recently I've deployed demo environment with Business Central container (with http://aka.ms/getnav - as my favorite way). And found out that it doesn't have Cronus demo company. I've used microsoft/bcsandbox image, so it was W1 localization. As I understood - you get Cronus company only with US localization image (microsoft/bcsandbox:us).

Copy-FileFromNavContainer -containername navserver -containerpath c:/configurationpackages/NAV12.3.W1.ENU.extended.rapidstart -localpath C:\temp\NAV12.3.W1.ENU.extended.rapidstart
This way you'll get rapidstart package in your C:\temp folder:
After that - just import package and apply it:
We've got Cronus company with all demo data:
