If you have already created an EFS and you want to mount it in a Kubernetes Pod you have to add the EKS' Security Group to each mount target.
EC2
This example shows how to make a static provisioned EFS persistent volume (PV) mounted inside container with encryption in transit configured:
---
kind: StorageClass
apiVersion: storage.k8s.io/v1
metadata:
name: efs-sc
provisioner: efs.csi.aws.com
mountOptions:
- tls
---
apiVersion: v1
kind: PersistentVolume
metadata:
name: efs-pv
spec:
capacity:
storage: 5Gi
volumeMode: Filesystem
accessModes:
- ReadWriteOnce
persistentVolumeReclaimPolicy: Retain
storageClassName: efs-sc
csi:
driver: efs.csi.aws.com
volumeHandle: fs-03e456ec05d6df74e # Replace with you EFS identifier.
volumeAttributes:
encryptInTransit: "true"
---
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
name: efs-claim
spec:
accessModes:
- ReadWriteOnce
storageClassName: efs-sc
resources:
requests:
storage: 5Gi
---
apiVersion: v1
kind: Pod
metadata:
name: efs-app
spec:
containers:
- name: app
image: centos
command: ["/bin/sh"]
args: ["-c", "while true; do echo $(date -u) >> /data/out.txt; sleep 5; done"]
volumeMounts:
- name: persistent-storage
mountPath: /data
volumes:
- name: persistent-storage
persistentVolumeClaim:
claimName: efs-claim
Fargate
A Pod running on AWS Fargate automatically mounts an Amazon EFS file system without needing the driver installation.
You can't use dynamic provisioning for persistent volumes with Fargate nodes but you can use static provisioning. An example how to use:
---
apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
name: efs-sc
provisioner: efs.csi.aws.com
---
apiVersion: v1
kind: PersistentVolume
metadata:
name: efs-pv
spec:
capacity:
storage: 5Gi
volumeMode: Filesystem
accessModes:
- ReadWriteOnce
storageClassName: efs-sc
persistentVolumeReclaimPolicy: Retain
csi:
driver: efs.csi.aws.com
volumeHandle: fs-03e456ec05d6df74e # Replace with you EFS identifier.
---
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
name: efs-claim
spec:
accessModes:
- ReadWriteOnce
storageClassName: efs-sc
resources:
requests:
storage: 5Gi
---
apiVersion: v1
kind: Pod
metadata:
name: efs-app
spec:
containers:
- name: app
image: centos
command: ["/bin/sh"]
args: ["-c", "while true; do echo $(date -u) >> /data/out.txt; sleep 5; done"]
volumeMounts:
- name: persistent-storage
mountPath: /data
volumes:
- name: persistent-storage
persistentVolumeClaim:
claimName: efs-claim
