From a container running in docker, you can always reference host.docker.internal which resolves to the hostname of your host.  If you need an external IP address of the host, then you'll need to do something to pass in the ipaddress to the container

Congrats everyone.  There were so many worthy projects this time around that voting was really tricky.

It's a good question.  I had thought raising an irisbuiltins.SQLError would do the trick, but it still returns the wrapped exception you see.  I'll put in for an enhancement.

This is a temporary problem. We've having problems internally with our ARM container build servers and didn't want to hold up the preview release while we fix it.  We expect these problems to be resolved before 2022.3's GA.
