The TrueNAS Container Storage Provider (CSP) is an API gateway to provide iSCSI block storage provisioning using the HPE CSI Driver for Kubernetes. It allows you to use TrueNAS and FreeNAS to provide persistent storage using iSCSI to Kubernetes.
CSP API endpoints:
The CSP specification in an open specification that supports iSCSI and Fibre Channel protocols.
As of version 2.2.0 of the HPE CSI Driver, these parts of the CSI spec are currently implemented:
PersistentVolumeClaims
and VolumeSnapshots
)Topology is currently not supported by the HPE CSI Driver.
Releases will track the upstream versioning of the HPE CSI Driver for Kubernetes and potential bugfixes in the TrueNAS CSP will be pushed to the same image tag matching the HPE CSI Driver version.
The TrueNAS CSP will track an official release of the HPE CSI Driver for Kubernetes, i.e v2.2.0 and there will be a subsequent release of the TrueNAS CSP v2.2.0. If a patch release of the CSP is needed, the patch position will be incremented by 10. I.e v2.2.10. The last digit will represent the patch version of the CSI driver. The Helm chart is it's own deliverable and has its own semantic versioning.
See INSTALL.
A Makefile is provided to run the CSP in a local docker container, make sure docker is running and issue:
make all run
The CSP is now listening on localhost:8080
Note: When building and testing the CSP locally it will run with debug logging switched on.
There are a few adhoc tests provided. Make sure you have a TrueNAS/FreeNAS appliance configured with:
make test backend=<IP address of management interface on the TrueNAS appliance> password=<API key>
Note: None of the tests are comprehensive nor provide full coverage and should be considered equivalent to "Does the light come on?".
See e2e/README.md how to configure and run Kubernetes e2e test suite focused the CSI tests for the TrueNAS CSP.
These are the known limitations.
