It uses internal distributed State store. It does not need an external database to operate. Simple: Swarm Mode is operationally simple and minimizes infrastructure dependencies.Swarm Mode uses mutual TLS for node authentication, role authorization and transport encryption, automating both certificate issuance and rotation. Secure: Node communication and membership within a Swarm are secure out of the box.Distributed: Swarm Mode uses the Raft Consensus Algorithm in order to coordinate and does not rely on a single point of failure to perform decisions.etc.).Īs always Docker focused on following three features for Swarm Mode:
With Swam Mode, all of the popular Swarm Clustering ecosystem is now simply a part of single/same old) Docker Engine with no dependence on any 3rd party software! And still compatible with all the existing Docker CLI and Tooling (ex: docker cli, docker compose, dokku etc. As of Jas DockerCon 2016, Docker has yet again won the heart of millions by releasing Docker Swarm Mode which has all the required functionalities of a full-fledged container clustering and orchestration!
