What command is used to run a Docker container?

The command used to run a Docker container is "docker run." This command not only creates a new container from a specified image but also starts it immediately. It allows you to specify various options, such as environment variables, volume mounts, and port mappings, which can tailor the container's behavior to meet specific needs.

In contrast, other options serve different purposes. "docker start" is aimed at starting an already existing container that has been stopped. "docker execute," typically associated with "docker exec," allows you to run additional commands in a running container rather than launching a new one. "docker launch" is not a recognized Docker command, which underscores its inapplicability in this context. Thus, "docker run" stands out as the correct choice for starting new containers.
