-----------------------------------
Summary: Block Storage: Kubernetes dynamic persistent volume
provisioner
Key: HDFS-13022
URL: https://issues.apache.org/jira/browse/HDFS-13022
Project: Hadoop HDFS
Issue Type: Sub-task
Components: HDFS-7240
Affects Versions: HDFS-7240
Environment: With HDFS-13017 and HDFS-13018 the cblock/jscsi server
could be used in a kubernetes cluster as the backend for iscsi persistent
volumes.
Unfortunatelly we need to create all the required cblocks manually with 'hdfs
cblok -c user volume...' for all the Persistent Volumes.
But it could be handled with a simple optional component. An additional service
could listen on the kubernetes event stream. In case of new
PersistentVolumeClaim (where the storageClassName is cblock) the cblock server
could create cblock in advance AND create the persistent volume could be
created.
The code is very simple, and this additional component could be optional in the
cblock server.
