Making Docker Work in Your Computer Infrastructure

Here are some best practices for building Docker images

If you use Docker to manage your infrastructure, you need to put time into thinking about how to build it. Here is a quick rundown of the things to keep in mind: Smaller is Better By itself, Docker makes great use of filesystem space. Because each container only holds the changes from the images, a little bit of image bloat doesn’t directly impact the server adversely. However, this doesn’t mean that we shouldn’t worry about bloat at all. Not only should we not waste space without reason, images that are too big cause other problems that you need to be aware of. The most important consideration is attack surface. Every program that you have on your image is a potential Read More ›

Part 4: Docker—An Introduction to Container Orchestration

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 Read More ›

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

Programming

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 Read More ›

Business and Finance, Programming

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 Read More ›

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 Read More ›
