Description

One of the major challenges while creating an application is adapting your application to run smoothly on all of the plethora of operating systems available. Docker is an extremely efficient technology that allows you to wrap all your code along with its supporting files into a single bundle; it also guarantees that your application will behave in the same way on any host powered by Docker. You can also easily reuse existing Docker containers or create and publish your own. Unlike Virtual Machines, Docker containers are lightweight and more efficient.

Beginning Docker starts with the fundamentals of Docker—explaining how it works, how to set it up, and how to get started on leveraging the benefits of this technology. The course goes on to cover more advanced features and shows you how to create and share your own Docker images.

You will learn how to install Docker on your own machine, then how to manage it effectively, and then progress to creating and publishing your very own application. You will then learn a bit more about Docker Containers; built-in features and commands such as volumes, mounts, ports, and linking and constraining containers; before diving into running a web application.

Docker has functionality such as the Docker web API to handle complex automation processes which will be explained in detail. You will also learn how to use the Docker Hub to fetch and share containers, before running through the creation of your own Docker powered mini-Heroku

Beginning Docker covers everything required to get you up and running with Docker, with detailed real-world examples and helpful tips to make sure you get the most from it.

Introduction
4 Lectures 15:15

This video will offer an overview of the course.

Preview 02:54

See how to get your own Docker running using a local virtual machine that is controlled by Vagrant.

Getting Docker Inside a Vagrant VM
03:31

Learn the difference between Docker containers and traditional virtual machines.

Containers Versus Virtual Machines
04:43

Get a high-level overview of the objects Docker works with and how they are used.

How Docker Works?
04:07

Docker Basics
5 Lectures 23:03

We have Docker and want to run a command in an isolated container, so we use "docker run" to work with commands in containers.

Preview 06:07

You want to manage containers once you've started creating them. You can list, inspect, view log, stop, and delete them with basic Docker commands.

Managing Your Containers
05:21

We want to make an image that has a package (sshd) already installed and configured. So, we'll use Docker commands to make a new image from an existing image.

Committing Changes to a Container Image
04:35

Once you've made a container you like, you would want to share it with others or make it easy for you to install on other machines. So, you have to push the container image to the Docker index.

Sharing a Container on the Index
03:19

Making containers for everything we want to use in containers is difficult, so we can use ready-made containers. Find and use container images using the Docker index and the Docker ecosystem.

Finding and Using Third-party Containers
03:41
+
Building Containers
5 Lectures 16:29

We want to quickly and consistently produce and reproduce a container image, so we use a Dockerfile to define a container.

Preview 03:37

We are making an image that uses a versioned configuration file, so we can add it to the container in the build process.

Adding Files to Your Container
02:42

We want to simplify the running process of our container, so we add metadata and defaults to the Dockerfile.

Setting Default Container Properties
04:23

You have a container that you want to use but with some variations, so you will build a new container based on the existing image.

Building on Existing Containers
02:26

We want others to trust our image in the Docker index, so we will set up trusted builds to automatically build from our GitHub repository.

Setting Up Trusted Builds
03:21
+
More Docker Features
5 Lectures 18:37

Using the Docker run command to improve performance, and exploring some of the features it provides us when running containerized commands.

Preview 04:23

Discover how to use docker run to override some of the defaults that come with containers, which are usually specified from their Dockerfiles.

Overriding the Dockerfile Defaults
03:16

Learn about Docker volumes and mounts and how we can use docker run to configure them for our containers.

Using Volumes and Mounts
03:40

Learn about ports and networking with Docker and Docker Containers.

Ports and Networking
04:05

Similar to how we can"share" data volumes across containers, we can also "share" ports across containers so that they can communicate with each other.

Linking Containers
03:13
+
Running a Web Application with Docker
5 Lectures 17:34

Although Docker is great for running backing services and infrastructure, its real value comes from shipping your application. Unlike the supporting infrastructure, your application will be updated and shipped quite frequently. Docker can make this process much easier. In order to demonstrate this, we’re going to build a simple web application to deploy with Docker.

Preview 03:02

Previously, we made a simple "Hello World" web application that uses Redis to increment a counter with every request. Now, we’re going to take this application and "Dockerize" it.

Containerizing the Application
02:25

Work through the process that is required to set up an application server to act as our production server to deploy on.

Setting Up an Application Server
02:59

Demonstrate how to effectively ship a container to another machine.

Shipping the Container to Production
03:56

We show how we can streamline the process and create an easy deployment workflow.

Creating a Simple Deployment Workflow
05:12
+
Basic Docker Automation
5 Lectures 24:00

We will explore the idea of automation in Docker.

Preview 06:57

Demonstrate how we can expose control of containers to other containers.

Container Inside a Container
02:46

Explain the limitations of the in-built logging functionality.

Managing Docker Logs with logspout
05:17

Building our own Docker-powered mini-Heroku platform-as-a-service using Dokku.

Creating Your Own PaaS with Dokku
04:53

Explore Docker pattern called ambassador.

Using Ambassador Containers
