I didn't quite understand the copy-on-write section with the coloured boxes. Do different developers have copies of the same container running on their individual machines? Or are they somehow running the same container on their individual machines and then when each developer makes a change it only keeps track of the differences (which are the coloured boxes)?

screw disk space in regards of the layers.. I guess memory would be a far bigger concern

[kirillkruglov]

Great explanation, thanks!
Containers are the individual atomic elements (like nginx, msql, python) or the entire images run by docker?
