# 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), as a tree in the terminal, or in a short summary.
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.
![](sample/containers.png "Container")
## Images
Image info is visualized with lines indicating parent images:
![](sample/images.png "Image")
Or in short form:
```
nate/mongodb: latest
redis: latest
ubuntu: 12.04, precise, 12.10, quantal, 13.04, raring
```
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 --tree
$ curl -s http://localhost:4243/containers/json?all=1 | dockviz containers --dot | dot -Tpng -o containers.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
$ echo -e "GET /containers/json?all=1 HTTP/1.0\r\n" | nc -U /var/run/docker.sock | tail -n +5 | dockviz containers --dot | dot -Tpng -o containers.png
```
GNU netcat doesn't support `-U` (UNIX socket) flag, so OpenBSD variant can be used.
## Direct from Docker
Someday soon the Docker command line will allow dumping the image and container JSON directly.
