You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: local_minio_s3.rb
    path of file: ./repos/discourse/script
    
    the code of the file until where you have to start completion: #!/usr/bin/env ruby
# frozen_string_literal: true

require "minio_runner"

class ExecuteLocalMinioS3
  def run
    begin
      start_minio
      save_old_config
      change_to_minio_settings
      puts "Press any key when done..."
      gets
      restore_old
    rescue SystemExit, Interrupt
      restore_old
      raise
    end
  end

  def start_minio
    Min
    
  def start_minio
    MinioRunner.config do |minio_runner_config|
      minio_runner_config.minio_domain = ENV["MINIO_RUNNER_MINIO_DOMAIN"] || "minio.local"
      minio_runner_config.buckets =
        (
          if ENV["MINIO_RUNNER_BUCKETS"]
            ENV["MINIO_RUNNER_BUCKETS"].split(",")
          else
            ["discoursetest"]
          end
        )
      minio_runner_config.public_buckets =
        (
          if ENV["MINIO_RUNNER_PUBLIC_BUCKETS"]
