Support docker-compose push

Please consider supporting docker-compose push.

@jamiejackson Thanks for the suggestion! How would you imagine it working?

I'm new to pushing images, so I'm not sure I'm considering everybody's workflow, but I think this is how I'd expect it to work:

config.vm.provision :docker_compose,
  env: { "PORT" => "#{port}" },
  yml: ["/vagrant/docker-compose-base.yml","/vagrant/docker-compose.yml"],
  command_options: {
    up: "-d --remove-orphans",
    push: "service_a service_d service_f"
  },
  rebuild: true,
  push: true,
  project_name: "myproject",
  run: "always"

provisioner.rb

require_relative "errors/docker_compose_error"
require_relative "installer"
require_relative "docker_compose"

module VagrantPlugins
  module DockerComposeProvisioner
    class Provisioner < Vagrant.plugin("2", :provisioner)
      def initialize(machine, config, installer = nil, docker_compose = nil)
        super(machine, config)

        @installer = installer || Installer.new(@machine, @config)
        @docker_compose = docker_compose || DockerCompose.new(@machine, @config)
      end

      def provision
        @installer.ensure_installed

        return unless @config.yml

        if @config.rebuild
          @docker_compose.rm
          @docker_compose.build
        end

        if @config.push
          @docker_compose.push
        end

        @docker_compose.up
      end
    end
  end
end

Hmm, if it was added in this way it would push images automatically everytime you brought up a vagrant image, which might be out of scope of the main use cases of using this plugin. It might make sense. While we see if anyone else comments on this issue, you should be able to get essentially the same behavior by adding something like the following to your Vagrantfile after the :docker_compose entry.

config.vm.provision :shell, inline: "cd /vagrant && docker-compose push"

My workaround is similar:

  main_stack_ymls_inline = main_stack_ymls.map{ |x| main_stack_ymls_inline += "-f #{x}" }.join(' ')
  compose_env_vars_inline = compose_env_vars.map{ |key, value| "#{key}='#{value}'" }.join(' ')
  services_to_push_inline = services_to_push.join(' ')

  config.vm.provision "docker_compose_build",
    type: "shell",
    inline: "#{compose_env_vars_inline} docker-compose  #{main_stack_ymls_inline} build #{services_to_push_inline}"
  config.vm.provision "docker_compose_push",
    type: "shell",
    inline: "#{compose_env_vars_inline} docker-compose  #{main_stack_ymls_inline} push #{services_to_push_inline}"
    
  config.vm.provision  :docker_compose,
    options: "-p docker",
    yml: main_stack_ymls,
    command_options: { up: "-d --remove-orphans" },
    env: compose_env_vars,
    rebuild: true,
    run: "always",
    compose_version: docker_compose_version
