# circus-scoreboard
Scoreboard displaying the rankings of all companions in the swarm
## Function
This container displays a scoreboard ranking the individual companion
containers. The container should simply get a list of all running containers
using the docker socket (this is just an idea) and access a stats endpoint. The
stats endpoint optimally exposes the name of the user the companion container
belongs to and the amount of points the user has.
## Setup
First of all, make sure all the companion containers are part of the circus
network. If you haven't defined a circus network, you can do so by running
`docker network create circus` and running the companion containers using the
`--net circus` flag.
Running the scoreboard is done by first building the docker image:
```
$ docker build . -t circus-scoreboard
...
Successfully tagged circus-scoreboard:latest
```
... and then running the image:
```
docker run --rm -v /var/run/docker.sock:/var/run/docker.sock --net circus circus-scoreboard:latest
```
There are a few things to take note of:
- The docker socket is mounted to enable the container to find the companion
containers.
- The container is inside of the circus network as are the companion containers.
This makes it possible to communicate inbetween the containers.
