Linux Question

libgit2 alpine linux docker error

Ok, This is above my understanding. I have really no idea what exactly is wrong here but something is. I am on the verge of breaking by banging my head on the wall and yet nothing came up. Can any kind soul please help me.

This is my Dockerfile -

FROM golang:1.7-alpine
RUN echo http://dl-4.alpinelinux.org/alpine/edge/testing >> /etc/apk/repositories
RUN apk update && apk upgrade && apk add --no-cache bash git openssh alpine-sdk libgit2

RUN pkg-config --print-errors --exists libgit2


I have wrote it with advice from here - How do I install libgit2 on Alipne linux

And this is the end result -

Step 4 : RUN pkg-config --print-errors --exists libgit2
---> Running in f69f97142e81
Package libgit2 was not found in the pkg-config search path.
Perhaps you should add the directory containing `libgit2.pc'
to the PKG_CONFIG_PATH environment variable
Package 'libgit2', required by 'world', not found
The command '/bin/sh -c pkg-config --print-errors --exists libgit2' returned a non-zero code: 1


So what is it that is wrong? Why it can not see the installed libgit2 (0.24.1-r0). I really tried every possible way to get this one package built and installed in my docker container and I can not simply do it. I have no idea what is wrong. Please help me.

-------------- EDIT

The last command in my Dockerfile is actually taken from here http://lists.subsurface-divelog.org/pipermail/subsurface/2014-November/015646.html

And certainly the issue depicted there and the one that I have is not the same

---------------- EDIT 2

Anyone interested in doing the effort all by your self can follow this -

FROM golang:1.7-alpine
ENV TARGET venv
RUN echo http://dl-4.alpinelinux.org/alpine/edge/testing >> /etc/apk/repositories
RUN apk update && apk upgrade && apk add --no-cache bash git openssh alpine-sdk libcurl
RUN apk update && apk add cmake
RUN git clone git://github.com/libgit2/libgit2.git
WORKDIR $GOPATH/libgit2
RUN git checkout v0.24.0 && rm -rf build && mkdir build && cd build \
&& cmake .. -DCMAKE_INSTALL_PREFIX=$TARGET -DBUILD_CLAR=OFF && cmake --build . --target install
ENV PKG_CONFIG_PATH /go/libgit2/build/venv/lib/pkgconfig:$PKG_CONFIG_PATH


For a simpler and cleaner approach follow the accepted answer. This one only has the advantage of having libgit2 version which is not available via apk yet.

Answer

You are trying to compile a package using libgit2, so you need the libgit2-dev development package with the headers, pc file, etc.

This docker file file builds git2go successfully:

FROM golang:1.7-alpine
RUN apk update && apk upgrade && apk add --no-cache bash git openssh alpine-sdk libgit2-dev
RUN go get -v github.com/libgit2/git2go
