Mount EBS volume to a running AWS instance with a script

I'd like to dynamically mount and unmount an EBS volumes to a running AWS instance using a script and was wondering whether this is achievable, both on linux and windows instances, and if so, what is the expected duration of such operation.

Using AWS CLI and Bourne shell script.

attach-volume

Attaches an EBS volume to a running or stopped instance and exposes it to the instance with the specified device name.

aws ec2 attach-volume --volume-id vol-1234567890abcdef0 --instance-id i-01474ef662b89480 --device /dev/sdf

detach-volume

Detaches an EBS volume from an instance. Make sure to unmount any file systems on the device within your operating system before detaching the volume.

aws ec2 detach-volume --volume-id vol-1234567890abcdef0

--------------------------------------------------------------------------

Use Python and Boto3 which has APIs to attach and detach volumes.

attach_volume

Attaches an EBS volume to a running or stopped instance and exposes it to the instance with the specified device name.

import boto3

client = boto3.client('ec2')
response = client.attach_volume(
    DryRun=True|False,
    VolumeId='string',
    InstanceId='string',
    Device='string'
)

detach_volume

Detaches an EBS volume from an instance. Make sure to unmount any file systems on the device within your operating system before detaching the volume.

response = client.detach_volume(
    DryRun=True|False,
    VolumeId='string',
    InstanceId='string',
    Device='string',
    Force=True|False
)
