+## Secrets
+The following extension keys are available under `secret` configuration:

+For example, the following configures custom-secret to use mount with private and unshared content.
+Only the current container can use a private volume.

+```yml
+secrets:
+  custom-secret:
+    x-podman.relabel: Z
