About:
Kbld is a tool from the Carvel suite that automates building container images from source code and pushing them to registries. It resolves image references in configuration files to immutable digests, ensuring reproducible deployments. This simplifies workflow management by integrating build and publish steps seamlessly.

Key Features:

Builds container images from source with Docker or other backends
Pushes images to registries and resolves to immutable digests
Integrates with Kubernetes configuration for declarative workflows
Supports reproducible builds and multi-arch images

Use Cases:

Automating container image builds in CI/CD pipelines
Updating Kubernetes manifests with newly built image digests
Standardizing image resolution for development and production environments

Alternatives:

Docker Buildx – Docker's native builder offers similar multi-arch support but lacks kbld's declarative config resolution for K8s.
Kustomize – Focuses on config templating without built-in image building and pushing capabilities.
