Thank you for your blog, it's a great source of knowledge for docker, kubernetes, and swarm, also love the openfaas

No, it didn't. Yes, k8s has 'won' in large-scale deployments, but if you're working at a small shop, then just imitating what Google does with millions of servers is dumb. Do what works at your scale -- and Swarm is extremely easy to manage. Many people ask why would someone use an orchestrator on a small cluster (dozens of hosts). Why not? Swarm is very easy to manage and maintain, using Puppet or Ansible is not les…

> Swarm is very easy to manage and maintain, using Puppet or Ansible is not less complicated The idea that dockerized software somehow is less dependent on configuration management seems to be a popular and completely misguided one. The two trends are completely separate, but I would argue from experience that unless you have absolutely nailed the configuration and integration of all your moving parts, don't even loo…

No, it's not 'less dependent'. The way how it helps is that you can standardize configuration management across environments relatively easily.

Containerization does not result in less moving parts in a given environment; but it does result in less moving parts across the whole development flow (from a developer laptop to a production cluster).

Docker for Mac is not usable today, because of high cpu due IO [1] [1] https://github.com/docker/for-mac/issues/1759

I've never noticed this issue with the stable version. However I'm experiencing high CPU usage whenever I start minikube on my Mac. I just installed Docker edge. We'll see how it goes in the long run but so far with k8s enabled hyperkit uses 25% of a virtual core.

Also noticed this with the version of Kubernetes that comes with DfM. hyperkit consumes around 35% CPU while idle, which amounts to around double the idle battery drain on my MBP.

It is usable for the vast majority of users. If it is causing an issue please file a detailed bug report, with diagnostic ID, also try the Edge releases, and give some information about what you are actually running, for example how to replicate it. Most of the bug reports in that thread are totally unhelpful. Quite likely it is not even the same cause for different people, as some people said it was fixed on Edge wh…

Are you sure it works for vast majority of users? At least in my developers circle who use macOS for web* development - all of them have issues with docker high cpu usage due IO. Some use docker-sync to go around the issue. As for bug reports - zero feedback from anyone on that thread from maintainers. If you are one of the maintainers - it might be good to write this comment on that thread instead of HN * - I unders…

I am not a maintainer but do work on LinuxKit which is used. If docker-sync helps, then that suggests that you have an issue specifically related to file sharing. Please file a new issue, do not add to this one, which explains how to reproduce your development setup. Different setups work very differently (eg polling vs notifications), and people use things very differently, there is no one set of tooling and setup that is "web development", but it sounds like in your company you all use similar tools and setup, so it is not surprising you all have the same issue. We have a performance guide here https://docs.docker.com/docker-for-mac/osxfs/ that covers some use cases.

Minor nitpick, it's called macOS now.

I don't understand why people refer to pre-Sierra releases as macOS. Sierra and onwards is called macOS. guillaumerose was referring to all versions, so both "all OS X versions" and "all macOS versions" would be wrong, no...?

>I don't understand why people

Because it's a bother to keep in mind when they introduced the new name? Or release names? It's hard to imagine that someone would actually be talking about certain number of releases this way.

PS: Apple's stupid marketing bs strikes again.

I find that Swarm is the only thing that fits my use case of just shipping. There's so much complexity and overhead with kubernetes and often I just want something that works so I can ship it. You just can't beat Swarm for building an insta-cluster that works well and quickly gets you where you want to be. I'm sure kubernetes is great if you have forty datacenters around the globe, but I don't, and neither does anybody I'm building services for.

This is very interesting. I've been looking for middle ground between Dokku and Kubernetes, I'll give swarm a try. Does it handle ingress at all? vhosts, TLS certificates, etc?

ingress is the most beautiful part of Swarm - it is built in. however, it does not do termination. You should trivially include a haproxy/nginx pod/service/vm to do the termination for you. One of the cool new infrastructure features is Docker Cloud - which allows you to "bring your own nodes" for 15$/node/month and setup Swarm. https://docs.docker.com/docker-cloud/cloud-swarm/using-swarm...

I'm using https://github.com/containous/traefik with Swarm for termination, Let's Encrypt and routing with success. Configuration is handled with service labels.
