configuration file docker-compose.yml for create new node / slave in jenkins

I am new in this of the docker-compose.yml configurations and I would like to help you first if the implementation of my file is fine, it is to create a node/slave in jenkis through commands and as an aria to recover the .jar file that generate, reading it and enter the value or path in the <secret> field.

  jenkins_server:
    image: "registry.jala.info/devops/jenkins/jenkins:2.107.3-alphine"

      - "5000:5000"
    volumes:

  jenkins_slave:
    image: "registry.jala.info/devops/jenkins/jnlp-slave:3.27.1-alphine"
