I am trying to find a solution to make use of the same Amazon EFS for mounting multiple directories in the Kubernetes deployment. Here is my use case
- I have an application named app1 that needs to persist a directory named "/opt/templates" to EFS
- I have another application named app2 that needs to persist a directory named "/var/logs" to EFS
We deploy the applications as a Kubernetes Pod in the Amazon EKS cluster. If i am using the same EFS for both the above mounts, i can see all the files from both the directories "/opt/templates" and "/var/logs" as i am using the same EFS.
How can i solve the problem of using same EFS for both the application without seeing app1 mounted files in app2 directory ? Is it even possible of using the same EFS ID for multiple applications ?
Here is the Kubernetes manifests i used for for one of the application which includes PersistentVolume, PVC and the Deployment
