# run az vmss update -h
     --add                                                         : Add an object to a list of

@vivekananth Hi, please note that the parameter passed in by --add is <key=value, string or JSON string>, so the format you should pass in is as follow:

az vmss update -g resouce-group -n vmss-name --add virtualMachineProfile.osProfile.linuxConfiguration.ssh.publicKeys "path"="/home/sshprizmdocadmin/.ssh/authorized_keys" "keyData"="SSH_PUBLIC_KEY"

[vivekananth]

@zhoxing-ms Still getting the same error, Should the "keyData" be secure string as we are passing sshkey ?
