Is it possible to satisfy all of these requirements at once?
- Use the multi-stage builder pattern
- Use a dynamic image name in the final FROM image
- Don’t bust cache for all the builders with every change to the final FROM image name
It seems to bust cache for any change to the BASE_IMAGE argument, which is unnecessary and inefficient.
