Drupal with GitLab Auto DevOps

This project is a boilerplate to use Drupal with GitLab Auto DevOps
features.

Context

This project:

• Use Docker, cross-platform (including docker-toolbox)
• Doesn't use Drupal docker image
• Is a "click & deploy" project
• Is easy to maintain
• Use custom Helm/Kubernetes chart, so it's highly customizable
• Provide both production and development environments
• Use webflo/drupal-core-require-dev

Online installation

• Fork this project (on any gitlab instance)
• On the sidebar, click Operations > Kubernetes
• Add a Kubernetes cluster (GKE recommended)
• Once the cluster is ready, at least install
  • Helm
  • Ingress
  • GitLab-runner
• Once Ingress install is done, you'll be able to retrieve Ingress Endpoint (on the
  same page)
  • You'll have to fill the base domain (top page) with:
  • YOUR_INGRESS_IP.nip.io or
  • Use YOUR_INGRESS_IP to add an "A" record DNS with your domain
    (*.your_domain.com) then add your_domain.com as base domain.
• On the sidebar, click Settings > CI / CD
• Expand "Variables"
• At least, add the next variables:

  • Name	Description	Default value
    DB_INITIALIZE	In one line, the command to be used to initialize the website.	bash /var/www/html/scripts/db-initialize.sh
    DB_MIGRATE	In one line, the command to be used on each website's upgrade.	bash /var/www/html/scripts/db-migrate.sh
    K8S_SECRET_POSTGRES_SALT	The drupal's database salt.	whateverYouWantAsDBSalt
    TEST_DISABLED	GitLab Auto DevOps test jobs aren't used by default.	true

  • Save variables
• Expand "Auto DevOps"
• Enable Default to Auto DevOps pipeline
• Choose your deployment strategy
• Save changes, enjoy =)

Local installation

Linux: using bash
Windows: using docker shell (or docker-toolbox)

Install dependencies

$ docker run --rm --interactive --tty --volume
${PWD}:/app composer install --ignore-platform-reqs

Build

$ docker-compose -f ${PWD}/docker-compose.yml build

Start

$ docker-compose -f ${PWD}/docker-compose.yml up -d
$ docker exec -it autodevopsdrupal_web_1 chmod 555 /var/www/html/web/sites/default/settings.php

Then go to http://${DOCKER_IP}:5000/ to get Drupal's installation
page, or...

Initialize through CLI.

After starting the container, execute

$ docker exec -it autodevopsdrupal_web_1 bash /var/www/html/scripts/db-initialize.sh

This is a simple shell-script which use drush to instantiate the database.

Access website

Go to http://${DOCKER_IP}:5000/user/login, default authentication
is admin:admin.

Enjoy =)

Online environment architecture

The chart used is coming from the default one used by Auto DevOps, so we have
2 main pods:

• One for the database (postgres)
• One for the app (php:7.2-apache-stretch)

Known issues

As the chart uses basic google persistent volumes, the only access mode
available is ReadWriteOnce, therefore we can't have multiple app replicas.
This means the scalability of this project is not perfect for now. You can still upgrade to a better cluster/node.
