class Vagrant::Action::General::Package
A general packaging (tar) middleware. Given the following options, it will do the right thing:
* package.output - The filename of the outputted package. * package.include - An array of files to include in the package. * package.directory - The directory which contains the contents to compress into the package.
This middleware always produces the final file in the current working directory (FileUtils.pwd)
Attributes
The path to the final output file. @return [String]
Public Class Methods
Calculate the full path of the given path, relative to the current working directory (where the command was run).
@param [String] output the relative path
# File lib/vagrant/action/general/package.rb, line 54 def self.fullpath(output) File.expand_path(output, Dir.pwd) end
# File lib/vagrant/action/general/package.rb, line 62 def initialize(app, env) @app = app env["package.files"] ||= {} env["package.output"] ||= "package.box" @fullpath = self.class.fullpath(env["package.output"]) end
Perform sanity validations that the provided output filepath is sane. In particular, this function validates:
- The output path is a regular file (not a directory or symlink) - No file currently exists at the given path - A directory of package files was actually provided (internal)
@param [String] output path to the output file @param [String] directory path to a directory containing the files
# File lib/vagrant/action/general/package.rb, line 33 def self.validate!(output, directory) filename = File.basename(output.to_s) output = fullpath(output) if File.directory?(output) raise Vagrant::Errors::PackageOutputDirectory end if File.exist?(output) raise Vagrant::Errors::PackageOutputExists, filename: filename end if !Vagrant::Util::Presence.present?(directory) || !File.directory?(directory) raise Vagrant::Errors::PackageRequiresDirectory end end

Compress the exported file into a package
# File lib/vagrant/action/general/package.rb, line 141 def compress # Get the output path. We have to do this up here so that the # pwd returns the proper thing. output_path = fullpath.to_s # Switch into that directory and package everything up Util::SafeChdir.safe_chdir(@env["package.directory"]) do # Find all the files in our current directory and tar it up! files = Dir.glob(File.join(".", "*")) # Package! Util::Subprocess.execute("bsdtar", "-czf", output_path, *files) end end
This method copies the include files (passed in via command line) to the temporary directory so they are included in a sub-folder within the actual box
# File lib/vagrant/action/general/package.rb, line 116 def copy_include_files include_directory = Pathname.new(@env["package.directory"]).join("include") @env["package.files"].each do |from, dest| # We place the file in the include directory to = include_directory.join(dest) @env[:ui].info I18n.t("vagrant.actions.general.package.packaging", file: from) FileUtils.mkdir_p(to.parent) # Copy directory contents recursively. if File.directory?(from) FileUtils.cp_r(Dir.glob(from), to.parent, preserve: true) else FileUtils.cp(from, to, preserve: true) end end rescue Errno::EEXIST => e raise if !e.to_s.include?("symlink") # The directory contains symlinks. Show a nicer error. raise Errors::PackageIncludeSymlink end

File.delete(fullpath) if File.exist?(fullpath) end
This will copy the generated private key into the box and use it for SSH by default. We have to do this because we now generate random keypairs on boot, so packaged boxes would stop working without this.
# File lib/vagrant/action/general/package.rb, line 176 def setup_private_key # If we don't have machine, we do nothing (weird) return if !@env[:machine] # If we don't have a data dir, we also do nothing (base package) return if !@env[:machine].data_dir # If we don't have a generated private key, we do nothing path = @env[:machine].data_dir.join("private_key") if !path.file? # If we have a private key that was copied into this box, # then we copy that. This is a bit of a heuristic and can be a # security risk if the key is named the correct thing, but # we'll take that risk for dev environments. (@env[:machine].config.ssh.private_key_path || []).each do |p| # If we have the correctly named key, copy it if File.basename(p) == "vagrant_private_key" path = Pathname.new(p) break end end end # If we still have no matching key, do nothing return if !path.file? # Copy it into our box directory dir = Pathname.new(@env["package.directory"]) new_path = dir.join("vagrant_private_key") FileUtils.cp(path, new_path) # Append it to the Vagrantfile (or create a Vagrantfile) vf_path = dir.join("Vagrantfile") mode = "w+" mode = "a" if vf_path.file? vf_path.open(mode) do |f| f.binmode f.puts f.puts %Q[Vagrant.configure("2") do |config|] f.puts %Q[ config.ssh.private_key_path = File.expand_path("../vagrant_private_key", __FILE__)] f.puts %Q[end] end end
Write the metadata file into the box so that the provider can be automatically detected when adding the box
# File lib/vagrant/action/general/package.rb, line 158 def write_metadata_json meta_path = File.join(@env["package.directory"], "metadata.json") return if File.exist?(meta_path) if @env[:machine] && @env[:machine].provider_name provider_name = @env[:machine].provider_name elsif @env[:env] && @env[:env].default_provider provider_name = @env[:env].default_provider else return end File.write(meta_path, {provider: provider_name}.to_json) end
