Docker Certified Associate Certification Training Course - Docker Swarm Setup

The video tutorial explains how to log into a Docker manager using SSH, initiate a Docker Swarm, and configure it by providing the manager's IP address. It covers adding worker nodes to the Swarm using tokens and viewing the Swarm's configuration with the Docker Info command. The tutorial also demonstrates how to list all nodes, including their IDs, hostnames, and roles, using Docker commands.
