README

Contains extensions, config etc. for a multidomain setup

Installation guide

1. Install iq_multidomain_extensions

2. add domain records /admin/config/domain

IMPORTANT NOTES

• Make sure that the pattern ids and template names have to be identical (Pay attention to - and _)

Upgrade from 2.x

With Drupal 10, domain_site_settings and domain_theme_switch are deprecated and are replaced by domain_config. This causes breaking changes.

• Upgrade to 2.5.y and run update hooks. This will convert favicons and robotstxt settings to use domain_config.
• Recreate theme selection per domain at /admin/appearance if iq_multidomain_domain_theme_switch was used before.
• Remove domain_site_settings and domain_theme_switch from the project
• Upgrade to 3.x

Theme per domain

Install the iq_multidomain_domain_theme_switch submodule:

drush en iq_multidomain_domain_theme_switch

Go to /admin/appearance to select the theme per domain.

Notes

• The sub module prefixes pattern ids from selected themes with the theme name (except for the global default theme).
• All themes need the same patterns to commonly use views.
• Autogenerated domain specific references to patterns might include the theme name and need to be adjusted on selecting or renaming a theme.

XML Sitemaps per domain

Install the iq_multidomain_sitemap_extension submodule:

drush en iq_multidomain_sitemap_extension

Go to /admin/config/search/xmlsitemap to add sitemaps. On each sitemap, there's a new field available to set the domain.

Favicon

The "iq_multidomain_favicon_extension" has been removed.

Robots.txt

If you want to register a robots.txt file per domain, you must activate iq_multidomain_robotstxt_extension. Install it with

drush en iq_multidomain_robotstxt_extension

Once installed, robots.txt can be configured at /admin/config/search/robotstxt.

Additionally incoming public requests have to be passed to the module (i.e. PHP) on either the /robots or /robots.txt path.

Kubernetes nginx ingress setup

You also need to add the following annotation to all main domain ingresses:

nginx.ingress.kubernetes.io/configuration-snippet: |-
  location = /robots.txt {
    rewrite ^ /robots last;
  }

It is also advised to enable the www-redirect option and to not set the www or non-www domain in the ingress respectively. (i.e. nginx.ingress.kubernetes.io/from-to-www-redirect: "true")

This rewrites incoming requests to robots.txt to the correct dynamic endpoint (/robots) bypassing any existing robots file.

Nginx example

If you want to pass the request to php directly in your application nginx, you can use an approach like this:

location = /robots.txt {
    rewrite ^ /index.php last;
}
