Deploying OpenShift Data Foundation using Red Hat Virtualization platform

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-4.12.
   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. Enable the Key/Value (KV) backend path in the 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 the users to perform a write or delete operation on the secret:

   echo '
   path "odf/*" {
     capabilities = ["create", "read", "update", "delete", "list"]
   }
   path "sys/mounts" {
   capabilities = ["read"]
   }'| vault policy write odf -

3. Create a token that matches the above policy:

   $ vault token create -policy=odf -format json

Procedure

1. Create a service account:

   $ oc -n openshift-storage create serviceaccount <serviceaccount_name>

   where, <serviceaccount_name> specifies the name of the service account.

   For example:

   $ oc -n openshift-storage create serviceaccount odf-vault-auth

2. Create clusterrolebindings and clusterroles:

   $ oc -n openshift-storage create clusterrolebinding vault-tokenreview-binding --clusterrole=system:auth-delegator --serviceaccount=openshift-storage:_<serviceaccount_name>_

   For example:

   $ oc -n openshift-storage create clusterrolebinding vault-tokenreview-binding --clusterrole=system:auth-delegator --serviceaccount=openshift-storage:odf-vault-auth

3. Create a secret for the serviceaccount token and CA certificate.

   $ cat <<EOF | oc create -f -
   apiVersion: v1
   kind: Secret
   metadata:
     name: odf-vault-auth-token
     namespace: openshift-storage
     annotations:
       kubernetes.io/service-account.name: <serviceaccount_name>
   type: kubernetes.io/service-account-token
   data: {}
   EOF

   where, <serviceaccount_name> is the service account created in the earlier step.

4. Get the token and the CA certificate from the secret.

   $ SA_JWT_TOKEN=$(oc -n openshift-storage get secret odf-vault-auth-token -o jsonpath="{.data['token']}" | base64 --decode; echo)
   $ SA_CA_CRT=$(oc -n openshift-storage get secret odf-vault-auth-token -o jsonpath="{.data['ca\.crt']}" | base64 --decode; echo)

5. Retrieve the OCP cluster endpoint.

   $ OCP_HOST=$(oc config view --minify --flatten -o jsonpath="{.clusters[0].cluster.server}")

6. Fetch the service account issuer:

   $ oc proxy &
   $ proxy_pid=$!
   $ issuer="$( curl --silent http://127.0.0.1:8001/.well-known/openid-configuration | jq -r .issuer)"
   $ kill $proxy_pid

7. Use the information collected in the previous step to setup the Kubernetes authentication method in Vault:

   $ vault auth enable kubernetes

   $ vault write auth/kubernetes/config \
             token_reviewer_jwt="$SA_JWT_TOKEN" \
             kubernetes_host="$OCP_HOST" \
             kubernetes_ca_cert="$SA_CA_CRT" \
             issuer="$issuer"

   Important

   To configure the Kubernetes authentication method in Vault when the issuer is empty:

   $ vault write auth/kubernetes/config \
             token_reviewer_jwt="$SA_JWT_TOKEN" \
             kubernetes_host="$OCP_HOST" \
             kubernetes_ca_cert="$SA_CA_CRT"

8. 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

9. Create a policy to restrict the users to perform a write or delete operation on the secret:

   echo '
   path "odf/*" {
     capabilities = ["create", "read", "update", "delete", "list"]
   }
   path "sys/mounts" {
   capabilities = ["read"]
   }'| vault policy write odf -

10. Generate the roles:

    $ vault write auth/kubernetes/role/odf-rook-ceph-op \
            bound_service_account_names=rook-ceph-system,rook-ceph-osd,noobaa \
            bound_service_account_namespaces=openshift-storage \
            policies=odf \
            ttl=1440h

    The role odf-rook-ceph-op is later used while you configure the KMS connection details during the creation of the storage system.

    $ vault write auth/kubernetes/role/odf-rook-ceph-osd \
            bound_service_account_names=rook-ceph-osd \
            bound_service_account_namespaces=openshift-storage \
            policies=odf \
            ttl=1440h

      • Disks on selected nodes to use the available disks that match the selected filters only on selected nodes.

        Important

        • The flexible scaling feature is enabled only when the storage cluster that you created with 3 or more nodes are spread across fewer than the minimum requirement of 3 availability zones.

          For information about flexible scaling, see knowledgebase article on Scaling OpenShift Data Foundation cluster using YAML when flexible scaling is enabled.

        • Flexible scaling features get enabled at the time of deployment and can not be enabled or disabled later on.

        • 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 Resource requirements section in Planning guide.
