# Dory's dnsmasq container
## What is this?
[Dory](https://github.com/FreedomBen/dory) uses this container to provide the dnsmasq
services in conjunction with an nginx-proxy. It's a very lightweight container built
on Alpine Linux (based off of [andyshinn/dnsmasq](https://hub.docker.com/r/andyshinn/dnsmasq/).
See the [dory](https://github.com/FreedomBen/dory) project page for more info.
## How do I use it?
### A single TLD
You can use this container in your project, or as a standalone utility if you'd like.
Here's how to fire it up.
```
docker run -p 53:53/tcp -p 53:53/udp --cap-add=NET_ADMIN freedomben/dory-dnsmasq:1.0.0 [] []
```
So if you wanted all queries against domain "docker" to be routed to IP 3.3.3.3:
```
docker run -p 53:53/tcp -p 53:53/udp --cap-add=NET_ADMIN freedomben/dory-dnsmasq:1.0.0 docker 3.3.3.3
```
If you'd rather extend it to bake in your defaults, here's an example:
```
FROM freedomben/dory-dnsmasq
CMD["docker", "3.3.3.3"]
```
### Multiple TLDs
You can have more than one TLD if you prefer. Use the container the same way as with a single TLD, but add each domain and ip as extra args.
```
docker run -p 53:53/tcp -p 53:53/udp --cap-add=NET_ADMIN freedomben/dory-dnsmasq:1.0.0 [] [] [] []
```
So if you wanted all queries against domain "docker" to be routed to IP 3.3.3.3, and dev to be routed to 4.4.4.4:
```
docker run -p 53:53/tcp -p 53:53/udp --cap-add=NET_ADMIN freedomben/dory-dnsmasq:1.0.0 docker 3.3.3.3 dev 4.4.4.4
```
The domains can go to the same IP. You just have to repeat it. Say you wanted both to go to 3.3.3.3:
```
docker run -p 53:53/tcp -p 53:53/udp --cap-add=NET_ADMIN freedomben/dory-dnsmasq:1.0.0 docker 3.3.3.3 dev 3.3.3.3
```
### Wildcard
You can have all domain names that are not answered from /etc/hosts or DHCP be resolved to a specific address by using a `#` as the domain. So to have all requests be resolved to 4.4.4.4:
```
docker run -p 53:53/tcp -p 53:53/udp --cap-add=NET_ADMIN freedomben/dory-dnsmasq:1.0.0 '#' 4.4.4.4
```
*NOTE: You have to put the # in quotes otherwise bash will think it's a comment character*
