How to execute commands on AWS Instance using Boto3

Question

Can anyone tell me if we can execute Shell Commands using Boto3 on Launched AWS instance.

I read at few places about \"boto.manage.cmdshell\" but it is deprecated in

I know I am answering to bit old thread. I am not sure even at that time SSM existed. But now you can use SSM send_command from boto3 to run commands directly on ec2 instances. Here is the sample to run PowerShell commands on EC2 instances

import boto3
ssm_client = boto3.client('ssm', region_name="us-west-2") # use region code in which you are working
response = ssm_client.send_command(
             InstanceIds=[
                "i-03########" # use instance id on which you want to execute, even multiple is allowd
                     ],
             DocumentName="AWS-RunPowerShellScript",
             Parameters={
                'commands':[
                     'ipconfig'
                       ]
                   },
             })
command_id = response['Command']['CommandId']
output = ssm_client.get_command_invocation(
      CommandId=command_id,
      InstanceId='i-03######',
    )
print(output)
