How to mount host storage /dev/xvda1 from AWS batch

Question

I am using the AWS batch to launch several jobs at a time. I have created a snapshot of a 30G volume and added that to a launch template. I am using this launch template to create a "compute environment". I have also created a corresponding job definition by keeping "volume" and "mount point" empty. Now once a job is launched I would like to mount an attached EBS volume /dev/xvda1 to a local directory (say /storage) inside a container. How do I achieve this? I tried doing the following from inside a container by executing a simple python code:  
      $ mkdir /storage  
      $ sudo mount /dev/xvda1 /storage  
This command creates /storage directory BUT DOES NOT mount it and throws an error "sudo not found". Without sudo it throws an error "permission denied".  
  
How do I mount this volume from inside a container?   
And if volume and mount point options of container properties are helpful then how do I set them if my host volume is /dev/xvda1 and mount directory is /storage?  
  
NOTE: I do not prefer to use AWS CLI for this. I prefer using either boto3 or using python to run shell commands.

Answer

I figured out the answer to this question. Keeping this thread alive just in case someone finds this helpful in the future.   
  
1. I launched an ECS-optimized AMI instance by attaching the EBS volume to it from the snapshot.   
2. Then I created a directory to mount the volume to.   
3. Then I edited /etc/fstab to automount the volume to the desired directory on boot.    
4. Then I shutdown the ecs process.   
5. Then I created a custom AMI from this instance.   
6. I use this custom AMI and specify this in the compute environment.   
7. Then in the job-definition, I set volume and mount point fields as follows:  
          volume -> name = storage_name, source path = /storage  
          mount_point -> container_path = /desired_path, source_path=storage_name (same as given in the volume field)  
  
This makes it ready to have a larger volume ready with the job.
