DDEV Add-on Registry › ddev › ddev-drupal-solr

What is the difference between this and ddev-solr

Please consider using ddev/ddev-solr, which runs Solr in the modern “cloud” mode. This offers several advantages. If you are using Drupal, the biggest advantage is that you can update the Solr Configset from the UI or with a Drush command everytime you update search_api_solr.

The current addon runs in “classic standalone” mode. It is probably simpler at first to setup, but comes with the added maintainance steps for configsets. Most Solr hosting service providers run “Solr Cloud” as a backend.

What is this?

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

Installation on Drupal 9+

1. ddev add-on get ddev/ddev-drupal-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. Create a server with the following settings
   • Set “Server name” to anything you want. Maybe ddev-solr-server.
   • Set “Backend” to Solr
   • Configure Solr backend
     • Set “Solr Connector” to Standard
     • Set “Solr host” to solr
     • Set “solr core” to dev
     • Under “Advanced server configuration” set the “solr.install.dir” to /opt/solr.
6. ddev restart

Outdated Solr config files

If you get a message about Solr having outdated config files, you need to update the included Solr config files.

1. Click “Get config.zip” on the server page
2. Unzip the files, and put the config files into .ddev/solr/conf/
3. Run ddev restart

Explanation

This is the classic Drupal solr:8 image 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.

Alternate Core Name

If you want to use a core name other than the default “dev”, add a .ddev/docker-compose.solr-env.yaml with these contents, using the core name you want to use:

services:
  solr:
    environment:
    - SOLR_CORENAME=somecorename

1. Change SOLR_CORENAME environment variable in the environment: section.
2. Change your Drupal configuration to use the new core.

You can delete the “dev” core from http://<projectname>.ddev.site:8983/solr/#/~cores/dev by clicking “Unload”.

Caveats

• This recipe won’t work with versions of Solr before solr:8, and Acquia’s hosting requires Solr 7. You’ll want to see the contributed recipes for older versions of Solr.
