Golang + Linux + Docker error : standard_init_linux.go:211 : no such file or directory

Question

This is not a duplicate because although the error is same, my use case is different from others.

I am compiling a go application to deploy with docker on:

• latest arch linux
• latest docker version, golang:alpine image
• tried with go version 1.13.3 and 1.14.4 linux amd64
• i have no bash scripts or wrong file endings. Whole project is written on this Linux machine
• i can deploy an empty go app that has only a fmt print without any error

however,

when i build it on my OSX machine, and send it to linux, I can deploy that executable to docker without any error

• OSX mojave
• latest docker
• go 1.13.3
• GOOS=linux

Error :

standard_init_linux.go:211: exec user process caused "no such file or directory"

Answer 1

When you compile your go app with cgo enabled the compiler links dynamically to libstdc .

However, golang:alpine image is so small, because it is not using libstdc but a simplified version of it called musl libc.

The error message says

standard_init_linux.go:211: exec user process caused "no such file or directory"

If you connect to your image with

$ docker run -it [image] /bin/sh

you can find your executable in let's say /dist/myexec, but when you try to run that executable, it says err not found, because of not that it can't find your executable, obviously, but it can't find file libc .

The solution is to either

• disable CGO : use CGO_ENABLED=0 while building

• or add

  RUN apk add --no-cache libc6-compat
  

  to your Dockerfile

• or do not use golang:alpine

To have a all static binary executable, build it with:

$ CGO_ENABLED=0 GOOS=linux go build -a -ldflags '-extldflags "-static"' .
