Attach to a docker container with less typing

dock

#!/usr/bin/env ruby

class DockerAttacher
  attr_reader :docker_container

  def initialize(docker_container)
    if docker_container.nil?
      puts "Usage: dock [container_id]\nGet container id with `docker ps`"
    else
      @docker_container = docker_container
    end
  end

  def attach!
    return unless docker_container
    attach_to_docker_container
  end

  private

  def attach_to_docker_container
    exec("docker exec -it #{docker_container} /bin/bash")
  end
end

DockerAttacher.new(ARGV[0]).attach!

dock() {
  docker exec -it $1 /bin/bash
}

:)

Yeah using ruby and creating a class is overkill. ¯\_(ツ)_/¯
