OpenShift Node

Node service installation

Requirements

• Ansible 2.2
• One or more Master servers
• A RHEL 7.1 host pre-configured with access to the rhel-7-server-rpms, rhel-7-server-extras-rpms, and rhel-7-server-ose-3.0-rpms repos

Role Variables

From this role:

Name	Default value
openshift_node_start_options	UNDEF (Optional)	Options to pass to node start cmdline
oreg_url	UNDEF (Optional)	Default docker registry to use
oreg_url_node	UNDEF (Optional)	Default docker registry to use, specifically on the node
openshift_persistentlocalstorage_enabled	false	Enable the persistent local storage

openshift_node_start_options can be used for passing any start node option, e.g.:

--enable=kubelet,plugins

Which would have a node running without kube-proxy and dns.

Notes

Currently we support re-labeling nodes but we don't re-schedule running pods nor remove existing labels. That means you will have to trigger the re-schedulling manually. To re-schedule your pods, just follow the steps below:

oc adm manage-node --schedulable=false ${NODE} oc adm manage-node --drain ${NODE} oc adm manage-node --schedulable=true ${NODE} `

If you are using version less than 1.5/3.5 you must replace --drain with --evacuate.
