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.
