Follow @dockviz for updates.
This command takes Docker image and container information and presents in different ways, to help you understand what's going on inside the system.
- Install dockviz. Either:
- Download the latest release.
- Set up an alias to run it from the (5.8 MB) docker image:
alias dockviz="docker run -it --rm -v /var/run/docker.sock:/var/run/docker.sock nate/dockviz"
- Visualize images by running
dockviz images -t, which has similar output todocker images -t.
Image can be visualized as Graphviz, or as a tree or short summary in the terminal. Only Graphviz output has been implemented for containers.
Currently, containers are visualized with labelled lines for links. Containers that aren't running are greyed out.
$ dockviz containers -d | dot -Tpng -o containers.png
Image info is visualized with lines indicating parent images:
$ dockviz images -d | dot -Tpng -o images.png
OR
$ dockviz images --dot | dot -Tpng -o images.png
$ dockviz images -d -l | dot -Tpng -o images.png
OR
$ dockviz images --dot --only-labelled | dot -Tpng -o images.png
Or in short form:
$ dockviz images -s
nate/mongodb: latest
redis: latest
ubuntu: 12.04, precise, 12.10, quantal, 13.04, raring
Or as a tree in the terminal:
$ dockviz images -t

Dockviz supports connecting to the Docker daemon directly. It defaults to unix:///var/run/docker.sock, but respects the following as well:
- The
DOCKER_HOST,DOCKER_CERT_PATH, andDOCKER_TLS_VERIFYenvironment variables, as set up by boot2docker or docker-machine. - Command line arguments (e.g.
--tlscacert), like those that Docker itself supports.
Dockviz also supports receiving Docker image or container json data on standard input.
$ 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
$ echo -e "GET /images/json?all=1 HTTP/1.0\r\n" | nc -U /var/run/docker.sock | sed '1,/^[[:space:]]*$/d' | dockviz images --tree
$ echo -e "GET /containers/json?all=1 HTTP/1.0\r\n" | nc -U /var/run/docker.sock | sed '1,/^[[:space:]]*$/d' | dockviz containers --dot | dot -Tpng -o containers.png
$ echo -e "GET /images/json?all=1 HTTP/1.0\r\n" | nc -U /var/run/docker.sock | sed '1,/^[[:space:]]*$/d' | docker run -i nate/dockviz images --tree
$ echo -e "GET /containers/json?all=1 HTTP/1.0\r\n" | nc -U /var/run/docker.sock | sed '1,/^[[:space:]]*$/d' | docker run -i nate/dockviz containers --dot | dot -Tpng -o containers.png
Note: GNU netcat doesn't support -U (UNIX socket) flag, so OpenBSD variant can be used.
