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 options, in addition to the build steps and overrides that are available to every service, are shown below:
services:
  myservice:
    type: solr:7
    portforward: false
    core: lando
    config:
      dir: SEE BELOWPort forwarding 
portforward will allow you to access this service externally by assigning 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:
  myservice:
    type: solr
    portforward: trueNot recommended
services:
  myservice:
    type: solr
    portforward: 8983Using a custom core 
You can easily set up a different core name with the core config value.
services:
  myservice:
    type: solr
    core: my-coreSolr 5+ only!
The core config value does not work for Solr 3.x or 4.x.
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 a Drupal 8 or 9 application injecting the Solr 7.x config directly from the search_api_solr module as shown in the example below:
A hypothetical project
Note that if using custom configuration you can put your configuration files anywhere inside your application directory. We use a config directory but you can call it whatever you want such as .lando. In this example we're using the "jump-start" configuration from search_api_solr:
./
|-- web/modules/contrib/search_api_solr/jump-start/solr7/config-set
   |-- 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
   |-- ... (and many more)

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.
