Post CT create script

#!/bin/bash
NUM=$1
if [ x$NUM == x ]; then
  echo "ERROR:container id parameter is mandatory"
  exit 1
fi;

pct exec $NUM -- apt-get --yes install openssh-server
pct exec $NUM -- apt-get --yes install ansible
pct exec $NUM -- mkdir /root/.ssh
pct push $NUM /etc/lxc_push/authorized_keys /root/.ssh/authorized_keys
pct push $NUM /etc/lxc_push/known_hosts /root/.ssh/known_hosts
pct exec $NUM -- chmod 400 /root/.ssh/authorized_keys

There is one thing missing, the new container's public key has to be added to the ansible host.
Log in or use ssh-keyscan.
