Deploy the operator

Apply the all-in-one template, as described in the quickstart.

oc create -f https://download.elastic.co/downloads/eck/2.8.0/crds.yaml
oc apply -f https://download.elastic.co/downloads/eck/2.8.0/operator.yaml

[Optional] If the Software Defined Network is configured with the ovs-multitenant plug-in, you must allow the elastic-system namespace to access other Pods and Services in the cluster:
```
oc adm pod-network make-projects-global elastic-system
```
Create a namespace to hold the Elastic resources (Elasticsearch, Kibana, APM Server, Enterprise Search, Beats, Elastic Agent, Elastic Maps Server, and Logstash):

A namespace other than the default namespaces (default, kube-, openshift-, etc) is required such that default Security Context Constraint (SCC) permissions are applied automatically. Elastic resources will not work properly in any of the default namespaces.

oc new-project elastic # creates the elastic project

[Optional] Allow another user or a group of users to manage the Elastic resources:
```
oc adm policy add-role-to-user elastic-operator developer -n elastic
```
In this example the user developer is allowed to manage Elastic resources in the namespace elastic.
