.Prerequisites

* A running OpenShift cluster.
* The `oc` binary file.

The following parameters are available to further configure the OpenShift templates:

include::examples/{project-context}-deploying-image-puller-using-openshift-templates_parameters.adoc[]

.Procedure

*Installing*

. Clone the `kubernetes-image-puller` repository:
+
include::examples/{project-context}-deploying-image-puller-using-openshift-templates_cloning-project.adoc[]

. Create a new OpenShift project to deploy the puller into:
+
include::examples/{project-context}-deploying-image-puller-using-openshift-templates_prepare.adoc[]

. Process and apply the templates to deploy the puller:
+
include::examples/{project-context}-deploying-image-puller-using-openshift-templates_process.adoc[]

*Verifying the installation*

. Confirm that a new deployment, `kubernetes-image-puller`, and a DaemonSet (named based on the value of the `DAEMONSET_NAME` parameter) exist. The DaemonSet needs to have a Pod for each node in the cluster:
