Still, if you had to place money on whether Swarm or Kubernetes (and its lightweight variants) are going to be around in five, ten, or twenty years, the smarter bet would be on Kubernetes. At the time of the writing of this article, no one has officially announced the discontinuation of Swarm, and there is good reason to believe that if Mirantis isn’t interested in helping to maintain it, the community would.

To be clear, this doesn’t mean Swarm has no future, despite rumors that you may have heard to the contrary. The biggest drawback of Swarm is that, following the Mirantis acquisition of Docker Enterprise in November 2019, the future of Swarm remains somewhat uncertain. On the other hand, a few cons of Swarm can make a case against choosing Swarm over one of the lightweight Kubernetes implementations. Thus, if you want a lightweight orchestrator that’s also well-documented and well-integrated with other tools, Swarm is a better choice overall.
#Docker swarm vs kubernetes 2019 how to
When you use Swarm, you can work from the Docker CLI that you probably already know how to use (assuming you have worked with containers previously). Kubernetes is more complicated to install, even if you use one of its lightweight variants.
#Docker swarm vs kubernetes 2019 install
This means that, on a single host, you can install Swarm in just a few commands and be up and running in minutes. On most Linux distributions, installing Swarm is as simple as installing the Docker Engine package. But, for a simpler, single-host environment, there’s an argument to be made that Swarm has just the right amount of functionality to do what you need without making things too complicated for you. This might be a downside in a highly complex, large-scale deployment where you need all of Kubernetes’s features. There are several reasons why you might consider using Swarm, especially for small-scale deployments:Īt the end of the day, Swarm is less complicated to configure and manage than Kubernetes. Docker Swarm benefits for lightweight environmentsīut, that doesn’t mean Docker Swarm has nothing to offer. Kubernetes ate Docker’s lunch a year or two ago and Kubernetes has become the go-to orchestration solution for most large-scale container deployments. I don’t think it’s going too far to say that, at this point, many folks have almost written off Docker Swarm as a production-grade container orchestration tool. A general comparison of single-host Docker Swarm vs. We’ll also touch on where Docker Compose fits within all of this too. We’ll consider not just vanilla Kubernetes but also lightweight Kubernetes variants like k3s, Minikube, and MicroK8s. With that reality in mind, here’s a look at the benefits and drawbacks of Docker Swarm vs. But, what if you’re running your containerized app on a single host or a small cluster? In that case, the considerations for choosing Swarm or a Kubernetes implementation tend to be different. Kubernetes focus on large-scale deployments.
