Daniel Oliveira commented on BEAM-4148:
---------------------------------------
I ran into this issue while trying to get Validates Runner tests working for
the Reference Runner. This issue prevents running those on Macs, and most
likely will also affect the Flink Validates Runner tests since they use Docker
similarly. I'm considering taking this bug, but a bit hesitant since I have
very little experience with Docker. What's missing from your example commit
that's holding it back from being submitted as a PR?
PS: For reference, I also found this link relating to the issue:

> Key: BEAM-4148
> URL: https://issues.apache.org/jira/browse/BEAM-4148
> Project: Beam
> Issue Type: Improvement
> Components: runner-core
> Reporter: Ben Sidhom
> Priority: Minor
>
> Docker for Mac does not allow host networking and thus will not allow SDK
> harnesses to access runner services via `localhost`. Instead, a special DNS
> name is used to refer to the host machine: docker.for.mac.host.internal.
> (Note that this value sometimes changes between Docker releases).
> We should attempt to detect the host operating system and return different
> API descriptors based on this.
> See
> [https://github.com/bsidhom/beam/commit/3adaeb0d33dc26f0910c1f8af2821cce4ee0b965]
> for how this might be done.
