Docker client library to access the Docker remote API.
Add this line to your application's Gemfile:
gem 'docker-client'
And then execute:
$ bundle
Or install it yourself as:
$ gem install docker-client
Ready to be used with Docker version 0.4.0.
So far only the containers resource is supported. The images resource and endpoints in category misc according to the Docker Remote API documentation are not yet implemented (wip: see pull request)
require 'docker'
require 'awesome_print'
docker = Docker::API.new(base_url: 'http://localhost:4243')
containers = docker.containers
# Create a new container
result = containers.create(['/bin/sh', '-c', 'while true; do echo hello world; sleep 1; done'], 'base')
container_id = result["Id"]
ap result
# Start created container
containers.start(container_id)
# Get container details (inspect)
details = containers.show(container_id)
ap details
# Get file system changes of container
changes = containers.changes(container_id)
ap changes
# Attach to container for 3 seconds
options = {stdout: true, stderr: false}
containers.attach(container_id, options, 3) do |data|
puts ">> #{data}"
end
# Get all output since container is started
output = containers.logs(container_id)
ap output
# List all running containers
running_containers = containers.list
ap running_containers
# Stop container
containers.stop(container_id)
# Remove container
containers.remove(container_id)All tests are stubbed with VCR. You can edit the setting config.default_cassette_options in spec_helper.rb to run the tests against the docker API. Set it to {:record => :all}. This will alos re-record all VCR request/response. To run the tests stubbed again uncomment the before mentioned setting.
