k8s挂载s3fs

github地址：https://github.com/freegroup/kube-s3
DaemonSet的配置 mountPath: /var/s3:shared 在containerd引擎下变成了路径/var/s3:shared
修改mountPath去掉shared, 添加：mountPropagation: Bidirectional
yaml如下：

apiVersion: apps/v1
kind: DaemonSet
metadata:
  labels:
    app: s3-provider
  name: s3-provider
spec:
  selector:
    matchLabels:
      app: s3-provider

            exec:
              command: ["/bin/sh","-c","umount -f /var/s3"]
        securityContext:
          privileged: true
        envFrom:
        - secretRef:
            name: s3-config
        volumeMounts:
        - name: mntdatas3fs
          mountPath: /var/s3
          mountPropagation: Bidirectional
      volumes:

        hostPath:
          path: /mnt/data-s3-fs
