Humble Chirammal b49bf4b987 rbd: parse migration secret and set it for controller server operations 
This commit adds a couple of helper functions to parse the migration
request secret and set it for further csi driver operations.

More details:

The intree secret has a data field called "key" which is the base64
admin secret key. The ceph CSI driver currently expect the secret to
contain data field "UserKey" for the equivalant. The CSI driver also
expect the "UserID" field which is not available in the in-tree secret
by deafult. This missing userID will be filled (if the username differ
than 'admin') in the migration secret as 'adminId' field in the
migration request, this commit adds the logic to parse this migration
secret as below:

"key" field value will be picked up from the migraion secret to "UserKey"
field.
"adminId" field value will be picked up from the migration secret to "UserID"
field

if `adminId` field is nil or not set, `UserID` field will be filled with
default value ie `admin`.The above logic get activated only when the secret
is a migration secret, otherwise skipped to the normal workflow as we have
today.

Ceph CSI

GitHub release Go Report Card TODOs

This repo contains Ceph Container Storage Interface (CSI) driver for RBD, CephFS and kubernetes sidecar deployment yamls of provisioner, attacher, resizer, driver-registrar and snapshotter for supporting CSI functionalities.

Overview

Ceph CSI plugins implement an interface between CSI enabled Container Orchestrator (CO) and Ceph cluster. It allows dynamically provisioning Ceph volumes and attaching them to workloads.

Independent CSI plugins are provided to support RBD and CephFS backed volumes,

  • For details about configuration and deployment of RBD plugin, please refer rbd doc and for CephFS plugin configuration and deployment please refer cephFS doc.
  • For example usage of RBD and CephFS CSI plugins, see examples in examples/.
  • Stale resource cleanup, please refer cleanup doc.

NOTE:

  • Ceph CSI Arm64 support is experimental.

Project status

Status: GA

Known to work CO platforms

Ceph CSI drivers are currently developed and tested exclusively on Kubernetes environments.

Ceph CSI Version Container Orchestrator Name Version Tested
v3.4.0 Kubernetes v1.20, v1.21, v1.22
v3.3.0 Kubernetes v1.20, v1.21, v1.22

There is work in progress to make this CO independent and thus support other orchestration environments (Nomad, Mesos..etc) in the future.

NOTE:

The supported window of Ceph CSI versions is known as "N.(x-1)": (N (Latest major release) . (x (Latest minor release) - 1)).

For example, if Ceph CSI latest major version is 3.4.0 today, support is provided for the versions above 3.3.0. If users are running an unsupported Ceph CSI version, they will be asked to upgrade when requesting support for the cluster.
