There are reasons to choose other images over Alpine, but IMO avoiding musl libc is not one of them. In the case of x86_64 architecture, if you symlink ld-musl-x86_64.so.1 to ld-linux-x86-64.so.2, you can use musl libc in place of glibc, which is functional for most use cases. See this example Dockerfile to use a linux/arm64 Go release with an Alpine base image: FROM alpine:3.12 RUN ln -s lib lib64 && \ ln -s ld-musl-x86_64.so.1 lib/ld-linux-x86-64.so.2 RUN set -o pipefail && \ wget -O- https://golang.org/dl/go1.15.6.linux-amd64.tar.gz | \ tar xzC usr/local && \ rm -r usr/local/go/pkg/linux_amd64_race ENV PATH=${PATH}:/usr/local/go/bin \ GOPATH=/go Binaries built using this approach can run on other linux/amd64 platforms, even though CGO was not disabled. As a side note, the resultant image for the above Dockerfile is 369MB, whereas golang:alpine is only 299MB. The size difference is /usr/local/go/pkg/linux_amd64_race, which golang:alpine does not include (but golang:buster, for example, does). -Zach On Thu, Dec 17, 2020 at 5:44 AM Space A. <reexist...@gmail.com> wrote: > Hi Constantine, > > In our project we'd chosen debian-slim images vs alpine few years ago due > to a number of reasons, if I recall arguments were like: > > 1. presence of libc > 2. bugs and performance issues of alpine > 3. security issues of alpine > 4. debian is more suitable for testing with huge amount of tools available > out of the box, if needed > > > After all, talking about saving few tens of megs of hdd space per image > (it's the main reason for ppl selecting alpine) is ridiculous nowadays IMO. > > > > среда, 16 декабря 2020 г. в 20:10:49 UTC+3, Constantine Vassilev: > >> What about the size of images?
