# go-coredns-nomad
coredns with nomad plugin for service discovery. This repository will build a docker container
with coredns and the nomad plugin.
## Using the container
In order to run this container, and have service discovery
work on port 1053, you need to pass in the following environment variables:
* `NOMAD_ADDR` - the address of the nomad server
* `NOMAD_TOKEN` - the token to use to query the nomad server
* `NOMAD_TTL` - the TTL for the DNS records, in seconds
For example:
```sh
docker run --name coredns-nomad --rm -p 1053:53 \
--env NOMAD_ADDR=http://nomad:4646/ \
--env NOMAD_TOKEN=XXXXXX \
--env NOMAD_TTL=10 \
ghcr.io/mutablelogic/coredns-nomad:v1.11.1
```
When you want to test it using dig, query `..nomad`. For example,
```sh
dig +tcp -p 1053 @localhost service.default.nomad
```
## Building the container
You can use the pre-built container from the GitHub Container Registry (for arm64 or amd64 on Linux),
or you can build it yourself.
```sh
git clone [email protected]:mutablelogic/go-coredns-nomad.git
cd go-coredns-nomad
docker build \
--tag ${REGISTRY}/${USERNAME}/coredns-nomad:v1.11.1 \
--build-arg ARCH=$(arch) \
--build-arg PLATFORM=$(uname -s | tr '[:upper:]' '[:lower:]') \
--build-arg VERSION=v1.11.1 \
-f etc/docker/Dockerfile .
```
