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: exec_command.rb
    path of file: ./repos/kontena/cli/lib/kontena/cli/containers
    
    the code of the file until where you have to start completion: require_relative '../helpers/exec_helper'

module Kontena::Cli::Containers
  class ExecCommand < Kontena::Command
    include Kontena::Cli::Common
    include Kontena::Cli::GridOption
    
    def execute
      exit_status = container_exec("#{current_grid}/#{self.container_id}", self.cmd_list,
        interactive: interactive?,
        shell: shell?,
        tty: tty?,
      )

      exit exit_status unless exit_status.zero?
    end
