Chapter 1. Preparing to deploy OpenShift Data Foundation
Deploying OpenShift Data Foundation on OpenShift Container Platform using dynamic storage devices provides you with the option to create internal cluster resources. This will result in the internal provisioning of the base services, which helps to make additional storage classes available to applications.
Before you begin the deployment of OpenShift Data Foundation, follow these steps:
- Setup a chrony server. See Configuring chrony time service and use knowledgebase solution to create rules allowing all traffic.
Optional: If you want to enable cluster-wide encryption using the external Key Management System (KMS) HashiCorp Vault, follow these steps:
- Ensure that you have a valid Red Hat OpenShift Data Foundation Advanced subscription. To know how subscriptions for OpenShift Data Foundation work, see knowledgebase article on OpenShift Data Foundation subscriptions.
- When the Token authentication method is selected for encryption then refer to Enabling cluster-wide encryption with the Token authentication using KMS.
- When the Kubernetes authentication method is selected for encryption then refer to Enabling cluster-wide encryption with the Kubernetes authentication using KMS.
Ensure that you are using signed certificates on your Vault servers.
NoteIf you are using Thales CipherTrust Manager as your KMS, you will enable it during deployment.
Minimum starting node requirements
An OpenShift Data Foundation cluster is deployed with minimum configuration when the standard deployment resource requirement is not met. See Resource requirements section in Planning guide.
Disaster recovery requirements
Disaster Recovery features supported by Red Hat OpenShift Data Foundation require all of the following prerequisites to successfully implement a disaster recovery solution:
- A valid Red Hat OpenShift Data Foundation Advanced subscription
A valid Red Hat Advanced Cluster Management for Kubernetes subscription
To know how subscriptions for OpenShift Data Foundation work, see knowledgebase article on OpenShift Data Foundation subscriptions.
For detailed requirements, see Configuring OpenShift Data Foundation Disaster Recovery for OpenShift Workloads guide, and Requirements and recommendations section of the Install guide in Red Hat Advanced Cluster Management for Kubernetes documentation.
