OpenShift Templates

This directory contains templates to deploy tooling on OpenShift.

Prepare the nodes you want to monitor

The nodes need to have pbench-agent, collectd images on it. The qcow images generated by the image provisioner already has the images baked in. In case the nodes doesn't have the images, please pull them from dockerhub:

pbench-agent

$ docker pull ravielluri/image:agent
$ docker tag ravielluri/image:agent pbench-agent:latest

collectd

$ docker pull ravielluri/image:collectd
$ docker tag ravielluri/image:agent collectd:latest

Label the nodes with a pbench_role=agent label

$ oc label node <node> pbench_role=agent

Create a service account and add it to the privileged scc

$ oc create serviceaccount useroot
$ oc adm policy add-scc-to-user privileged -z useroot

Create pbench-agent pods and patch it

$ oc create -f openshift_templates/performance_monitoring/pbench/pbench-agent-daemonset.yml
$ oc patch daemonset pbench-agent --patch \ '{"spec":{"template":{"spec":{"serviceAccountName": "useroot"}}}}'

Create a configmap to feed credentials to the collectd pod

$ oc create -f openshift_templates/performance_monitoring/collectd/collectd-config.yml

Create collectd pods and patch it

$ oc create -f openshift_templates/performance_monitoring/collectd/collectd-daemonset.yml
$ oc patch daemonset collectd --patch \ '{"spec":{"template":{"spec":{"serviceAccountName": "useroot"}}}}'
