1. How much does it costs to run small webapp in the cloud?
First you need to make sure , that you have a valid credit card and that IBM accepts it, in the past I did experienced some problems with it, but recently my credit card was approved by IBM, still I wonder why it sometimes an issue(even Oracle did had such problems) if you have valid credit card.
Let’s have a look at Container registry from IBM
If you have only 5GB per month for your container then its free otherwise you will pay 0.07 Euro per Gigabyte and additionally 0.04 Euro for Storage of more then 0.5 GB.
I don’t think that I will max the 5 gb limit with very small container image ;)
