* Download the [latest release](https://github.com/justone/dockviz/releases).
|
||||
* Set up an alias to run it from the (5.8 MB) docker image:
|
||||
|
||||
```
|
||||
# if docker client using local unix socket
|
||||
alias dockviz="docker run -it --rm -v /var/run/docker.sock:/var/run/docker.sock nate/dockviz"
|
||||
|

# if docker client using tcp
|
||||
alias dockviz="docker run -it --rm -e DOCKER_HOST='tcp://127.0.0.1:2375' nate/dockviz"
|

```
|
||||
|
||||
```
|
||||
alias dockviz="docker run --rm -v /var/run/docker.sock:/var/run/docker.sock nate/dockviz"
|
||||
```
|
||||
2. Visualize images by running `dockviz images -t`, which has similar output to `docker images -t`.
|
||||
* Image can be visualized as [Graphviz](http://www.graphviz.org), or as a tree or short summary in the terminal. Only Graphviz output has been implemented for containers.
|
||||
* If you would like to visualize outside the container you will have to install [Graphviz](http://www.graphviz.org) first.
|
||||
|
||||
```
|
||||
apt-get update && apt-get install graphviz
|
||||
```
|
||||
|

or

|

```

brew update && brew install graphviz

# Running
|
||||
|
||||
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`, and `DOCKER_TLS_VERIFY` environment variables, as set up by [boot2docker](http://boot2docker.io/) or [docker-machine](https://docs.docker.com/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 --stdin images --tree
|
||||
$ curl -s http://localhost:4243/containers/json?all=1 | dockviz --stdin containers --dot | dot -Tpng -o containers.png

Note: GNU netcat doesn't support `-U` (UNIX socket) flag, so OpenBSD variant can be used.
