Getting started with Swarm mode & Create a swarm

This tutorial introduces Docker Swarm mode, which allows you to deploy and manage containerized applications across a cluster of Docker nodes. In Swarm mode, Docker Engine transforms multiple Docker hosts into a single, distributed system, making it easier to scale, orchestrate, and manage applications.

What This Tutorial Covers:

• Initializing a Docker Swarm
• Adding nodes to the Swarm
• Deploying services to the Swarm
• Managing the Swarm

Prerequisites:

• You need three Linux hosts (physical or virtual machines) that can communicate over a network, with Docker installed.
• Open ports between the hosts.
• The IP address of the manager node.
