Additional Service Configurations for ddev

DDEV-Local projects can be extended to provide additional services. This is achieved by adding docker-compose files to a project's .ddev directory that defines the added service(s). This page provides configurations for services that are ready to be added to your project with minimal setup.

If you need a service not provided here, see Defining an additional service with Docker Compose

Apache Solr

This recipe adds an Apache Solr container to a project. It will set up a solr core named "dev" with the solr configuration you define.

Installation

  1. Copy docker-compose.solr.yaml to the .ddev folder for your project.
  2. Create the folder path .ddev/solr/conf.
    • If needed, you may copy/extract the Solr configuration files for your project into .ddev/solr/conf. Ensure that the configuration files are present before running ddev start.
  3. Run ddev start or ddev restart if your project is already running.
Drupal8-specific extra steps
  • ddev start
  • Enable the Search API Solr Search Defaults module
  • Add a solr server at https://<projectname>>.ddev.site/en/admin/config/search/search-api/add-server.
    • Use the "standard" Solr connector
    • Use the "http" protocol
    • The "solr host" should be "solr" NOT the default "localhost"
    • The "solr core" should be named "dev" unless you customize the docker-compose.solr.yaml
    • Under "Advanced server configuration" set the "solr.install.dir" to /opt/solr
  • Download the config.zip provided on /admin/config/search/search-api/server/dev
  • Unzip the config.zip into .ddev/solr/conf. For example, cd .ddev/solr/conf && unzip ~/Downloads/solr_8.x-config.zip
  • In order for changes to take effect you must stop the project, remove the Solr volume, and start it again. So run docker volume rm ddev-<projectname>_solr if your project is called "myproject" then you would run ddev stop && docker volume rm ddev-myproject_solr && ddev restart. (If you have installed solr-configupdate.sh as described below, then you need only ddev restart)
Updating Apache Solr configuration on an existing Solr core

The default solr-precreate script provided in docker-solr and used in the entrypoint in docker-compose.solr.yaml does not have the capability to update core configuration after the core has been created. It just copies mounted config into the core, where it would otherwise live forever. However, a simple optional script executed on startup can re-copy config into place. Here's the technique:

  • Copy solr-configupdate.sh to .ddev/solr. This simple script is mounted into the container and updates config from .ddev/solr/conf on ddev restart: cd .ddev/solr && rm -rf solr-configupdate.sh && curl -O https://raw.githubusercontent.com/drud/ddev/master/pkg/servicetest/testdata/TestServices/solr-configupdate.sh && chmod +x solr-configupdate.sh
  • Make sure solr-configupdate.sh is executable: chmod +x .ddev/solr/solr-configupdate.sh
  • You can now copy/edit/update the solr configuration files for your project in .ddev/solr/conf and when you ddev restart the solr configuration will be live.
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 the web container use: http://solr:8983/solr/
  • A Solr core is automatically created 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.

Memcached

This recipe adds a Memcached 1.5 container to a project. The default configuration allocates 128 MB of RAM for the Memcached instance; to change that or other command line arguments, edit the command array within the docker-compose file.

Memcached Installation

Interacting with Memcached

  • The Memcached instance will listen on TCP port 11211 (the Memcached default).
  • Configure your application to access Memcached on the host:port memcached:11211.
  • To reach the Memcached admin interface, run ddev ssh to connect to the web container, then use nc or telnet to connect to the Memcached container on port 11211, i.e. nc memcached 11211. You can then run commands such as stats to see usage information.

Beanstalk (Work Queue)

This recipe adds a Beanstalk container to a project.

Beanstalk Installation

Interacting with the Beanstalk Queue

  • The Beanstalk instance will listen on TCP port 11300 (the beanstalkd default).
  • Configure your application to access Beanstalk on the host:port beanstalk:11300.
