TDD for infrastructure with Vagrant

Introduction For many years (almost decades) developers have been practicing test driven development and write tests to get confidence that their code works. However, with the rise of infrastructure as code where DevOps engineers try to describe infrastructure provisioning using code, this is something that is not observed generally. Continue reading

Google Container Tools - Jib

With this post we close the series of articles taking a deep dive on building Docker images. We look at a building Docker images for running Java applications in a Docker container with Jib which is part of the Google Container Tools. Continue reading

Docker BuildKit

In the previous blog post of the building docker images series we had a look at Docker image build pipelines. We revealed typical problems and looked at how to overcome some by utilizing multistage builds. In part 4 of this series we work with an addition to the Docker tooling which is BuildKit. Continue reading

Docker image build pipeline

Let’s recap what we have covered in this blog post series so far. In Building a Docker Image we had a look at the anatomy of a Docker image. And Optimizing a Docker Image shed some light on optimizations when building an image. Continue reading

Optimizing a Docker Image

This post continues where we left off with Building a Docker Image. We are looking into how we can optimize the process of building a Docker image. This optimization can aim at reducing the size of images built or the time it takes for packaging an image. Continue reading

Building a Docker Image

This post starts a series of articles taking a deep dive on building Docker images. But before we look at building a Docker image let’s briefly recap the essentials we need to know about container images. A Docker image is built up from a series of layers where each layer represents an instruction in the image’s Dockerfile. Continue reading

Continuous delivery infrastructure as code

This is part 1 of a series of posts covering Docker in a Continuous Delivery environment. Today I’m showing how simple it is to setup a continuous delivery build pipeline infrastructure using Docker. In an upcoming post we will look at Jenkins pipeline as code creating Docker images and running integration tests against Docker containers. Continue reading
