### Advanced: Advertising additional pilot attributes

You can put arbitrary additional attributes in the machine ads that the pilot advertises to the OSPool.
These attributes will show up when users run `condor_status -l` against your pilot.
This could be useful for advertising something about the way the pilot was provisioned.
To do this, volume-mount a file containing `key=value` pairs to `/etc/osg/extra-attributes.cfg`.
Keys must be valid classad attribute names and values must be valid classad expressions.
Multi-line strings are not supported.
A line starting with `#` will be treated as a comment.
For example:

```
# The Kubernetes namespace this pod is running under
KUBERNETES_NAMESPACE = "path-osgdev"
# The deployment for this pilot
KUBERNETES_DEPLOYMENT = "osgvo-docker-pilot-gpu"
```
