The Docker Swarm Monitor shows running containers (eg. replicas of a swarm service) with the Blinkt! LED strip.

 ```bash

 docker run -v /sys:/sys -v /var/run/docker.sock:/var/run/docker.sock monitor

 ```

## Swarm Mode Demo

```

docker service create --name monitor \

--mode global --restart-condition any --mount type=bind,src=/sys,dst=/sys --mount type=bind,src=/var/run/docker.sock,dst=/var/run/docker.sock \

stefanscherer/monitor:1.1.0

```

Create a service

```

docker service create --name whoami stefanscherer/whoami:1.1.0

```

Scale service up and down

```

docker service scale whoami=4

docker service scale whoami=16

docker service scale whoami=32

```
