Docker + Python

Containerize a Python App in 5 Minutes

Python for better or worse has found cemented itself as the lingua franca of data science. With its rise in popularity also comes how it is deployed. Simultaneously with the rise in Python has also been the rise in container deployments. Like Python, containers are being used in data science as well to run processes…

Containerize a Node App in 5 Minutes

Node and Docker are a match made in heaven because the strengths of Node play to the strengths of Docker. Node microservices typically are built on top of the Express web server which can be configured with “just enough” server and run an application. Additionally, the Node package manager, NPM, makes installing and running Node…

Why “Kubernetes vs. Swarm” is the Wrong Question

Kubernetes is getting a lot of attention these days. The container industry has coalesced around Kubernetes. And for this reason, many people are giving eulogies for Docker Swarm. While Kubernetes is incredibly popular, the dominance of Kubernetes does not imply the death of Swarm. These two systems do have overlap, but they approach a similar…

Developing a Business Case for Containers

Developing a business case for any technology is not always an easy endeavor. In many organizations, CIO’s, CTO’s, and CISO’s will see the value of adopting new technology strategies, however these are harder to sell to others in the C-suite. Those that don’t fully grasp tech see a lot of costs that they don’t understand…

Choosing Between Containers and Virtual Machines

Containers are simple, but harder to explain. Fundamentally, containers are a virtualization technology and they share a lot of common ground with virtual machines, however the biggest difference between the two is where the abstraction occurs. A VM hypervisor exposes a set of virtualized hardware components like a virtual network card, a virtual hard disk,…

Build, Test, and Deploy .NET Apps with Docker

I had the privilege of presenting at the Atlanta Code Camp this year on .NET and Docker. This talk covered some of the low level components that would be used to build out a DevOps pipeline for .NET apps in Docker — everything from building an app, testing and app, and pushing that app through…

Turbocharge WordPress With Docker

If you’ve ever dealt with WordPress, you’ve probably noticed that it’s not the fastest software out of the box. This is not inherently a problem with WordPress, as it is a complex app that runs on a cross platform technology. Performance of WordPress though can be improved with the combined effects of several small tweaks.…

Quick Start for Moby and LinuxKit

Docker has grown wildly in the last few years. It’s gone from a fledgling startup to a billion-dollar company, and now it’s got the attention of the enterprise. A number of changes have happened at Docker too – there’s been a leadership transition as well as Docker giving many of its core components over to…

How to Avoid a Docker Database Disaster

Containers are cool – and everyone and their mother is trying to get on board with them. While many applications are natural fit for containers in many cases, it feels like some applications are forced into containers so vendors can say, “Hey look at me! I do containers too!” This is particularly true of database…

Multi-Stage Builds with Docker

One of the most anticipated announcements in the Docker space when it comes to building images is Multi-Stage builds because of the huge benefits it gives to CI/CD pipelines in DevOps. Before this announcement, building software in a container usually involved creating a container with all the SDK’s and compilers in the container, uploading code…

Migrating Legacy ASP.NET apps to Docker

Many organizations, not wanting to rewrite applications, are figuring out how to take apps and containerize them for the cloud. Older operating systems are either end-of-life or approaching the end-of-life. Likewise, applications are increasingly being migrated to cloud hosts. The need to do this is as pressing as ever and containers offer a simple, viable…
