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 --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.
