Easy Clustering with Docker Swarm - Designing CI/CD Systems

Building code is sometimes as simple as executing a script. But a full-featured build system requires a lot more supporting infrastructure to handle multiple build requests at the same time, manage compute resources, distribute artifacts, etc. After our last chapter discussing build events, this next iteration in the CI/CD design series covers how to spin-up a container inside Docker Swarm to run a build and test it. What is Docker Swarm When running the Docker engine in Swarm mode your effectively creating a cluster. Continue reading

Effortless Parsing of Build Specifications - Designing CI/CD Systems

Every code repository is different. The execution environment, the framework, the deliverables, or even the linters, all need some sort of customization. Creating a flexible build system requires a mechanism that specifies the steps to follow at different stages of a pipeline.

As the next chapter in the Comprehensive CI/CD Pipeline and System Design series, this article examines which instructions you’ll want to convey to your custom system and how to parse them. The focus is around a common solution, adding a file into the repository’s root directory that’s read by your execution engine when receiving new webhooks.

Comprehensive CI/CD System Design

Continuous integration and delivery is finally becoming a common goal for teams of all sizes. After building a couple of these systems at small and medium scales, I wanted to write down ideas, design choices and lessons learned. This post is the first in a series that explores the design of a custom build system created around common development workflows, using off-the-shelf components where possible. You’ll get an understanding of the basic components, how they interact, and maybe an open source project with example code from which to start your own.

Using Python to Interact with Docker Containers

“You should really be looking at Vagrant” — he said while I struggled with the keyboard, as if pressing the keys harder was going to magically make it work.

I had recently completed a utility — you know, one of those things that slurp in data from some black hole in a distant corner of the universe, marries it with the structure of a different time-space continuum, and magically spawns a pretty visual representation for mere mortals to easily consume — and I was having the hardest time getting all the pieces together for a demo on a laptop running that OS (yes, that one).

My buddy was trying to point me to a system that helps provision virtual machines from a simple configuration file. A solution which was becoming common in application distribution and deployment, as well as a method to standardize development environments.
