Pure Rack middleware that reads forward-auth headers (Remote-User, Remote-Email, Remote-Groups, Remote-Name) and exposes parsed user attributes in the Rack env. Includes a test stub for development environments. No Rails dependency.
# holepunch [](http://badge.fury.io/rb/holepunch) [](https://travis-ci.org/undeadlabs/holepunch) Holepunch manages AWS EC2 security groups in a declarative way through a DSL. ## Requirements - Ruby 1.9.3 or newer. ## Installation ```bash gem install holepunch ``` or in your Gemfile ```ruby gem 'holepunch' ``` ## Basic Configuration You need to provide your AWS security credentials and a region. These can be provided via the command-line options, or you can use the standard AWS environment variables: ```bash export AWS_ACCESS_KEY_ID='...' export AWS_SECRET_ACCESS_KEY='...' export AWS_REGION='us-west-2' ``` ## The SecurityGroups file Specify your security groups in a `SecurityGroups` file in your project's root. Declare security groups that you need and the ingresses you want to expose. You can add ingresses using `tcp`, `udp`, and `ping`. For each ingress you can list allowed hosts using group names or CIDR notation. ```ruby group 'web' do desc 'Web servers' tcp 80 end group 'db' do desc 'database servers' tcp 5432, 'web' end group 'log' do desc 'log server' tcp 9999, 'web', 'db', '10.1.0.0/16' end ``` An environment can be specified which is available through the `env` variable. This allows you to have custom security groups per server environment. ```ruby group "#{env}-web" group "#{env}-db" do tcp 5432, "#{env}-web" end ``` Your application may depend on security groups defined by other services. Ensure they exist using the `depends` method. ```ruby depends 'my-other-service' group 'my-service' do udp 9999, 'my-other-service' end ``` You may specify port ranges for `tcp` and `udp` using the range operator. ```ruby group 'my-service' do udp 5000..9999, '0.0.0.0/0' end ``` You can specify ping/icmp rules with `icmp` (alias: `ping`). ```ruby group 'my-service' do ping '10.0.0.0/16' end ``` It can be useful to describe groups of security groups you plan to launch instances with by using the `service` declaration. ```ruby service "#{env}-web" do groups %W( admin #{env}-log-producer #{env}-web ) end ``` ## Usage Simply navigate to the directory containing your `SecurityGroups` file and run `holepunch`. ``` $ holepunch ``` If you need to specify an environment: ``` $ holepunch -e live ``` You can get a list of security groups for a service using the `service` subcommand. ``` $ holepunch service -e prod prod-web admin,prod-log-producer,prod-web ``` You can also get a list of all defined services. ``` $ holepunch service --list ``` ## Testing You can run the unit tests by simply running rspec. ``` $ rspec ``` By default the integration tests with EC2 are not run. You may run them with: ``` $ rspec -t integration ``` ## Authors - Ben Scott (gamepoet@gmail.com) - Pat Wyatt (pat@codeofhonor.com) ## License Copyright 2014 Undead Labs, LLC.

Inventory Inventory keeps track of the contents of your Ruby¹ projects. Such an inventory can be used to load the project, create gem specifications and gems, run unit tests, compile extensions, and verify that the project’s content is what you think it is. ¹ See http://ruby-lang.org/ § Usage Let’s begin by discussing the project structure that Inventory expects you to use. It’s pretty much exactly the same as the standard Ruby project structure¹: ├── README ├── Rakefile ├── lib │ ├── foo-1.0 │ │ ├── bar.rb │ │ └── version.rb │ └── foo-1.0.rb └── test └── unit ├── foo-1.0 │ ├── bar.rb │ └── version.rb └── foo-1.0.rb Here you see a simplified version of a project called “Foo”’s project structure. The only real difference from the standard is that the main entry point into the library is named “foo-1.0.rb” instead of “foo.rb” and that the root sub-directory of “lib” is similarly named “foo-1.0” instead of “foo”. The difference is the inclusion of the API version. This must be the major version of the project followed by a constant “.0”. The reason for this is that it allows concurrent installations of different major versions of the project and means that the wrong version will never accidentally be loaded with require. There’s a bigger difference in the content of the files. ‹Lib/foo-1.0/version.rb› will contain our inventory instead of a String: require 'inventory-1.0' class Foo Version = Foo.new(1, 4, 0){ authors{ author 'A. U. Thor', 'a.u.thor@example.org' } homepage 'http://example.org/' licenses{ license 'LGPLv3+', 'GNU Lesser General Public License, version 3 or later', 'http://www.gnu.org/licenses/' } def dependencies super + Dependencies.new{ development 'baz', 1, 3, 0 runtime 'goo', 2, 0, 0 optional 'roo-loo', 3, 0, 0, :feature => 'roo-loo' } end def package_libs %w[bar.rb] end } end We’re introducing quite a few concepts at once, and we’ll look into each in greater detail, but we begin by setting the ‹Version› constant to a new instance of an Inventory with major, minor, and patch version atoms 1, 4, and 0. Then we add a couple of dependencies and list the library files that are included in this project. The version numbers shouldn’t come as a surprise. These track the version of the API that we’re shipping using {semantic versioning}². They also allow the Inventory#to_s method to act as if you’d defined Version as ‹'1.4.0'›. Next follows information about the authors of the project, the project’s homepage, and the project’s licenses. Each author has a name and an email address. The homepage is simply a string URL. Licenses have an abbreviation, a name, and a URL where the license text can be found. We then extend the definition of ‹dependencies› by adding another set of dependencies to ‹super›. ‹Super› includes a dependency on the version of the inventory project that’s being used with this project, so you’ll never have to list that yourself. The other three dependencies are all of different kinds: development, runtime, and optional. A development dependency is one that’s required while developing the project, for example, a unit-testing framework, a documentation generator, and so on. Runtime dependencies are requirements of the project to be able to run, both during development and when installed. Finally, optional dependencies are runtime dependencies that may or may not be required during execution. The difference between runtime and optional is that the inventory won’t try to automatically load an optional dependency, instead leaving that up to you to do when and if it becomes necessary. By that logic, runtime dependencies will be automatically loaded, which is a good reason for having dependency information available at runtime. The version numbers of dependencies also use semantic versioning, but note that the patch atom is ignored unless the major atom is 0. You should always only depend on the major and minor atoms. As mentioned, runtime dependencies will be automatically loaded and the feature they try to load is based on the name of the dependency with a “-X.0” tacked on the end, where ‘X’ is the major version of the dependency. Sometimes, this isn’t correct, in which case the :feature option may be given to specify the name of the feature. You may also override other parts of a dependency by passing in a block to the dependency, much like we’re doing for inventories. The rest of an inventory will list the various files included in the project. This project only consists of one additional file to those that an inventory automatically include (Rakefile, README, the main entry point, and the version.rb file that defines the inventory itself), namely the library file ‹bar.rb›. Library files will be loaded automatically when the main entry point file loads the inventory. Library files that shouldn’t be loaded may be listed under a different heading, namely “additional_libs”. Both these sets of files will be used to generate a list of unit test files automatically, so each library file will have a corresponding unit test file in the inventory. We’ll discuss the different headings of an inventory in more detail later on. Now that we’ve written our inventory, let’s set it up so that it’s content gets loaded when our main entry point gets loaded. We add the following piece of code to ‹lib/foo-1.0.rb›: module Foo load File.expand_path('../foo-1.0/version.rb', __FILE__) Version.load end That’s all there’s to it. The inventory can also be used to great effect from a Rakefile using a separate project called Inventory-Rake³. Using it’ll give us tasks for cleaning up our project, compiling extensions, installing dependencies, installing and uninstalling the project itself, and creating and pushing distribution files to distribution points. require 'inventory-rake-1.0' load File.expand_path('../lib/foo-1.0/version.rb', __FILE__) Inventory::Rake::Tasks.define Foo::Version Inventory::Rake::Tasks.unless_installing_dependencies do require 'lookout-rake-3.0' Lookout::Rake::Tasks::Test.new end It’s ‹Inventory::Rake::Tasks.define› that does the heavy lifting. It takes our inventory and sets up the tasks mentioned above. As we want to be able to use our Rakefile to install our dependencies for us, the rest of the Rakefile is inside the conditional #unless_installing_dependencies, which, as the name certainly implies, executes its block unless the task being run is the one that installs our dependencies. This becomes relevant when we set up Travis⁴ integration next. The only conditional set-up we do in our Rakefile is creating our test task via Lookout-Rake⁵, which also uses our inventory to find the unit tests to run when executed. Travis integration is straightforward. Simply put before_script: - gem install inventory-rake -v '~> VERSION' --no-rdoc --no-ri - rake gem:deps:install in the project’s ‹.travis.yml› file, replacing ‹VERSION› with the version of Inventory-Rake that you require. This’ll make sure that Travis installs all development, runtime, and optional dependencies that you’ve listed in your inventory before running any tests. You might also need to put env: - RUBYOPT=rubygems in your ‹.travis.yml› file, depending on how things are set up. ¹ Ruby project structure: http://guides.rubygems.org/make-your-own-gem/ ² Semantic versioning: http://semver.org/ ³ Inventory-Rake: http://disu.se/software/inventory-rake-1.0/ ⁴ Travis: http://travis-ci.org/ ⁵ Lookout-Rake: http://disu.se/software/lookout-rake-3.0/ § API If the guide above doesn’t provide you with all the answers you seek, you may refer to the API¹ for more answers. ¹ See http://disu.se/software/inventory-1.0/api/Inventory/ § Financing Currently, most of my time is spent at my day job and in my rather busy private life.
