Could it be that the teams are simply focused on adding K8s support and getting the Docker EE out of Beta?

Public statement on their blog after the K8s announcement in EU:

"But it’s equally important for us to note that Swarm orchestration is not going away. Swarm forms an integral cluster management component of the Docker EE platform; in addition, Swarm will operate side-by-side with Kubernetes in a Docker EE cluster, allowing customers to select, based on their needs, the most suitable orchestration tool at application deployment time."

There's still plenty of PR's and activity in the SwarmKit and Libnetwork repos:

Maybe https://github.com/v2tec/watchtower, but Keel looks cool.

Doesn't support Swarm, but thanks for the pointer.

The difference between reality and Internet news/blogs can sometimes be vast, and we "problem solvers" have to be aware of that. There are hundreds or more enterprise companies using Docker EE, which is using Swarm currently as its orchestrator/scheduler. (see https://www.docker.com/customers) and I also recently ranted about the assumption that everyone is using one thing for orchestration. https://twitter.com/BretFisher/status/958416831659872256

IMO, a healthy ecosystem always has multiple opinions on how to solve a problem.

I'm biased and like Swarm for those that want a great UX (from dev through CI/CD to prod) and their needs match the problems that Swarm solves. I currently teach workshops and consult on Swarm because that's what my circles ask for. It doesn't make anyone wrong or better. These are all opinions on how to create container clusters and some teams like Mesos/DCOS, some Swarm, and some Kubernetes.

In the end, does Swarm solve your problems? If so, stick with it until it doesn't. Docker has publicly stated on their blog months ago that they are not EOL'ing Swarm, despite the news falsely stating Swarms demise. In Docker's main paid product, Docker EE, their new Kubernetes integration actually uses Swarm to help ease K8s deployment AFAIK, so at this point, I feel its future is solid and don't have a problem using it or recommending it. It's still early days for the ecosystem through, so I might be singing a different tune in two years. Swarm may not be the most talked about container orchestrator, but like others, it does solve problems for many people.

One assumption I've made (in my 30+ certs over 20 years, all in sysadmin/tools) is that ops/sysadmin can be much more tool/feature centric. It's rather easy to test someone's ability to know cli options or know the "one way" to configure a tool.

I was interviewed for Virginia Beach "Beach Bums", along with several others in the area... so they must have done some significant work to arrive at this list.

Thanks for post. I've updated with links for each major feature and Windows 10 updates.
