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 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 --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

Direct from Docker

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