I mainly use two different sized old school Mokka Express aluminum cans from Bialetti. Super cheap (got both for less than 20$) and very small/easy to handle and clean. Plus: the coffee tastes great. I grind my own coffee (cheap used 20yrs old grinder, 4$), but there are sealed ground coffee packs containing only 60 grams (2oz). Coffee is not as instant as with a Keurig/Nespresso though.
