# Wordpress with Docker Compose
This page shows you how to deploy a sample [WordPress][wordpress] site using
[Docker Compose][docker-compose].
### Before you begin
[Follow these instructions][docker-install] to install runsc with Docker. This
document assumes that Docker and Docker Compose are installed and the runtime
name chosen for gVisor is `runsc`.
### Configuration
We'll start by creating the `docker-compose.yaml` file to specify our services.
We will specify two services, a `wordpress` service for the Wordpress Apache
server, and a `db` service for MySQL. We will configure Wordpress to connect to
MySQL via the `db` service host name.
> **Note:** Docker Compose uses it's own network by default and allows services
> to communicate using their service name. Docker Compose does this by setting
> up a DNS server at IP address 127.0.0.11 and configuring containers to use it
> via [resolv.conf][resolv.conf]. This IP is not addressable inside a gVisor
> sandbox so it's important that we set the DNS IP address to the alternative
> `8.8.8.8` and use a network that allows routing to it. See
> [Networking in Compose][compose-networking] for more details.
> **Note:** The `runtime` field was removed from services in the 3.x version of
> the API in versions of docker-compose < 1.27.0. You will need to write your
> `docker-compose.yaml` file using the 2.x format or use docker-compose >=
> 1.27.0. See this [issue](https://github.com/docker/compose/issues/6239) for
> more details.
```yaml
version: '2.3'
services:
db:
image: mysql:5.7
volumes:
- db_data:/var/lib/mysql
restart: always
environment:
MYSQL_ROOT_PASSWORD: somewordpress
MYSQL_DATABASE: wordpress
MYSQL_USER: wordpress
MYSQL_PASSWORD: wordpress
# All services must be on the same network to communicate.
network_mode: "bridge"
wordpress:
depends_on:
- db
# When using the "bridge" network specify links.
links:
- db
image: wordpress:latest
ports:
- "8080:80"
restart: always
environment:
WORDPRESS_DB_HOST: db:3306
WORDPRESS_DB_USER: wordpress
WORDPRESS_DB_PASSWORD: wordpress
WORDPRESS_DB_NAME: wordpress
# Specify the dns address if needed.
dns:
- 8.8.8.8
# All services must be on the same network to communicate.
network_mode: "bridge"
# Specify the runtime used by Docker. Must be set up in
# /etc/docker/daemon.json.
runtime: "runsc"
volumes:
db_data: {}
```
Once you have a `docker-compose.yaml` in the current directory you can start the
containers:
```bash
docker-compose up
```
Once the containers have started you can access wordpress at
http://localhost:8080.
Congrats! You now how a working wordpress site up and running using Docker
Compose.
