It looks like you clean out and store your metal fire pit someplace after each use; there are no ashes in it, you don't have a hole to drain rain water, and the grass under it is green.
Drilling holes will be areas for rust to form. While that is an option, it will quicken end of life as well as let embers fall through.
I suggest you get a fire proof container like a metal coffee can, and place the ash and charcoal in the fire proof container. Starting a fire on a bed of ash with some charcoal from the last fire, makes fire starting much easier. The ash container should always be stored outside away from buildings and anything flammable.
