The article explores the integration of Docker with Bazel, emphasizing how the combination enhances scalability and efficiency in software development. Bazel, a versatile open-source build and test tool originally developed by Google, supports multiple programming languages and environments, and its rules_docker package simplifies Docker-related tasks by eliminating the need for manual Docker commands. The tutorial guides readers through setting up a sample project, creating a Bazel workspace and BUILD files, and utilizing Docker images as part of the Bazel build process, ultimately pushing the built images to Docker Hub. While Bazel offers powerful capabilities for managing containerized builds, it can be complex for smaller projects, prompting the introduction of Earthly as a simpler alternative for building monorepos and containerization. The article concludes by encouraging developers to choose a tool that suits their current and future needs, ensuring a more streamlined and efficient development process.
