Drush Command for Installing core
I manage to install Drupal 8 with Drush after creating the project with Composer from drupal-composer/drupal-project. Steps I take are as follows:


Create project with dev dependencies:


composer create-project drupal-composer/drupal-project:8.x-dev directory-name --stability dev --no-interaction


Create site-database for the project.
Run inside web folder:


../vendor/bin/drush site:install standard --account-name=admin --account-pass=admin --db-url=mysql://username:password@localhost/site-database -y
