Question

我尝试使用docker安装Rails，出现以下错误

Installing websocket-driver 0.6.5 with native extensions
Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

current directory:
/usr/local/bundle/gems/websocket-driver-0.6.5/ext/websocket-driver
/usr/local/bin/ruby -r ./siteconf20180911-15-1atjs2q.rb extconf.rb
Cannot allocate memory - /usr/local/bin/ruby -r ./siteconf20180911-15-1atjs2q.rb
extconf.rb 2>&1

Gem files will remain installed in /usr/local/bundle/gems/websocket-driver-0.6.5
for inspection.
Results logged to
/usr/local/bundle/extensions/x86_64-linux/2.5.0/websocket-driver-0.6.5/gem_make.out

An error occurred while installing websocket-driver (0.6.5), and Bundler cannot
continue.
Make sure that `gem install websocket-driver -v '0.6.5' --source
'https://rubygems.org/'` succeeds before bundling.

In Gemfile:
  rails was resolved to 5.1.6, which depends on
    actioncable was resolved to 5.1.6, which depends on
      websocket-driver

这是我的docker文件

FROM ruby:latest

RUN apt-get -y update && apt-get install -y curl

RUN curl -sL https://deb.nodesource.com/setup_8.x | bash -

RUN apt-get -y update && apt-get -y install nodejs

RUN mkdir -p /app

WORKDIR /app

COPY . /app

RUN gem install rails

RUN  /app/bin/setup

RUN chmod -R 755 /app

EXPOSE 3000

CMD ["bundle", "exec", "puma", "-C", "config/puma.rb","-e","alpha"]

我尝试在我的Mac机器上安装其工作正常。我从数字海洋购买了新的ubuntu 16.04服务器，然后尝试安装该服务器。我得到这个错误。我正在使用Docker版本18.03.1-ce，内部版本9ee9f40。

在我的app / bin / setup中，我正在以下命令下运行

#!/usr/bin/env ruby
require 'pathname'
require 'fileutils'
include FileUtils

# path to your application root.
APP_ROOT = Pathname.new File.expand_path('../../', __FILE__)

def system!(*args)
  system(*args) || abort("\n== Command #{args} failed ==")
end

chdir APP_ROOT do
  # This script is a starting point to setup your application.
  # Add necessary setup steps to this file.

  puts '== Installing dependencies =='
  system! 'gem install bundler --conservative'
  system('bundle check') || system!('bundle install')

  puts "\n== Removing old tempfiles =="
  system! 'bin/rails tmp:clear'

  puts "\n== Precompiling Assets =="
  system! 'bin/rails assets:precompile'

  puts "\n== Restarting application server =="
  system! 'bin/rails restart'
end

我尝试使用ruby：latest，ruby：2.4.1无法正常工作。

在提出一些建议之后，我在Dockerfile中添加了sudo apt-get install ruby-dev，但这也不起作用

此行表明您的Digital Ocean drop没有足够的RAM来构建依赖关系，因此docker构建失败。

我遇到了同样的问题，不幸的是，您只需要更多的资源即可。

或者，您可以构建映像，标记并推入docker存储库，然后在DO Drop上拉并运行它，以避免构建步骤。

使用高山版本的红宝石。它将占用更少的空间。例如：FROM ruby:2.5.1-alpine
