Easyfier for Docker image projects

This gem can be used with rake, in order to provide recurrent tasks related to Docker image development. The following tasks are provided (as default):

rake build[cached]         # Build image
rake exec[command]         # Run a command in a running container
rake push                  # Push image
rake restart               # Restart container
rake run[command]          # Run a command in a new container
rake start                 # Start container as awseome_image
rake stop                  # Stop container

Sample of use

In your Rakefile:

require 'kamaze/docker_image'

Kamaze::DockerImage.new do |config|
  config.name    = 'awseome_image'
  config.version = '4.2.2'

  config.path    = 'image'
  config.verbose = false
end

task default: [:build]

Secure Shell (SSH)

Optionally, ssh task can be enabled:

Kamaze::DockerImage.new do |config|
  config.ssh = {
    enabled: true
  }
end

Now, you can do:

rake build restart ssh[pstree]
rake ssh

SSH will wait (using a timeout) until your container is up and running.
