- Docker Swarm is a container orchestration tool that manages a cluster of Docker Engines, which in turn runs a group of Docker containers. Because containers are lightweight, they give you the flexibility to create and manage numerous instances on a single node. Typically, containerized apps span multiple nodes, and hundreds, if not thousands of containers. Needless to say, managing such a
