Optimise the Docker image
CMCDragonkai opened this issue · comments
Specification
The docker image produced contains alot of build/compile time dependencies brought in from Nix. Note that we already stopped bringing in NPM dev dependencies, so this is about Nix.
For example, a docker image from ts-demo-lib contains these things:
[nix-shell:~/Projects/TypeScript-Demo-Lib]$ docker save typescript-demo-lib-1.3.1:scg60dr0kpn71fb745bcpkbmq7nyrhvl | tar x --to-stdout --wildcards '*/layer.tar' | tar t --exclude="*/*/*/*"

Many of those nix store outputs are not necessary. Especially things like gcc and python3.
This is about 300MiB unpacked. Or 100 MiB packed as a .tar.gz image.
