+Running Airflow in Docker
+#########################
+
+This quick-start guide will allow you to quickly start Airflow with :doc:`CeleryExecutor </executor/celery>` in Docker. This is the fastest way to start Airflow.
+
+Before you begin
+================
+
+Follow these steps to install the necessary tools.
+
+1. Install `Docker Community Edition (CE) <https://docs.docker.com/engine/installation/>`__ on your workstation.
+2. Install `Docker Compose <https://docs.docker.com/compose/install/>`__ on your workstation.
+
+``docker-compose.yaml``
+=======================
+
+To deploy Airflow on Docker Compose, you should download `docker-compose.yaml <../docker-compose.yaml>`__. This file contains several service definitions:
+
+- ``airflow-scheduler`` - The :doc:`scheduler </scheduler>` monitors all tasks and DAGs, then triggers the
+  task instances once their dependencies are complete.
+- ``airflow-webserver`` - The webserver available at ``http://localhost:8080``.
+- ``airflow-worker`` - The worker that executes the tasks given by the scheduler.
+- ``flower`` - `The flower app <https://flower.readthedocs.io/en/latest/>`__ for monitoring the environment. It is available at ``http://localhost:8080``.
+- ``postgres`` - The database.
+- ``redis`` - `The redis <https://redis.io/>`__ - broker that forwards messages from scheduler to worker.
+
+All these services allow you to run Airflow with :doc:`CeleryExecutor </executor/celery>`. For more information, see :ref:`architecture`.
+
+Running Airflow
+===============
+
+Before starting Airflow for the first time, you need to initialize the database. To do it, run.
+
+.. code-block:: bash
+
+    docker-compose run --rm airflow-webserver \
+        airflow db init
+
+Access to the web server requires a user account, to create it, run:
+
+.. code-block:: bash
+
+    docker-compose run --rm airflow-webserver \
+        airflow users create \
+            --role Admin \
+            --username airflow \
+            --password airflow \
+            --email airflow@airflow.com \
+            --firstname airflow \
+            --lastname airflow
