Closes-Bug: #1851609 Change-Id: I7a4056680d8453b2ef2dcc853437a0ec4b3e8044 ** Changed in: neutron Status: In Progress => Fix Released -- You received this bug notification because you are a member of Yahoo! Engineering Team, which is subscribed to neutron. https://bugs.launchpad.net/bugs/1851609 Title: Add an option for graceful l3 agent shutdown Status in neutron: Fix Released Bug description: If KillMode in systemd config of a neutron l3 agent service is set to 'process' - it will not kill child processes on main service stop - this is useful when we don't want data-plane downtime on agent stop/restart due to keepalived exit. However in some cases graceful cleanup on l3 agent shutdown is needed - like with containerised control plane, when kubernetes kills l3-agent pod, it automatically kills its children (keepalived processes) in non-graceful way, so that keepalived does not clear VIPs. This leads to a situation when same VIP is present on different nodes and hence to long downtime. The proposal is to add a new l3 agent config so that it handles stop (SIGTERM) by deleting all routers. For HA routers it results in graceful keepalived shutdown.
