Wait for a local redis slave, then start your app!

wait_for_redis.bash

!/bin/bash

X="`/opt/redis/redis-3.0.3/src/redis-cli ping`"
echo ${X}

while  [ "${X}" != "PONG" ]; do
        echo "redis slave not yet ready"
        echo "${X}"
        sleep 30
        X="`/opt/redis/redis-3.0.3/src/redis-cli ping`"
done

# then run start script, or call other bash file, etc
