Sitecore Roles PaaS Solr Connectivity

Here's a quick one for everyone.  I recently provisioned a full Sitecore XP 9.0.1 environment in Azure PaaS.  The only exception to this is a VM that is running Solr.  I was getting a lot of errors in Application Insights about xConnect not being able to connect to the Solr server.  I suspected that I was missing a hybrid connection somewhere, but wasn't sure which role was missing it.

I couldn't find a list from Sitecore's documentation of all the roles that need to access Solr.  I know that I could look for the "ContentSearch.Solr.ServiceBaseAddress" setting to find all references to my Solr server, so I downloaded all the config files from each Sitecore role and found the one I was missing (xConnect Search).  I added the hybrid connection to the Solr server to my xConnect Search App Service and was back to running with no exceptions again!

Note: The "ContentSearch.Solr.ServiceBaseAddress" setting was removed in Sitecore 9.0.2 and is now in the "" connection string.

For reference, here are the 5 roles that should be able to communicate with Solr:

  • Content Management
  • Content Delivery
  • Processing
  • Reporting
  • xConnect Search
