This is an exmaple of using Serverspec to test Dockerfiles
Install Serverspec and the require gems with bundler:
bundle install
This exmaple assumes you have Docker installed, running and configured.
bundle exec rake
The above will run Serverspec and using the docker-api gem it will
- Build a Docker image from the Docker file found in the top level dictrories (4.4 and 6.3)
- Create a container of that image,
- Run the tests found in
spec/
on the container - Delete the images and containers if the test was successful
The Dockerfiles are based on the offiial docker-node image.
You could also use the docker-api gem to pull exisiting images from the Docker hub and run tests against that image.
So for instance, a pull_image helper could look something like this:
def pull_image(image)
puts "Pulling image #{image}..."
@image = Docker::Image.create('fromImage' => imge)
set :os, :family => 'debian'
set :backend, :docker
set :docker_image, @image.id
puts "Running tests..."
end
