Service lb policy resource - Name of the service LB policy to be updated. Thearguments in this group can be used to specify the attributes of this resource.(NOTE) Some attributes are not given arguments in this group but can be set inother ways.

To set theproject attribute:

• provide the argumentservice_lb_policy on the command line with afully specified name;
• provide the argument--project on the command line;
• set the propertycore/project.

This must be specified.

SERVICE_LB_POLICY

ID of the service lb policy or fully qualified identifier for the service lbpolicy.

To set theservice_lb_policy attribute:

• provide the argumentservice_lb_policy on the command line.

This positional argument must be specified if any of the other arguments in thisgroup are specified.

--location=LOCATION

The location Id.

To set thelocation attribute:

• provide the argumentservice_lb_policy on the command line with afully specified name;
• provide the argument--location on the command line.

--async

Return immediately, without waiting for the operation in progress to complete.

--auto-capacity-drain

If specified, an unhealthy MIG/NEG will be removed from Global load balancingand traffic routing for the service. A MIG/NEG is considered to be unhealthy ifless than 25% of the instance/endpoints in the MIG/NEG are healthy.autoCapacityDrain will never drain more than 50% of the configured MIGs/NEGs ofa Backend Service.

--description=DESCRIPTION

The description for the service LB policy.

--failover-health-threshold=FAILOVER_HEALTH_THRESHOLD

The percentage threshold that a load balancer will begin to send traffic tofailover backends. If the percentage of endpoints in a MIG/NEG is smaller thanthis value, traffic would be sent to failover backends if possible. This fieldshould be set to a value between 1 and 99. The default value is 50 for Proxylessservice mesh, and 70 for others.

--isolation-config-granularity=ISOLATION_CONFIG_GRANULARITY; default="unspecified"

The granularity of the isolation.ISOLATION_CONFIG_GRANULARITY must be one of:

region

Traffic for this service will be isolated at the nearest cloud region.

unspecified

No isolation is configured for the backend service. Traffic can overflow basedon the load balancing algorithm.

--isolation-config-mode=ISOLATION_CONFIG_MODE; default="unspecified"

The granularity of the isolation.ISOLATION_CONFIG_MODEmust be one of:

nearest

Traffic will be sent to the nearest location.

strict

Traffic will fail if no serving backends are available in the same region as theload balancer.

unspecified

No isolation mode is configured for the backend service.

--load-balancing-algorithm=LOAD_BALANCING_ALGORITHM; default="waterfall-by-region"

The global load balancing algorithm to be used.LOAD_BALANCING_ALGORITHM must be one of:

spray-to-region

Spread the traffic from each client to all the MIGs/NEGs in a region.

spray-to-world

Balance traffic across all backends across the world proportionally based oncapacity.

waterfall-by-region

Direct traffic to the nearest region with endpoints and capacity before spillingover to other regions.

waterfall-by-zone

Attempt to keep traffic in a single zone closest to the client, before spillingover to other zones.
