Benoît Knecht 0ec6e10bf2 util: Limit cryptsetup PBKDF memory usage 
By default, `cryptsetup luksFormat` uses Argon2i as Password-Based Key
Derivation Function (PBKDF), which not only has a CPU cost, but also a memory
cost (to make brute-force attacks harder).

The memory cost is based on the available system memory by default, which in
the context of Ceph CSI can be a problem for two reasons:

1. Pods can have a memory limit (much lower that the memory available on the
   node, usually) which isn't taken into account by `cryptsetup`, so it can get
   OOM-killed when formating a new volume;
2. The amount of memory that was used during `cryptsetup luksFormat` will then
   be needed for `cryptsetup luksOpen`, so if the volume was formated on a node
   with a lot of memory, but then needs to be opened on a different node with
   less memory, `cryptsetup` will get OOM-killed.

This commit sets the PBKDF memory limit to a fixed value to ensure consistent
memory usage regardless of the specifications of the nodes where the volume
happens to be formatted in the first place.

The limit is set to a relatively low value (32 MiB) so that the `csi-rbdplugin`
container in the `nodeplugin` pod doesn't require an extravagantly high memory
limit in order to format/open volumes (particularly with operations happening
in parallel), while at the same time not being so low as to render it
completely pointless.

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
v3.8.0 Kubernetes v1.24, v1.25, v1.26
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

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