# dockviz

Visualizing Docker Data

This command takes the raw Docker JSON and visualizes it in various ways.

For image information, output can be formatted as
[Graphviz](http://www.graphviz.org) or as a tree in the terminal.

For container information, only Graphviz output has been implemented.

# Examples

## Containers

Currently, containers are visualized with labeled lines for links.  Containers that aren't running are greyed out.

## Images

Image info is visualized with lines indicating parent images:

Or as a tree in the terminal:

# Running

## TCP

When docker is listening on the TCP port:

```
$ curl -s http://localhost:4243/images/json?all=1 | dockviz images --dot | dot -Tpng -o images.png
```

## Socket

When docker is listening on the socket:

```
echo -e "GET /images/json?all=1 HTTP/1.0\r\n" | nc -U /var/run/docker.sock | tail -n +5 | dockviz images --tree
```

## Direct from Docker

Someday soon the Docker command line will allow dumping the image and container JSON directly.
