Buildpacks provide a solution for developers who are tired of writing lengthy Dockerfiles that describe every step required to build a container image. With buildpacks, developers can simply provide their application code, and the buildpacks take care of the rest. By analyzing the code and its dependencies, buildpacks automate the process of creating a fully functional container image that is ready to be deployed on any cloud platform. This saves developers time and effort, allowing them to focus on writing code and delivering value to their customers.
