Viewable with

```
docker inspect --format='{{ json .ContainerConfig.Labels }} <tag>
```

Labels can be queried for running containers too:

```
docker ps --format "table {{.ID}}\t{{.Labels}}"
```

Ultimately, this convention is useful to find out the build information
for the Docker image without mutating the image contents.
