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

Docker for Mac is running in VM anyway, these kind of issues related to slow IO was around more than year. Main reason I run linux on my macbook

Wow! Did Docker give up swarm? I thought there was a time when Docker didn't like the existence of k8s all that much. Anyways, I envision this being very useful for development, may even replace my docker-compose based test setup.

Your docker compose yml is trivially reusable for Swarm. We run it in production and is spectacular . The complexity overhead of kubernetes may be premature when you don't have massive requirements

That's the thing, we use k8s in production and I just used docker-compose for testing in my device environment for the sake of simplicity. Though over time it became not so simple to maintain two parallel config as the system grown up.

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 less complicated at all.

The future of Docker, Inc. is of course Docker EE, and the future of Docker EE is _not_ the scheduler, it's everything around it.

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.

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 while others did not. Even a single well thought out detailed bug report would make it much easier to investigate the issue.

This is a Kubernetes issue, the same issue on Minikube and Docker for Mac. The Kube API server uses a lot of CPU when idle. We are trying to diagnose what is happening.
