entrypoint

In Dockerfiles, `CMD` and `ENTRYPOINT` define the commands a container runs. `CMD` sets default commands or arguments, easily overridden by `docker run`. `ENTRYPOINT` ensures a specific command always runs, with arguments passed via `CMD` or `docker run`. Combining both offers flexibility and control. Advanced examples include using environment variables, multi-stage builds, and web servers. Understanding their differences and use cases helps create robust, adaptable Docker images for various applications.
