Help on an error being seen in a cluster

2018-09-29 Thread Gaurav Ojha
Hi,

I just deployed an OpenShift v3.10 HA cluster. And on each of the nodes, I
see the following error being reported.

Sep 29 19:28:42 master1 origin-node: E0929 19:28:42.143035   23090
summary.go:102] Failed to get system container stats for
"/system.slice/origin-node.service": failed to get cgroup stats for
"/system.slice/origin-node.service": failed to get container info for
"/system.slice/origin-node.service": unknown container
"/system.slice/origin-node.service"

I cannot find any information why I can be seeing this. Can I get some help
on finding why this is happening? This is on a RHEL 7.5 with Docker 1.13.1.

Thanks,
Gaurav

openshift origin all in one

Hello,


I'm wondering with regard to the all-in-one setup:
- I know the documentation doesn't say it's considered production, but what
would the downside be of using this on a VPS to host production apps?
Except for the lack of redundancy obviously, the host goes down and it's
all down, but my alternative would be to not use openshift and use plain
docker on one host, so availability isn't my premium concern. Is it not
recommended from a security perspective, considering how it's setup using
"oc cluster up", or are there other concerns for not using it in production?
- When setting up an all-in-one on an internet-exposed host, how can you
best protect the web console? Isn't it a bit "light" security wise to just
depend on username/password for protection? Is there a possibility to use
multifactor or certificate based authentication? I also tried blocking the
port with iptables and using ssh with port forwarding, but this doesn't
seem to work, both if I set the public-master option to the public ip or
localhost?


Thanks for any help you can provide!


Regards,



Peter
