.amazeeio.yml Example for Drupal 8 with Composer

We recommend using following the instructions here to create your drupal project using composer install, which automatically gives you the file below.

If Drupal 8 is installed via composer, composer is in charge of downloading Drupal Core, Drupal Contrib and external libraries. See the composer install command as a first command for development and production sites in order to make sure that everything is correctly installed.

Additionally the Drupal directory is usually installed within a subfolder of the Git repository. Therefore Drush and other Drupal related bash commands need to executed within that subfolder.

In this example, composer installs Drupal within a folder called web. See the cd web prefix for each command to ensure that drush is called in the right folder.

sitegroup: mysitegroup
deploy_tasks:
  development:
    before_deploy:
      - composer install
    after_deploy:
      - cd web && drush -y updb --cache-clear=0
      - cd web && drush -y cr
  production:
    before_deploy:
      - composer install
  after_deploy:
      - cd web && drush -y updb --cache-clear=0
      - cd web && drush -y cr
shared:
 production:
   - src: files
     dst: web/sites/default/files

Other important things to note:

• All drush commands are called with a -y, in order to ensure that no command is waiting for user input, which will not be possible during automated deployments.
• Additionally this -y is added right after the drush command, as in some situations (like drush rsync) drush would pass the -y to the subcommand (like rsync) instead of interpreting it itself.
• drush updb is called with the parameter --cache-clear=0 to ensure that there is no cache clear is called after the drush updb command has executed. This to prevent a double running of a cache clear in case that there was an update to apply. Also to ensure that we call a cache clear on every deployment, because just having drush updb as a command itself is not enough, as drush updb will only call a cache clear if there actually was an update to apply.
