Does this obviate minikube?
For me, yes. I just deleted my minikube and mini shift directories.
sounds good to me!

#112So confused by all the posts from people who say they run Swarm because kubernetes is too complicated or is only for huge deployments. I’ve had all sort of difficulties installing Docker.

This! I wonder if people say it because it is what they heard or from actual experience? I found K8s far easier but seen people say otherwise and suspect there is a bit of an echochamber happening.

#113Re: Docker for Mac with Kubernetes
#114Wow! 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.
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…
Disagree. Do not find using K8s any more complicated and believe it being more complicated is a myth that just gets repeated over and over to be believed it is true and not based on actual experience.
It just sounds accurate to say it is like trying to be like Google. Well if it is but less complicated then there is no down side.
Re: Docker for Mac with Kubernetes
#115I don't understand the use-case here. You want to use Docker+Kubernetes but can't work out the bits to run it in VM's on your own?
I don’t get it either. minikube is trivially installed in my experience with homebrew. Given that running docker on a Mac has been a long and bumpy journey, I’m not sure I’d want to bundle the two together. What am I missing?
If I don't have to run minikube, and instead get something equivalent just by installing Docker for Mac, that's a minor win.
If Docker's local Kubernetes install provides a way to connect to custom registries (e.g. GCR) without installing a third party plugin onto every minikube, I'd consider that a major win.

This is a replacement for minikube, i.e. a local dev k8s cluster.

#117Earlier quoted context omitted.
Thanks for the reply. I agree with what you say. I'm not tying to say people should all jump to k8s. Having options on the market is great. But I was trying to refute the notion that Kubernetes has no advantages unless you're running a huge cluster. My main points where: * It works great with 1 node. * It comes with many features that Swarm does not have that are useful even at 1 node (PersistentVolumes, StatefulSets…
> Docker is not trivial to set up, either. Do you have a concrete example of what you ran into? What do you mean by "secure install"? on osx its just a matter on installing docker4mac and other linux distributions has pre-made packages. I am a linux noob and I was able to setup a 20 machine cluster with swarm trivially on centos7. I was acutally surprised that I was able to do that so trivially, given I have minimal…
I’m referring to all the stuff Docker machine does beyond apt-get install docker. It sets up TLS certs and sockets do you can control the docker daemon remotely. When docker machine works it’s great, but when it doesn’t it’s frustrating.

You're running on GKE. Of course that's easy, they're handling all the difficult parts for you! It's still not that difficult running it on your own servers, but there are many more pain points. Please get some experience with that, then re-evaluate whether Docker or Kubernetes is easier for small deployments.
Right, I agree.
But with your easier Swarm setup, how do you then attach cloud disks directly to your docker container, like a PersistentVolume affords? That one feature makes basically anything worth it, IMO. Most apps are stateful.

#119Earlier quoted context omitted.
Docker isn't easy to install (see my OP). Kubernetes is probably more difficult to install, but it's not more expensive to use GKE than to roll your own Kubernetes elsewhere. And once you understand Kubernetes from a user perspecitve, it's easier to set up on your own.
> it's not more expensive to use GKE than to roll your own Kubernetes elsewhere. $13 per month per egress rule, bandwidth costs a factor of 100 more expensive than dedicated hosters, and costs for hardware 10x of what dedicated hosters offer. I’m not sure what your definition of "more expensive" is, but compared to renting dedicated hardware (e.g., from Hetzner), or colocating, GKE is significantly more expensive. Of…
Maybe it’s my inexperience. I’ve not had to define egress rules yet. I run 1 preemptible n1-standard-2 node and pay for ancillary services. It’s $35-40/month.
Re: Docker for Mac with Kubernetes
#120Earlier quoted context omitted.
Yes. Though I should emphasize that I'm using GKE. So it's zero config, zero ops. I am running a single n1-standard-2 node on GKE for a smallish app right now. Comes to 30-40 dollars a month all in (egress traffic, cloud storage, other services). I am working hard on getting people to use this app, and it's great to know that scaling will be best-in-class if I succeed. But I stress it's not about the scaling. It's ab…
Yet with a Docker Swarm setup, you could get away with probably 10 dollars/month. K8s likely taking more resources than your app containers is why k8s may not be the best option for single node deployments. I've personally tried both orchestration options and much prefer Swarm to smaller deployments. Sure k8s could prepare you better for the future if your app takes off to the moon but that's just premature optimizat…
This might all very well be true, but Swarm doesn’t let you connect cloud disks directly to your containers, to my knowledge.
Also I challenge the $10 because what cloud instances plus ancillary services add up to $10? I’m talking 2 CPUs and 7.5gb RAM.
