Every few weeks, when some of my automated Jenkins build jobs are running (using Ansible and my Jenkins role on Ansible Galaxy), they hit an error while configuring Jenkins plugins. The error is something like:

I use Ansible Vault to securely store the project's secrets (e.g. API keys, default passwords, private keys, etc.) in the git repository for many of my infrastructure projects. I also like to make sure I cover everything possible in automated tests/CI, using either Jenkins or Travis CI (usually).
But this presents a conundrum: if some of your variables are encrypted with an Ansible Vault secret/passphrase, and that secret should be itself store securely... how can you avoid storing it in your CI system, where you might not be able to guarantee it's security?
The method I usually use for this case is including the Vault-encrypted vars at playbook runtime, using
Besides being a software developer and photographer, I take a deep interest in spaceflight and love reading about the history and development of air- and spacecraft, with a special focus on early space program development.
A few books I've read in the past couple years have gone beyond being interesting just for their historic content—they gave me a lot of ideas to reflect on in relation to my approach to software development, especially what I'd term 'professional' software development (vs. hacking something together for fun, or churning out brochureware sites or cookie-cutter apps).
One book in particular, Failure is Not an Option (by Gene Kranz, famously known for his efforts as director of Mission Control during NASA's early days into the Apollo era), offered some great examples of how a high-performing team should operate, especially under pressure and with high stakes.
The St. Louis Drupal Users Group (STLDUG) just finished it's fourth Drupal Camp, held at UMSL yesterday. I had a great time meeting with everyone, and am excited for next year! Last year I had to miss the Camp due to unexpected surgery, but this year I was able to attend and even bring some of my photo gear, to take pictures (I love contributing to open source through means other than code!); here's the obligatory 'whole camp' photo:

I recently had to add support for the MaxMind free GeoIP database to a PHP container build that was based on the official Docker PHP image on Docker Hub. Unfortunately, it seems nobody else who's added this support has documented it, so I figured I'd post this so that the next poor soul who needs to implement the functionality doesn't have to spend half a day doing it!
First, you need the PHP
geoip extension, which is available via PECL (note: if you can make the PHP project itself use a composer library, there are a few better/more current geoip libraries available via Packagist!). Here's how to install it in one of the php 5.6 or 7.0-apache images (note that 7.1 uses Debian Stretch instead of Jessie... but the instructions should be the same there):
I maintain a lot of Ansible Galaxy roles. I probably have a problem, but I won't admit it, so I'll probably keep adding more roles :)
One thing I see quite often is someone submitting a simple Pull Request for one of my roles on GitHub, then checking in here and there asking if I have had a chance to merge it yet. I'm guessing people who end up doing this might not know about one of the best features of Ansible Galaxy (and more generally, open source!): you can fork the role and maintain your changes in the fork, and it's pretty easy to do.
I just had to do it for one project I'm working on. I am using the
rvm_io.ruby role to install specific versions of Ruby on some servers. But there seems to have been a breaking change to the upstream packages RVM uses, summarized in this GitHub issue. I found a pretty simple fix (removing one array item from a variable), and submitted this PR.
