Check also the latest (docker 19.03) docker context command.

Ajeet Singh Raina ) illustrates it in "Docker 19.03.0 Pre-Release: Fast Context Switching, Rootless Docker, Sysctl support for Swarm Services"

A context is essentially the configuration that you use to access a particular cluster.

Say, for example, in my particular case, I have 4 different clusters – mix of Swarm and Kubernetes running locally and remotely.
Assume that I have a default cluster running on my Desktop machine , 2 node Swarm Cluster running on Google Cloud Platform, 5-Node Cluster running on Play with Docker playground and a single-node Kubernetes cluster running on Minikube and that I need to access pretty regularly.

Using docker context CLI I can easily switch from one cluster(which could be my development cluster) to test to production cluster in seconds.

$ sudo docker context --help
Usage:  docker context COMMAND
Manage contexts
Commands:
  create      Create a context
  export      Export a context to a tar or kubeconfig file
  import      Import a context from a tar file
  inspect     Display detailed information on one or more contexts
  ls          List contexts
  rm          Remove one or more contexts
  update      Update a context
  use         Set the current docker context
Run 'docker context COMMAND --help' for more information on a command.

For example:
