I still use Docker images to deploy several of my Go systems. For one, it's nice to have it integrated into other ecosystems where a "Docker image" is just the base level of functionality. The additional security (even if not necessarily perfect) and isolation isn't all bad either.

It's perfectly fine to compile a Go binary and stick it into a Docker container on its own; it is not obligatory for a Docker container to contain a full Linux installation. I've got a couple of Docker files that are pretty much just

    FROM scratch

    ADD my_binary /

(Usually my bind mounts and the command executed are set up elsewhere for logging and such.)

It is also a convenient way of knowing exactly what your dependencies are... for instance I have several Go containers that also have to include a trusted cert store so they can access remote HTTPS resources correctly. Since you don't need a full Linux install to run a Go binary, it's very easy to use Docker as a complete, human-comprehensible manifest of exactly what is in that container.
