echo "Checking for response status ${1} from URL: ${2}"
try_count=0
while true
do
  ((try_count++))
  response_status="$(curl -s -o /dev/null -w "%{http_code}" "${2}")"
  if [ "$response_status" == "${1}" ]
  then
    echo "✅  URL is responding to requests"
    break
  else
    if [ $try_count -gt 59 ]
    then
      echo "❌  URL is not responding to requests, last status: $response_status"
      exit 1
    else
      echo "⏳  request failed: $response_status (retry #$try_count in 10-seconds)"
      sleep 10
      continue
