The command to determine which Docker version is installed on your machine can be done using the "docker version" command. This command provides comprehensive output, detailing the client and server version of Docker, including other relevant specifications such as the API version and Go version. It effectively gives a complete overview of the Docker installation, making it suitable for users who want to understand both the client and server compatibility.

While other commands might also provide version-related information, "docker version" is explicitly designed to display version details in a structured manner, making it the most effective choice for this specific inquiry. For example, "docker info" provides a lot of system-related information, but it combines various Docker settings, allowing the version to be part of a larger set of data rather than focusing solely on the versions. The "docker --version" command is a shorthand alternative that also returns the client version, but it does not provide the server's version information or additional context that "docker version" supplies. The "docker status" command does not exist as part of standard Docker command options. This uniqueness in the output makes "docker version" the best option for identifying installed versions accurately.
