Example: Use an EFS file system as a shared home directory for AWS PCS

Provide this script as the value of "userData" in your launch template. For more information, see Working with Amazon EC2 user data.

This example extends the example EFS mount in Using network file systems with AWS PCS to implement a shared home directory. The contents of /home are backed up before the EFS file system is mounted. The contents are then quickly copied into place on the shared storage after the mount completes.

Replace the following values in this script with your own details:

  • /mount-point-directory – The path on an instance where you want to mount the EFS file system.

  • filesystem-id – The file system ID for the EFS file system.
