Is there any way to find out how much RAM each of my dockers is using?   Unlike VM which I assign a fix amount of RAM, I have no idea how much RAM I need to reserve for dockers.   So for example, crashplan says officially it requires 1GB per 1TB data. However, I read a review saying it's more like 500MB for 90GB. I have 1.5TB => projecting to about 8GB of RAM.
