@Dmitry Maslennikov

I join you in all these considerations:

  •  No lastest tag or 2021.1 sub-tag
    •  Corollary: Deleting versions without warning
  •  ARM64 images have separate names
  •  Health check behavior a bit weird
  •  Weak documentation of flags

For all these reasons I use the community versions for building my demos (thanks @Evgeny Shvarov).

However, for the problem of disappearing versions what we did with some customers is to copy the images in a private repository, it is not the most elegant solution but it works.

Another solution can be with SAM :

// Enable Intero metrics for SAM
zw ##class(Ens.Util.Statistics).EnableSAMForNamespace()
zw ##class(Ens.Util.Statistics).EnableSAMIncludeHostLabel()

Since the launch of IRIS, ENSDEMO namespace is gone.

Now to have demo or anything else you have to go with ZPM : https://community.intersystems.com/post/install-zpm-one-line (the package manager).

If you still want EnsDemo check those githubs :
