Composer template for Drupal projects hosted on amazee.io

This project template should provide a kickstart for managing your site dependencies with Composer. It is based on the original Drupal Composer Template, but includes everything necessary to run on amazee.io (either the local development environment or on amazee.io servers.)

Requirements

• docker.
• pygmy gem install pygmy (you might need sudo for this depending on your ruby configuration)

Local environment setup

1. Checkout project repo and confirm the path is in docker's file sharing config - https://docs.docker.com/docker-for-mac/#file-sharing

git clone https://github.com/amazeeio/drupal-example.git drupal8-lagoon && cd $_

2. Make sure you don't have anything running on port 80 on the host machine (like a web server) then run pygmy up

3. Build and start the build images

docker-compose up -d
docker-compose exec cli composer install

4. Visit the new site @ http://drupal-example.docker.amazee.io

• If any steps fail you're safe to rerun from any point, starting again from the beginning will just reconfirm the changes.

What does the template do?

When installing the given composer.json some tasks are taken care of:

• Drupal will be installed in the web-directory.
• Autoloader is implemented to use the generated composer autoloader in vendor/autoload.php, instead of the one provided by Drupal (web/vendor/autoload.php).
• Modules (packages of type drupal-module) will be placed in web/modules/contrib/
• Themes (packages of type drupal-theme) will be placed in web/themes/contrib/
• Profiles (packages of type drupal-profile) will be placed in web/profiles/contrib/
• Creates the web/sites/default/files-directory.
• Latest version of drush is installed locally for use at vendor/bin/drush.
• Latest version of Drupal Console is installed locally for use at vendor/bin/drupal.

Updating Drupal Core

This project will attempt to keep all of your Drupal Core files up-to-date; the project drupal-composer/drupal-scaffold is used to ensure that your scaffold files are updated every time drupal/core is updated. If you customize any of the "scaffolding" files (commonly .htaccess), you may need to merge conflicts if any of your modified files are updated in a new release of Drupal core.

Follow the steps below to update your core files.

1. Run composer update drupal/core --with-dependencies to update Drupal Core and its dependencies.
2. Run git diff to determine if any of the scaffolding files have changed. Review the files for any changes and restore any customizations to .htaccess or robots.txt.
3. Commit everything all together in a single commit, so web will remain in sync with the core when checking out branches or running git bisect.
4. In the event that there are non-trivial conflicts in step 2, you may wish to perform these steps on a separate branch, and use git merge to combine the updated core files with your customized files. This facilitates the use of a three-way merge tool such as kdiff3. This setup is not necessary if your changes are simple; keeping all of your modifications at the beginning or end of the file is a good strategy to keep merges easy.

FAQ

Should I commit the contrib modules I download?

Composer recommends no. They provide argumentation against but also workarounds if a project decides to do it anyway.

Should I commit the scaffolding files?

The drupal-scaffold plugin can download the scaffold files (like index.php, update.php, …) to the web/ directory of your project. If you have not customized those files you could choose to not check them into your version control system (e.g. git). If that is the case for your project it might be convenient to automatically run the drupal-scaffold plugin after every install or update of your project. You can achieve that by registering @drupal-scaffold as a post-install and post-update command in your composer.json:

"scripts": {
    "drupal-scaffold": "DrupalComposer\\DrupalScaffold\\Plugin::scaffold",
    "post-install-cmd": [
        "@drupal-scaffold",
        "..."
    ],
    "post-update-cmd": [
        "@drupal-scaffold",
        "..."
    ]
},

How can I apply patches to downloaded modules?

If you need to apply patches (depending on the project being modified, a pull request is often a better solution), you can do so with the composer-patches plugin.

To add a patch to drupal module foobar insert the patches section in the extra section of composer.json:

"extra": {
    "patches": {
        "drupal/foobar": {
            "Patch description": "URL to patch"
        }
    }
}
