One thing to consider for optimizing the Docker build here is the buildkit feature: https://docs.docker.com/engine/reference/commandline/buildx/ and https://docs.docker.com/engine/reference/commandline/builder/
There is also buildpacks.io which is related, though I'm not sure if it's a feature built into Docker or with other tools only.
