Puppet 3.x load balancer

[shell heriyanto]

Dear All,

I just plan want to migrate puppetmaster from 2.6 to puppet 3.0 in production, can you give me some advice about load balancer, because now im still using mongrel. Somebody have experience migrating puppet 2.6.x or 2.7.x to puppet 3.0.x on production?. Thanks.

Regards,

Heriyanto

The Pro Puppet book has a whole chapter on setting up Puppet with a load balancer. The information pertains to Puppet 2.6, 2.7, and 3.0. The only difference in 3.0 is the requirement to specify --confdir and --vardir in your rack up config file.

docs.puppetlabs.com should also have some information migrated from the redmine wiki.

HTH,
-Jeff

When you updated to Puppet 3.0, did you also modify your config.ru
file to include the new mandatory arguments of --confdir and --vardir?

An example config.ru is located at:
https://github.com/puppetlabs/puppet/blob/3.0.1/ext/rack/files/config.ru#L14-L18

Also, how did you upgrade to Puppet 3.0? Did you use OS native
packages, rubygem packages, or install.rb from source? (Or some other
installation method?)

Cheers,
-Jeff
