Ceph-CSI-Operator Overview

Secure your stack with a hardened Ceph-CSI-Operator image freshly-built by Minimus. Minimus images always include the most up-to-date package version for all packages and dependencies contained in the image.

Ceph-CSI-Operator manages the deployment and lifecycle of the Ceph CSI drivers (RBD, CephFS, and NFS) on Kubernetes through a set of custom resources, replacing manual driver manifests with a declarative, operator-managed workflow.

Try It Out

This guide installs the Ceph-CSI-Operator in a dedicated test or development cluster and deploys an RBD driver instance.

Prerequisites

A running Kubernetes cluster (v1.32 or higher is recommended)
Helm v3 (Installation instructions)
kubectl installed and configured

Step 1: Add Repository to your Local Client

Add the Helm chart to your local Helm client.

helm repo add ceph-csi-operator https://ceph.github.io/ceph-csi-operator/
helm repo update

Step 2: Render the Chart

Render the chart locally with the image overrides to confirm the Minimus image will be deployed:

helm template ceph-csi-operator \
  --set controllerManager.manager.image.repository=reg.mini.dev/ceph-csi-operator \
  --set controllerManager.manager.image.tag=latest \
  ceph-csi-operator/ceph-csi-operator | grep "image:" | sort -u

Step 3: Deploy the Helm Chart

Install the operator into its own namespace:

helm install ceph-csi-operator \
  --set controllerManager.manager.image.repository=reg.mini.dev/ceph-csi-operator \
  --set controllerManager.manager.image.tag=latest \
  --create-namespace --namespace ceph-csi-operator-system \
  ceph-csi-operator/ceph-csi-operator

Step 4: Verify

Wait a minute and check that the operator pod is up and running:

kubectl -n ceph-csi-operator-system get po

Confirm that the Minimus image was deployed:

kubectl -n ceph-csi-operator-system describe pods | grep Image:

Step 5: Create a Driver Resource

Deploy an RBD Driver custom resource to have the operator roll out the RBD CSI driver:

kubectl apply -f - <<EOF
apiVersion: csi.ceph.io/v1
kind: Driver
metadata:
  name: rbd.csi.ceph.com
  namespace: ceph-csi-operator-system
EOF

Confirm the driver pods were created by the operator:

kubectl -n ceph-csi-operator-system get po -l app.kubernetes.io/name=ceph-csi-operator

Clean Up

Uninstall the driver, the chart, and remove the namespace:

kubectl delete driver rbd.csi.ceph.com -n ceph-csi-operator-system
helm uninstall ceph-csi-operator -n ceph-csi-operator-system
kubectl delete ns ceph-csi-operator-system

Technical Considerations

The Ceph-CSI-Operator image provided by Minimus is a slim, security-hardened alternative to the public image. The images are largely interchangeable, with a few differences as noted below.

Ceph-CSI-Operator built by Minimus:

Runs as a non-root user by default for a security-first approach that protects against privilege escalation attacks.
Drill down on the version specification tab to see the default user, listening ports, entrypoint, volumes, environment variables, etc.

The Payoff

A hardened, minimal image that will remain more secure for the long run and accrue vulnerabilities at a slower rate.

See the risk reduction dashboard for a detailed CVE comparison over the past 30 days.
Review the compliance report to see the default hardening and security configurations for the image.
