[4] Użycie „Dockerfile”

24 lipca 2020 Wyłączono przez Adam [zicherka] Nogły
Użyjemy teraz Dockerfile i stworzymy obraz kontenera automatycznie.
Jest możliwe również użycie go jako menadżera kontenerów oraz ich konfiguracji.
[1] Użyjemy teraz Dockerfile, aby stworzyć kontener z zainstalowanym Nginx’em i uruchomimy go.
