Andrew, thanks a bunch for pointing people to our org! I really appreciate it.

I have run AD DC successfully in docker (with and without docker-compose), 
podman and kubernetes. However, my main use case for the Samba AD DC is 
testing our file-server oriented projects. I personally do not know if anyone's 
running the AD DC image our samba-containers projects builds as a production 
server.

I know there would be stumbling blocks around the workflow adding multiple DCs 
right now. It's not insurmountable but it's not something I or any of my 
teammates have had time to work on. Our main focus has been on file server stuff 
especially ramping up testing with clustered file systems backends. There's 
many things I'd like to do with the AD DC image but I don't find the time.

(PS. I'm not familiar with `secret sausage` do you mean `secret sauce`? Even 
if so, it's not clear to me what you mean by that here.)

Correct AFAIK, the core samba project only uses containers to enable building 
and running tests. Our org that Andrew linked above aims to provide container 
focused projects for application-facing builds of Samba and management tools 
around Samba and the container images we build.

Our project: https://github.com/samba-in-kubernetes/samba-container/
Image Repositories: https://quay.io/organization/samba.org

We host a project entirely focused on making running samba file servers in 
Kubernetes easy - samba-operator : https://github.com/samba-in-kubernetes/
samba-operator

Like many open source projects it's not entirely clear how many people or 
organizations are using our code. We get a fairly small but steady trickle of 
feedback that implies people are trying it out and probably using it to solve 
actual problems. I'd love to have you try out our containers, operator, or 
both and if you hit any issues don't hesitate to communicate with us!  We're 
always looking for people who would like to contribute too. :-)

Thanks!
