Always check your arguments

Quite a while back, RS wrote a comprehensive ansible role for handling Let's Encrypt certificate issuance and renewal. We both use this role extensively, which is why it was a significant issue when it suddenly started throwing type errors deep inside of the dnspython library during an nsupdate call in …

pre-commit and Pelican

Putting pre-commit to use I mentioned in a previous post about pre-commit, a tool for maintaining code consistency through simple management of pre-commit checks. The first place I decided to give this a whirl was on my blog sites. As you may be aware, I moved my blog sites (both …

pre-commit

Available as either a website with a very simple interface (and completion), or as a simple API-based service documentation for the API and …

Ansible become: useful and dangerous

OK, now that I have your attention with the catchy title, let me get right into the reason behind this post. Rob has been doing a lot of work lately on a set of roles to provision raspberry pi systems. I'm grateful for the work in this area, because frankly …

Separating Ansible roles for fun and profit

At ClueTrust, we use a lot of automation to run our systems. It's mostly how just a couple of us can manage hundreds of virtual servers and keep them up-to-date and operational. A few years back, I moved from using Puppet to Ansible, mostly at the suggestion of RS, who …
