we want to use Ceph but we want to use Docker and Kubernetes to
deploy new instances of Ceph quickly.

I tried to use the default ceph docker hub: ceph/daemon-base. But I didn’t work.

I tried to use the ceph-container. Seems like it doesn’t work.

This is my last deployment file:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: ceph3-deployment
spec:
  replicas: 1
  selector:
    matchLabels:
      app: ceph3
  template:
    metadata:
      labels:
        app: ceph3
    spec:
      containers:
        - name: ceph
          image: ceph/daemon-base:v3.0.5-stable-3.0-luminous-centos-7
          resources:
            limits:
              memory: 512Mi
              cpu: "500m"
            requests:
              memory: 256Mi
              cpu: "250m"
          volumeMounts:
            - mountPath: /etc/ceph
              name: etc-ceph
            - mountPath: /var/lib/ceph
              name: lib-ceph
      volumes:
        - name: etc-ceph
          hostPath:
            path: /etc/ceph
        - name: lib-ceph
          hostPath:
            path: /var/lib/ceph

Does someone already install a ceph instance on Kubernetes?

I tried to follow the tutorial here

But pods not working:
