*Proposal / *Work-in-progress
An API to build images on Kubernetes using popular strategies and tools like source-to-image, buildpack-v3, kaniko and buildah, in an extensible way.
The following are the BuildStrategies supported by this operator, out-of-the-box:
Users have the option to define their own BuildStrategies and make them available for consumption
by Builds.
Create resources and configuration in order to implement the following strategies.
Create the below CR for starting a buildpacks-v3 Build

status: Running- Install Tekton ( You could use the OpenShift Pipelines Community Operator ).
- Execute
./hack/crd.sh install - Start a sample Kaniko build
- Build, test & run using HACK.md.
