Kubernetes vs. Docker Swarm: What's the Difference?

Docker Swarm is a great orchestration tool for getting into container orchestration platforms and an excellent starting point for simple to moderately complex workloads and app deployment topologies. A lot of companies still use it, and it works pretty well for production workloads; however for long running clusters you may start to run into some hard to diagnose cluster “state” issues and strange behavior during upgrades (this is based on personal experience); however all in all, its still pretty solid. Swarms selling point is its simplicity.

That said, the biggest problem facing Swarm is that Docker Inc. has, for all practical purposes, abandoned it since their announcement in March of 2018 when they discontinued Docker Cloud and waived the white flag in the container orchestration wars, yielding to Kubernetes.

Despite seemingly to say otherwise, for all practical purposes, looking at actions and not words, Swarm (in its open-source form) does not appear to be something that Docker Inc. has any real interest in maintaining or improving. This is evidenced by the complete lack of responsiveness from anyone at Docker Inc. to long standing Github issues or Docker forum questions about Swarms future. One of the lone positive voices comes from a Docker Captain who still advocates for Swarm and has written some good articles on the subject: “Is Swarm Dead” & “The Future of Docker Swarm”. It would just be nice to hear something from Docker Inc. officially to their still sizeable user base utilizing this technology.

So if you are looking to de-couple yourself from the potential future technical debt that Swarm might bring to your team, company or organization; your next best bet is Kubernetes.

This article is intended to show how Swarm compares to Kubernetes with a fairly simple example of deploying a replicated application to get you started.

50+ Useful Kubernetes Tools for 2020 - Part 2

Introduction

Last year, we provided a list of Kubernetes tools that proved so popular we have decided to curate another list of some useful additions for working with the platform—among which are many tools that we personally use here at Caylent. Check out the original tools list here in case you missed it.

According to a recent survey done by Stackrox, the dominance Kubernetes enjoys in the market continues to be reinforced, with 86% of respondents using it for container orchestration.

And as you can see below, more and more companies are jumping into containerization for their apps. If you’re among them, here are some tools to aid you going forward as Kubernetes continues its rapid growth.

Kubernetes vs. Docker Swarm (k8 vs Docker Swarm)

Basically, both Kubernetes and Docker Swarm both are the container orchestration tool. The rise in interest to containers has in turn brought in higher demands for their deployment and management. Both Kubernetes and Docker Swarm are important tools that are used to deploy containers inside a cluster. So the question arises here is which one to use?

So lets discuss one by one and see the the differances between them.

Introduction to Kubernetes:

The name Kubernetes originates from Greek, meaning helmsman or pilot. Kubernetes is an open-source, portable, and extensible platform for managing containerized workload and services. That facilitates both declarative configuration and automation. Kubernetes manage the containers that run the applications and ensure that there is no downtime into a huge scale production environment.

Introduction to Docker swarm:

Docker swarm is a container orchestration tool, meaning that it allows the user to manage multiple containers deployed across multiple host machines. Docker Swarm is designed to work around four key principles:

  1. Less cluttered/heavy and with just working methodology
  2. No Single Point of Failure option for Docker Swarm
  3. Secure due to auto-generation of security certificates.
  4. Compatibility with Backward versions easily.

Here you get to know that both in some manner are the same , So now let’s check out the differences and see:

Kubernetes Vs. Docker: Primary Differences You Should Know

Kubernetes vs Docker is an essential topic of debate among professionals. Both of them are related to containerization, and both of them have their sets of features. So, the community is divided into two sections, which can lead to confusion.

That’s why you should read this article as we’ve discussed all the significant differences between these two solutions. Let’s get started.

Kubernetes vs Docker Swarm

·Installation and Cluster configuration

Kubernetes:

Setting up a cluster manually is complex. The configurations differ between different operating systems. It requires a lot of pre-planning as far as the setup goes. Components like storage and networks require configurations. Third-party packages like kubectl etc are required.

Docker Swarm:

Installing Docker Swarm clusters is simple. It only requires a few commands to setup a cluster, and then to add further worker or manager nodes. The setup is also OS independent, and so developers don’t have to spend any time learning new commands based on the OS.

· Load balancing

Kubernetes:

It has to be setup manually but is not very complicated. An ingress can be used to load balancing. Pods are exposed as a service.

Docker Swarm:

Load balancing is done by default and ports are assigned automatically. All containers from a cluster remain in a common network.

Docker vs. Kubernetes | Docker vs. Kubernetes Difference

Docker and Kubernetes are two orchestration tools that very popular. Many people have trouble picking one. In this video on Docker vs Kubernetes, we will be comparing these two tools end to end and see which one will suit your needs better.

Today, both Docker and Kubernetes are leading container orchestration tools in the DevOps lifecycle. Docker uses a containerization platform for configuring, building, and distributing containers, while Kubernetes is an Ecosystem for managing a cluster of Docker containers. Docker provides a containerization platform that supports various operating systems such as Linux, Windows, and Mac. It allows us to easily build applications, package them with all required dependencies, and ship it to run on other machines.

The advantage of using Docker is that it provides benefits for both developers as well as a system administrator. While Kubernetes (also known as k8s) is an open-source platform developed by Google. It offers powerful, useful, and scalable tools for managing, deploying complicated containerized applications. The advantage of using Kubernetes is that it provides the best solution for scaling up the containers.

This tutorial will help you to clear up some common confusion surrounding Kubernetes and Docker, and explain what people really mean when they talk about “Docker vs. Kubernetes.”. In this tutorial, we have covered all the important topics such as, What is Docker, What is Kubernetes, How they are different from each other, and much more that will help you to get a hold over these concepts.
