+## Drupal 8 with MySQL
+This example defines one of the basic setups for Drupal. More details on how this works can be found on the official [drupal image page](https://hub.docker.com/_/drupal).
+
+
+Project structure:
+```
+.
+├── docker-compose.yaml
+└── README.md
+```
+
+[_docker-compose.yaml_](docker-compose.yaml)
+```
+services:
+  db:
+    image: mysql:8.0.19
+    ...
+  drupal8-cms:
+    image: drupal:8-apache
+    ports:
+      - 80:80
+    restart: always
+    ...
+```
+
+When deploying this setup, docker-compose maps the Drupal container port 80 to
+port 80 of the host as specified in the compose file.
+
+## Deploy with docker-compose
+
+```
+$ docker-compose up -d
+Creating network "drupal8-mysql_default" with the default driver
+Pulling db (mysql:8.0.19)...

+
+
+## Expected result
+
+Check containers are running and the port mapping:
+```
+$ docker ps
+CONTAINER ID   IMAGE                    COMMAND                  CREATED         STATUS         PORTS                  NAMES

+```
+
+Navigate to `http://localhost:80` in your web browser to access Drupal.
+

+
+Stop and remove the containers
+
+```
+$ docker-compose down
+```
+
+To remove all Gitea data, delete the named volumes by passing the `-v` parameter:
+```
+$ docker-compose down -v
+```
