Deploying Nginx with Puppet - Pedro Pessoa http://www.serverdensity.com/puppetcamp/

1. Adding
Forge modules
to
Puppet Enterprise
http://www.rankpop.com/you-need-to-start-structuring-your-blog-posts-asap/

3. +15TB / mth
+1bn docs /mth
2-5k inserts/s @ 3ms
12K RPM @ 140ms

4. Servers
HTTP Load Balancer – 4x
Apache - 14x
Build - 2x
MongoDB - 20x data,
12x routing,
6x configuration,
1x arbiter,

5. HTTP Load Balancer
from Pound to nginx
New product : new load balancer
nginx :
- WebSockets
- SPDY standard
keep :
- manifests pulled from our Gihub repo by
the puppet master
- use of Puppet Console and Live Management
to trigger transient changes

6. Reinventing the wheel
(don't)
Writing our nginx manifest?
- add yet another one to the collection
community reach?
- whether our problem had already been solved
- or a kick start where we could stand on

9. Integration
A) get the actual code in
puppet module install puppetlabs/nginx
(or)
git submodule add https://github.com/puppetlabs/puppetlabs­nginx.git
B) run it on existing nodes
no parameterised classes on PE Console
(or)
merge our site.pp (which is empty) and the console,
it being an ENC and all - (how-merging-works)

10. Integration
Our solution
class serverdensity­nginx
{
class { 'nginx': }
nginx::resource::upstream {
'socky_rack':
ensure => present,
members => split( $lbTargetHostsSocky, ',' ),
}
(...)

11. nginx 'on-the-fly' update
class serverdensity­nginx
{
class { 'nginx': }
nginx::resource::upstream {
'socky_rack':
ensure => present,
members => split( $lbTargetHostsSocky, ',' ),
}
(...)

12. nginx 'on-the-fly' update

13. nginx 'on-the-fly' update

14. nginx 'on-the-fly' update

15. nginx 'on-the-fly' update

16. Alternatives
Puppet Labs nginx module:
https://github.com/serverdensity/puppetlabs-nginx
forked James Fryman's module:
https://github.com/jfryman/puppet-nginx
pick the later? Puppet Labs last update - 30th June
2011.
Forge namespace Puppet Labs (kick off early 2013?):
- best-in-class
- actively maintained
