reduce image size
tiehuis opened this issue · comments
The image is fairly large and could probably be cleaned up a fair amount. llvm likely takes a large portion however and I'm unsure the savings we could get there.
Look into squashing the image at least.
$ docker history zig

I think we should build llvm from source in release mode, compile zig against it statically, then delete all the filesystem stuff that isn't needed. the final result should be something like 80 MB.
See if that's better. I tried these changes and got an image that is about 200 MB and pushed it to andrewrk/zig.
