Your jars don't necessarily need to be sterilized because these will be kept in the fridge. If you are going to make a lot and want to keep them in the cupboard they won't be very crisp but they will still be delicious. Also, you need to follow all the regular canning processes of sterilizing jars and processing in a hot water bath. You might want to consider keeping your cucumbers in an ice bath for 1-2 hours to help them stay crispy.
