Return Values

Common return values are documented here, the following are the fields unique to this module:

Key					Returned	Description
resources complex					always	List of resources
	affinityCookieTtlSec integer				success	Lifetime of cookies in seconds if session_affinity is GENERATED_COOKIE. If set to 0, the cookie is non-persistent and lasts only until the end of the browser session (or equivalent). The maximum allowed value for TTL is one day. When the load balancing scheme is INTERNAL, this field is not used.
	backends complex				success	The set of backends that serve this BackendService.
		balancingMode string			success	Specifies the balancing mode for this backend. For global HTTP(S) or TCP/SSL load balancing, the default is UTILIZATION. Valid values are UTILIZATION, RATE (for HTTP(S)) and CONNECTION (for TCP/SSL).
		capacityScaler string			success	A multiplier applied to the group's maximum servicing capacity (based on UTILIZATION, RATE or CONNECTION). Default value is 1, which means the group will serve up to 100% of its configured capacity (depending on balancingMode). A setting of 0 means the group is completely drained, offering 0% of its available Capacity. Valid range is [0.0,1.0].
		description string			success	An optional description of this resource. Provide this property when you create the resource.
		group string			success	The fully-qualified URL of an Instance Group or Network Endpoint Group resource. In case of instance group this defines the list of instances that serve traffic. Member virtual machine instances from each instance group must live in the same zone as the instance group itself. No two backends in a backend service are allowed to use same Instance Group resource. For Network Endpoint Groups this defines list of endpoints. All endpoints of Network Endpoint Group must be hosted on instances located in the same zone as the Network Endpoint Group. Backend services cannot mix Instance Group and Network Endpoint Group backends. Note that you must specify an Instance Group or Network Endpoint Group resource using the fully-qualified URL, rather than a partial URL.
		maxConnections integer			success	The max number of simultaneous connections for the group. Can be used with either CONNECTION or UTILIZATION balancing modes. For CONNECTION mode, either maxConnections or one of maxConnectionsPerInstance or maxConnectionsPerEndpoint, as appropriate for group type, must be set.
		maxConnectionsPerEndpoint integer			success	The max number of simultaneous connections that a single backend network endpoint can handle. This is used to calculate the capacity of the group. Can be used in either CONNECTION or UTILIZATION balancing modes. For CONNECTION mode, either maxConnections or maxConnectionsPerEndpoint must be set.
		maxConnectionsPerInstance integer			success	The max number of simultaneous connections that a single backend instance can handle. This is used to calculate the capacity of the group. Can be used in either CONNECTION or UTILIZATION balancing modes. For CONNECTION mode, either maxConnections or maxConnectionsPerInstance must be set.
		maxRate integer			success	The max requests per second (RPS) of the group. Can be used with either RATE or UTILIZATION balancing modes, but required if RATE mode. For RATE mode, either maxRate or one of maxRatePerInstance or maxRatePerEndpoint, as appropriate for group type, must be set.
		maxRatePerEndpoint string			success	The max requests per second (RPS) that a single backend network endpoint can handle. This is used to calculate the capacity of the group. Can be used in either balancing mode. For RATE mode, either maxRate or maxRatePerEndpoint must be set.
		maxRatePerInstance string			success	The max requests per second (RPS) that a single backend instance can handle. This is used to calculate the capacity of the group. Can be used in either balancing mode. For RATE mode, either maxRate or maxRatePerInstance must be set.
		maxUtilization string			success	Used when balancingMode is UTILIZATION. This ratio defines the CPU utilization target for the group. The default is 0.8. Valid range is [0.0, 1.0].
	cdnPolicy complex				success	Cloud CDN configuration for this BackendService.
		cacheKeyPolicy complex			success	The CacheKeyPolicy for this CdnPolicy.
			includeHost boolean		success	If true requests to different hosts will be cached separately.
			includeProtocol boolean		success	If true, http and https requests will be cached separately.
			includeQueryString boolean		success	If true, include query string parameters in the cache key according to query_string_whitelist and query_string_blacklist. If neither is set, the entire query string will be included. If false, the query string will be excluded from the cache key entirely.
			queryStringBlacklist list / elements=string		success	Names of query string parameters to exclude in cache keys. All other parameters will be included. Either specify query_string_whitelist or query_string_blacklist, not both. '&' and '=' will be percent encoded and not treated as delimiters.

		signedUrlCacheMaxAgeSec integer			success	Maximum number of seconds the response to a signed URL request will be considered fresh, defaults to 1hr (3600s). After this time period, the response will be revalidated before being served. When serving responses to signed URL requests, Cloud CDN will internally behave as though all responses from this backend had a "Cache-Control: public, max-age=[TTL]" header, regardless of any existing Cache-Control header. The actual headers served in responses will not be altered.
	circuitBreakers complex				success	Settings controlling the volume of connections to a backend service. This field is applicable only when the load_balancing_scheme is set to INTERNAL_SELF_MANAGED.

This load balancing policy is applicable only for HTTP connections. The affinity to a particular destination host will be lost when one or more hosts are added/removed from the destination service. This field specifies parameters that control consistent hashing. This field only applies if the load_balancing_scheme is set to INTERNAL_SELF_MANAGED. This field is only applicable when locality_lb_policy is set to MAGLEV or RING_HASH.

	loadBalancingScheme string				success	Indicates whether the backend service will be used with internal or external load balancing. A backend service created for one type of load balancing cannot be used with the other.
	localityLbPolicy string				success	The load balancing algorithm used within the scope of the locality. The possible values are - * ROUND_ROBIN - This is a simple policy in which each healthy backend is selected in round robin order. * LEAST_REQUEST - An O(1) algorithm which selects two random healthy hosts and picks the host which has fewer active requests. * RING_HASH - The ring/modulo hash load balancer implements consistent hashing to backends. The algorithm has the property that the addition/removal of a host from a set of N hosts only affects 1/N of the requests. * RANDOM - The load balancer selects a random healthy host. * ORIGINAL_DESTINATION - Backend host is selected based on the client connection metadata, i.e., connections are opened to the same address as the destination address of the incoming connection before the connection was redirected to the load balancer. * MAGLEV - used as a drop in replacement for the ring hash load balancer. Maglev is not as stable as ring hash but has faster table lookup build times and host selection times. For more information about Maglev, refer to https://ai.google/research/pubs/pub44824 This field is applicable only when the load_balancing_scheme is set to INTERNAL_SELF_MANAGED.
	logConfig complex				success	This field denotes the logging options for the load balancer traffic served by this backend service. If logging is enabled, logs will be exported to Stackdriver.

	name string				success	Name of the resource. Provided by the client when the resource is created. The name must be 1-63 characters long, and comply with RFC1035. Specifically, the name must be 1-63 characters long and match the regular expression `[a-z]([-a-z0-9]*[a-z0-9])?` which means the first character must be a lowercase letter, and all following characters must be a dash, lowercase letter, or digit, except the last character, which cannot be a dash.
	outlierDetection complex				success	Settings controlling eviction of unhealthy hosts from the load balancing pool. This field is applicable only when the load_balancing_scheme is set to INTERNAL_SELF_MANAGED.
		baseEjectionTime complex			success	The base time that a host is ejected for. The real time is equal to the base time multiplied by the number of times the host has been ejected. Defaults to 30000ms or 30s.

		enforcingConsecutiveErrors integer			success	The percentage chance that a host will be actually ejected when an outlier status is detected through consecutive 5xx. This setting can be used to disable ejection or to ramp it up slowly. Defaults to 100.
		enforcingConsecutiveGatewayFailure integer			success	The percentage chance that a host will be actually ejected when an outlier status is detected through consecutive gateway failures. This setting can be used to disable ejection or to ramp it up slowly. Defaults to 0.
		enforcingSuccessRate integer			success	The percentage chance that a host will be actually ejected when an outlier status is detected through success rate statistics. This setting can be used to disable ejection or to ramp it up slowly. Defaults to 100.
		interval complex			success	Time interval between ejection sweep analysis. This can result in both new ejections as well as hosts being returned to service. Defaults to 10 seconds.
			nanos integer		success	Span of time that's a fraction of a second at nanosecond resolution. Durations less than one second are represented with a 0 `seconds` field and a positive `nanos` field. Must be from 0 to 999,999,999 inclusive.

		successRateRequestVolume integer			success	The minimum number of total requests that must be collected in one interval (as defined by the interval duration above) to include this host in success rate based outlier detection. If the volume is lower than this setting, outlier detection via success rate statistics is not performed for that host. Defaults to 100.
		successRateStdevFactor integer			success	This factor is used to determine the ejection threshold for success rate outlier ejection. The ejection threshold is the difference between the mean success rate, and the product of this factor and the standard deviation of the mean success rate: mean - (stdev * success_rate_stdev_factor). This factor is divided by a thousand to get a double. That is, if the desired factor is 1.9, the runtime value should be 1900. Defaults to 1900.
	portName string				success	Name of backend port. The same name should appear in the instance groups referenced by this service. Required when the load balancing scheme is EXTERNAL.
	protocol string				success	The protocol this BackendService uses to communicate with backends. The default is HTTP. NOTE: HTTP2 is only valid for beta HTTP/2 load balancer types and may result in errors if used with the GA API.
	securityPolicy string				success	The security policy associated with this backend service.
	sessionAffinity string				success	Type of session affinity to use. The default is NONE. Session affinity is not applicable if the protocol is UDP.
	timeoutSec integer				success	How many seconds to wait for the backend before considering it a failed request. Default is 30 seconds. Valid range is [1, 86400].
