I think one of two things could be happening, but I didn't want to rat hole the presentation. 1. We are not using the word base image correctly? 2. We are planning on releasing Middleware base images? 3. More complicated. Relies on RHEL, but squashed (still has a base image of RHEL) If #1, check out this article [1] which I did a ton of homework on and references Docker's documentation, which defines a base image as an image with no parent layer. If #2, I think the RHEL team and the middleware team should talk. I believe we really need to make sure all software in Red Hat products rely on the RHEL "base image" and should probably NOT be creating their own base images. If #3, I think we should discuss what we message to the world (especially customers) about how these are built and we should probably be careful calling them base images. Perhaps, something like an Application Image or Composed Image? Perhaps talking about how they an be used as base images, but are actually rely on a RHEL base image? It might not seem important in this small case, but I foresee massive confusion if we don't perfectly align now before we 1000s of images (currently at just over 100 and growing fast).
