从Dockerfile中的Github捆绑

我试图将我们的Rails应用程序转移到Docker部署,但是我无法通过Github引用来安装捆绑包。

使用下面的Dockerfile:

FROM ruby:2.3.0-slim

MAINTAINER Chris Jewell <chrisjohnjewell@gmail.com>

# Install dependencies:
# - build-essential: To ensure certain gems can be compiled
# - nodejs: Compile assets
# - libpq-dev: Communicate with postgres through the postgres gem
# - postgresql-client-9.4: In case you want to talk directly to postgres
RUN apt-get update && apt-get install -qq -y build-essential nodejs libpq-dev postgresql-client-9.4 --fix-missing --no-install-recommends

# Set an environment variable to store where the app is installed to inside
# of the Docker image.
ENV INSTALL_PATH /ventbackend
RUN mkdir -p $INSTALL_PATH

# This sets the context of where commands will be ran in and is documented
# on Docker's website extensively.
WORKDIR $INSTALL_PATH

# Ensure gems are cached and only get updated when they change. This will
# drastically increase build times when your gems do not change.
COPY Gemfile Gemfile
RUN bundle install

# Copy in the application code from your work station at the current directory
# over to the working directory.
COPY . .

# Provide dummy data to Rails so it can pre-compile assets.
RUN bundle exec rake RAILS_ENV=production DATABASE_URL=postgresql://user:pass@127.0.0.1/dbname SECRET_TOKEN=pickasecuretoken assets:precompile

# Expose a volume so that nginx will be able to read in assets in production.
VOLUME ["$INSTALL_PATH/public"]

# The default command that gets ran will be to start the Unicorn server.
CMD bundle exec unicorn -c config/unicorn.rb

尝试运行docker-compose up时出现以下错误:

You need to install git to be able to use gems from git repositories. For help installing git, please refer to GitHub's tutorial at https://help.github.com/articles/set-up-git

我假设这是因为Gemfile中的行如:

gem 'logstasher', github: 'MarkMurphy/logstasher', ref: 'be3e871385bde7b1897ec2a1831f868a843d8000'

但是,我们也使用一些私人宝石。

是否可以在容器上安装Git?这将如何与Github进行身份验证?

1 个答案:

答案 0 :(得分:2)

  

是否可以在容器上安装Git?

在这种情况下,是的:你可以在&#34; Using Docker to maintain a Ruby gem&#34;上看到一个例子。它Dockerfile包含一个:

# ~~~~ OS Maintenance ~~~~
RUN apt-get update && apt-get install -y git
  

这将如何通过Github进行身份验证?

无需向GitHub进行身份验证即可读取,即克隆。
你需要推回一个gem(发布它),然后你需要你的ssh键(通过卷安装)。
但这不需要。
