City platform engineers containerize a Python DNA Center collector. What does using Docker for that application primarily establish?
Select an answer to reveal the explanation.
Short Explanation
The recipe travels with the meal—FROM and app bits define the runtime inside the image so any Docker kitchen can cook it. Installing Python on every VM is the non-container design.
Full Explanation
Containerizing an application means a Dockerfile declares FROM plus the application bits so any Docker host can run that image. Instructing operators to install the language runtime on every VM is the non-container approach. Compose, Helm, and cluster scheduling are outside the core 4.4 image-defined-runtime skill.
