Instructions
Download the oc 1.5 client and extract 'oc' to same dir as these files.
Bring a cluster up on Openshift 3.5:
oc cluster up --image=registry.access.redhat.com/openshift3/ose --version=v3.5
Login as Admin:
oc login -u system:admin
Label the node
oc get nodes
oc label node 192.168.65.3 label=local
Create a serviceaccount
oc create serviceaccount datadog-agent
Add permissive policy to serviceaccount
oc adm policy add-scc-to-user privileged system:serviceaccount:myproject:datadog-agent
Create the config-map
oc create -f configmap.yaml
Run Daemonset (as service account, with label selector and as a privileged pod)
oc create -f dd-agent-daemonset.yaml
