Puppet Autosigning & Cloud Recommendations
I was over in Sydney this week attending linux.conf.au 2018 and made a short presentation at the Sysadmin miniconf regarding deploying Puppet in cloud environments. The majority of this talk covers the Puppet autosigning process which is a big potential … Continue reading

Puppet Training
I recently ran a training session for our development team at Fairfax introducing them to the fundamentals of Puppet. To assist with this training, I’ve developed a bunch of scripts and learning modules which I’ve now open sourced at https://github.com/jethrocarr/puppet-training Using … Continue reading

I’ve been continuing to migrate to my new server setup and Puppetising along the way, the outcome is yet more Puppet modules: The puppetlabs-firewall module performs very poorly with large rulesets, to work around this with my geoip/rirs module, I’ve … Continue reading

Puppet modules
I’m in the middle of doing a migration of my personal server infrastructure from a 2006-era colocation server onto modern cloud hosting providers. As part of this migration, I’m rebuilding everything properly using Puppet (use it heavily at work so it’s … Continue reading
Baking images with Packer & Pupistry
