Docker Swarm vs. Kubernetes
May 22, 2021
Why would you be interested in clusters in the first place? Containers already provide quite a few benefits themselves, so what’s extra with Docker Swarm and Kubernetes ?
Here are some of the features you get with clusters; Auto‑scaling, Load balancing, Abstracting single machines, Zero-downtime deployments, Deployment rollback, Simplified Networking, High Availability.
Docker Swarm
- Created by Docker Inc.
- Part of a default installation
- Uses the same Docker CLI and API
- Works with Docker Compose services
Kubernetes
- Created by Google
- Based on Borg (internal tool used to run google search)
- Introduces new concepts such as pods and deployments
- Features own API and CLI (not similar to Docker)
- Several distributions and managed services exist
