It feels downplayed in this article, so I would like to state for the record here, I am a happy user of Docker Swarm.

Swarm has been shown to scale to tens of thousands of hosts, but I found it easy to start with, especially with the Gitlab CI support, which natively brings a Docker container registry.

So I commit, CI builds my containers, stores them in my private registry, and automatically deploys from there to the Swarm in various environments. All this was much easier to setup than the alternatives.

Also, I expect an easy transition should I need to move to Mesos or k8s. If I ever need to. In the mean time I like to keep it simple.

*Marathon on Mesos. :P

As someone rather unfamiliar with the differences in cloud containerization options, I've been extremely confused anytime I see extremely opinionated arguments about cloud infra. This article was a breath of fresh air and is exactly the reference guide that I have been looking for. The author provides a clear history of the development of the titular systems, provides an in-depth overview of their various strengths, and adequately describes the differences in architecture. Overall, an excellent read for the uninitiated.

I have previously tried to investigate why Kubernetes was considered useful [1], or why everyone was losing their minds over Docker [2]. But rarely came away with any clear insights.

Those kind of articles are not so useful, Mesosphere is the company behind DC/OS and Mesos and they have all the interest in the world to say that Mesos is the best. Things like "... are willing to get your hands dirty integrating your solution with the underlying infrastructure" when talking about Kubernetes is unfair, especially if you compare Kubernetes to Mesos and not to Mesosphere DC/OS for which they provide paid services.

It is true that Mesos works on a different level, but, most of all, the two level scheduling is just a different take at the problem of abstracting physical/virtual resources. In the end, both Mesos/Marathon and Kubernetes aim at the same goal: allow developers to stop thinking about servers.

Kubernetes' great advantages is the community (which is unbelievable) and the extensibility it proposes: Third Party Resource or Custom Resource Definition, pluggable webhooks in the API Server and a number of other things that are simply not there in Marathon or any competitor which allow companies to make Kubernetes work best for their use cases.

Some of us love getting our hands dirty. In my honest opinion this whole article seemed very neutral in phrasing. It wasn't until I decided to check the source after having read and enjoyed the entire article, that I discovered that it was written in a Mesos domain. And even then I applaud that they were humble enough to save their own product until the end and didn't seem to exaggerate their sales pitch.

I'm also a user of Docker Swarm - and I love it! I have extensively played with k8s and feel it has a lot of upfront complexity (especially ingress).

I feel people who are beginning to scale from one machine to 10 will love Docker Swarm (and stick with it). While those who have about 100 machines will start with Mesos/K8s.

How do you automate the updating of images on Docker Swarm?
