ImageWolf - Fast Distribution of Docker Images on Clusters

==========================================================

ImageWolf is a PoC that provides a blazingly fast way to get Docker images

loaded onto your cluster, allowing updates to be pushed out quicker.

ImageWolf works alongside existing registries such as the Docker Hub, Quay.io

as well as self-hosted registries.

The PoC for ImageWolf uses the BitTorrent protocol spread images around the

cluster as they are pushed.

## Getting Started

ImageWolf is currently alpha software and intended as a PoC - please don't run it in

production!

### Docker Swarm Mode

To start ImageWolf, run the following on your Swarm master:

```

docker network create -d overlay --attachable wolf

docker service create --network wolf --name imagewolf --mode global \

       --mount type=bind,src=/var/run/docker.sock,dst=/var/run/docker.sock \

       containersol/imagewolf

```

The ImageWolf service is now running on all nodes in our cluster.

The next step is to link ImageWolf with a registry. Whenever an image is pushed to

the registry, ImageWolf will immediately pull it and distribute across all the

nodes. To set up a private registry linked to ImageWolf:

```

# First find the id of the ImageWolf task running on this node

# This should work, but is a bit of a hack

TASK=$(docker ps -f name="imagewolf." --format {{.ID}})

# Configuration for the notification endpoint

export REGISTRY_NOTIFICATIONS_ENDPOINTS=$(cat <
