CI/CD with Drupal

Problem

  • CI/CD tools exist for the popular Drupal hosting platforms
  • Difficult to piece together incomplete tutorials from off the Drupal island
  • Need a practical guide to self-hosted Drupal CI/CD

Prerequisites

  • Drupal
  • Composer
  • Git
  • Behat
  • Command Line Bash
  • Docker
  • SSH
  • Private-Public Keys

CI/CD Process

<?php

/**
 * Say what's up to the world.
 */
class BlastIt {
  /**
   * Outputs a simple statement.
   */
  public function say_hello() {
    echo "hello, world";
  }
}

Code pushed to Gitlab

dev

stage

prod

Gitlab CI runs pipeline jobs on Gitlab runner

Gitlab runner spins up docker container to build, test, and deploy

Container connects to destination, fires deploy scripts

All jobs pass

What is an Artifact?

An artifact is one of many kinds of tangible by-products produced during the development of software.

- Wikipedia

Production is an Artifact of Development

Leave out dev dependencies, build files, config files, etc

Development

Artifact

section {
    height: 100px;
    width: 100px;

    .class-one {
        height: 50px;
        width: 50px;

        .button {
            color: #AF7AC5;

CI jobs produce Artifacts

A downloadable archive of the files at the end of a Job.

This is whatever you have told the job to produce.

An SSH task runner

Envoy

Uses Blade syntax to define tasks to be run on remote servers, such as

  • cloning your project from the repository,
  • installing the Composer dependencies,
  • and running Drush commands.

Deployment Strategies

  1. Build and rsync artifact container
  2. Commit to "artifact repo"
  3. Pull and build at destination
  4. Pull and build at symlink

Option 1:

Build and rsync artifact

No Example. Sorry.

Option 2:

Commit to "Artifact Repo"

Option 2: Commit to artifact repo

Provisioning Drupal

for Behat

Drupal CI Test Issues

# .gitlab-ci.yml

image: registry.gitlab.com/<USER>/my-project:latest

stages:
  - test

test:
  stage: test
  script:
    - phpunit  # note: drupal does not need to be provisioned
    - composer install
    # Provision Drupal via site-install or database backup
    - drush site:install  # or pg_restore . . .
    - drush config:import -y
    - php -S localhost:8080 -t ./web/ &
    - behat

Provisioning Options

  1. Restore a production database backup
  2. Run site install and config import

Option 1:

Restore a database backup

  • setup a cron job to pull a database backup to the runner server
  • setup a volume on the job's docker container

We need to get the backup to the runner job container

  • volumes are configurable at gitlab-runner
  • volumes are not accessible from jobs

Nope

  1. Push a container with all data pre-loaded
  2. Connect to remote database from job container

Possible work-arounds

Option 2:

Site install and config import

New in 8.6, install with existing config

$ drupal site:install --existing-config

In order to import config, the site UUID database must match configuration

Gotchas

  • Standard install profile
  • Override with Minimal
  • Force UUID to match
hook_install()

Fails if install profile implements

$ drupal site:install --existing-config
$ drush site:install minimal
$ drush config:import

Originally Standard, try to override install profile

Fails, can't override existing install profile.

Force UUID from config

# replace UUID
$ NEW_UUID=cat config/sync/system.site.yml | grep uuid | awk '{print $2}'
$ drush config:set -y system.site uuid $NEW_UUID

Shortcut Links already set

# Delete them
$ drupal entity:delete shortcut_set default

Could not delete

field body does not exist on entity type node. 

  • Do not re-add field_body field via UI
  • Must restore original configs for body field

Removed Body field, to implement Paragraphs

Tips

  • Try it locally first
  • Iterate locally if you can
docker run -it -v "$(PWD)":/var/www/html . . .
docker exec -it . . .
