Dockerfile for multiple Docker containers

I am working with Docker and I have a web-app that requires the following:

  1. Tomcat
  2. PostgresSQL
  3. MongoDB

To install item 2 and 3 I do the following:

  • Passing command line arguments through the Remote API
  • Easiest way to deploy docker application
  • How to save node-red console logs into a separate log file within docker
  • Docker image push over SSH (distributed)
  • How do links and scaling work together in docker compose?
  • How to configure CouchDB authentication in Docker?
  • I can run a command for PostgresSQL like :

    docker run --name some-postgres -e POSTGRES_PASSWORD=mysecretpassword -d postgres

    For Mongodb I run:

    docker run --name some-mongo -d mongo

    For Tomcat, I have a Dockerfile with Tomcat and copying my war to the apps folder. I build the image using Docker and run it.

    My question is whether there is a better way to coordinate this step by step via separate script? Is Docker compose the solution for this?


  • Is there any method I can modify the “IP” address without removing the docker container?
  • How can I run docker-compose up as shell script by Jenkins
  • Could not run mvc 6 on Docker
  • Start a service in docker container failed,with error: Failed to get D-Bus connection: No connection to service manager

    A Dockerfile is a recipe for building an image, which is a template for starting containers. To describe a system that is made of multiple containers using standardized images, you would use docker-compose, not a new Dockerfile. You would use a Dockerfile to customize a pre-existing docker image, like mysql or node or ubuntu, for some specific use.

    docker-compose allows you to express multiple docker commands as a .yml file in a specific format.

    You can then use docker-compose up to start the set of containers.

    The docker-compose .yml file for your example might start looking somewhat like this

        image: postgres
        image: mongo

    You would add links between the containers with a links: line. These and other details are in the docs.

    Basically docker-compose is just a yaml file implementation of docker run.
    As docker run has arguments passed to it, these exact same arguments are stipulated in docker compose in a yaml format instead of on the command line.
    Docker compose supports multiple containers too.

    Docker compose has a few other nice features such as docker-compose logs , this command gives logs of all containers started by compose.

    Docker will be the best open platform for developers and sysadmins to build, ship, and run distributed applications.
