Re: [kubernetes-users] kops and pod eviction

2017-01-01 Thread Yervand Aghababyan 
I'm looking for a way to configure these options
http://kubernetes.io/docs/admin/out-of-resource/ when launching the
kubelet via kops.

Re: [kubernetes-users] kops and pod eviction

2017-01-01 Thread 'Timo Reimann' via Kubernetes user discussion and Q 
I'm not familiar with kops but I'd guess you could achieve something 
similar by employing memory resources 

 and 
resource quotas  to prevent 
containers from requesting/consuming more memory than a specified limit. 
>From my understanding, containers exceeding the resource limit would be 
evicted automatically (subject to the QoS classes they fall into).

(Disclaimer: I haven't used resource constraints to the extent described, 
so I'm mostly interpreting the available documentation in best-effort 
manner.)

HTH.

Re: [kubernetes-users] kops and pod eviction

2016-12-31 Thread Yervand Aghababyan 
for example I want the kubelet to monitor the RAM pressure and stop
allocating new pods to the node if the memory usage is above 70%. If it's
above 80 I want some of the pods to be moved to other nodes. This seems to
be entirely possible to do with some kubelet command line arguments but I
don't know how I can customize them if nodeup is starting the
cluster(that's what happens if one uses kops, doesn't it?).

Can you explain what you mean in more detail?
