Review comment:
Just to clarify, you're using the standard "Docker For Mac", or are you
running your own VM with docker installed in it?
testcontainers has some built-in algorithms that are trying to discover a
few well-known/established patterns for discovering how to connect to the
docker daemon HTTP API.
The most common case is that it's trying to discover the well-known location
of the docker unix socket
When using the standard "Docker for Mac" it's managing all this stuff
automagically (there's a unix socket mounted at `/var/run/docker` on the MacOS
filesystem), and things should "just work"
If you're running your own Linux VM though, testcontainers will probably
some help to figure out how to connect to your docker daemon inside your VM...

> Support OpenSSH client certificates for publickey authentication
> ----------------------------------------------------------------
>
> Key: SSHD-1161
> URL: https://issues.apache.org/jira/browse/SSHD-1161
> Project: MINA SSHD
> Issue Type: New Feature
> Reporter: Alex Sherwin
> Priority: Major
> Original Estimate: 24h
> Time Spent: 20m
> Remaining Estimate: 23h 40m
>
> Support OpenSSH client certificates for publickey authentication
> This extends the existing publickey authentication protocol described in RFC
> 4252 Section 7: https://datatracker.ietf.org/doc/html/rfc4252#section-7
> The extensions are described in
> [https://cvsweb.openbsd.org/src/usr.bin/ssh/PROTOCOL.certkeys?annotate=HEAD]
> Currently the MINA code base supports host key certificates (where the client
> can optionally validate a host certificate), but client certificates are not
> supported (where the client can use a certificate for authentication to the
> server)
