Configure CiviCRM 5 with D8 using Lando

A better way to install CiviCRM on Drupal 8:

• Create a new Drupal 8 site with CiviCRM (replace 'some-dir' with the directory to create)
  composer create-project roundearth/drupal-civicrm-project:8.x-dev some-dir --no-interaction
• Adding CiviCRM to an existing Drupal 8 site :
  composer require civicrm/civicrm-asset-plugin civicrm/civicrm-drupal-8 civicrm/civicrm-packages
• Installing CiviCRM. 

Other old fashion approch, Get Drupal and install it

• Create a Drupal project
  composer create-project drupal-composer/drupal-project:8.x civicrm-drupal --stability dev --no-interaction
• Initialize Lando
  cd civicrm-drupal
  lando init --recipe drupal8 --webroot web
• Give your app the CiviCRMDrupal name then start Lando
  lando start
• Finally, install Drupal
  lando drush site-install standard --account-name=admin --account-pass=admin --db-url='mysql://drupal8:drupal8@database/drupal8' --site-name=CiviCRMDrupal

Get CiviCRM for Drupal 8

Run the following commands at the root of the civicrm-drupal directory

• Set CiviCRM version
  CIVICRM_VERSION=5.6.0
• Repositories aren't inherited from requirements, so we have to put this one from civicrm-core/composer.json again
  composer config repositories.zetacomponents-mail vcs https://github.com/civicrm/zetacomponents-mail.git
• Require civicrm-core at the requested version
  composer require "civicrm/civicrm-core:$CIVICRM_VERSION"
• Download the latest Drupal package to copy some stuff that's generated by the build and included in release tarballs.
  wget -O /tmp/civicrm.tar.gz https://download.civicrm.org/civicrm-$CIVICRM_VERSION-drupal.tar.gz
  tar -xzf /tmp/civicrm.tar.gz -C /tmp
• Copy the 3rd party dependencies. Should be done via Composer at a later stage
  cp -r /tmp/civicrm/packages vendor/civicrm/civicrm-core/
• Set up the civicrm-version.php
  cat /tmp/civicrm/civicrm-version.php | sed -e 's/Drupal/Drupal8/' > vendor/civicrm/civicrm-core/civicrm-version.php
• Copy SQL
  cp -r /tmp/civicrm/sql vendor/civicrm/civicrm-core/
• Copy some misc other things
  cp /tmp/civicrm/civicrm.config.php vendor/civicrm/civicrm-core/
  cp /tmp/civicrm/CRM/Core/I18n/SchemaStructure.php vendor/civicrm/civicrm-core/CRM/Core/I18n/
  cp /tmp/civicrm/install/langs.php vendor/civicrm/civicrm-core/install/
• Clean-up
  rm -rf /tmp/civicrm.tar.gz /tmp/civicrm

Get Drupal 8 CiviCRM module

• Get the module from GitHub. We will use the 5.7.x-dev that requires CiviCRM Core >=5.4.0
  composer config repositories.civicrm-drupal vcs https://github.com/civicrm/civicrm-drupal-8.git
  composer require civicrm/civicrm-drupal-8:5.7.x-dev

Install CiviCRM

• Go to /admin/modules and enable the CiviCRM Core module
• You will have this error while trying to access /civicrm in the browser
  Note: Sorry, due to an error, we are unable to fulfill your request at the moment.
  You may want to contact your administrator or service provider with more details about what action you were performing when this occurred.
  DB Constraint Violation - contact_id should possibly be marked as mandatory for DashboardContact, create API. If so, please raise a bug report.
  To get rid of it, go back to Drupal, logout and login again. See CRM-19878.

Allow CiviCRM to be accessed from the docroot

• CiviCRM will need to access its Javascript/CSS assets, so we will symlink the civicrm-core directory in the Drupal libraries directory.
  mkdir web/libraries (cd web/libraries/ && ln -s ../../vendor/civicrm/civicrm-core civicrm)
• Configure then the CiviCRM Resource URL at /civicrm/admin/setting/url?reset=1, set the following value:
  [cms.root]/libraries/civicrm/

Execute scheduled Jobs via the cron

• Install CV (the CiviCRM CLI) then execute this command via a system cron, in the docroot
  cv api Job.execute

Happy CiviCRM hacking!
