# Wait For Mysql

wait-for-it.sh doing a great job of waiting for different services to become alive, but on #MacOs #docker is binding port on container start, seconds before #mysql is ready to accept connections

This script waits for first successful query from database or exits with non-zero status after timeout.

Don't forget to change `$query` for the actually working one.
