Drupal Lando configuration for Solr 8 and Search API

.lando.yml

name: drupal-solr
recipe: drupal8

config:
  # PHP 7 is required for Search API Solr > 2.
  php: '7.4'
  webroot: web

proxy:
  search:
    - admin.solr.lndo.site:8983

# Documentation    
# https://docs.lando.dev/config/solr.html
# https://docs.lando.dev/config/services.html
services:
  # Spin up a Solr container called "search".
  # Set "search" instead of "localhost"
  # on the Drupal search api solr server configuration.
  search:
    # Use a specific Solr version.
    type: solr:8
    # Optionally declare the name of the Solr core.
    # This setting is only applicable for versions 5.5 and above.
    core: drupal8
    portforward: true
    # This should be the directory containing the schema.xml and solrconfig.xml files.
    # Download the config.zip and extract it.
    config:
      conf: solr/conf

drupal8: org.apache.solr.common.SolrException:org.apache.solr.common.SolrException: Could not load conf for core drupal8: Can't load schema /opt/solr/server/solr/mycores/drupal8/conf/schema.xml: Plugin init failure for [schema.xml] fieldType "collated": Error loading class 'solr.ICUCollationField'

So we need to update the config file to $CORE/conf

• Download the latest config.zip
• lando ssh -s search
• cd /opt/solr/server/solr/mycores/drupal8
• replace conf with unzip config.zip -d $CORE/conf
• restart lando

One correction to above, run:
lando ssh -s search -u root

This way you don't run into permission issues

Also you do't really need to copy the config in that way. You can put it as a local folder in your setup say in config/solr, then in your lando.yml just do this:

services:
  search:
    type: solr:6.6
    portforward: true
    core: drupal8
    config:
      dir: config/solr

There are same update to do :

1- type: solr:7 instead of type: solr:7.1
2- conf: web/modules/contrib/search_api_solr/solr-conf-templates/7.x instead of 
    conf: web/modules/contrib/search_api_solr/solr-conf/7.x
