Tune the proxy service¶

This topic describes how to tune various components of the proxy service.

Constrain the proxy service to multiple dedicated worker nodes:
```
<need-sme-instructions>
```
Adjust the stop signal and grace period, for example, to SIGTERM for the stop signal and ten seconds for the grace period:
```
docker service update --stop-signal=SIGTERM \
--stop-grace-period=10s interlock-proxy
```
Change the action that Swarm takes when an update fails using update-failure-action (the default is pause), for example, to rollback to the previous configuration:
```
docker service update --update-failure-action=rollback \
interlock-proxy
```
Change the amount of time between proxy updates using update-delay (the default is to use rolling updates), for example, setting the delay to thirty seconds:
```
docker service update --update-delay=30s interlock-proxy
```
