Continuous Deployment with Phoenix 1.0 via Semaphore

Josh Adams discusses setting up Continuous Integration (CI) and Continuous Deployment (CD) for a Phoenix-based Elixir application using Semaphore, highlighting its ease of use for both open-source and private projects. The application, hosted on GitHub, features a React-based frontend and uses Phoenix Channels for real-time updates, particularly through an ImageTweetStreamer component that streams and stores tweets with images. Adams emphasizes the importance of automated testing and CI to maintain code quality, noting that Semaphore simplifies the CI setup process significantly compared to traditional infrastructure like Jenkins. He also describes how Semaphore facilitates CD to Heroku, enabling automated deployments from the master branch, which enhances software quality by encouraging developers to be cautious about what they merge. The article conveys Adams's journey from manual to automated deployment, showcasing Semaphore's user-friendly interface that democratizes access to robust CI/CD setups without the need for extensive infrastructure expertise.
