# Solr

Solr is highly reliable, scalable and fault tolerant, providing distributed indexing, replication and load-balanced querying, automated failover and recovery, centralized configuration and more. Solr powers the search and navigation features of many of the world's largest internet sites.

You can easily add it to your Lando app by adding an entry to the services top-level config in your Landofile.

# Patch versions

To use a patch version you can do something like this:

services:
  my-service:
    type: solr:5.5.5

But make sure you use one of the available patch tags for the underlying image we are using.

# Configuration

Here are the configuration options, set to the default values, for this service. If you are unsure about where this goes or what this means we highly recommend scanning the services documentation to get a good handle on how the magicks work.

Also note that the below options are in addition to the build steps and overrides that are available to every service.

services:
  my-service:
    type: solr:7
    portforward: false
    core: lando
    config:
      dir: SEE BELOW

# Portforwarding

portforward will allow you to access this service externally by giving you a port directly on your host's localhost. Note that portforward can be set to either true or a specific port but we highly recommend you set it to true unless you have pretty good knowledge of how port assignment works or you have a very compelling reason for needing a locked down port.

portforward: true will prevent inevitable port collisions and provide greater reliability and stability across Lando apps. That said, one downside of portforward: true is that Docker will assign a different port every time you restart your application. You can read more about accessing services externally over here.

tl;dr

Recommended

services:
  my-service:
    type: solr
    portforward: true

Not recommended

services:
  my-service:
    type: solr
    portforward: 8983

# Using a custom core

You can easily set up a different core name with the core cofig value

services:
  my-service:
    type: solr
    core: my-core

# Using custom solr config

You will almost certainly need to utilize your own custom Solr config. You can do that by telling Lando to inject solr config from a directory inside of your application.

Consider the below example of a Drupal 8 application injecting the Solr 7.x config directly from the search_api_solr module.

A hypothetical project

Note that you can put your configuration files anywhere inside your application directory. We use a config directory in the below example but you can call it whatever you want such as .lando.

./
|-- sites/all/modules/search_api_solr/solr-conf/7.x
   |-- elevate.xml
   |-- mapping-ISOLatin1Accent.txt
   |-- protwords.txt
   |-- schema_extra_fields.xml
   |-- schema_extra_types.xml
   |-- schema.xml
   |-- solrconfig_extra.xml
   |-- solrconfig_index.xml
   |-- solrconfig_spellcheck.xml
   |-- solrconfig.xml
   |-- solrcore.properties
   |-- stopwords.txt
   |-- synonyms.txt
|-- .lando.yml

Landofile's solr config

# Getting information

You can get connection and credential information about your solr instance by running lando info. It may also be worth checking out our accessing services externally guide.
