step-1

Step 1. Create the directory structure

1a. Gemfile

1. We will use Serverspec for this, which is a Ruby gem.
2. We create a Gemfile in the directory as per instructions in serverspec.org.

Take a look at the Gemfile.

1b. Stub files

Take a look at the stub files we created:

1. A spec directory which will eventually contain the specification for our Dockerfile.
2. A single spec, Dockerfile_spec.rb which for now just has two require statements.
3. A Dockerfile, which again, is empty.

1c. bundle install, bundle exec rspec

• Now we bundle install to get the dependencies specified in our Gemfile.
• To execute the specs, we would do bundle exec rspec.
• Since there are no specs, you won't see much useful output though.

On to Step 2!

Proceed to the step-2 directory where we will write some failing tests.
