docker - 如何在 Gitlab CI 中使用 Dockerfile

Question

在我的节点/ react 应用程序中使用 gitlab-ci，我正在尝试使用 phusion/passenger-nodejs作为基础 docker 镜像

我可以在 .gitlab-ci.yml 中轻松指定:

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 希望您进行配置更改，例如python支持，在Dockerfile中使用他们特殊的init进程等。

#FROM phusion/passenger-ruby24:<VERSION>
#FROM phusion/passenger-jruby91:<VERSION>
FROM phusion/passenger-nodejs:<VERSION>
#FROM phusion/passenger-customizable:<VERSION>

# 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/*

有没有办法将 Dockerfile 与 gitlab-ci 一起使用？除了 apt-get install 之外，还有其他好的工作吗？并添加 shell 脚本？

Answer 1

是的，创建第二个 Gitlab 存储库，将 Dockerfile 放入其中。在那里，您添加一个带有脚本命令的 gitlab-ci.yml 文件，该脚本命令构建您修改的图像并将其推送到您的私有(private)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
在您的其他 Gitlab 存储库中，更改 image:相应地行:
image: http://myregistry:5000/mymodified
