Source-to-Image (S2I) is a Go toolkit and CLI for building reproducible container images directly from source code without writing a Dockerfile. It injects source into builder images that assemble ready-to-run images, supporting multi-step builds for compiled languages.

Use cases

• build a container image from a git repo without a Dockerfile
• create reusable builder images for my team's build environments
• build slim runtime images by compiling in one image and copying artifacts to another
• reproduce the same build environment across CI and local development
• turn a Python or Node app repo into a runnable docker image in one command

When to choose

• you use OpenShift or want Dockerfile-less reproducible image builds
• you want to version and share standardized build environments as builder images
• you need multi-stage builds for compiled languages with slim runtime images

When to avoid

• you prefer explicit Dockerfiles and full control over build steps
• your stack is already well served by Docker multi-stage builds or BuildKit
• you need general-purpose CI pipelines beyond image building
