Chapter 1. Preparing to deploy OpenShift Data Foundation


When you deploy OpenShift Data Foundation on OpenShift Container Platform using local storage devices, you can create internal cluster resources. This approach internally provisions base services and all applications can access additional storage classes.

Before you begin the deployment of Red Hat OpenShift Data Foundation using local storage, ensure that your resource requirements are met. See requirements for installing OpenShift Data Foundation using local storage devices.

On the external key management system (KMS),

After you have addressed the above, follow these steps in the order given:

1.1. Requirements for installing OpenShift Data Foundation using local storage devices

Node requirements

The cluster must consist of at least three OpenShift Container Platform worker nodes with locally attached-storage devices on each of them.

  • Each of the three selected nodes must have at least one raw block device available to be used by OpenShift Data Foundation.
Note

Make sure that the devices have a unique by-id device name for each available raw block device.

  • The devices you use must be empty; the disks must not include physical volumes (PVs), volume groups (VGs), or logical volumes (LVs) remaining on the disk.

For more information, see the Resource requirements section in the Planning guide.

1.2. Enabling cluster-wide encryption with KMS using the Token authentication method

To enable the key value backend path and policy in Vault for the Token authentication, follow the procedure:

Prerequisites

Procedure

  1. Enable the Key/Value (KV) backend path in Vault.

    For Vault KV secret engine API, version 1:

    Copy to Clipboard Toggle word wrap
    $ vault secrets enable -path=odf kv

    For Vault KV secret engine API, version 2:

    Copy to Clipboard Toggle word wrap
    $ vault secrets enable -path=odf kv-v2
  2. Create a policy to restrict users to perform a write or delete operation on the secret using the following commands.

    Copy to Clipboard Toggle word wrap
    echo '
    path "odf/*" {
      capabilities = ["create", "read", "update", "delete", "list"]
    }
    path "sys/mounts" {
    capabilities = ["read"]
    }'| vault policy write odf -
  3. Create a token matching the above policy.

    Copy to Clipboard Toggle word wrap
    $ vault token create -policy=odf -format json
