When running in Docker, zonemaster-cli’s --hints option is hard to use

[marc-vanderwal]

When running zonemaster-cli in Docker, one cannot easily use the --hints option: that’s because the hints file usually lives outside the container’s file system.

While it is possible to get a Dockerized zonemaster-cli to run with custom hints, the command line to achieve this isn’t easy to figure out if one is unfamiliar with both Docker and Linux in general.

In a nutshell, the answer is:

$ docker run --mount type=bind,source=/path/to/hints,target=/hints --rm zonemaster/cli:local --hints /hints zone.to.test

I think this use case is worth documenting somewhere.

The use case is probably limited, but it could be worth to be documented under "Advance use" in https://github.com/zonemaster/zonemaster-cli/blob/develop/USING.md

--mount type=bind,source=/path/to/hints,target=/hints

This could be less verbose in the more common form -v /path/to/hints:/hints
