Full Description


Drydocker provides a simple wrapper to run tests inside a container every
time you make a change to your code. It listens to filesystem changes on your
host and runs a docker command every time it detects anything. It is a
pre-requisite of use that you have a docker image you can run your tests in.


Drydocker can be installed as a gem - gem install drydocker (or, on OS X,
sudo gem install drydocker)


When installed as a gem, you will have a drydocker executable. Running with
-h will provide up-to-date usage instructions.

Basic usage is to run drydocker in the top level directory of the project
you're working on - by default, it will mount that directory into an image
that has enough for running rspec installed, and will run rspec spec every
time it sees a change in the directory.

You can specify particular images to run in and commands to run at command line
if you need to run your tests in a different way or container. Please refer to
the output of drydocker -h for more information on the flags to use.

Contributing to drydocker

  • Check out the latest master to make sure the feature hasn't been implemented or the bug hasn't been fixed yet.
  • Check out the issue tracker to make sure someone already hasn't requested it and/or contributed it.
  • Fork the project.
  • Start a feature/bugfix branch.
  • Commit and push until you are happy with your contribution.
  • Make sure to add tests for it. This is important so I don't break it in a future version unintentionally.
  • Create a Pull Request.



Checkout the code, make changes, run rake version:bump:minor
(see for options),
git push - wercker will do the rest.
