Running dep ensure -vendor-only inside Docker Hang

问题:

My Dockerfile:

FROM golang:1.11.4
RUN apt-get update && apt-get install git bash curl -yqq
ENV ENV test
ENV GIT_TERMINAL_PROMPT=1
ENV GITHUB_TOKEN XXXXXXXXXXXXXXXXXX 
    RUN curl -Ls https://github.com/Masterminds/glide/releases/download/v0.12.3/glide-v0.12.3-linux-amd64.tar.gz | tar xz -C /tmp \
&& mv /tmp/linux-amd64/glide /usr/bin/
RUN curl https://raw.githubusercontent.com/golang/dep/master/install.sh | sh
RUN mkdir -p $GOPATH/src/github.com/<Myrepo>/
COPY . $GOPATH/src/github.com/<Myrepo>/
WORKDIR $GOPATH/src/github.com/<Myrepo>/
    
RUN dep ensure -vendor-only

When i am building this docker file it hangs at RUN dep ensure -vendor-only

It fails to pull the dependencies which are private repos

Is there any possiblities to store git credentials inside Docker or any way to build Docker with one or more private repos of GOlang

回答1:

Use some thing like this

# ensure that the private Github repo is
# accessed using SSH instead of HTTPS
RUN ssh-keyscan github.com > /root/.ssh/known_hosts
RUN echo "$SSH_KEY" > /root/.ssh/id_rsa && chmod 0600 /root/.ssh/id_rsa
RUN echo '[url "ssh://[e-mail]/*your_repo*/"]' >> /root/.gitconfig && echo 'insteadOf = https://github.com/*your_repo*/' >> /root/.gitconfig

Refer this to add ssh key to your git repo

回答2:

Adding .netrc file will pass credentials inside the docker containers and helps to pull more than one private repositories to build dependencies

#vim .netrc
  machine github.com
      login < your github token >

add those 2 lines and pass your github token

FROM golang:1.11.4
RUN apt-get update && apt-get install git bash curl -yqq
ENV ENV test
ENV GIT_TERMINAL_PROMPT=1
ENV GITHUB_TOKEN XXXXXXXXXXXXXXXXXX 
       
RUN curl -Ls https://github.com/Masterminds/glide/releases/download/v0.12.3/glide-v0.12.3-linux-amd64.tar.gz | tar xz -C /tmp \
&& mv /tmp/linux-amd64/glide /usr/bin/
RUN curl https://raw.githubusercontent.com/golang/dep/master/install.sh | sh
RUN mkdir -p $GOPATH/src/github.com/<Myrepo>/
COPY . $GOPATH/src/github.com/<Myrepo>/
COPY .netrc /root/
WORKDIR $GOPATH/src/github.com/<Myrepo>/
        
RUN dep ensure -vendor-only
