Docker Swarm vs Kubernetes
Explore the fundamentals of Docker Swarm and Kubernetes, focusing on their architectures, setup processes, and container management capabilities. Understand when to use Docker Swarm for smaller container deployments and why Kubernetes is preferred for large-scale, secure, and automated container orchestration. Gain practical insights into starting and managing Docker Swarm clusters and appreciate Kubernetes' advanced features like a GUI dashboard and autoscaling.
What is Docker swarm?
A Docker swarm is a group of machines that are running Docker as part of a cluster. It’s based on the leader-follower architecture. We have one manager node and multiple worker nodes. Docker software runs on top of each node. The swarm manager manages all the worker nodes.
To work with Docker swarm, we need to install Docker Machine in our system. It comes preinstalled with Docker software in the case of Windows and macOS.
