- 3. - co tojest? Docker to narzędzie, które pozwala umieścić aplik ację oraz jej zależności w lekkim , przenośnym, wirtualnym kontenerze - który można uruchomić na prawie każdym serwerze . To gwarantuje, że oprogramowanie będzie zawsze działać tak samo, niezależnie od architektury, systemu i środowiska w którym go uruchomi. 3
