Nomad server 0.3.2
Full Description

docker-nomad

##Nomad Agent in Docker
This project is a Docker container for Nomad that is pre-configured Nomad Agent made specifically to work in the Docker ecosystem.

##Getting the container
The container is very small and based on Alpine base image.

docker pull aatarasoff/nomad           //base image
docker pull aatarasoff/nomad-server    //server pre-configured image
docker pull aatarasoff/nomad-client    //client pre-configured image

##Using the container

###Standalone

docker run -d --net host --name nomad \
  -p 4646:4646 -p 4646:4646/udp \
  -p 4647:4647 -p 4647:4647/udp \
  -p 4648:4648 -p 4648:4648/udp \
  -v /var/run/docker.sock:/var/run/docker.sock \
  aatarasoff/nomad -dev -bind=<your_binding_ip_address>

Standalone configuration is recommended for developing only.

###Clustering
First you need to run three server nodes on different machines. Each node is running like:

docker run -d --net host --name nomad \
  -p 4646:4646 -p 4646:4646/udp \
  -p 4647:4647 -p 4647:4647/udp \
  -p 4648:4648 -p 4648:4648/udp \
  -v /var/run/docker.sock:/var/run/docker.sock \
  aatarasoff/nomad-server -bind=<your_binding_ip_address>

Next step is joining nodes number two and three to node number one:

docker exec nomad nomad server-join -address http://<node2_ip>:4646 <node1_ip>:4648
docker exec nomad nomad server-join -address http://<node3_ip>:4646 <node1_ip>:4648

Or you may use HTTP API for this.
Next step is launch clients:

docker run -d --net host --name nomad \
  -p 4646:4646 -p 4646:4646/udp \
  -p 4647:4647 -p 4647:4647/udp \
  -p 4648:4648 -p 4648:4648/udp \
  -v /var/run/docker.sock:/var/run/docker.sock \
  aatarasoff/nomad-client -bind=<your_binding_ip_address> -servers <node1_ip>:4647

Check that client nodes is available:

curl <node1_ip>:4646/v1/nodes

###Run example task
Try your configuration with example task on one of the server nodes:

docker exec nomad nomad init
docker exec nomad nomad run -address=http://<node_ip>:4646 example.nomad

Check that redis container is launched on client nodes.

##Enjoy!
