# Example dnsmasq setup
# Example CapRover Definition File
```
apt update && apt -y install dnsmasq
echo address=/mirrors.ubuntu.com/172.17.0.1 > /etc/dnsmasq.d/ubuntu-mirror-local
{
"schemaVersion": 2,
"imageName": "sneak/ubuntumirror:latest"
}
```
Then, just add `--dns 172.17.0.1` to your /etc/default/docker opts
and bounce the docker daemon. Future containers will talk to your local
mirror.
