During authoring of the UBI builder images, the limitations of Extensions were better understood.
Extensions are unable to write layers, and thus cannot configure the runtime environment via layers.
To perform this kind of configuration, we can create a Buildpack to act as a companion to the Extension.
As discussed on Working Group call. This PR includes the companion Buildpack repo's into the UBI RFC.
Use Cases
UBI-Java-Extension will install the runtime.
UBI-Java-Buildpack will apply the runtime configuration via layers.
Nodejs will be similar.
