haproxy and keepalived install and configuration

On API loadbalancer nodes

echo "install haproxy and keepalived service"
apt install -y haproxy keepalived

echo "copy and move haproxy config"
cat /etc/haproxy/haproxy.cfg
cat <<EOT >> /etc/haproxy/haproxy.cfg
listen Stats-Page

This (and related gists) captures how i created my docker swarm architecture. This is intended mostly for my own notes incase i need to re-creeate anything later! As such expect some typos and possibly even an error...

Each major task has its own gist, this is to help with maitainability long term.
