Point parallel cluster onNodeConfigured option to script on locally mounted filesystem

Question

When setting up a parallel cluster, there is an option to mount an EFS file system on head and compute nodes with something like:

SharedStorage:
      - MountDir: /efs
        Name: standard-efs
        StorageType: Efs
        EfsSettings:
          FileSystemId: fs-blah

There is also a way to run an automatic configuration script on head/compute nodes with, e.g.,:

HeadNode:
      CustomActions:
        OnNodeConfigured: script-url

Currently, `script-url` has to start with `s3://` or `https://`. Is there a way to point a head/compute node configuration script to my mounted EFS dir, e.g., to `file://efs/my-node-setup.sh`?

Hi JohnB,

this is currently not possible, as workaround you could use a simple script in s3 that calls the script in the efs storage:

```
HeadNode:
  CustomActions:
    OnNodeConfigured: s3://simple-script.sh
```

content of the simple-script.sh:
```
bash /efs/my-node-setup.sh
```
