ComputeRegionBackendServiceRegionBackendServiceFailoverPolicy class

failover_policy block — only meaningful for Internal Passthrough NLBs. Backends are split into primary / failover pools (see ComputeRegionBackendServiceRegionBackendServiceBackend.failover); when the primary pool's healthy fraction drops below failoverRatio, traffic is shifted to the failover pool.

Constructors

ComputeRegionBackendServiceRegionBackendServiceFailoverPolicy({TfArg<bool>? disableConnectionDrainOnFailover, TfArg<bool>? dropTrafficIfUnhealthy, TfArg<double>? failoverRatio})

const

Properties

disableConnectionDrainOnFailover → TfArg<bool>?

If true, connections to the old active pool are not drained on failover. Can be set to true only when protocol is TCP.

final

dropTrafficIfUnhealthy → TfArg<bool>?

If true, drop traffic when no healthy VM is detected in either pool. If false, traffic is spread across all VMs in the primary group as a best-effort fallback.

final

failoverRatio → TfArg<double>?

Health-fraction threshold (0.0-1.0) that triggers failover. L4 LBs only.
