+# This is an example inventory file for use with the

+# playbook.
+#
+# To run the playbook, define an overrides file (as shown here)
+# with the required variable settings and pass it as a parameter
+# on the ansible command-line.
+#
+# Example ansible command:
+# ansible-playbook /usr/share/ansible/stx-ansible/playbooks/update_secure_boot_certificate.yml \
+#     -i @my-inventory-file.yml \
+#     --extra-vars "target_list=localhost,subcloud1"
+
+# Use target_list to specify individual subclouds, or a comma-separated
+# list of subclouds such as 'subcloud1,subcloud2'. To target all online
+# subclouds at once, use 'target_list=all_online_subclouds'.
+#
+# To target the system controller or standalone systems, use 'target_list=localhost'.
+#
+all:

+    secure_boot_cert: <base64_cert>
+    key_exchange_key: <base64_key>
+
+  children:
+    # This will be applied to all online subclouds.
+    # Use the example below in hosts to override specific settings for a subcloud, such as passwords.

+        # Sudo password
+        ansible_become_pass: <sysadmin-pwd>
+#      Add a child group, as shown below, if you need individual

+#      Use the hosts section to add the list of hosts.
+#      Use the vars section to override target_group variables,
+#      such as the ssh password.
+#      Note that you can also override multiple hosts at once or
