How to get doctrine container service in symfony 4?

Question

symfony

Good day to all, tell me how you can access the doctrine container in an empty class?
I have a class:

class MyClass{
  public function work(){
      $doctrine = $this->getContainer()->get('doctrine'); // я хочу сделать что то вроде этого
  }
}

Usually I wrote in the controller $this->getContainer()->get('doctrine'); and everything worked, but how to do it in a simple class?
What should be written in use? Should a class inherit something?
Tell me who knows?

Answer 1

You don't need a doctrine container in an empty class.
What do you want to do in this case? This is done in other ways.

Answer 2

Documentation section explaining how this is done:
https://symfony.com/doc/current/service_container....
