I have federated by ArcGIS Server - Portal, and can add layers from the geodatabase as hosted layers in Portal when putting together a web map (under Add --> Search for Layers). However, I did publish a single layer as a feature service the other day and it automatically showed up in my "Contents" as a hosted layer. I have not been able to replicate that success though.
Now when I publish a map service it only shows up as a "Map Image Layer". In version 10.6 is this now synonymous with hosted "Feature Layer", or am I not doing something right? Is this because Portal will only recognize a feature service as a hosted layer, and not a map service?
How does one add a single layer as a "hosted feature layer" to Portal, and not a "Map Image Layer"?
