+# 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.
