What is Swarm? 

  • A swarm is a cluster of Docker engines, or nodes, where you deploy services 
    • The Docker Engine CLI and API include commands to manage swarm nodes (e.g., add or remove nodes), and deploy and orchestrate services across the swarm 
  • You enable swarm mode for an engine by either initializing a swarm or joining an existing swarm 
    • When you run Docker without using swarm mode, you execute container commands 
    • When you run the Docker in swarm mode, you orchestrate services 
  • You can run swarm services and standalone containers on the same Docker instances.
