About

This template builds Drupal 9 using the "Drupal Recommended" Composer project. It is pre-configured to use MariaDB and Redis for caching. The Drupal installer will skip asking for database credentials as they are already provided.

Drupal is a flexible and extensible PHP-based CMS framework.

Features

  • PHP 8.1
  • MariaDB 10.4
  • Redis 6
  • Drush included
  • Automatic TLS certificates
  • Composer-based build

Getting started

Deploy

Quickstart

The quickest way to deploy this template on Platform.sh is by clicking the button below. This will automatically create a new project and initialize the repository for you.

Deploy on Platform.sh


You can also quickly recreate this project locally with the following command:

composer create-project platformsh/drupal9 -s dev

Note:

Platform.sh templates prioritize upstream release versions over our own. Despite this, we update template dependencies on a scheduled basis independent of those upstreams. Because of this, template repos do not contain releases. This may change in the future, but until then the -s dev flag is necessary to use composer create-project.

Other deployment options

For all of the other options below, clone this repository first:

git clone https://github.com/platformsh-templates/drupal9

If you're trying to deploy from GitHub, you can generate a copy of this repository first in your own namespace by clicking the Use this template button at the top of this page.

Then you can clone a copy of it locally with git clone git@github.com:YOUR_NAMESPACE/drupal9.git.

Deploy directly to Platform.sh from the command line

Post-install

Run through the Drupal installer as normal. You will not be asked for database credentials as those are already provided.

Local development

This section provides instructions for running the drupal9 template locally, connected to a live database instance on an active Platform.sh environment.

In all cases for developing with Platform.sh, it's important to develop on an isolated environment - do not connect to data on your production environment when developing locally. Each of the options below assume that you have already deployed this template to Platform.sh, as well as the following starting commands:

$ platform get PROJECT_ID
$ cd project-name
$ platform environment:branch updates
Drupal: using ddev
For the most up-to-date instructions, please see our Using DDEV for local development guide in the Platform.sh Documentation.
Drupal: using Lando

Lando supports PHP applications configured to run on Platform.sh, and pulls from the same container registry Platform.sh uses on your remote environments during your local builds through its own recipe and plugin.

  1. Install Lando.
  2. Make sure Docker is already running - Lando will attempt to start Docker for you, but it's best to have it running in the background before beginning.
  3. Start your apps and services with the command lando start.
  4. To get up-to-date data from your Platform.sh environment (services and mounts), run the command lando pull.
  5. If at any time you have updated your Platform.sh configuration files, run the command lando rebuild.
  6. When you have finished with your work, run lando stop and lando poweroff.

Note:

For many of the steps above, you may need to include the CLI flags -p PROJECT_ID and -e ENVIRONMENT_ID if you are not in the project directory or if the environment is associated with an existing pull request.

Migrate

The steps below outline the important steps for migrating your application to Platform.sh - adding the required configuration files and dependencies, for example. Not every step will be applicable to each person's migration. These steps actually assume the earliest starting point possible - that there is no code at all locally, and that this template repository will be rebuilt completely from scratch.

If you already have code you'd like to migrate, feel free to focus on the steps most relevant to your application and skip the first section.

Getting started

Assuming that your starting point is no local code, the steps below will setup a starting repository we can begin to make changes to to rebuild this template and migrate to Platform.sh. If you already have a codebase you are trying to migrate, move onto the next step - Adding and updating files - and substitute any reference to the default branch main with some other branch name.

$ mkdir drupal9 && cd drupal9
$ git init
$ git remote add upstream https://github.com/drupal/recommended-project.git
$ git branch -m main
$ git fetch --all --depth=2
$ git fetch --all --tags
$ git merge --allow-unrelated-histories -X theirs 9.3.9

Adding and updating files

A small number of files need to be added to or modified in your repository at this point. Some of them explicitly configure how the application is built and deployed on Platform.sh, while others simply modify files you may already have locally, in which case you will need to replicate those changes.

Open the dropdown below to view all of the Added and Updated files you'll need to reproduce in your migration.

View files
File Purpose
config/sync/.gitkeep Added
web/sites/default/settings.php Updated:

The Drupal settings file has been updated to import and use web/sites/default/settings.platformsh.php.
web/sites/default/settings.platformsh.php Added:

Contains Platform.sh-specific configuration, namely setting up the database connection to the MariaDB service and caching via Redis.
.environment Added:

The .environment file is a convenient place to set environment variables relevant to your applications that may be dependent on the current environment. It is sourced before the start command is run, as the first step in the deploy and post_deploy hooks, and at the beginning of each session when you SSH into an application container. It is written in dash, so be aware of the differences to bash.

It can be used to set any environment variable, including ones that depend on Platform.sh-provided variables like PLATFORM_RELATIONSHIPS and PLATFORM_ROUTES, or to modify PATH. This file should not produce output.

Here, the Composer config and PATH are updated to allow executable app dependencies from Composer to be run from the path (i.e. drush).
.gitignore Added:

A .gitignore file is not included in the upstream, so one has been added.
.platform.app.yaml Added:

This file is required to define the build and deploy process for all application containers on Platform.sh. Within this file, the runtime version, relationships to service containers, and writable mounts are configured. It's also in this file that it is defined what dependencies are installed, when they are installed, and that package manager will be used to do so.

Take a look at the Application documentation for more details about configuration. For more information about the sequence of events that lead from a build to deployment, see the Build and deploy timeline documentation.

This template uses Composer 2 to install dependencies using the default composer build flavor prior to the build hook. Drush tasks are run during the deploy hook, and referenced again during the defined cron job.
drush/platformsh_generate_drush_yml.php Added:

This file has been included to generate the drush yaml configuration on every deployment.
.platform/services.yaml Added:

Platform.sh provides a number of on-demand managed services that can easily be added to your projects. It's within this file that each service's version, name, resources, and additional configuration are set. See the Services documentation for more details on configuration, version and service availability.

In this template, MariaDB and Redis have been configured.
.platform/routes.yaml Added:

This file is require to deploy on Platform.sh, as it defines how requests should be handled on the platform. It's within this file that redirects and basic caching can be configured. See the Routes documentation for more configuration details.
php.ini Added:

An initial php.ini file has also beed added. The settings are a result of performance testing and best practice recommendations coming from Blackfire.io. They will initialize Drupal with a number of good baseline performance settings for production applications, and complement many of the tests specified in .blackfire.yml.
.blackfire.yml Added:

This file has been added to help you get started using Blackfire.io on your project. See the Blackfire section below for more information on how to get started.
.lando.upstream.yml Added:

This file configures Lando as a local development option for this template. See the Platform.sh Lando plugin documentation for more information about configuration and the Local development section of this README for how to get started.
.ddev/providers/platform.yaml Added:

This file configures ddev as a local development option for this template. See the Platform.sh ddev integration documentation for more information about configuration and the Local development section of this README for how to get started. Be sure to follow the instructions provided through the ddev CLI and in the comments section of that file to correctly configure ddev for your project.

Dependencies and configuration

Sometimes it is necessary to install additional dependencies to and modify the configuration of an upstream project to deploy on Platform.sh. When it is, we do our best to keep these modifications to the minimum necessary. Run the commands below to reproduce the dependencies in this template.

$ composer require platformsh/config-reader drush/drush drupal/redis
$ composer config allow-plugins.composer/installers true --no-plugins
$ composer config allow-plugins.drupal/core-composer-scaffold true --no-plugins
$ composer config allow-plugins.drupal/core-project-message true --no-plugins
$ composer config allow-plugins.cweagans/composer-patches true --no-plugins

Migrating your data

If you are moving an existing site to Platform.sh, then in addition to code you also need to migrate your data. That means your database and your files.

Importing the database

First, obtain a database dump from your current site and save your dump file as database.sql. Then, import the database into your Platform.sh site using the CLI:

platform sql -e main < database.sql
Importing files

You first need to download your files from your current hosting environment. The easiest way is likely with rsync, but consult your old host's documentation.

The platform mount:upload command provides a straightforward way to upload an entire directory to your site at once to a mount defined in a .platform.app.yaml file. Under the hood, it uses an SSH tunnel and rsync, so it is as efficient as possible. (There is also a platform mount:download command you can use to download files later.) Run the following from your local Git repository root (modifying the --source path if needed and setting BRANCH_NAME to the branch you are using).

A few examples are listed below, but repeat for all directories that contain data you would like to migrate.

$ platform mount:upload -e main --mount web/sites/default/files --source ./web/sites/default/files
$ platform mount:upload -e main --mount private --source ./private

Note that rsync is picky about its trailing slashes, so be sure to include those.

Next steps

With your application now deployed on Platform.sh, things get more interesting. Run the command platform environment:branch new-feature for your project, or open a trivial pull request off of your current branch.

The resulting environment is an exact copy of production. It contains identical infrastructure to what's been defined in your configuration files, and even includes data copied from your production environment in its services. On this isolated environment, you're free to make any changes to your application you need to, and really test how they will behave on production.

After that, here are a collection of additional resources you might find interesting as you continue with your migration to Platform.sh:

Learn

Troubleshooting

Accessing logs

After the environment has finished its deployment, you can investigate issues that occured on startup, deploy and post_deploy hooks, and generally at runtime using the CLI. Run the command:

platform ssh

If you are running the command outside of a local copy of the project, you will need to include the -p (project) and/or -e (environment) flags as well. Once you have connected to the container, logs are available within /var/log/ for you to investigate.

Rebuilding cache

You may run into a database error after installing Drupal on your production environment initially. To fix, SSH into the application container (platform ssh) and rebuild the cache using Drush:

drush cache-rebuild
Default hash_salt behavior

Drupal's default settings set hash_salt to an empty string:

$settings['hash_salt'] = '';

In the past, Platform.sh templates have overridden this value:

$settings['hash_salt'] = $settings['hash_salt'] ?? $platformsh->projectEntropy;

This setting was insufficient to cover some user configurations - such as those cases when an application depends on a Null value for hash_salt.

Now, the setting looks like this in settings.platformsh.php:

$settings['hash_salt'] = empty($settings['hash_salt']) ? $platformsh->projectEntropy : $settings['hash_salt'];

This change sets hash_salt to the built-in environment variable PLATFORM_PROJECT_ENTROPY value if the project contains the default settings OR Null. If your application code depends on an empty value, feel free to comment out that line, or reset again later in that file.

Feel free to visit platformsh-templates/drupal9#73 for more details on this discussion.

Blackfire.io: creating a Continuous Observability Strategy

This template includes a starting .blackfire.yml file that can be used to enable Application Performance Monitoring, Profiling, Builds and Performance Testing on your project. Platform.sh comes with Blackfire pre-installed on application containers, and setting up requires minimal configuration.
