Answer
ENTRYPOINT defines the main command a container runs automatically, giving it a predictable default behavior.
Quick Answer
ENTRYPOINT sets the main executable that always runs when the container starts. It defines the container's purpose — like setting it to run nginx or a Python script. CMD provides default arguments to ENTRYPOINT, but they can be overridden at runtime. ENTRYPOINT is the fixed behavior; CMD is the flexible part.
