Kubernetes image builder

This tool enables systematic creation of Kubernetes-ready container images through a defined build plan and OCI-compliant outputs. It accepts a base image, target Kubernetes version, registry details, and image identifiers, then derives a reproducible multi-stage build plan. Conceptually, it separates concerns into base image provisioning, artifact compilation, and final image assembly, followed by a multi-arch manifest generation for AMD64 and ARM64. Users benefit from consistent tagging, predictable image sizes, and registry-compatible artifacts that align with Kubernetes deployment policies. Core value lies in reproducibility, cross-cluster consistency, and automation-friendly outputs that fit into CI/CD pipelines. Core features include input validation, multi-arch manifest creation, and OCI-compliant output, with optional advanced steps for cache hints and vulnerability-report hooks. Use cases span microservice packaging, environment parity between dev/stage/prod, and rapid rollback via tagged references. Unique differentiators are explicit multi-arch support, deterministic image naming, and an end-to-end plan that remains agnostic to specific CI platforms while remaining Kubernetes-ready. Typical workflow: select base image and target_arch, specify image_name and tag, choose registry, run build, then push and register a multi-arch manifest. Outputs include a concrete image reference, digest, and manifest documentation for each architecture. The tool emphasizes domain fidelity—OCI specs, Kubernetes conventions, and registry interoperability—while abstracting away runtime configuration specifics to keep builds portable across environments.
