A container image must always start `/usr/bin/myapp`, but operators should be able to append different arguments at runtime. Which Dockerfile pattern best supports that?

Question

Accepted Answer

B. Use `ENTRYPOINT` for `/usr/bin/myapp` and `CMD` for default arguments. `ENTRYPOINT` defines the executable that always runs, while `CMD` provides default arguments that users can override when starting the container. That combination is the standard pattern when the program itself should remain fixed. `CMD` alone is easier to replace entirely and does not enforce the executable.
