<!-- END MUNGE: EXAMPLE newrelic-daemonset.yaml -->
The daemonset instructs Kubernetes to spawn pods on each node, mapping /dev/, /run/, /sys/, and /var/log to the container. It also maps the secrets we set up earlier to /etc/kube-newrelic/config, and sources them in the startup script, configuring the agent properly.
#### DaemonSet customization
- To include a custom hostname prefix (or other per-container environment variables that can be generated at run-time), you can modify the DaemonSet `command` value:
```
command: [ "bash", "-c", "source /etc/kube-newrelic/config && export NRSYSMOND_hostname=mycluster-$(hostname) && /usr/sbin/nrsysmond -E -F" ]
```
When the New Relic agent starts, `NRSYSMOND_hostname` is set using the output of `hostname` with `mycluster` prepended.
### Known issues
It's a bit cludgy to define the environment variables like we do here in these config files. There is [another issue](https://github.com/kubernetes/kubernetes/issues/4710) to discuss adding mapping secrets to environment variables in Kubernetes.
