ansible ssh prompt known_hosts issue

Question

I\'m running Ansible playbook and it works fine on one machine.

On a new machine when I try for the first time, I get the following error.

17:04:34          


        

Answer 1

I've created this shell script (also works from Jenkins, btw)

my_known_hosts="$HOME/.ssh/known_hosts"
## housekeeping ##
if [ -f $my_known_hosts".old" ] 
    then rm -f $my_known_hosts".old"
fi
## housekeeping ##
## backup ##
if [ -f $my_known_hosts ] 
    then mv $my_known_hosts "$my_known_hosts.old"
fi
## backup ##
## query aws for active hosts and add to known_hosts
aws ec2 describe-instances --query 'Reservations[*].Instances[*].NetworkInterfaces[*].Association.PublicDnsName' --output text | xargs -L1 ssh-keyscan -H >> $my_known_hosts
## query aws for active hosts and add to known_hosts
