By default, {product-title} supports CSI inline ephemeral volumes with these limitations: | ||||||
|
||||||
* Support is only available for CSI drivers. In-tree and FlexVolumes are not supported. | ||||||
* The Shared Resource CSI Driver supports using inline ephemeral volumes only to access `Secrets` or `ConfigMaps` across multiple namespaces as a Technology Preview feature. | ||||||

* Community or storage vendors provide other CSI drivers that support these volumes. Follow the installation instructions provided by the CSI driver provider. | ||||||

CSI drivers might not have implemented the inline volume functionality, including `Ephemeral` capacity. For details, see the CSI driver documentation. | ||||||

As a cluster administrator, you can use the Shared Resource CSI Driver in {product-title} to provision inline ephemeral volumes that contain the contents of `Secret` or `ConfigMap` objects. This way, pods and other Kubernetes types that expose volume mounts, and {product-title} Builds can securely use the contents of those objects across potentially any namespace in the cluster. To accomplish this, there are currently two types of shared resources: a `SharedSecret` custom resource for `Secret` objects, and a `SharedConfigMap` custom resource for `ConfigMap` objects. | ||||||
