Twitter users are up in arms because of the decision to retire production systems with a 2 months notice - https://twitter.com/thomashermine/status/976398123215065088 https://twitter.com/garethdiz/status/976188140670017536 https://twitter.com/LenioLabsLLC/status/976201790482915328

It's also due to the fact (which I also tweeted) that Kubernetes is not even supported on the stable release channel of Docker for Mac!

People, yours truly included, seem a bit concerned with the 2 months notice. To be fair docker cloud was never great and hopefully it doesn't have many big customers... But the precedence of shutting down a paid service with 2 months notice is not nice. What would happen if this was docker hub? Panic!

I could see github adding a tab to repos as for a container registry. That would destroy docker hub imo.

GitLab has an integrated container registry since 2016. https://about.gitlab.com/2016/05/23/gitlab-container-registr...

We are extremely worried about the future of Docker Swarm as well. We love Swarm - but we are seeing most work out of the Docker team is to give a migration path to kubernetes. A huge number of docker swarm networking bugs are not being worked on. We will be happy if Docker talks about Swarm becoming a management UX for K8s - but we need visibility. These are production orchestration systems. The migration path is no…

This is already Swarm V2, there was older Swarm, which worked nice enough. It was equivalent of multi-host Docker run, which could filter based on constraints and do bin-packing, and had even support for multi host networking with etcd/consul/zookeeper.

Then, they cancelled it, no more patches, no mention of it anywhere unless you know where to look.

Then they created Swarm Mode, and add the concept of "services" which sucks compared to regular run because it lacked so many options the run command had, it took more than 6 months to implement most of them.

Genuine question - what makes you think that Kubernetes has won?

Genuine question - what makes you think that Kubernetes has won? Well, "won" in quotes. I am not a k8s fanboy or anything, I simply observe that all the major cloud providers are offering managed k8s services that have superseded their own proprietary container-type offerings. For better or worse that's where the momentum is. If you wanted to containerize your stack right now, k8s then pick one of the big 3, seems li…

For better or worse that's where the momentum is. If you wanted to containerize your stack right now, k8s then pick one of the big 3, seems like a safe bet.

kubernetes got released more than a year earlier. And it wasn't until 2016 that people actually started to take docker-swarm seriously. Thats a two year headstart...

docker-swarm would've needed several really impactful feature to offset that. It didn't really. The only real upsite is how easy it is to install and maintain. But that's hardly important with pretty cheap hosted solutions around (at least cheap in comparison to hiring several SRE to maintain the cluster).

But thats just my opinion as a user.

Why did you pick Swarm for production?

We followed Swarm from the beginning, but after a few releases at v0.4 it was clear not to ever use Swarm, and that it mostly was the Docker PR machine that made it sound nice, and not the actual features.

Maybe it got better later on, but the first several Swarm announcements seemed really off-putting to me.

We ended up on Mesos/Marathon, not that that has a bright future either, but it was at least capable of restarting containers from the beginning..

Just migrate to Kubernetes. It has won.

We're going with Swarm exactly because of the reasons you've listed. The EE part is a bit flaky sometimes (I'm looking at you, UCP), but Swarm is brilliant.

I agree - but I'm now very afraid. I'm beginning to wonder if its not better to just swallow the pain and just go k8s. I would love it (and pay for it) if Swarm says that it is a opinionated distro (ingress/overlay) + management layer on top of k8s. The silence is deafening and not nice.

I don't think that you need to be afraid and migrate just because of that. Swarm is not a service, so if they stopped developing it then you'd have plenty of time figuring out how to move away because your Swarm clusters would not stop working.

Also, there are very large Swarm installations in production at large companies, so I'd be surprised if Docker cancelled the product (which is their flagship).

The registry itself can be self-hosted easily, however everything on top (authentication, web UI, automation, ...) is surprisingly difficult. Plus technical challenges as pointed out by other commenters.

GitLab includes a full docker registry, with all that. Just run a custom GitLab instance, and you get all that for free. For my open source projects on git.kuschku.de I also have a gitlab container registry on k8r.eu, and it’s been amazing to work with.

Interesting, I didn’t know that. We host a registry with HTTP simple auth and it works for us because we don’t need all that.

> Twitter users People . People are up in arms. Anyway, yeah, that's insane. Even Google, who constantly shuts stuff down, usually does so with way more heads up. For comparison, Google Reader, a completely free service, shut down with 3.5 months advance notice. Google Wave got almost 6 months notice.

> Google Reader It still hurts.

It was the day RSS died for me
