Dell CSI Extensions

This repository holds definitions of additional grpc protocols which can be implemented by CSI drivers to build upon existing functionality supported via the Container Storage Interface (CSI). These are defined as .proto files, and compiled using the protoc program to generate a go file.

Current set of supported protocols:

• podmon - Extensions to CSI to enable CSI drivers to report host connectivity status
• replication - Extensions to CSI to enable CSI drivers to leverage storage array based replication within Kubernetes clusters
• volumeGroupSnapshot - Extensions to CSI to enable CSI drivers to manage crash-consistent snapshots of groups of volumes

You can utilize the provided Makefile to compile protocol definitions in .proto files to go source files and then build the source files.

• podmon to compile and update files for podmon
• replication to compile and update files for replication.
• volumeGroupSnapshot to compile and update files for volumeGroupSnapshot

Each protocol is available as a go module and can be included separately in CSI drivers.

If you are using gocsi for developing CSI driver, these extensions APIs can be used in CSI drivers by registering additional grpc servers while creating the Storage Plugin object. This facility is available in the forked version of gocsi here.

For using podmon, include "github.com/dell/dell-csi-extensions/podmon" in your go module dependencies.
For using replication, include "github.com/dell/dell-csi-extensions/replication" in your go module dependencies. For using volumeGroupSnapshot, include "github.com/dell/dell-csi-extensions/volumeGroupSnapshot" in your go module dependencies.
