构建Jekyll服务错误演示

这个Dockerfile是无法执行成功的，遇到的一些错误，列举出来

[root@docker ~]# mkdir jekyll

[root@docker ~]# cd jekyll/

[root@docker jekyll]# vim Dockerfile

 

FROM ubuntu:14.04

MAINTAINER wyf

ENV REFRSHED_AT 2017-07-07

 

RUN apt-get -yqq update

RUN apt-get -yqq install ruby2.0ruby2.0-dev make nodejs

RUN rm -rf /usr/bin/ruby2&& ln -s /usr/bin/ruby2.0 /usr/bin/ruby && ruby -v

RUN gem install --no-rdoc --no-ri jekyll

 

VOLUME /date

VOLUME /var/www/html

WORKDIR /date

 

ENTRYPOINT ["jekyll","build","--destination=/var/www/html" ]

安装中的一些报错：

安装一个Ruby支持的Jekyll程序，这里会出现ruby版本过低，所以我加上一条修改ruby指向的链接,红色字体。这样虽然指定了ruby的版本，ruby-dev的版本又无法指定。

修改Dockerfile的内容，改用RVM管理工具来安装，又出现无法使用bash的source命令，那是因为使用Ubuntu的系统，默认使用sh指向的是dash，dash比bash解析脚本快，但缺失一些命令，所以改用centos来进行操作。安装RVM后，需要执行RVM的脚本，执行后无法加入到全局环境变量，使用source /etc/profile也不行，在Dockerfile中必须使用ENV来添加变量

 

构建Jekyll正确方式

[root@docker jekyll]# ls

Dockerfile Gemfile

 

Gemfile的内容

[root@docker jekyll]# vim Gemfile

 

source "https://rubygems.org"

 

# Hello! This is where you manage whichJekyll version is used to run.

# # When you want to use a differentversion, change it below, save the

# # file and run `bundle install`. RunJekyll with `bundle exec`, like so:

# #

# #    bundle exec jekyll serve

# #

# # This will help ensure the proper Jekyllversion is running.

# # Happy Jekylling!

gem "jekyll", "3.5.0"

#

# # This is the default theme for newJekyll sites. You may change this to anything you like.

gem "minima", "~>2.0"

#

# # If you want to use GitHub Pages, removethe "gem "jekyll"" above and

# # uncomment the line below. To upgrade,run `bundle update github-pages`.

# # gem "github-pages", group::jekyll_plugins

#

# # If you have any plugins, put them here!

group :jekyll_plugins do

   gem "jekyll-feed", "~> 0.6"

end

#

#   # Windows does not include zoneinfo files, so bundle the tzinfo-data gem

gem 'tzinfo-data', platforms: [:mingw,:mswin, :x64_mingw, :jruby]

讲解

为什么在dockerfile无法安装成功，下面的操作是在容器中进行安装操作，绿色部分在dockerfile无法跳过，反正我是无法跳过，也请大神们指出方法，所以为了避免，只有使用bundle来安装jekyll

如果不使用bundle来安装jekyll，就会是这个错误，外国网站也有这个错误。
