+Running Airflow with a self-signed certificate
+##############################################
+
+Airflow can be configured to run with a self-signed certificate but this
+requires a couple of extra steps to enable Workers to trust the API Server.
+This guide is based on the :doc:`docker-compose/index` setup.
+
+.. caution::
+
+ This procedure is intended for learning, exploration and development. It is
+ not suitable for production use.
+
+Generating the certificate
+==========================
+
+The first step is the generation of the certificate. This requires the addition
+of ``localhost`` and ``airflow-apiserver`` as Subject Alternative Names so that
+the health check and Worker to API Server communications function.
+
+.. code-block:: sh
+
+ export AIRFLOW_CN=example-common-name
+ openssl req -x509 -newkey rsa:4096 -keyout key.pem -out cert.pem \
+ -sha256 -days 3650 -nodes \
+ -subj "/CN=$AIRFLOW_CN" \
+ -addext "subjectAltName=DNS:localhost,DNS:airflow-apiserver"
+
+Where ``example-common-name`` is the common name of your server. Place
+``cert.pem`` and ``key.pem`` in the ``config`` folder.
+
+Altering ``docker-compose.yaml``
+================================
+
+Add the following two environment variables below and alter the API Server URL
+to HTTPS:
+
+.. code-block:: sh
+
+ AIRFLOW__CORE__EXECUTION_API_SERVER_URL:
'https://airflow-apiserver:8080/execution/'
+ # Added to enable SSL
+ AIRFLOW__API__SSL_CERT: '/opt/airflow/config/cert.pem'
+ AIRFLOW__API__SSL_KEY: '/opt/airflow/config/key.pem'
+
+Alter the API Server health check to trust the certificate:
+
+.. code-block:: sh
+
+ airflow-apiserver:
+ <<: *airflow-common
+ command: api-server
+ ports:
+ - "8080:8080"
+ healthcheck:
+ # Add --cacert to trust certificate
+ test: ["CMD", "curl", "--fail", "--cacert",
"${AIRFLOW_PROJ_DIR:-.}/config/cert.pem",
"https://localhost:8080/api/v2/version";]
+
+Running Airflow
+===============
+
+Now you can start all services:
+
+.. code-block:: sh
+
+ docker compose up
+
+The webserver is available at: ``https://localhost:8080``
