如何在GitlabCI中使用Dockerfile

将gitlab-ci用于我的节点/反应应用程序，我试图phusion/passenger-nodejs用作基础docker映像

我可以在.gitlab-ci.yml中轻松指定它：

image: phusion/passenger-nodejs:latest

variables:
  HOME: /root

cache:
  paths:
  - node_modules/

stages:
  - build
  - test
  - deploy

set_environment:
  stage: build
  script:
    - npm install
  tags:
  - docker

test_node:
  stage: test
  script:
    - npm install
    - npm test
  tags:
    - docker

但是，Phusion Passenger希望您在Dockerfile中进行配置更改，例如python支持，使用其特殊的init进程等。

#FROM phusion/passenger-ruby24:
#FROM phusion/passenger-jruby91:
FROM phusion/passenger-nodejs:
#FROM phusion/passenger-customizable:

# Set correct environment variables.
ENV HOME /root

# Use baseimage-docker's init process.
CMD ["/sbin/my_init"]

# If you're using the 'customizable' variant, you need to explicitly opt-in
# for features. 
#
# N.B. these images are based on https://github.com/phusion/baseimage-docker, 
# so anything it provides is also automatically on board in the images below 
# (e.g. older versions of Ruby, Node, Python).  
# 
# Uncomment the features you want:
#
#   Ruby support
#RUN /pd_build/ruby-2.0.*.sh
#RUN /pd_build/ruby-2.1.*.sh
#RUN /pd_build/ruby-2.2.*.sh
#RUN /pd_build/ruby-2.3.*.sh
#RUN /pd_build/ruby-2.4.*.sh
#RUN /pd_build/jruby-9.1.*.sh
#   Python support.
RUN /pd_build/python.sh
#   Node.js and Meteor standalone support.
#   (not needed if you already have the above Ruby support)
RUN /pd_build/nodejs.sh

# ...put your own build instructions here...

# Clean up APT when done.
RUN apt-get clean && rm -rf /var/lib/apt/lists/* /tmp/* /var/tmp/*

有没有办法在gitlab-ci中使用Dockerfile？除了apt-get install添加shell脚本以外，还有其他好的方法吗？

是的，在您放置Dockerfile的地方创建另一个Gitlab存储库。在其中添加一个gitlab-ci.yml文件，该脚本文件带有一个脚本命令，用于构建修改后的映像并将其推送到您的私有注册表或Gitlab嵌入式Docker注册表，例如：

script: docker build . -t http://myregistry:5000/mymodified image docker push http://myregistry:5000/mymodified

在其他Gitlab存储库中，相应地更改image:行：

image: http://myregistry:5000/mymodified
