Deploying OpenShift Data Foundation using Microsoft Azure

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-4.14.
   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

   Copy to Clipboard Toggle word wrap

   For vault KV secret engine API, version 2:

   $ vault secrets enable -path=odf kv-v2

   Copy to Clipboard Toggle word wrap

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 -

   Copy to Clipboard Toggle word wrap

3. Create a token that matches the above policy:

   $ vault token create -policy=odf -format json

   Copy to Clipboard Toggle word wrap

Procedure

1. Create a service account:

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

   Copy to Clipboard Toggle word wrap

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

   For example:

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

   Copy to Clipboard Toggle word wrap

2. Create clusterrolebindings and clusterroles:

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

   Copy to Clipboard Toggle word wrap

   For example:

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

   Copy to Clipboard Toggle word wrap

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

   Copy to Clipboard Toggle word wrap

   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)

   Copy to Clipboard Toggle word wrap

5. Retrieve the OCP cluster endpoint.

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

   Copy to Clipboard Toggle word wrap

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

   Copy to Clipboard Toggle word wrap

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

   $ vault auth enable kubernetes

   Copy to Clipboard Toggle word wrap

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

   Copy to Clipboard Toggle word wrap
   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"

   Copy to Clipboard Toggle word wrap

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

   For Vault KV secret engine API, version 1:

   $ vault secrets enable -path=odf kv

   Copy to Clipboard Toggle word wrap

   For Vault KV secret engine API, version 2:

   $ vault secrets enable -path=odf kv-v2

   Copy to Clipboard Toggle word wrap

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 -

   Copy to Clipboard Toggle word wrap

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

    Copy to Clipboard Toggle word wrap

    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

    Copy to Clipboard Toggle word wrap

Procedure

   4. Optional [Technology preview]: Select the Add replica-1 pool checkbox to deploy OpenShift Data Foundation with a single replica. This avoids redundant data copies and allows resiliency management on the application level.

      Warning

      Enabling this feature creates a single replica pool without data replication, increasing the risk of data loss, data corruption, and potential system instability if your application does not have its own replication.

      Important

      Single replica deployment is a Technology Preview feature. Technology Preview features are not supported with Red Hat production service level agreements (SLAs) and might not be functionally complete. Red Hat does not recommend using them in production. These features provide early access to upcoming product features, enabling customers to test functionality and provide feedback during the development process.
