How to check if Laravel's `sail up` command is finished (if all the containers are healthy) before doing other actions (like migrating a DB and so on) in bash. Concept by @rosiakpiotr execution by me :)

check.sh

#!/bin/bash

check_sail_containers_status() {
	# A bit of delay to not run the function too quickly:
	sleep 2
	
	# Getting current container state:
	local STATUS=$(sudo ./vendor/bin/sail ps | grep starting)

	# Checking if they're healthy:
	if ! [ "$STATUS" == "" ]; then
		# Recursively running the function:
		check_sail_containers_status
	fi
}


# Starting sail in detached mode:
sudo ./vendor/bin/sail up -d

echo -e "\nChecking sail containers state..."

check_sail_containers_status

echo -e "\nAll containers HEALTHY\n"
# Here you can be sure that the containers are healthy and thus you can safely do anything you need with them.
