Puppet at SpaceX
How to stay sane, while sending rockets into space
Who’s this guy anyway?
 Linux system admin
 Came from the video game industry
 Started at SpaceX about 9 month ago
 Linux System Engineer
SpaceX
   Rocket Company
   First private company to send a vehicle to LEO
   AND recover the vehicle
   Founded in 2002
     Falcon1, Falcon 9, Dragon
Puppet

 How it happened
   Before Scale 10x
   After Scale 10x
Bootstrapping
 What we have
     Debian/Ubuntu
     Kerberos (windows KDC/Active Directory)
     LDAP (windows LDAP/Active Directory)
     “Apt” mirror (with debian squeeze/ubuntu LTS)
     Tons of scripts!
Deployment
 Using existing scripts and replacing them with puppet.
   Install packages from our local repo
   Push configs with puppet
   Using exec (in a couple of places only) to “fix” a couple of
     things.

 This simplified things a lot for us
Where are we at now?
 Plug desktop/server in (power/network/keyboard/video)
 Boot “off the network” (pxe)
 Pick on pxe menu what you want to install
     We have a number of “presets” we use
     Install starts and asks the user for hostname
     Machine uses a pre-seed file to setup stuff initially
     Installs puppet as part of that pre-seed from our local mirror
     Generate and registers with puppet server
     (login on server and sign cert)
     And wait for it! We’re DONE!
Cool stuff to come
 Puppet server infrastructure overview
   TheForeman
     Really nice and easy to setup
     Has “proxies” for handling stuff with DHCP/DNS/PXE
       automation (we’re planning on using this, and it’s a little more
       difficult for us, since that part of the infrastructure is windows
       based)
   Nagios monitoring
     Host lists/services/dependencies built by puppet
   HPC
     We have a compute cluster that we are starting to rebuild using
       puppet for automation and validation (test cluster with a couple
       of nodes, validate config, and push to production)

"Puppet at SpaceX" - Jok Thuau of SpaceX - PuppetCamp LA '12

  • 1. Puppet at SpaceX How to stay sane, while sending rockets into space
  • 2. Who’s this guy anyway?  Linux system admin  Came from the video game industry  Started at SpaceX about 9 month ago  Linux System Engineer
  • 3. SpaceX  Rocket Company  First private company to send a vehicle to LEO  AND recover the vehicle  Founded in 2002  Falcon1, Falcon 9, Dragon
  • 4. Puppet  How it happened  Before Scale 10x  After Scale 10x
  • 5. Bootstrapping  What we have  Debian/Ubuntu  Kerberos (windows KDC/Active Directory)  LDAP (windows LDAP/Active Directory)  “Apt” mirror (with debian squeeze/ubuntu LTS)  Tons of scripts!
  • 6. Deployment  Using existing scripts and replacing them with puppet.  Install packages from our local repo  Push configs with puppet  Using exec (in a couple of places only) to “fix” a couple of things.  This simplified things a lot for us
  • 7. Where are we at now?  Plug desktop/server in (power/network/keyboard/video)  Boot “off the network” (pxe)  Pick on pxe menu what you want to install  We have a number of “presets” we use  Install starts and asks the user for hostname  Machine uses a pre-seed file to setup stuff initially  Installs puppet as part of that pre-seed from our local mirror  Generate and registers with puppet server  (login on server and sign cert)  And wait for it! We’re DONE!
  • 8. Cool stuff to come  Puppet server infrastructure overview  TheForeman  Really nice and easy to setup  Has “proxies” for handling stuff with DHCP/DNS/PXE automation (we’re planning on using this, and it’s a little more difficult for us, since that part of the infrastructure is windows based)  Nagios monitoring  Host lists/services/dependencies built by puppet  HPC  We have a compute cluster that we are starting to rebuild using puppet for automation and validation (test cluster with a couple of nodes, validate config, and push to production)
