Dockerfile-free containerization

Dockerfile-free containerization is a software development approach that automates the creation of container images directly from source code without the developer explicitly writing a Dockerfile.^[skaffold.md] This method is often facilitated by specialized build tools that analyze the source code and dependencies to construct a deployable image automatically.^[skaffold.md]

Implementation

Tools such as Pack enable building a container image from source code without the need for a Dockerfile^[skaffold.md]. This capability is frequently integrated into development pipelines; for example, Skaffold is a tool used to automate the image building process and can be configured to utilize these Dockerfile-free mechanisms for local Kubernetes development^[skaffold.md].
