagios * -- snip -- (the list is getting too long) * shells * perl * bourne & again shell * Rest of the time * FreeBSD (... next)5/25
    • FreeBSD? Whats 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 (... next)6/25
    • * 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
    • * 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 (... next)8/25
    • Linus Torvalds once said : "If 386BSD had been available when I started on Linux, Linux would probably never had happened." (... next)9/25
    • Okay, why is there anything to do with Puppet? * Im 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 (... next)10/25
    • 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 * doesnt do templating & file line editing * e.g. file_line in stdlib (... next)11/25
    • * cssh * cool * reduced repetitious work across servers when deployment * but still back to square one when customizing servers (... next)12/25
    • * Bcfg2/etch * never like HTML (... next)13/25
    • * Chef * wolf in disguise * not free, at least for modules (... next)14/25
    • * cfEngine * looks promising * puppet just sound better (... next)15/25
    • 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)16/25
    • But I thought you mention Lazy, Impatience & Hubris? * Lazy * The manifest & modules needs to be setup once and can use many times * Impatience * Puppets 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 (... next)17/25
    • How do I install Puppet on FreeBSD? * use ports * it requires * ruby * portupgrade * others ... (... next)18/25
    • 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 (... next)19/25
    • (youre suppose to be showing off Puppet on FreeBSD) (... next)20/25
    • * conclusion after demo * for linux admin, puppet just works * for freebsd admin, puppet just works * for freebsd wannatry, puppet just works (... next)21/25
    • What I hope to see Puppet in FreeBSD * portmaster instead of portupgrade * new & shiny * patches are active * simple dependency, /bin/sh only (... next)22/25
    • Question? * Blog : http://psybermonkey.net * Email : edward@psybermonkey.net (... next)23/25
    • The End ... (... next)24/25
    • Errata * On slide 14, stating Chef is not Free wasnt true. This was a last minute learning that, there are open source Chefs modules which can be download and use freely. My mistake. Credits * History of FreeBSD - http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/history.html * Quote of Linus Torvalds - http://en.wikiquote.org/wiki/Linus_Torvalds * Quote "Lazy, Impatience & Hubris" was taken from Larry Wall, the creator of Perl - http://en.wikipedia.org/wiki/Larry_Wall The End, seriously this time. :)25/25
