Extending Docker

Chapter 2. Introducing First-party Tools

Docker provides several tools that extend the functionality outside of the core Docker engine. In this chapter, you will walk-through installing, configuring, and running the following tools:

  • Docker Toolbox
  • Docker Machine
  • Docker Swarm
  • Docker Compose

These tools, while not as functional as some of the more advanced ones that we will be working with in the upcoming chapters, will serve as a good introduction to both adding additional functionality to core Docker engine as well as concepts for deploying and orchestrating your containers, which we will be doing more of towards the end of the book.

Docker Toolbox

Before we start to look at how to use the three other tools, we should look at installing them on our local machine. In the previous chapter, we downloaded a script supplied by Docker and piped it through bash to quickly configure the official Docker YUM or APT repository (depending on the operating system you are running) on an already provisioned server, the command we executed was as follows:

curl -sSL https://get.docker.com/ | sh

This is useful if you already have a Linux-based server up and running on one of the many cloud services or locally on virtual machine; however, what if you want to install Docker on a non-Linux operating system such as Mac OSX or Windows?

Tip

Always check the source. It is best practice to check the source of the bash script that you are going to be downloading and installing; in our case, you can check this by going to https://get.docker.com/ in your browser.

Before we look at the tools that Docker provides to do just that, we should answer the...

Docker Machine

So, when you ran the Docker Quickstart Terminal application, it created a bunch of certificates, SSH keys, and configured your user's environment to run Docker. It also launched a virtual machine running Docker.

Developing locally

The Docker Quickstart Terminal application did this using Docker machine, you can check the status of the machine launched by the application by running the following command:

docker-machine active

This will list the names of any active machines, the default machine launched when you first install Docker is called default, if you run:

docker-machine status default

It should tell you that the virtual machine is currently running. Finally, you should be able to SSH into the virtual machine by running the following command:

docker-machine ssh default

You will notice that when you SSH into the virtual machine, it is running the Boot2Docker distribution.

Note

Boot2Docker is an extremely lightweight Linux distribution based on Tiny Core Linux, and its one...

Docker Swarm

Now that we have discussed how to launch individual Docker instances using Docker Machine, let's get a little more adventurous and create a cluster of instances. To do this, Docker ships a tool called Swarm. When deployed, it acts as a scheduler between your Docker client and host Docker instances, deciding where to launch containers based on scheduling rules.

Creating a local cluster

To start off, we are going to be using Docker Machine to create a cluster locally using VirtualBox (https://www.virtualbox.org), which is bundled with Docker Toolbox. To start, we are going to launch a VM to generate a discovery token. To do this, run the following commands:

docker-machine create -d virtualbox discover

Then configure your Docker client to use the newly created local instance:

eval "$(docker-machine env discover)"

You can check that your Docker client is configured to use the discover instance by running docker-machine ls and making sure that discover has a star in the...

Docker Compose

So far in our exploration of the tools that ship with Docker Toolbox, we have been using services which manage our Docker host machines, the final service that we are going to look at in this chapter deals with containers. I am sure that you will agree that so far the tools provided by Docker are quite intuitive, Docker Compose is no different. It start off life as third-party service called Fig and was written by Orchard Labs (the project's original website is still available at http://fig.sh/).

The original project's goal was the following:

"Provide fast, isolated development environments using Docker"

Since Fig became part of Docker, they haven't strayed too far from the original goal:

"Compose is a tool for defining and running multi-container Docker applications. With Compose, you use a Compose file to configure your application's services. Then, using a single command, you create and start all the services from your configuration.&quot...

Summary

In this chapter, we have covered the additional client tools provided by Docker to extend the functionality of your core Docker installation, all of the tools that we have looked at have been designed to slot into your workflow and be as simple as possible to use. In the later chapters, we will be looking at how to expand some of the core functionality of Docker using third-party services. When we do, we will revisit a few of the tools that we have been through in this chapter and look at how they add additional functionality to them.

What is custom duty/charge? Chevron down icon Chevron up icon

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order? Chevron down icon Chevron up icon

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges? Chevron down icon Chevron up icon

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

  • If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
  • Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.
