Part 4: Docker—An Introduction to Container Orchestration

This tutorial will focus on Docker’s swarm because it comes installed with Docker and uses the same standard Docker files

In this installment we are going to look at “container orchestration” for Docker. In the previous installment, we just looked at how to run an individual container. However, most applications are a combination of services which are orchestrated together to make an application. While in theory all the pieces of an application could be built into a single container, it is better to split an application into its relevant services and run a separate container for each service. There are several reasons for this, but the biggest one is scalability. Remember, the containers don’t care if they all run on the same physical machine or different machines. By splitting the services into different containers, we can tell them all to…

Part 3: Working with Docker: An Interactive Tutorial

Docker gives development teams more reliable, repeatable, and testable systems, deployed at massive scale with the click of a button

As businesses move more and more infrastructure online due to the effects of competition (not to mention COVID-19), finding the best way to manage that infrastructure becomes more and more important. Docker gives development teams more reliable, repeatable, and testable systems that can be deployed at massive scale with the click of a button. In this series (Parts 1 and 2 are linked below), we are looking under the hood at Docker, an infrastructure management tool that has grown rapidly in popularity over the last decade. In this installment, I will walk you through the process of using the Docker command line tools to download, install, and run containers, as well as build your own container. If you’re not a…

Part 2: A Peek Under the Covers at the New Docker Technology

Many advances enable Docker to significantly reduce a system’s overhead

As businesses move more and more of their infrastructure online due to the effects of competition (not to mention COVID-19), finding the best way to manage that infrastructure becomes more and more important. As we saw in Part 1, Docker enables development teams to have more reliable, repeatable, and testable systems that can be deployed at massive scale with the click of a button. In this installment, we are going to take a look at the technology behind Docker and how it originated. From Emulators to Virtual Machines Docker allows you to run numerous “containers” at the same time on a single computer. Each of these containers acts as if it were a separate computer. It knows nothing about what…

How the Docker Revolution Will Change Your Programming, Part 1

Since 2013, Docker (an operating system inside your current operating system) has grown rapidly in popularity

As businesses move more and more infrastructure online due to the effects of competition (not to mention COVID-19), finding the best way to manage that infrastructure becomes more and more important. Docker enables development teams to have more reliable, repeatable, and testable systems that can be deployed at massive scale with the click of a button. In this series, we are looking under the hood at Docker, an infrastructure management tool that has rapidly grown in popularity over the last decade. A new infrastructure element has been quietly taking over for managing server-side code deployments. Docker was first released in 2013, and has seen an exponential rise in usage for developer deployments. Over the last seven years, Docker has quietly…
