drupal planet

Update: Since posting this, there have been some interesting new developments in this area, for example:

• There is now a Drupal/Kubernetes SIG which meets every other Wednesday.
• There are Kubernetes Drupal Operators which can manage Drupal instances in Kubernetes; I maintain the geerlingguy/drupal-operator but there are a couple others out there in development.

Since 2014, I've been working on various projects which containerized Drupal in a production environment. There have always been a few growing pains—there will for some time, as there are so few places actually using Docker or containers in a production environment (at least in a 'cloud native' way, without tons of volume mounts), though this is changing. It was slow at first, but it's becoming much more rapid.

It's been five years since Drupal VM's first release, and to celebrate, it's time to release Drupal VM 5.0 "Flynn Lives"! This update is not a major architectural shift, but instead, a new major version that updates many defaults to use the latest versions of the base VM OS and application software. Some of the new default versions include:

• Ubuntu 18.04 'Bionic' LTS (was Ubuntu 16.04)
• PHP 7.2 (was PHP 7.1)
• Node.js 10.x (was Node.js 6.x)

See the full release notes here: Drupal VM 5.0.0 "Flynn Lives"

There are also a number of other small improvements (as always), and ever-increasing test coverage for all the Ansible roles that power Drupal VM. And in the Drupal VM 4.x release lifecycle, a new official pre-baked Drupal VM base box was added, the geerlingguy/drupal-vm Vagrant base box. Using that base box can speed up new VM builds by 50% or more!

Thoughts about Drupal 8, Drupal 7, Backdrop, the Drupal Community, DrupalCon's meteoric price increases, DrupalCamps, and the future of the framework/CMS/enterprise experience engine that is Drupal have been bubbling up in the back of my mind for, well, years now.

I am almost always an optimist about the future, and Drupal 8 promised (and usually delivered) on many things:

• Vastly improved content administration
• Views in core, and even better than ever
• Media in core
• Layouts in core
• Modern programming paradigms (fewer #DrupalWTFs)
• 'Getting off the island' and becoming more of a normal PHP application (kinda the opposite of something like Wordpress)

But one thing that has always been annoying, and now is probably to the state of alarming, for some, is the fact that Drupal 8 adoption has still not hit a level of growth which will put it ahead of Drupal 7 adoption any time soon.

Update: The results are available for viewing in our presentation slides: download the 2019 Drupal Local Development presentation (PDF). There is also a video of the survey results presentation from DrupalCon Seattle.

It's that time of year again! Leading up to DrupalCon Seattle, Chris Urban and I are working on a presentation on Local Development environments for Drupal, and we have just opened up the 2019 Drupal Local Development Survey.

tl;dr: See the video below for a run-through of my process upgrading Drupal core on the real-world open source Drupal 8 site codebase Drupal Example for Kubernetes.

Over the years, as Drupal has evolved, the upgrade process has become a bit more involved; as with most web applications, Drupal's increasing complexity extends to deployment, and whether you end up running Drupal on a VPS, a bare metal server, in Docker containers, or in a Kubernetes cluster, you should formalize an update process to make sure upgrades are as close to non-events as possible.

From time to time, I have the need to take a Twig template and a set of variables, render the template, replacing all the variables within, and then get the output as a string. For example, if I want to have a really simple email template in a custom module which has a variable for first_name, so I can customize the email before sending it via Drupal or PHP, I could do the following in Drupal 7:

I've been going kind of crazy covering a particular Drupal site I'm building in Behat tests—testing every bit of core functionality on the site. In this particular case, a feature I'm testing allows users to upload arbitrary files to an SFTP server, then Drupal shows those filenames in a streamlined UI.

I needed to be able to test the user action of "I'm a user, I upload a file to this directory, then I see the file listed in a certain place on the site."

These files are not managed by Drupal (e.g. they're not file field uploads), but if they were, I'd invest some time in resolving this issue in the drupalextension project: "When I attach the file" and Drupal temporary files.

Since they are just random files dropped on the filesystem, I needed to:

tl;dr: Run composer require zaporylie/composer-drupal-optimizations:^1.0 in your Drupal codebase to halve Composer's RAM usage and make operations like require and update 3-4x faster.

A few weeks ago, I noticed Drupal VM's PHP 5.6 automated test suite started failing on the step that runs composer require drupal/drush. (PSA: PHP 5.6 is officially dead. Don't use it anymore. If you're still using it, upgrade to a supported version ASAP!). This was the error message I was getting from Travis CI:

I ran the test suite locally, and didn't have the same issue (locally I have PHP's CLI memory limit set to -1 so it never runs out of RAM unless I do insane-crazy things.

Wait... what? If you're reading the title of this post, and are familiar with Acquia BLT, you might be wondering:

• Why are you using Acquia BLT with a project that's not running in Acquia Cloud?
• You can deploy a project built with Acquia BLT to Kubernetes?
• Don't you, like, have to use Docker instead of Drupal VM? And aren't you [Jeff Geerling] the maintainer of Drupal VM?

Well, the answers are pretty simple:

Earlier this year, I completely revamped Hosted Apache Solr's architecture, making it more resilient, more scalable, and better able to support having different Solr versions and configurations per customer.

Today I'm happy to officially announce support for Solr 7.x (in addition to 4.x). This means that no matter what version of Drupal you're on (6, 7, or 8), and no matter what Solr module/version you use (Apache Solr Search or Search API Solr 1.x or 2.x branches), Hosted Apache Solr is optimized for your Drupal search!
