[kubernetes-users] Re: Kubernetes 1.5.3 and 1.4.9 releases delayed

['Saad Ali' via Kubernetes user discussion and Q]

Rolling back the image changes (PR #41370 
) appears to have 
fixed the CI. All signals are good. I kicked off the 1.5.3 release using 
v1.5.3-beta.0.122+e8852ad4c756b4. Jess, will kick of the 1.4.9 release 
shortly. If there are no hiccups, we should have both releases in a few 
hours.

[kubernetes-users] Re: client-python Beta Release

[Davanum Srinivas]

FYI, OpenStack Magnum has switched over to client-python (from the older
python-k8sclient maintained by some OpenStack folks). OpenStack Kuryr and
Kolla-Kubernetes are going to use the python client real soon now.

Thanks,

[kubernetes-users] Re: How to create dynamic PVC's over an NFS PV

[Eric Jaw]

Thanks! But turns out because of requiring kernel modules, NFS can't run 
within LXC, but this would be a good solution if I get around to running 
NFS in a KVM

[kubernetes-users] Can a gcePersistentDisk mounted readOnly into multiple pods also be mounted readWrite into a single pod (e.g. a k8s Job)?

[dan . gardner]

Use case:  I was hoping to run a k8s Deployment volume mounting a common PD as 
readOnly and then use a single k8s (cron)Job to manage the content of the PD.  
But alas it s not working.  Any ideas please, details below ?

GKE: Master & Node versions: 1.5.2 [not using alpha features, hence Job not 
cronJob]

1. SUCCESS: Mounting a PD xyz as gcePersistentDisk readOnly into a k8s 
deployment running on node-pool 123, all pods can mount the volume.

2. SUCCESS: Mounting a PD xyz as gcePersistentDisk readWrite into a k8s Job 
running on node-pool 456, the Pod created for the job can mount the volume.

3. FAIL:  Being able to do both #1 & #2 simultaneously.

I was hoping since I've segregated the Deployment & the Job onto different 
nodes that this would work.

For the record, I found an even more to the point example, in the Pachyderm 
codebase now:

[kubernetes-users] Dashboard: CPU/Memory Usage metrics not shown

[mdietze]

I am running a Kubernetes cluster of one master and two minions on CentOS VMs 
which was installed using the CentOS installation guide from kubernetes.io. 

I then installed the dashboard using the yaml from the git repo (using the 
rawgit link). 

The dashboard works, however I do not see the CPU/Memory Usage metrics on the 
"Workloads" and the "Conditions" section on the "Nodes" page. 

Are these features only available on GCE instances? Or am I missing something?
