How to check the entry point of an existing container?

To view the entrypoint of an existing Docker container, you can use the command:

docker inspect --format='{{.Config.Entrypoint}}' <container_id_or_name>

This command will display the current entrypoint of the container. If you also want to see the CMD, you can use:

docker inspect --format='Entrypoint: {{.Config.Entrypoint}}, Cmd: {{.Config.Cmd}}' <container_id_or_name>

Alternatively, you can simply run docker inspect <container_id_or_name> and look for the Entrypoint and Cmd fields in the JSON output.
