Summary: Create customized CSI server for Ozone
Key: HDDS-1382
URL: https://issues.apache.org/jira/browse/HDDS-1382
Project: Hadoop Distributed Data Store
Issue Type: Sub-task
Reporter: Elek, Marton
Assignee: Elek, Marton
CSI (Container Storage Interface) is a vendor neutral storage interface
specification for container orchestrators. CSI support is implemented in YARN,
Kubernetes and Mesos. Implementing a CSI server makes it easy to mount disk
volumes for containers.
See https://github.com/container-storage-interface/spec for more details about
the spec.
Until now we used https://github.com/CTrox/csi-s3 server to support CSI
specification. Using an ozone specific CSI server would have the following
advantages:
* We can provide additional functionalities (as we have access to the internal
Ozone API not just the very generic s3 api).
* Security setup can be synchronized.
* Increased stability
* Simplified deployment (only the minimal set of the components are required
to be installed)
The CSI specification itself is very simple
(https://github.com/container-storage-interface/spec/blob/master/csi.proto) at
least the part which is required for Ozone.
We can use various fuse s3 driver to mount the ozone buckets via s3.
