In this case, I didn't need alpine. I generally aim to get the image as minimal as possible without too much hassle. I end up doing stuff like this alot when I feel like a community image maybe too bloated when something like alpine or distroless can be used. Entry point scripts have all kinds of envars and a shell dependency, I'd rather rebuild the image to cater for my needs and execute the binary directly, and mount in any config via k8s.
