Docker: What are the steps that need to execute to run an application in docker container ?

Question

I have one application which is running in a stand alone system. I want to run the same application in a docker container. I also want to know that is only one process that can run in a docker container ?

Answer 1

Writing a Dockerfile for a simple Java application:

Let’s create a Dockerfile for the Oracle JDK, which is not available on Docker Hub. To begin this process, create a new folder and then create a file in it named “Dockerfile” with the following content.

# Dockerfile

FROM  phusion/baseimage:0.9.17

MAINTAINER  Author Name <author@email.com>

1. Update the package repository

RUN echo "deb http://archive.ubuntu.com/ubuntu trusty main universe" > /etc/apt/sources.list
RUN apt-get -y update
