I wonder whether the previous hostname was associated with the
instance name or not. If yes, then your cloud-init worked, just that
metadata was not updated by changing the instance name. If no, you
need cloud-init built in the image and it will poll the metadata
after reboot.<div><div class="h5"><br>

<div dir="ltr">is there any way to change hostname
by changing instance name.
<div>I tried changing instance name and then did a
hard reboot but hostname is still the same.If
this is not the right approach for changing
hostname can some one tell me what should be
done to change hostname of instances without
logging to instance.</div>
