   @feluelle @eladkal  thank you for your efforts. Let me explain the use case in detail.
   Let's say I want to run some task or simple ls command on ec2 instance. I don't keep my ec2 instance always on, I turn it on when needed. So, to run a bash script or some other command first I have to start the instance. Then I have to ssh into the ec2 instance and pass the command as an argument in SSH Operator. After the work is done. I will shut down the ec2 machine.  Now SSH Operator uses connection hook, which takes hostname parameter. (To ssh into the system I need the hostname of the ec2 instance). For AWS ec2 instance hostname is derived dynamically when I start the instance.  So the connection hook has to be updated with the new hostname before using it in SSH Operator. I hope it's bit clear now. 
   
   Let me know if you need more details.  I appreciate your support.
