Question

What are the main differences between the Docker Swarm and Kubernetes?

Answer 1

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
