The record

Purpose: kpack is a Kubernetes native container build service that builds OCI images using Cloud Native Buildpacks.
Builder configuration: A declarative builder resource configures the buildpack order and operating system stack used for builds.
Automatic rebuilds: Image resources schedule rebuilds when source code or builder buildpacks or stacks change.
One-off builds: A build resource can execute a single Cloud Native Buildpacks OCI image build.
Image registry: Built OCI images are published to a configured image tag, and additional tags must use the same registry because cross-registry exporting is unsupported.
Caching: Image resources support volume-based or registry-based build caching.
Credentials: Kubernetes secrets can provide credentials for publishing images to Docker registries and accessing private Git repositories.
Integrations: The documentation includes examples for Docker Hub, Google Container Registry, and GitHub credentials.
Service bindings: Legacy Cloud Native Buildpacks service bindings are deprecated in kpack.io/v1alpha2 and are expected to be removed; the docs direct users to Kubernetes Service Binding configuration.
Security behavior: SSH host key checking for Git credentials is disabled by default and can be enabled through a controller environment variable.
Installation requirements: Installation requires Kubernetes 1.22 or later, kubectl, cluster-admin permissions, and an accessible Docker V2 registry.
Support: The project README points users to a weekly working group and the CNCF Slack community.
License: The repository identifies its license as Apache-2.0.
Price from: Free
