amazon ec2 - How to set up a Chef Node on an ec2 instance? -

i trying use knife bootstrap command mac terminal "knife bootstrap node_domain_or_ip -x username -p password -n name_for_node --sudo"

but problem is, don't have user name , password, instead ec2-user has private key stored in local work station helps me connect server. find lot of examples debian os, hard find rhel on ec2.

os: rhel 6 chef: 11.1.6

kindly let me know if details need me better.

even host keys have username. typically, if using

ssh -i somekey user@host_or_ip

to ssh node, use

knife bootstrap node_domain_or_ip -x username -i samekey -n chef_name_you_want --sudo

notice, use -i rather -p. that's there it.

an better option people use knife ec2 server create create node in first place. create node in aws , bootstrap it, in 1 command.
