## Wordpress with MySQL
This example defines one of the basic setups for Wordpress. More details on how this works can be found on the official [wordpress image page](https://hub.docker.com/_/wordpress).
Project structure:
```
.
├── docker-compose.yaml
└── README.md
```
[_docker-compose.yaml_](docker-compose.yaml)
```
services:
db:
image: mysql:8.0.19
...
wordpress:
image: wordpress:latest
ports:
- 80:80
restart: always
...
```
When deploying this setup, docker-compose maps the wordpress 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 "wordpress-mysql_default" with the default driver
Creating volume "wordpress-mysql_db_data" with default driver
...
Creating wordpress-mysql_db_1 ... done
Creating wordpress-mysql_wordpress_1 ... done
```
## Expected result
Check containers are running and the port mapping:
```
$ docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
5fbb4181a069 wordpress:latest "docker-entrypoint.s…" 35 seconds ago Up 34 seconds 0.0.0.0:80->80/tcp wordpress-mysql_wordpress_1
e0884a8d444d mysql:8.0.19 "docker-entrypoint.s…" 35 seconds ago Up 34 seconds 3306/tcp, 33060/tcp wordpress-mysql_db_1
```
Navigate to `http://localhost:80` in your web browser to access Wordpress.

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
```
