Java CI/CD: From local build to Jenkins Continuous Integration

Matthew Casperson's blog post, published on October 13, 2020, details a comprehensive guide on setting up a Continuous Integration (CI) system using Jenkins, Docker, and Octopus. The post outlines the process of containerizing a Java application with Docker and then configuring Jenkins to manage builds and publish Docker images. Utilizing Jenkins as a central CI server, the guide walks through launching Jenkins in a Docker container, setting up a Jenkins agent for Docker-based builds, and creating a Jenkins pipeline script to automate the building and pushing of Docker images to Docker Hub. By defining a Jenkins project, the process enables automated integration and delivery of code, reducing the need for manual intervention by developers. The post concludes by mentioning the next step in the deployment process: configuring a Kubernetes cluster in AWS, and encourages readers to explore further resources on CI/CD practices.
