title: What is context: . in docker-compose?
body: <p>I am trying learn docker and created my first docker compose file. Basically I am trying to create a Django web microservice and use docker compose file to manage it. Here is my code for my docker-compose.yml:</p>
  <pre><code>version: &quot;3&quot;
  
  services:
    app:
      build:
        context: .
      ports:
        - &quot;8000:8000&quot;
      volumes:
        - ./app:/app
      command: &gt;
        sh -c &quot;py manage.py runserver 0.0.0.0:8000&quot;
  </code></pre>
  <p>I don't understand the use of <code>context: .</code> Can someone please explain me this</p>
