hostVar is used for the '--host' / '-H' flag to set [ClientOptions.Hosts]. The [ClientOptions.Hosts] field is a slice because it was originally shared with the daemon config. However, the CLI only allows for a single host to be specified. hostVar presents itself as a "string", but stores the value in a string slice. It produces an error when trying to set multiple values, matching the check in [getServerHost].

The non-reference docs have been moved!
The documentation for Docker Engine has been merged into the general documentation repo.
See the README for instructions on contributing to and building the documentation.
If you'd like to edit the current published version of the Engine docs, do it in the master branch here: https://github.com/docker/docker.github.io/tree/master/engine
If you need to document the functionality of an upcoming Engine release,
use the vnext-engine branch:
https://github.com/docker/docker.github.io/tree/vnext-engine/engine
The reference docs have been left in docker/docker (this repo), which remains the place to edit them.
The docs in the general repo are open-source and we appreciate your feedback and pull requests!
