Deploying OpenShift Data Foundation using Amazon Web Services

Procedure

1. Log in to the Red Hat Enterprise Linux based node and open a terminal.

2. For each node in your cluster:

   1. Verify that the node has access to the rhel-7-server-extras-rpms repository.

      # subscription-manager repos --list-enabled | grep rhel-7-server

      If you do not see both rhel-7-server-rpms and rhel-7-server-extras-rpms in the output, or if there is no output, run the following commands to enable each repository:

      # subscription-manager repos --enable=rhel-7-server-rpms

      # subscription-manager repos --enable=rhel-7-server-extras-rpms

   2. Install the required packages.

      # yum install -y policycoreutils container-selinux

   3. Persistently enable container use of the Ceph file system in SELinux.

      # setsebool -P container_use_cephfs on

Procedure

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

   For Vault KV secret engine API, version 1:

   $ vault secrets enable -path=odf kv

   For Vault KV secret engine API, version 2:

   $ 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.

   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.

   $ vault token create -policy=odf -format json

Procedure

1. Log in to the OpenShift Web Console.
2. Click Operators → OperatorHub.
3. Scroll or type OpenShift Data Foundation into the Filter by keyword box to find the OpenShift Data Foundation Operator.
4. Click Install.

5. Set the following options on the Install Operator page:

   1. Update Channel as stable-4.9.
   2. Installation Mode as A specific namespace on the cluster.
   3. Installed Namespace as Operator recommended namespace openshift-storage. If Namespace openshift-storage does not exist, it is created during the operator installation.

   4. Select Approval Strategy as Automatic or Manual.

      If you select Automatic updates, then the Operator Lifecycle Manager (OLM) automatically upgrades the running instance of your Operator without any intervention.

      If you select Manual updates, then the OLM creates an update request. As a cluster administrator, you must then manually approve that update request to update the Operator to a newer version.

   5. Ensure that the Enable option is selected for the Console plugin.
   6. Click Install.

Procedure

1. In the OpenShift Web Console, click Operators → Installed Operators to view all the installed operators.

   Ensure that the Project selected is openshift-storage.

2. Click on the OpenShift Data Foundation operator, and then click Create StorageSystem.

3. In the Backing storage page, select the following:

   1. Select the Use an existing StorageClass option.

   2. Select the Storage Class.

      By default, it is set to gp2.

   3. Expand Advanced and select Full Deployment for the Deployment type option.
   4. Click Next.

4. In the Capacity and nodes page, provide the necessary information:

   1. Select a value for Requested Capacity from the dropdown list. It is set to 2 TiB by default.

      Note

      Once you select the initial storage capacity, cluster expansion is performed only using the selected usable capacity (three times of raw storage).

   2. In the Select Nodes section, select at least three available nodes.

      For cloud platforms with multiple availability zones, ensure that the Nodes are spread across different Locations/availability zones.

      If the nodes selected do not match the OpenShift Data Foundation cluster requirement of an aggregated 30 CPUs and 72 GiB of RAM, a minimal cluster is deployed. For minimum starting node requirements, see the Resource requirements section in the Planning guide.

   3. Click Next.

5. Optional: In the Security and network page, configure the following based on your requirements:

   1. To enable encryption, select Enable data encryption for block and file storage.

   2. Choose either one or both the encryption levels:

      • Cluster-wide encryption

        Encrypts the entire cluster (block and file).

      • StorageClass encryption

        Creates encrypted persistent volume (block only) using encryption enabled storage class.

   3. Select the Connect to an external key management service checkbox. This is optional for cluster-wide encryption.

      1. Key Management Service Provider is set to Vault by default.
      2. Enter Vault Service Name, host Address of Vault server ('https://<hostname or ip>'), Port number and Token.

      3. Expand Advanced Settings to enter additional settings and certificate details based on your Vault configuration:

         1. Enter the Key Value secret path in Backend Path that is dedicated and unique to OpenShift Data Foundation.
         2. Optional: Enter TLS Server Name and Vault Enterprise Namespace.
         3. Upload the respective PEM encoded certificate file to provide the CA Certificate, Client Certificate and Client Private Key .
         4. Click Save.
   4. Click Next.

6. In the Review and create page, review the configuration details.

   To modify any configuration settings, click Back.

7. Click Create StorageSystem.

1. Verify the state of the pods.
2. Verify that the OpenShift Data Foundation cluster is healthy.
3. Verify that the Multicloud Object Gateway is healthy.
4. Verify that the OpenShift Data Foundation specific storage classes exist.

Procedure

1. Log in to the OpenShift Web Console.
2. Click Operators → OperatorHub.
3. Scroll or type OpenShift Data Foundation into the Filter by keyword box to find the OpenShift Data Foundation Operator.
4. Click Install.
