John Arundel is a consultant and author of Cloud Native DevOps with Kubernetes. We spoke with John on how adopting DevOps destroys walls, builds bridges, and influences company cultures for the better.

Travis CI is one of the most popular hosted Continuous Integration solutions. Most notably, it has made a huge contribution to the developer community by serving the biggest share of open source projects. However in 2019 most new software projects are looking for a solution that can drive the entire Continuous Delivery lifecycle. There’s also […]

Tim Hockin, one of the originators of Kubernetes, is an artist turned engineer. We spoke with Hockin about the state of Kubernetes in 2018, the past and the future of the project and the buzz around it.

Article originally published on The New Stack. The goal of every tech leader is to deliver bug-free products to customers at high velocity. Today’s cloud-native technology can empower engineering teams to iterate, at scale, faster than ever. But teams that don’t also change how they deliver software will struggle to benefit from the agility and […]

In the Developer Interview series, we talk to engineers who use Semaphore and pick their brains about how they work, what wisdom they would like to pass on, and the most challenging problems they’ve faced during developing. This month, we had a chat with Jeffrey Chupp, the Director of Engineering at Dribbble.

This month we had a chat with Avichay Eyal, the man behind Slim.js – the fastest open source […]

Adoption of serverless technology is surely growing, with emerging product companies who built on top of it. One of them is CloudZero, a Semaphore customer, who recently wrote a detailed article about their experience in achieving continuous delivery for their all-serverless system.

Introduction In this tutorial, we’ll be looking at one of the main use cases for test doubles in Elixir: aiding in the interaction between domain logic and impure components that exist over the boundaries of an application. Tests relying on such components are usually brittle, and need to reach out to external resources whose state […]

At Semaphore, for years we’ve been happy to support open source projects with a free continuous integration service. Today we’re increasing the free CI/CD capacity on all open source organizations from 2 to 4 Boxes.

Earlier, we launched Semaphore Boosters, a feature that allows you to automate parallelizing your RSpec and Cucumber tests in a few clicks. The feature has helped many teams to reduce their Rails CI build times by as much as 2 hours in some cases. Initially, the feature was available only to some users. It has […]

This post is adapted from Rails Testing Handbook, a free ebook on building sustainable Rails apps with BDD. In this tutorial, we will guide you through the process of generating a new Rails 5 application, with all the necessary tools to set up a behavior-driven development (BDD) flow. We will set up 5 tools that […]

Introduction This tutorial is the last in a series of tutorials concerning the container orchestration tool, Docker Swarm. In this series, we’ve already seen how to establish a Swarm cluster, schedule services to the cluster’s nodes, make those services consumable from within and outside the cluster, and update and rollback services in-flight. We’ve mainly focused […]

Ruby on Rails was the first major web framework to include automated tests as part of every new project. The effects have been enormously positive. Many developers have learned to write tests well, which in turn helped them get better at design. Experienced developers were drawn by Rails’ focus on productivity and beautiful code. Their […]
