Ensuring Drush commands run properly using Drush 8.x via Acquia Cloud Hooks

Any time there are major new versions of software, some of the tooling surrounding the software requires tweaks before everything works like it used to, or as it's documented. Since Drupal 8 and Drush 8 are both relatively young, I expect some growing pains here and there.

One problem I ran into lately was quite a head-scratcher: On Acquia Cloud, I had a cloud hook set up that was supposed to do the following after code deployments:

# Build a Drush alias (e.g. [subscription].[environment]).
drush_alias=${site}'.'${target_env}

# Run database updates.
drush @${drush_alias} updb -y

# Import configuration from code.
drush @${drush_alias} cim vcs

This code (well, with fra -y instead of cim) works fine for some Drupal 7 sites I work on in Acquia Cloud, but it seems that database updates were detected but never run, and configuration changes were detected but never made... it took a little time to see what was happening, but I eventually figured it out.

The tl;dr fix?

Highly available Drupal on a Raspberry Pi Cluster - phptek 2016 session

Raspberry Pi Dramble Cluster with Mini Raspberry Pi Zero Cluster

Another year, another field trip for the Pi Dramble—my 5-Raspberry-Pi cluster! I presented a session titled Highly available Drupal on a Raspberry Pi Cluster at php[tek] 2016, which just so happens to have moved to my hometown, St. Louis, MO this year!

For this presentation, I remembered to record the audio using a lav mic plugged into my iPhone, as well as iShowU to record what was on my screen. Sadly, I didn't have a secondary camera to capture the Pi Dramble itself, but you can glance at all the other 'Let's build a Pi Cluster' videos if you want to see it in action!

Here's a video recording of the presentation:

Drupal VM 3 is here!

Drupal VM 3.0.0 "The Light Sailer" was just released, and you can grab it from the Drupal VM website now. We spent a lot of time during DrupalCon New Orleans sprinting on Drupal VM, fixing bugs, and updating ALL THE THINGS to make sure this release solves a lot of pain points for individuals and teams who need a great local development environment.

Drupal VM - Website Homepage

Let's get right into why this is the best release of Drupal VM EVER!

The fastest and most modern environment

Drupal VM now defaults to Ubuntu 16.04 (which was just released in late April), running MySQL 5.7 and PHP 7. This means you're getting the fastest, most reliable, and most modern development environment for your Drupal 8 projects.

Adding a role to a user programmatically in Drupal 8

Since a quick Google search didn't bring up how to do this in Drupal 8 (there are dozens of posts on how to do it in Drupal 7), I thought I'd post a quick blog post on how you can modify a user's roles in Drupal 8. Hint: It's a lot easier than you'd think!

In Drupal 7, $user was an object... but it was more like an object that acted like a dumb storage container. You couldn't really do anything with it directly—instead, you had to stick it in functions (like user_multiple_role_edit()) to do things like add or remove roles or modify account information.

In Drupal 8, $user is a real, useful object. Want to modify the account name and save the change?

Thoughts on the Acquia Certified Developer - Drupal 8 Exam

Another year, another Acquia Certification exam...

Acquia Certified Developer - Drupal 8 Exam Badge 2016

I'm at DrupalCon New Orleans, the first North American DrupalCon since the release of Drupal 8. In addition, this is the first DrupalCon where the Acquia Certified Developer - Drupal 8 Exam is being offered, so I decided to swing by the certification center (it's on the 3rd floor of the convention center, in case you want to take any of the certification exams this week!) and take it.

Set up a faceted Apache Solr search page on Drupal 8 with Search API Solr and Facets

In Drupal 8, Search API Solr is the consolidated successor to both the Apache Solr Search and Search API Solr modules in Drupal 7. I thought I'd document the process of setting up the module on a Drupal 8 site, connecting to an Apache Solr search server, and configuring a search index and search results page with search facets, since the process has changed slightly from Drupal 7.

Install the Drupal modules

In Drupal 8, since Composer is now a de-facto standard for including external PHP libraries, the Search API Solr module doesn't actually include the Solarium code in the module's repository. So you can't just download the module off Drupal.org, drag it into your codebase, and enable it. You have to first ensure all the module's dependencies are installed via Composer. There are two ways that I recommend for doing this (both are documented in the module's issue: Keep Solarium managed via composer and improve documentation):

Migrate a custom JSON feed in Drupal 8 with Migrate Source JSON

Recently I needed to migrate a small set of content into a Drupal 8 site from a JSON feed, and since documentation for this particular scenario is slightly thin, I decided I'd post the entire process here.

I was given a JSON feed available over the public URL http://www.example.com/api/products.json which looked something like:

Drupal VM - DrupalEasy Podcast and DrupalCon NOLA BoF

As Drupal VM has passed 500 stars on GitHub, and is becoming a fairly mature environment for local development environment—especially for teams of Drupal developers who want to maintain consistency and flexibility when developing many sites, I've been working to get more stable releases, better documentation, and a more focused feature set.

Also, in the past few months, as interest has surged, I've even had the opportunity to talk about all things Drupal VM on the DrupalEasy podcast! Check out DrupalEasy Podcast 172 - The Coup (Jeff Geerling - Drupal VM), which was just posted a few days ago.

And to keep the conversation flowing, I'm going to be moderating a BoF on Drupal VM at DrupalCon New Orleans, Drupal VM and local Drupal development for teams.

Streaming PHP - disabling output buffering in PHP, Apache, Nginx, and Varnish

For the past few days, I've been diving deep into testing Drupal 8's experimental new BigPipe feature, which allows Drupal page requests for authenticated users to be streamed and loaded in stages—cached elements (usually the majority of a page) are loaded almost immediately, meaning the end user can interact with the main elements on the page very quickly, then other uncacheable elements are loaded in as Drupal is able to render them.

Here's a very quick demo of an extreme case, where a particular bit of content takes five seconds to load; BigPipe hugely improves the usability and perceived performance of the page by streaming the majority of the page content from cache immediately, then streaming the harder-to-generate parts as they become available (click to replay):
