Grab and eval Ruby code via HTTP. You don't care about security, right? This gem is Dr. Nic's fault. We were looking for an easy way to run Ruby code that was publicly available on a web server, and though we've all written something to do this a time or two, we couldn't find a convenient gem. I hacked up a quick example: ruby -rubygems -ropen-uri -e \ 'eval open("http://gist.github.com/raw/473222/snippet.rb").read' \ jbarnette dr-nic-magic-awesome ...but why use a simple Ruby one-liner when we can go overboard and package it as a gem? While we're at it, why not add a tiny bit of extra sugar for Gists? This is not an original idea. It's been done a ton of times before, but this one is ours. Don't use it for anything real or it'll melt your face.
# ruby unshare (runshare) This tool allows to unshare Linux namespaces. The implementation is similar to the unshare(1) tool. ## Installation Add this line to your application's Gemfile: ```ruby gem 'runshare' ``` And then execute: $ bundle Or install it yourself as: $ gem install runshare ## Usage > require "runshare" > RUnshare::unshare For example: cat > test.rb require "runshare" pid = RUnshare::unshare( :clone_newpid => true, :clone_newns => true, :clone_newcgroup => true, :clone_newipc => true, :clone_newuts => true, :clone_newnet => true, :clone_newtime => true, :fork => true, :mount_proc => "/proc", # docker export $(docker create hello-world) | tar -xf - -C rootfs :root => "/tmp/rootfs" ) if pid == 0 # child puts "--- #{Process.pid}" if system("/hello") != true raise "bad" end puts "--- done" else # parent puts "-- unshare=#{pid}, pid=#{Process.pid}" puts "-- exit=#{Process.waitpid(pid)}" end ^D sudo ruby -I ./lib ./test.rb ## Quick start $ rake compile && echo 'require "runshare"; RUnshare::unshare(:clone_newuts => true)' | irb install -c tmp/x86_64-linux/runshare/2.4.10/runshare.so lib/runshare/runshare.so cp tmp/x86_64-linux/runshare/2.4.10/runshare.so tmp/x86_64-linux/stage/lib/runshare/runshare.so Switch to inspect mode. require "runshare"; RUnshare::unshare ## Ruby <2.5 If your app is single threaded and you are observing: eval:1: warning: pthread_create failed for timer: Invalid argument, scheduling broken Just ignore it with some degree of bravity. You also can silence it by setting: $VERBOSE = nil ## Development After checking out the repo, run `bin/setup` to install dependencies. Then, run `rake spec` to run the tests. You can also run `bin/console` for an interactive prompt that will allow you to experiment. To install this gem onto your local machine, run `bundle exec rake install`. To release a new version, update the version number in `version.rb`, and then run `bundle exec rake release`, which will create a git tag for the version, push git commits and tags, and push the `.gem` file to [rubygems.org](https://rubygems.org). ## Contributing Bug reports and pull requests are welcome on GitHub at https://github.com/sitano/runshare. This project is intended to be a safe, welcoming space for collaboration, and contributors are expected to adhere to the [Contributor Covenant](http://contributor-covenant.org) code of conduct. ## License The gem is available as open source under the terms of the [MIT License](https://opensource.org/licenses/MIT).
