+# Deployment Topology – Epsilon
+
+If you are looking for information on how to deploy the Epsilon based DT,
+then please see the [README](../../examples/dt/uni05epsilon/README.md)
+in the examples directory.
+
+This directory `dt/uni05epsilon/` exists so that
+the [kustomization.yaml](../../examples/dt/uni05epsilon/kustomization.yaml)
+in the examples directory of `uni05epsilon` topology reference it by path
+as a component.

+# Deployment Topology – Epsilon
+
+This document contains a list of integration test suites that would be
+executed against the below specified topology of Red Hat OpenStack Services
+on OpenShift. It also contains a collection of custom resources (CRs) for
+deploying the test environment.
+
+
+## Purpose
+
+This topology is used for executing integration tests that evaluate the
+`default` backends of the below mentioned services.
+
+
+## Environment
+
+
+### Nodes
+
+| Role              | Machine Type | Count |
+| ----------------- | ------------ | ----- |
+| Compact OpenShift | vm           |   3   |
+| OpenStack Compute | vm           |   3   |
+
+
+### Networks
+
+| Name         | Type     | Interface | CIDR            |
+| ------------ | -------- | --------- | --------------- |
+| Provisioning | untagged | nic1      | 172.22.0.0/24   |
+| Machine      | untagged | nic2      | 192.168.32.0/20 |
+| RH OSP       | trunk    | nic3      |                 |
+
+
+#### VLAN networks in RH OSP
+
+| Name        | Type        | CIDR              |
+| ----------- | ----------- | ----------------- |
+| ctlplane    | untagged    | 192.168.122.0/24  |
+| internalapi | VLAN tagged | 172.17.0.0/24     |
+| storage     | VLAN tagged | 172.18.0.0/24     |
+| tenant      | VLAN tagged | 172.19.0.0/24     |
+| external    | VLAN tagged | 192.168.32.0/20   |
+
+
+### Services, enabled features and configurations
+
+| Service          | configuration           | Lock-in coverage?  |
+| ---------------- | ----------------------- | ------------------ |
+| Barbican         | (default)               | Must have          |
+| Cinder           | iSCSI/netapp, NFS, ceph | Must have          |
+| Cinder Backup    | Swift                   | Must have          |
+| Glance           | cinder/NFS, ceph, swift | Must have          |
+| Horizon          | N/A                     | Must have          |
+| Ironic           |                         | Must have          |
+| Neutron          | Geneve (OVN)            | Must have          |
+| Octavia          | act-stby                | Must have          |
+| Swift            | (default)               | Must have          |
+
+
+#### Support services
+
+The following table lists services which are not the main focus of the testing
+(which may be covered by additional scenarios), but are required for the DT to
+work properly and can be deployed with any/default configuration.
+
+| Service          | Reason                     |
+| ---------------- |--------------------------- |
+| Nova             | needed by scenario testing |
+| Keystone         | needed by all services     |
+| Heat             | needed by Telemetry        |
+| Redis            | needed by Octavia          |
+
+
+### Additional configuration
+
+- Always-on, default services and features: TLSe
+- Two additional fake baremetal nodes
+- Availability zones for OVN (zone-1 & zone-2)
+- iSCSI service is enabled on all OpenShift nodes.
+
+
+#### iSCSI
+
+It is assumed *iSCSI* services are enabled in all nodes participating in the
+Red Hat OpenShift cluster. If not, a `MachineConfig` similar to the below one
+is applied. The node would be *rebooted* after applying the configuration.
+
+```YAML

+## Workflow
+
+1. [Install the OpenStack K8S operators and their dependencies](../../common/README.md)
+2. [Configure and deploy the OpenStack control plane](control-plane.md)
+4. [Configure and deploy the OpenStack data plane](data-plane.md)
