• Failures to run acceptance tests/publishing when creating a release #46
• Failure: Create Release workflow #13

Summary

On each release we ship one builder image and multiple run images despite we generate from the create.sh script multiple build.oci images one for each engine, majorVersion. Therefor On our integration/acceptance tests, is uneccesary to test all the build.oci images located under each build-<engine>-<majorVersion> as we:

• dont ship them on any container registry or on the release assets
• They dont participate on the build process when we build an app, as the builder uses only the one that is pushed on the container registry/release assets https://github.com/paketo-community/builder-ubi-base/blob/47a0a253e7429b1145cef1e35c9eb5aef87c0dc7/builder.toml#L74

Use Cases

This PR alters the function utils.GenerateBuilder to always point the builder image to build/build.oci
