Unable to connect to remote docker host when using SSH

[fasterinnerlooper]

I am connecting from a VM running in Parallels to the host Mac OS's Docker instance. I have successfully been able to run a docker pull hello-world but I am unable to use the sqlcmd create mssql command. Here is the output from the Windows side:

1 pwsh> sqlcmd create mssql --accept-eula
Downloading mcr.microsoft.com/mssql/server:latest

HINT:
  1. Is a container runtime installed on this machine (e.g. Podman or Docker)?
        If not, download desktop engine from:
                https://podman-desktop.io/
                or
                https://docs.docker.com/get-docker/
  2. Is a container runtime running?  (Try `podman ps` or `docker ps` (list containers), does it return without error?)
  3. If `podman ps` or `docker ps` works, try downloading the image with:
        `podman|docker pull mcr.microsoft.com/mssql/server:latest`

Are you able to run:

docker pull mcr.microsoft.com/mssql/server:latest

(this is the basically the same command sqlcmd create is running at this time (you can also run sqlcmd with a --verbosity 4 flag to get the call stack at the failure, so we can see exactly this API call is failing)

Hi.
I ran this and the original command and it looks like the command inside sqlcmd might not be taking the $env:DOCKER_HOST env var into consideration.

Here is the output:

0 pwsh> docker pull mcr.microsoft.com/mssql/server:latest
