Dockerize Node.js apps with Buildpacks

Docker is a widely-used tool for creating distributable and deployable artifacts, supporting code from multiple languages and cloud platforms. However, building Docker images, especially for custom applications, can be inefficient and resource-intensive. Cloud Native Buildpacks provide a solution by leveraging industry best practices to build Docker images more efficiently, often requiring no additional configuration. A basic tutorial demonstrates building a Docker image for a simple Node.js application, highlighting inefficiencies in traditional methods and how Buildpacks address these by reusing dependencies through Docker volumes. Buildpacks simplify the process by abstracting complex Dockerfile commands and utilizing advanced features to prevent unnecessary downloads, allowing for quick and efficient image builds with minimal input.
