Need technical information to make OracleDatabase 19.3 slim docker container

I've built oracle/database:19.3.0-ee image using the Dockerfile in this repo, and noticed it's not quite usable in integration tests; it takes 882 seconds to start up on my machine.

Previously, I've used the slim image of store/oracle/database-enterprise:12.2.0.1-slim. On my machine, the regular 12.2c container took 328 seconds, but the slim version took 84 seconds. According to https://container-registry.oracle.com or https://hub.docker.com, details for the slim image are:

Oracle Database Server 12.2.0.1 Enterprise Edition Slim Variant The Slim Variant (12.2.0.1-slim tag) of EE has reduced disk space (4GB) requirements and a quicker container startup. This image does not support the following features - Analytics, Oracle R, Oracle Label Security, Oracle Text, Oracle Application Express and Oracle DataVault.

May I get the Dockerfile used to produce store/oracle/database-enterprise:12.2.0.1-slim, or technical details to produce 19.3 slim version?

Please advise. Thanks,

The open #1666 pull request adds -slim variants to all the Database images. You should be able to use the proposed changes to create one yourself.
