Docker Swarm is Docker’s native, open-source container orchestration platform that is used to cluster and schedule Docker containers. Swarm differs from Kubernetes in the following ways:
Docker Swarm is more convenient to set up but doesn’t have a robust cluster, while Kubernetes is more complicated to set up but the benefit of having the assurance of a robust cluster
Docker Swarm can’t do auto-scaling (as can Kubernetes); however, Docker scaling is five times faster than Kubernetes
Docker Swarm doesn’t have a GUI; Kubernetes has a GUI in the form of a dashboard
Docker Swarm does automatic load balancing of traffic between containers in a cluster, while Kubernetes requires manual intervention for load balancing such traffic
Docker requires third-party tools like ELK stack for logging and monitoring, while Kubernetes has integrated tools for the same
Docker Swarm can share storage volumes with any container easily, while Kubernetes can only share storage volumes with containers in the same pod
Docker can deploy rolling updates but can’t deploy automatic rollbacks; Kubernetes can deploy rolling updates as well as automatic rollbacks
