Mount GCS Fuse without privileges in K8s/GKE

You can now use GCS fuse for GKE which doesn't require privileged pods: https://cloud.google.com/kubernetes-engine/docs/how-to/persistent-volumes/cloud-storage-fuse-csi-driver

OLD ARCHICED! Only use for non GCS use cases below:

All credit should go to @pre: kubernetes/kubernetes#7890 (comment)

Creating a Device Manager that allows sharing /dev/fuse to containers

Create the ConfigMap for the DeviceManager:

kubectl apply -f device-manager-cm.yaml

Create the device manager DaemonSet:

kubectl apply -f device-manager-ds.yaml

Configure AppArmor to allow mounting fuse

Create a namespace for the AppArmor loader:

kubectl apply -f apparmor-ns.yaml

Create the ConfigMap that contains our AppArmor policy:

kubectl apply -f apparmor-cm.yaml

Create DaemonSet that runs AppArmor loader on each node:

kubectl apply -f apparmor-ds.yaml

Mount fuse from a pod

Create a deployment that specifies our custom AppArmor policy

kubectl apply -f app-that-mounts-fuse.yaml

Now test by running in the fuser-mounter pod

kubectl exec -ti deployment/fuse-mounter -- bash
gcsfuse your-gcs-bucket3 /mnt
