windows 10: host not found in upstream "ubuntu1" on docker compose up

[cigfthomas]

Previously, I have been running through this class and the lab successfully. However, now when run the lab it has the error below. I have seen similar issues (17) but I'm unclear on the resolution. It feels like a permissions/elevated privilege issue. I have tried this as my domain account and using run as administrator.

Below is the error, docker version, .env file contents and a docker command showing the paths in env file will mount.

this something specific to my laptop. I was able to set this up on another laptop (that I am moving to) so this is not worth pursuing. :)
