This does not require creating a context, and can be useful to create an ad-hoc connection with a different engine\n\nBounded code example (external data; do not execute automatically):\n```console\n$ export DOCKER_HOST=ssh://docker-user@host1.example.com\n$ docker info\n<prints output of the remote engine>\n```\n\nAttribution: Adapted from Docker Documentation under Apache-2.0.
