How to install Go in alpine linux

I just copied it over using multi stage builds, seems to be ok so far

FROM XXX
 
COPY --from=golang:1.13-alpine /usr/local/go/ /usr/local/go/
 
ENV PATH="/usr/local/go/bin:${PATH}"

The following Dockerfile worked for me. Simpler and more abstract.

FROM alpine:latest

RUN apk add --no-cache git make musl-dev go

# Configure Go
ENV GOROOT /usr/lib/go
ENV GOPATH /go
ENV PATH /go/bin:$PATH

RUN mkdir -p ${GOPATH}/src ${GOPATH}/bin

# Install Glide
RUN go get -u github.com/Masterminds/glide/...

WORKDIR $GOPATH

CMD ["make"]

Thanks BMitch.

I compiled the go source code and performed the below steps inside alpine image container.

echo "installing go version 1.10.3..." 
apk add --no-cache --virtual .build-deps bash gcc musl-dev openssl go 
wget -O go.tgz https://dl.google.com/go/go1.10.3.src.tar.gz 
tar -C /usr/local -xzf go.tgz 
cd /usr/local/go/src/ 
./make.bash 
export PATH="/usr/local/go/bin:$PATH"
export GOPATH=/opt/go/ 
export PATH=$PATH:$GOPATH/bin 
apk del .build-deps 
go version

With Alpine, you have libmusl instead of glibc. Alpine's libmusl is not a 1 for 1 replacement. Code linked against glibc will show a not found error which is actually from the dynamic linker. You can see what libraries are linked to the binary with ldd:

/ # ldd /usr/local/go/bin/go
        /lib64/ld-linux-x86-64.so.2 (0x7f63ceed1000)
        libpthread.so.0 => /lib64/ld-linux-x86-64.so.2 (0x7f63ceed1000)
        libc.so.6 => /lib64/ld-linux-x86-64.so.2 (0x7f63ceed1000)

There are two options. The preferred option, and one used by docker's go images on Alpine, is to compile the go binaries on Alpine. You can see this in the Dockerfile for the golang image: https://github.com/docker-library/golang/blob/69f2d2a132565bf60afc91813801a3bdcc981526/1.10/alpine3.8/Dockerfile

The other option is to install glibc on Alpine, but once you start doing things like that, I'd question why use Alpine at all, and whether Debian or CentOS would be a more appropriate base image for you. Alpine has a wiki topic on this and there are third parties that have created glibc packages for alpine.

I found the best way to get golang up running in alpine linux is to install it from source. This is also way followed in the official alpine go docker images.

FROM alpine:3.12

ARG GOLANG_VERSION=1.14.3

#we need the go version installed from apk to bootstrap the custom version built from source
RUN apk update && apk add go gcc bash musl-dev openssl-dev ca-certificates && update-ca-certificates

RUN wget https://dl.google.com/go/go$GOLANG_VERSION.src.tar.gz && tar -C /usr/local -xzf go$GOLANG_VERSION.src.tar.gz

RUN cd /usr/local/go/src && ./make.bash

ENV PATH=$PATH:/usr/local/go/bin

RUN rm go$GOLANG_VERSION.src.tar.gz

#we delete the apk installed version to avoid conflict
RUN apk del go

RUN go version

If the basic requirement is to have specific go version installed inside alpine based docker image then refer these images available on official golang dockerhub account.

docker pull golang:1.12-alpine
docker pull golang:1.11-alpine

Just in case someone encounters the same issue with me.

I was able to install the golang1.17.6 ion Alpine3.15 by following @Yogesh Jilhawar 's answer.

When I ran the command apk add --no-cache --virtual .build-deps bash gcc musl-dev openssl go, I got

ERROR: unable to select packages:
  go (no such packages):
    required by: world[go]

Then I tried to install the "gcc-go", it installs. After that, I can build the golang from the source successfully.

There Is the Alpine package, with the latest versione of golang:

pkg --update add go
