-```
-
-## Preparations
-
- - Create a new folder for the lab:
-```
-mkdir lab-11
-cd lab-11
-```
-
-## Instructions
-
-- Create a **"docker-compose.yml"** file with the content below:
-
-```
-version: '3.3'
-
-services:
-  db:
-    image: mysql:5.7
-    volumes:
-    - db_data:/var/lib/mysql
-    restart: always
-    environment:
-      MYSQL_ROOT_PASSWORD: somewordpress
-      MYSQL_DATABASE: wordpress
-      MYSQL_USER: admin
-      MYSQL_PASSWORD: wordpress
-
-  wordpress:
-    depends_on:
-    - db
-    image: wordpress:latest
-    ports:
-    - "8000:80"
-    restart: always
-    environment:
-      WORDPRESS_DB_HOST: db:3306
-      WORDPRESS_DB_USER: admin
-      WORDPRESS_DB_PASSWORD: wordpress
-
-volumes:
-  db_data:
-```
- 
- - Start all the environment in detached mode:
-
-```
- docker-compose up -d
-```
- 
- - Wait until docker complete to start the containers, meanwhile let's inspect the wordpress logs:
-
-```
-docker-compose logs -f wordpress
-```
-
- - Check the running containers:
-
-```
-docker-compose ps
-```
-
- - Browse to the wordpress portal:
- 
-```
-http://<Your-Server-IP>:8000
-```
-  
- - Enter to the mysql container:
-   
-```
-docker-compose exec db bin/bash
-```
-
- - Print the environment variable **"MYSQL_USER"** (passed in the yaml file):
-   
-```
-echo $MYSQL_USER
-```
-
- - Exit from the container
-```
-exit
-```
-  
- - Update the mysql image used in the **docker-compose.yml** file to "5.7.24":
-```
-image: mysql:5.7.24
-```
-```
-db:
-  image: mysql:5.7.24
-  volumes:
-  - db_data:/var/lib/mysql
-  restart: always
-  environment:
-    MYSQL_ROOT_PASSWORD: somewordpress
-    MYSQL_DATABASE: wordpress
-    MYSQL_USER: admin
-    MYSQL_PASSWORD: wordpress
-```
-
- - Apply the changes to the running environment:
-
-```
-docker-compose up -d
-```
-  
- - Let's clean our environment (remove the containers defined in the docker-compose file):
-
-```
-docker-compose down
-```
-
- - Note that volumes are not deleted by default, so you can recreate the environment at any time
-
-```
-docker volume ls
-```
-
- - To remove the volumes as well you can use "docker-compose down --volume"
