Niels de Vos 62ec2171e7 ci: use ceph-csi-bot for Mergify actions 
The `bot_account` option was not part of the Open Source plan, but now
it is. When Mergify rebases PRs, it sometimes leaves the following
message:

```
This pull request got rebased on behalf of a random user of the
organization. This behavior will change on the 1st February 2023,
Mergify will pick the author of the pull request instead.

To get the future behavior now, you can configure bot_account options
(e.g.: bot_account: { author } or update_bot_account: { author }.

Or you can create a dedicated github account for squash and rebase
operations, and use it in different bot_account options.
```

It is clearer for everyone when the Ceph-CSI Bot is used for automated
actions. Contributers might get confused why the PR was updated in their
name, without them doing anything.

Ceph CSI

GitHub release Mergify Status Go Report Card TODOs CII Best Practices

This repo contains the Ceph Container Storage Interface (CSI) driver for RBD, CephFS and Kubernetes sidecar deployment YAMLs to support CSI functionality: provisioner, attacher, resizer, driver-registrar and snapshotter.

Overview

Ceph CSI plugins implement an interface between a CSI-enabled Container Orchestrator (CO) and Ceph clusters. They enable 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 the 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 in Kubernetes environments.

Ceph CSI Version Container Orchestrator Name Version Tested
v3.7.2 Kubernetes v1.22, v1.23, v1.24
v3.7.1 Kubernetes v1.22, v1.23, v1.24
v3.7.0 Kubernetes v1.22, v1.23, v1.24
v3.6.1 Kubernetes v1.21, v1.22, v1.23
v3.6.0 Kubernetes v1.21, v1.22, v1.23

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

NOTE:

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

For example, if the Ceph CSI latest major version is 3.7.0 today, support is provided for the versions above 3.6.0. If users are running an unsupported Ceph CSI version, they will be asked to upgrade when requesting support.
