Ansible: Make a new server ready for consumption. Since not everybody uses amazon or api related services for their setup. This assumes you have a new server (just the root password and can still ssh in with it) and want to add it to your pool of servers (read addserver.yml what it does). Just add below .profile to your current homedir where you…

.profile

PBLOC=~/projects/somewhere/addserver.yml
addserver() {
  if [[ -z "$1" ]]; then
    echo "[e] You need to give an IP for this to work. Dont use ssh-agent, since it will have precedence"
  else
    echo "[i] Running setup for new server, be ready to type in your root password"
    echo "[i] Removing and re-adding the known_hosts file"
    ssh-keygen -f "${HOME}/.ssh/known_hosts" -R $1
    ssh-keyscan -t rsa -H $1 >> ~/.ssh/known_hosts
    ansible-playbook ${PBLOC} -u root -i "newserver," --extra-vars="hosts=newserver ansible_ssh_host=$1" -k
    echo "[i] Ssh keys are added, sudoers file change. You can now run your normal playbooks against this server"
  fi
}
