Rancher and Kubernetes on RancherOS

RancherOS
1

I think I did a mistake. I installed rancher and a kubernetes cluster with 3 nodes using rancheos as a base operating system.

However everything I try to do on hosts (like using snmp, setting timezone, etc) fails with errors:

-> running in chroot, ignoring request.
-> Failed to create bus connection: No such file or directory.

In a full-blow Linux distro like CentOS it’s easly to configure base services and add-ons.

Anyone uses kubernetes with rancheros? Have problems? How to setup basic services, like ntp (as a client), set datetime and snmpd?

RancherOS has integrated NTP as a system-docker service. See: https://github.com/rancher/os/blob/master/os-config.tpl.yml#L279

Current RancherOS does not support dbus, you can try starting the dbus service in the container. https://github.com/rancher/os-services/blob/master/images/10-modemmanager/Dockerfile#L9
