問題文
A container image built from a definition file behaves the same on a developer laptop and on a server. Which property of the image accounts for this?
選択肢
- The image downloads its dependencies at start time on whichever host happens to run it.
- The image is recompiled on each host to match that host's libraries as part of the install.
- The image includes a complete operating system with its own kernel, which is what removes any dependency on the characteristics of the machine that happens to be running it at the time.
- The image packages the application together with its dependencies, so the same contents are present wherever it runs.
