ENTRYPOINT [ "python", "./automatic_trigger/script.py" ]

I have used following command to launch the container

docker build -t trigger -p 8080:8080.

Reduce cost of what exactly?

The best way is to have your applications containers separated, i recommend you to use docker-compose

services:
  jenkins:
    image: jenkins/jenkins:lts

  app1:
    image: yourimage

then run docker compose up and you will have to small containers running.
