Facing issue while running prebuild binaries in alpine docker container

[deekshith-elear]

Hi,
I'm trying to run simple hello.c binary which is built in my machine and created docker image for it using alpine as base image

Code compilation

gcc hello.c -o hello

DOCKER FILE

FROM alpine:3.4
RUN apk add --update gcc libc-dev
COPY hello /usr/bin/

DOCKER CONTAINER

1. docker build . -t helloworld:1
2. docker run --rm -it helloworld:1
3. /bin/sh: hello: not found

can anyone help me out to resolve this issue

You need to build it against musl libc. You cannot really copy in a binary built on MacOS, Windows or GNU/Linux and expect it to run in Alpine. Well, you can run Windows binary with wine and you may be able to run GNU/Linux binary if you install either libc6-compat or gcompat. It may work, even if there are no guarantee that it does.
