Tune the proxy service

Constrain the proxy service to multiple dedicated worker nodes

Refer to Proxy service constraints for information on how to constrain the proxy service to multiple dedicated worker nodes.

Stop

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:

$> 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:

$> 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:

$> docker service update --update-delay=30s interlock=proxy
