1. Create a simple project and Build&Deploy it. 2. Build&Deploy it again. 3. Pop-up with an option to specify Container Id and Alias shows up - see the attachment. The issue is that a user cannot specify container alias when the container is deployed for the first time. Let's say I am about to deploy version 2.0 of my project - I can specify container alias but there's no point to do it because users are already using the default alias which was specified with version 1.0 automatically by business central (by default it is container id without version I believe). I suppose that it should be possible for a user to define container id and alias even when the container is deployed for the first time - I can choose which alias I want so with future versions I can stick to it.
