Docker and CI/CD · Middle · Question 30 of 75

What does `exec "$@"` do at the end of an entrypoint script?

✓Correct answer: Replaces the shell with the command, so it becomes PID 1
2Runs the command in the background and exits the script
3Prints every argument passed to the container

Explanation

Entrypoint scripts often prepare config, then hand over. Without exec, the shell stays PID 1 and signals may never reach the app.
