Using runtimecfg render for keepalived has the issue that on 1.x keepalived versions there's no dynamic interfaces and in case the interface changes, keepalived will stop doing its job. Thanks to dynkeepalived, it is now possible to have it monitor the interface and dynamically send a reload to a unix socket that can be used to trigger a keepalived reload in the keepalived container. This is meant to be used from a side-car to the keepalived pod. Signed-off-by: Antoni Segura Puimedon <antoni@redhat.com>

Verified with success that the IP was moved to brext and the VIPs did as well. The downtime for reconfiguration of the interfaces was of about 90seconds. |
