+During installation, your cloud credentials are sufficient to create Azure Blob
+Storage, and the Registry Operator automatically configures storage.
+
+.Prerequisites
+
+* A cluster on Azure with user-provisioned infrastructure in a government region.
+* To configure registry storage for Azure, provide Registry Operator
+cloud credentials.
+* For Azure storage, the secret is expected to contain one key:
+** `REGISTRY_STORAGE_AZURE_ACCOUNTKEY`
+
+.Procedure
+
+. Create an link:https://docs.microsoft.com/en-us/azure/storage/blobs/storage-quickstart-blobs-portal[Azure storage container].
+
+. Fill in the storage configuration in `configs.imageregistry.operator.openshift.io/cluster`:
++
+[source,terminal]
+----
+$ oc edit configs.imageregistry.operator.openshift.io/cluster
+----
++
+.Example configuration
+[source,yaml]
+----
+storage:
+  azure:
+    accountName: <storage-account-name>
+    container: <container-name>
+    cloudName: AzureUSGovernmentCloud <1>

You can also set `cloudName` to `AzureUSGovernmentCloud`, `AzureChinaCloud`, or `AzureGermanCloud` with sufficient credentials.
