Script needed for ssh key copying to esxi hosts

I am using below shell script for linux machines

#!/bin/bash
for ip in `cat /root/ip`; do
#    ssh-copy-id -i ~/.ssh/id_rsa.pub $ip
sshpass -p "test" ssh-copy-id -i ~/.ssh/id_rsa.pub $ip
done

But for esxi ssh key path is different.

cat ~/.ssh/id_rsa.pub | ssh root@machineip  'cat >> /etc/ssh/keys-root/authorized_keys

Please help in esxi script
