Drupal 9 Apache Solr installation for DDEV

What is this?

This repository allows you to quickly install Apache Solr for Drupal 9 into a Ddev project using just ddev get drud/ddev-drupal9-solr. It follows the Setting up Solr (single core) - the classic way recipe.

Installation on Drupal 9

1. ddev get drud/ddev-drupal9-solr && ddev restart
2. You may need to install the relevant Drupal requirements: ddev composer require drush/drush:* drupal/search_api_solr
3. Enable the search_api_solr module either using the web interface or ddev drush en -y search_api_solr
4. Create a search_api server at admin/config/search/search-api -> "Add server"
5. Choose Solr as backend.
6. Choose "Standard" as the Solr connector type and configure it:
   • Set "Server name" to anything you want. Maybe "ddev-solr-server".
   • Set "Backend" to "Solr"
   • Set "Solr host" to solr.
   • Set "Solr core" name to "dev".
   • Under "Advanced server configuration" set the "solr.install.dir" to /opt/solr.
7. ddev restart

Explanation

This is the classic Drupal solr:8 recipe used for a long time by Drupal users and compatible with search_api_solr.

• It installs a .ddev/docker-compose.solr.yaml using the solr:8 docker image.
• A standard Drupal 9 solr configuration is included in .ddev/solr/conf.
• A .ddev/docker-entrypoint-initdb.d/solr-configupdate.sh is included and mounted into the solr container so that you can change solr config in .ddev/solr/conf with just a ddev restart.

Interacting with Apache Solr

• The Solr admin interface will be accessible at: http://<projectname>.ddev.site:8983/solr/ For example, if the project is named myproject the hostname will be: http://myproject.ddev.site:8983/solr/.
• To access the Solr container from inside the web container use: http://solr:8983/solr/
• A Solr core is automatically created by default with the name "dev"; it can be accessed (from inside the web container) at the URL: http://solr:8983/solr/dev or from the host at http://<projectname>.ddev.site:8983/solr/#/~cores/dev. You can obviously create other cores to meet your needs.

Caveats

• This recipe won't work with versions of solr before solr:8, and Acquia and Pantheon.io hosting require versions from 3 to 7. You'll want to see the contributed recipes for older versions of solr.
