# docker based deployment
|
||
|
|
|
||
|
|
## Prerequisites
|
||
|
|
|
||
|
|
* Docker 1.12.x or later (*Docker Swarm Mode*)
|
||
|
|
|
||
|
|
## Setup
|
||
|
|
|
||
|
|
First decide which nodes you are going to run coredns on and set appropriate
|
||
|
|
labels on your nodes. I use `iface=extern` as labels on nodes with external
|
||
|
|
facing interfaces and `iface=intern` for internal facing nodes.
|
||
|
|
|
||
|
|
```#!bash
|
||
|
|
$ docker node inspect node1 | jq '.[0].Spec.Labels'
|
||
|
|
{
|
||
|
|
"iface": "extern"
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
## Deploy
|
||
|
|
|
||
|
|
Connect to a "manager" node:
|
||
|
|
(*I use `docker-machine` for this*)
|
||
|
|
|
||
|
|
```#!bash
|
||
|
|
$ eval $(docker-machine env node1)
|
||
|
|
$ docker stack deploy -c dns.yml dns
|
||
|
|
```
|
||
|
|
|
||
|
|
## Verify
|
||
|
|
|
||
|
|
Verify your setup works:
|
||
|
|
|
||
|
|
```#!bash
|
||
|
|
$ dig @<node1> google.com IN A +short
|
||
|
|
```
