[kubernetes-users] alternative to kubeadm for production bare-metal cluster

[Prefer Anon]

I apologize for this rather basic question but I've had a hard time finding 
a canonical answer.  I have a bare-metal ubuntu 16.04 cluster that I'm 
trying to run kubernetes on.  I've managed to get it setup using kubeadm 
using the standard install docs but they later advice against using kubeadm 
in production because its "alpha" software.  I've also been having problems 
like the kube-dns service not resolving non-cluster names (e.g. google.com) 
but I don't even know how to get started debugging it because kubeadm set 
all that stuff up and its a bit of a black box.  Is there a good guide for 
setting up a bare-metal kubernetes cluster?  I've come across the 
"kubernetes the hard way" guide but that seems to be focused on cloud 
providers and it also admits that it forces you to do a lot of manual work 
that's not necessary. 

So what is the recommended way to deploy a bare-metal kubernetes cluster in 
production?

Thanks!

[kubernetes-users] Installing Kubernetes to Centos with Proxy

[ilter P]

Hi,

I need recommendation on how to install kubernetes in a private network ?
I have Centos VMs and they cannot access Internet directly. I need to set 
an http_proxy

So the problem in here for my kubernetes networking. Since I am facing 
following issues:
- Pods cannot see each other if they are in different nodes
- Containers cannot reach outside. f.i,fabric.forge cannot reach 
"https://start.spring.io/";

I could not find any installation instructor where it covers this scenario.

Could you please help please ?

Thanks

I've started documenting the process in the upstream documentation (PR
pending):
https://github.com/castrojo/kubernetes.github.io/blob/ubuntu-lifecycle-revisions/docs/getting-started-guides/ubuntu/installation.md

I'd be happy to walk you through the process in more detail, please feel
free to contact me offlist or in slack (@castrojo), thanks!

Thanks, I messaged you on slack on the kubernetes user channel (@jorge). 
 Please let me know if that doesn't work.

Re: [kubernetes-users] Re: GKE 1.4.0 Container-VM Image (GCI) missing glusterfs-client.

Please feel free to consult this page
https://cloud.google.com/container-engine/docs/node-image-migration
for the latest in GCI and CVM functionality especially the table with
the different mount options. That is the official place to look.

That said realize on GCI the mount functionality is still early access
and has limited testing. As we give it more testing and get more
confident we will be updating this page.

Jing Xu knows the up to date details and should correct me if I am
wrong, but I think gluster support on GCI may not handle large number
of mounts right now. ccing her on this list for the exact numbers.
AFAIK NFSv4  looks very solid and NFSv3 is coming.
