After adding to glance, I can instantiate a instance from that image, assign a public ip to it and can log in into the image through ssh with password. But somehow keypair is not inserted into the image so I can not log in to the instance using ssh keys.

We've had great success using http://boxgrinder.org/ for our Red Hat
family image creation including CentOS.

There is also Oz, <https://github.com/clalancette/oz/wiki>,
<https://github.com/rackerjoe/oz-image-build/>, but historically Oz
had a smaller community.

I won't recommend a manual solution, but it would look something like:

create file /etc/rc.d/rc.local
Insert the following into the file:
mkdir -p /root/.ssh
chmod 700 /root/.ssh
curl -f
> /tmp/metadata-key 2>/dev/null
cat /tmp/metadata-key >> /root/.ssh/authorized_keys
chmod 0600 /root/.ssh/authorized_keys
restorecon /root/.ssh/authorized_keys
 rm -f /tmp/metadata-key

Give the file permissions:
chmod +x /etc/rc.d/rc.local

Hope that helps,
