Support Drupal 9

[anavarre]

Currently, Lando doesn't seem to support Drupal 9.

$ lando init
? From where should we get your app's codebase? current working directory
? What recipe do you want to use?
backdrop
drupal6
drupal7
❯ drupal8
joomla
lamp
laravel

By default, we'd need support for PHP 7.3, MySQL 5.7 and Drush 10 to best support Drupal 9. See https://www.drupal.org/docs/9/how-drupal-9-is-made-and-what-is-included/environment-requirements-of-drupal-9

Cant we simply re-use the Drupal 8 template. Like a lot of modules are also just being updated in the .info file and not a whole new module/develop branch.

@BramDriesen yes we just need to update the versions as per OP.

D9 is D8 minus deprecated code + new versions of foreign dependencies, so nothing special here.

Install Drupal 9

// Create .lando.yml.
lando init --source cwd --webroot web --name drupal9 --recipe drupal8 --option php=7.3

// Start Lando.
lando start

// Create Composer project within drupal subfolder using Lando's Composer.
lando composer create-project drupal/recommended-project:^9@dev drupal
Do you want to remove the existing VCS (.git, .svn..) history? [Y,n]? y

// Move Drupal instance one level up.
mv drupal/* drupal/.* . && rm -rf drupal

// Add the latest Drush.
lando composer require drush/drush

// Install the demo_umami profile.
lando drush si demo_umami --db-url=mysql://drupal8:drupal8@database:3306/drupal8 -y

Drupal 9 site is now available at https://drupal9.lndo.site.

Plenty of choices are being made ATM, which will influence which LAMP stack will be able to run Drupal 9 sites. I mentioned https://www.drupal.org/docs/9/how-drupal-9-is-made-and-what-is-included/environment-requirements-of-drupal-9 above, but in more details I can think of the following at the very least:

• [policy] Decide on MySQL/MariaDB/Percona Server version support status for Drupal 9
• Raise the minimum MySQL version to 5.7 and MariaDB version to 10.2 in Drupal 9
• [policy] Decide on PostgreSQL 9.x/10.x support status
• Bump minimum PHP for Drupal 9 to PHP 7.3

So this means the Lando recipe that would work OOTB for D9 isn't going to be exactly the same as for D8. An alternative would be to bump the default PHP / MySQL version for D8, so we have only one recipe for both major versions.

Thanks @anavarre and @AaronFeledy for working on this. Drupal 9.0.0-beta1 was released today, and Drupal 9 is on track to be released on June 3 2020.
