Build an OpenStack install on several bare metal machines.

Variables common amongst all hosts in the cluster

Helper to launch containers

function run_bm {

For some reason container names with periods can cause issues :/

    CONTAINER=$1 CONTAINER_IP=$2 CONTAINER_NETMASK=$NETMASK CONTAINER_GATEWAY=$GATEWAY NAMESERVER=$NAMESERVER TERMINATE=$TERMINATE STACKSH_PARAMS="$COMMON_VARS $3" ./tools/build_bm.sh
}

Launch the head node - headnode uses a non-ip domain name, because rabbit won't launch with an ip addr hostname :(

run_bm STACKMASTER $HEAD_HOST "ENABLED_SERVICES=g-api,g-reg,key,n-api,n-sch,n-vnc,horizon,mysql,rabbit"

Wait till the head node is up

if [ ! "$TERMINATE" = "1" ]; then
    echo "Waiting for head node ($HEAD_HOST) to start..."
    if ! timeout 60 sh -c "while ! wget -q -O- http://$HEAD_HOST | grep -q username; do sleep 1; done"; then
      echo "Head node did not start"
      exit 1
    fi
fi

PIDS=""

Launch the compute hosts in parallel

for compute_host in ${COMPUTE_HOSTS//,/ }; do
    run_bm $compute_host $compute_host "ENABLED_SERVICES=n-cpu,n-net,n-api" &
    PIDS="$PIDS $!"
done

for x in $PIDS; do
    wait $x
done
echo "build_bm_multi complete"
