Use --drall-group=prod with only drush aliases files and no sites.*.php

[jameswilson]

Problem Statement

In a multisite Drupal 10 setup, when executing drall from a developer's local environment, I want a way to execute remote drush commands for all sites in a specific server environment via drush aliases *.sites.yml files.

Example Use Case

Get super user password reset links for all PROD sites.

drall --drall-group=prod exec drush uli

Expected Results

A list of password reset links for each domain grouped into the "prod" drall group via drush aliases *.sites.yml files.

Actual Results

Got error output:

In SitesFile.php line 37:

  Cannot read sites file: /var/www/html/docroot/sites/sites.prod.php

Steps to reproduce:

• Drupal 10 multisite.

• Drush aliases files for each site, each with entries for local, dev, test, and prod environments.

  drush/sites/site1.site.yml

  local:
    root: /var/www/html/docroot
    uri: https://site1.example.local
    paths:
      config-sync: /var/www/html/config/site1/sync
    drall:
      groups:
        - local
  dev:
    uri: https://www.dev.site1.example.com
    host: devserver.example.com
    user: username
    drall:
      groups:
        - dev
  test:
    uri: https://www.dev.site1.example.com
    host: testserver.example.com
    user: username
    drall:
      groups:
        - test
  prod:
    uri: https://www.dev.site1.example.com
    host: prodserver.example.com
    user: username
    drall:
      groups:
        - prod
  

• A single sites.php file with each domains pointing to its appropriate directory name.

  Note: It is critical to have all domains pertaining to a single site in one single file, as opposed to creating different files for each environment sites.local.php sites.dev.php sites.test.php sites.prod.php). Furthermore, we cannot depend on sites.prod.php because our PROD environment supports various subdomain clones like www.site1.example.com site1.oembed.example.com site1.example.com site1.com.

Proposed resolution

Before erroring out due to missing sites.GROUP_NAME.php file also scan all drush site aliases files containing drall groups defined that match the GROUP_NAME.
