Why Use Docker as a Developer?

What Is Docker?

What Is Docker?

  • Lightweight, open, secure platform
  • Simplify building, shipping, running apps
  • Shipping container system for code
  • Runs natively on Linux or Windows Server
  • Runs on Windows or Mac Development
  • machines (with a virtual machine)
  • Relies on “images” and “containers”

The Role of Images and Containers

role image


A read-only template composed of layered

filesystems used to share common files and

create Docker container instances.


An isolated and secured shipping container

created from an image that can be run,

started, stopped, moved and deleted.

Docker in Action


  • Docker simplifies building, shipping and running apps
  • Runs natively on Linux and Windows Server
  • Docker is NOT the same as using Virtual Machines
  • Key benefits to Web Developers:-
    • Accelerate developer onboarding
    • Simplify working with multiple apps
    • Consistency between environments
    • Ship faster!

Hooking Your Source Code into a Container

Module Agenda

module agenda3


  • 1. Create a container volume that points to the source code.
  • 2. Add your source code into a custom image that is used to create a container.

The Layered File System

Layers (From a Dessert Perspective)


Images, Containers and File Layers

Containers and Volumes

Docker Volumes

docker valume

What is a Volume?

  • Special type of directory in a container typically referred to as a “data volume”
  • Can be shared and reused among containers
  • Updates to an image won’t affect a data volume
  • Data volumes are persisted even after the container is deleted

Volume Overview

Removing Containers and Volumes

Creating a Docker Managed Volume

docker run -p 8080:3000 nudvar/www node

Docker Controlled Volumes

docker inspect mycontainer

		“Mounts”: [
			“Name”: “d185...86459”,
			“Source”: “/mnt/.../var/Iib/docker/volumes/d185...86459/ data”,
			“Destination”: “/var/www”,
			“Driver”: “local”,
			“RN”: true

Removing Volumes

docker rm -v lastContainer


  • Docker images and containers rely on a “layered file system”
  • Source Code can be hooked to a container using volumes:
    • docker run -v
  • Volumes are persisted on the Docker Host
  • Volumes can be removed using:
    • docker rm -v last Container

Building Custom Images with Dockerfile

Module Agenda

module agenda4

Module Agenda



  • Create a container volume that points to the source code.
  • Add your source code into a custom image that is used to create a container.

Getting Started with Dockerfile

Dockerfile and Images


Dockerfile Overview

dockerfile overview
  • Text file used to build Docker images
  • Contains build instructions
  • Instructions create intermediate image that can be cached to speed up future builds
  • Used with “docker build” command

Key Dockerfile Instructions

key dockerfile

Dockerfile Example

Publishing an Image to Docker Hub

Publishing an Image to Docker Hub

publishing an image


  • Dockerfile is a simple text file with instructions that is used to create an image
  • Each Dockerfile starts with a FROM instruction
  • Custom images are built using:
    • docker build -t /imageName
  • Images can be pushed to Docker Hub

Is There an Easier Way?

easier way

Docker Compose Can Simplify Container Linking



  • Docker containers communicate using link or network functionality
  • The --link switch provides “legacy linking”
  • The --net command-line switch can be used to setup a bridge network
  • Docker Compose can be used to link multiple containers to each other
