Comparison between Docker swarm and Kubernetes
You might have heard about Kubernetes. A technology that is very much comparable with Docker Swarm is Kubernetes. Docker swarm is basically an alternative to Kubernetes which is a container orchestration tool. So instead of Docker Deamons, in Kubernetes you would have services called Kubelets that will run on each node and instead of Docker you would have a Kubernetes Engine that actually spends those multiple nodes that make up the cluster and the rest everything is almost the same. You have the same docker containers with the same applications running on that cluster set up.

Docker Swarm supports auto load balancing. |
Kubernetes does not have a support for auto load balancing. |

Docker Swarm does not support auto scaling. Manual scaling has to be configured. |
Kubernetes offers auto scaling. |

Docker Swarm uses third party tools for monitoring |
Kubernetes has built in monitoring. |

Docker Swarm is simpler to install and set up. |
Kubernetes is much more complex to install and set up. |
|
For Docker Swarm you don’t have to learn a new command-line tool. |
For Kubernetes, you must learn how to use Kubectl. |

Docker Swarm is lightweight and limited in functionality. |
Kubernetes has a higher learning curve and is more powerful. |
Docker Swarm: Building a Highly Scalable Cluster
Docker Swarm is one of the most popular container orchestration engines. It is not only used by professional engineers but also by people is their learning phase of how operations work. What makes Docker Swarm so popular is the fact that is very lightweight and very simple to understand – you don’t even have to learn a new CLI for Docker Swarm, we can use it with Docker CLI.
In this article, we will learn about Docker Swarm, its features, and use cases and will also go through a tutorial to create highly scalable clusters in Docker Swarm.
