Docker Swarm is a container orchestration tool built into the Docker Engine, allowing users to create and manage a cluster of Docker Engines for deploying application services.
Docker Swarm is a container orchestration tool integrated directly into the Docker Engine. It enables users to create and manage a swarm of Docker Engines, effectively turning multiple Docker hosts into a single, virtual host. This facilitates the deployment, scaling, and management of containerized applications. Docker Swarm uses a declarative service model, allowing users to define the desired state of their applications, and the swarm manager automatically reconciles any differences between the actual state and the desired state. It features decentralized design, multi-host networking, service discovery, and load balancing. Designed for users intending to use Swarm as a production runtime environment, it simplifies cluster management without requiring additional orchestration software. Current versions of Docker include Swarm mode for natively managing a cluster of Docker Engines called a swarm.

Allows users to define the desired state of their application stack using a declarative approach. The Swarm manager reconciles any differences between the actual and desired state.
Enables the creation of overlay networks that span multiple Docker hosts, allowing containers to communicate across the Swarm.
Swarm manager nodes assign each service a unique DNS name, allowing containers to discover and communicate with each other through DNS lookups.
Distributes traffic across service containers, ensuring high availability and optimal resource utilization.
Allows for incremental updates to services, minimizing downtime and ensuring a smooth transition between versions.
Install Docker Engine on all nodes intended to be part of the Swarm.
Initialize the Swarm on one of the nodes using `docker swarm init`.
Obtain the join token from the manager node using `docker swarm join-token manager` or `docker swarm join-token worker`.
Join worker nodes to the Swarm using the `docker swarm join` command and the worker token.
Join manager nodes to the Swarm using the `docker swarm join` command and the manager token.
Deploy services to the Swarm using `docker service create`.
Scale services using `docker service scale` to adjust the number of tasks running.
