Description

We are migrating from the Docker store/oracle/database-enterprise:12.2.0.1-slim image to building from this GH repo using the SingleInstance files.

One thing we've noticed immediately is that the size of the resulting images is 3x bigger (2G for the store -slim image, 6G for the GH version).

Aside from using the --squash experimental Docker feature, are there aspects of the Oracle Database image that could safely be removed? We note the products/ space seems to be where the bulk of the file size is, but we're not sure if there are possibly optional components that we could safely remove in our post-setup step.

Research direction
Investigate the Dockerfiles in the SingleInstance directory to identify which Oracle components are installed. The `products/` directory likely contains large binaries; check if any can be removed (e.g., unused language packs, documentation). Consider multi stage builds to copy only essential files. Review the single comment on the issue for any hints.
