How do you leave a Swarm cluster in Docker?

The command to leave a Swarm cluster in Docker is "docker swarm leave." This command is specifically designed to remove a node from the Swarm. When executed, it will ensure that the node you are using will no longer participate in the cluster and will not receive any updates or alerts pertaining to the Swarm.

Using the correct command is crucial because Docker commands are very precise, and any minor deviations (like using non-existent commands) will lead to errors. Understanding the correct syntax and command structure in Docker is essential for effective management of containers and clusters.
