I'd like to build a deployment of CM and Reporting in a single App Service. Is the best approach to take the XP0 files and try to remove what isn't needed ? Or try and combine The CM and Reporting from XP Scaled ? Is there any kind of walk through for this type of customization ?
Thanks
It depends a lot on expected load as to what the best scaling configuration is, but I will not go into that here.
To specifically answer your question, you can take the XP Scaled configuration and modify as follows:
infrastructure.json: remove resource sections for the Reporting Microsoft.Web/sites and Reporting Microsoft.Web/serverfarms and any references / dependencies to those resourcesapplication.json: remove the deployment of the Reporting site and any references / dependencies. It should still be setting the reporting DB connection string on your CM.Sitecore xxx (Cloud)_cm.scwdp.zip: alter the web.config <add key="role:define" value="ContentManagement,Reporting" />. Or ContentManagement,Reporting,Indexing if on 9.2+I would like to note though that it's possible Sitecore haven't tested this specific configuration before.
It's best to keep them separate azure web apps, but group CM and Reporting to the same app hosting plan. This way you don't have to regenerate the sitecore provided packages.
