+# Tuning the proxy service
+
+## Constraining the proxy service to multiple dedicated worker nodes
+Refer to [Proxy service constraints](../deploy/production.md) for information on how to constrain the proxy service to multiple dedicated worker nodes.
+
+## Stopping
+To adjust the stop signal and period, use the `stop-signal` and `stop-grace-period` settings.  For example,
+to set the stop signal to `SIGTERM` and grace period to ten (10) seconds, use the following command:
+
+```bash
+$> docker service update --stop-signal=SIGTERM --stop-grace-period=10s interlock-proxy
+```
+
+## Update actions
+In the event of an update failure, the default Swarm action is to "pause".  This prevents Interlock updates from happening
+without operator intervention.  You can change this behavior using the `update-failure-action` setting.  For example,
+to automatically rollback to the previous configuration upon failure, use the following command:
+
+```bash
+$> docker service update --update-failure-action=rollback interlock-proxy
+```
+
+## Update interval
+By default, Interlock configures the proxy service using rolling update. For more time between proxy
+updates, such as to let a service settle, use the `update-delay` setting.  For example, if you want to have
+thirty (30) seconds between updates, use the following command:
+
+```bash
+$> docker service update --update-delay=30s interlock=proxy
+```
