Docker Swarm Docker swarm is one of the crucial components of the Docker ecosystem. Native Docker Clustering with Swarm gives us the ability to do scheduling, high availability, security, and platform scalability. Kubernetes, fleet, Mesos work similar to achieve the same goal. They get layer abstraction for system resources and allows the interfaces to the cluster manager. Docker swarm is NOT a plugin it is built-in into docker engine. A basic docker installation can run swarm cluster it does not require any plugin to install. What is Docker Swarm Orchestration?
