+# Deploying and Managing Openshift Data Foundation
+
+This example shows how to deploy and manage the Openshift Data Foundation (ODF) on IBM Cloud VPC based RedHat Openshift cluster. Note this template is still in development, so please be advised before using in production.
+
+This sample configuration will deploy the ODF, scale and upgrade it using the "ibm_container_addons" and "kubernetes_manifest" from the ibm terraform provider and kubernetes provider respectively.
+
+For more information, about
+
+* ODF Deployment, see [Deploying OpenShift Data Foundation on VPC clusters](https://cloud.ibm.com/docs/openshift?topic=openshift-deploy-odf-vpc&interface=ui)
+* ODF Management, see [Managing your OpenShift Data Foundation deployment](https://cloud.ibm.com/docs/openshift?topic=openshift-ocs-manage-deployment&interface=ui)
+
+#### Folder Structure
+
+```ini
+├── openshift-data-foundation
+│   ├── addon
+│   │   ├── ibm-odf-addon
+│   │   │   ├── main.tf
+│   │   ├── ocscluster
+│   │   │   ├── main.tf
+│   │   ├── createaddon.sh
+│   │   ├── createcrd.sh
+│   │   ├── updatecrd.sh
+│   │   ├── updateodf.sh
+│   │   ├── deleteaddon.sh
+│   │   ├── deletecrd.sh
+│   │   ├── main.tf
+│   │   ├── variables.tf
+│   │   ├── schematics.tfvars
+```
+
+* `ibm-odf-addon` - This folder is used to deploy a specific Version of Openshift-Data-Foundation with the `odfDeploy` parameter set to false i.e the add-on is installed without the ocscluster using the IBM-Cloud Terraform Provider.
+* `ocscluster` - This folder is used to deploy the `OcsCluster` CRD with the given parameters set in the `schematics.tfvars` file.
+* `addon` - This folder contains scripts to create the CRD and deploy the ODF add-on on your cluster. `The main.tf` file contains the `null_resource` to internally call the above two folders, and perform the required actions.
+
+#### Note
+
+You do not have to change anything in the `ibm-odf-addon` and `ocscluster` folders. You just have to input the required parameters in the `schematics.tfvars` file under the `addon` folder, and run terraform.
+
+## Usage
+
+### Option 1 - Command Line Interface
+
+To run this example on your Terminal, first download this directory i.e `examples/openshift-data-foundation/`
+
+```bash
+$ cd addon/4.16.0
+```
+
+```bash
+$ terraform init
+$ terraform plan --var-file schematics.tfvars
+$ terraform apply --var-file schematics.tfvars
+```
+
+Run `terraform destroy --var-file schematics.tfvars` when you don't need these resources.
+
+### Option 2 - IBM Cloud Schematics
+
+To Deploy & Manage the Openshift-Data-Foundation add-on using `IBM Cloud Schematics` please follow the below documentation
+
+https://cloud.ibm.com/docs/schematics?topic=schematics-get-started-terraform
+
+Please note you have to change the `terraform` keyword in the scripts to `terraform1.x` where `x` is the version of terraform you use in IBM Schematics, for example if you're using terraform version 1.3 in schematics make sure to change `terraform` -> `terraform1.3` in the .sh files.
+
+## Example usage
+
+### Deployment of ODF
+
+The default schematics.tfvars is given below, the user should just change the value of the parameters in accorandance to their requirment.
+
+```hcl
+ibmcloud_api_key = "" # Enter your API Key
+cluster = "" # Enter the Cluster ID
+region = "us-south" # Enter the region
+
+# For add-on deployment
+odfVersion = "4.16.0"
+
+# For CRD Creation and Management
+autoDiscoverDevices = "false"
+billingType = "advanced"
+clusterEncryption = "false"
+hpcsBaseUrl = null
+hpcsEncryption = "false"
+hpcsInstanceId = null
+hpcsSecretName = null
+hpcsServiceName = null
+hpcsTokenUrl = null
+ignoreNoobaa = "false"
+numOfOsd = "1"
+ocsUpgrade = "false"
+osdDevicePaths = null
+osdSize = "512Gi"
+osdStorageClassName = "ibmc-vpc-block-metro-10iops-tier"
+workerPools = null
+workerNodes = null
+encryptionInTransit = false
+taintNodes = false
+addSingleReplicaPool = false
+prepareForDisasterRecovery = false
+ignoreNoobaa = false
+disableNoobaaLB = false
+enableNFS = false
+useCephRBDAsDefaultStorageClass = false
+resourceProfile = "balanced"
+```
+
+### Scale-Up of ODF
+
+The following variables in the `schematics.tfvars` file can be edited
+
+* numOfOsd - To scale your storage
+* workerNodes - To increase the number of Worker Nodes with ODF
+* workerPools -  To increase the number of Storage Nodes by adding more nodes using workerpool
+
+```hcl
+# For CRD Management
+numOfOsd = "1" -> "2"
+workerNodes = null -> "worker_1_ID,worker_2_ID"
+```
+
+### Upgrade of ODF
+
+The following variables in the `schematics.tfvars` file should be changed in order to upgrade the ODF add-on and the Ocscluster CRD.
+
+* odfVersion - Specify the version you wish to upgrade to
+* ocsUpgrade - Must be set to `true` to upgrade the CRD
+
+```hcl
+# For ODF add-on upgrade
+odfVersion = "4.16.0" -> "4.17.0"
+
+# For Ocscluster upgrade
+ocsUpgrade = "false" -> "true"
+```

+
+## Note
+
+* Users should only change the values of the variables within quotes, variables should be left untouched with the default values if they are not set.
+* `workerNodes` takes a string containing comma separated values of the names of the worker nodes you wish to enable ODF on.
+* On `terraform apply --var-file=schematics.tfvars`, the add-on is enabled and the custom resource is created.
+* During ODF update, please do not tamper with the `ocsUpgrade` variable, just change the value to true within quotation, without changing the format of the variable.
+* During the `Upgrade of Odf` scenario on IBM Schematics, please make sure to change the value of `ocsUpgrade` to `false` after. Locally this is automatically handled using `sed`.
