Just to add to what @upforsin mentioned, there is the Alfresco Content Application (ACA), built using ADF, that is packaged as part of this docker installer. The ACA use case is for content users rather than Administrators, so there is not the same functionality as there is in Share. Nor is the Workflow functionality exposed, for example.
However, the ACA is extensible and the ADF has a number of "pre-built" components that you can "drop in" when developing your own UI on top of ACA.
