Resource: ServiceA Service resource is a logical component of an application that can share state and communicate in a secure fashion with other services. For example, an application that handles customer requests might include separate services to handle tasks such as backend data analysis or API requests from mobile devices. Each service has a collection of versions that define a specific set of code used to implement the functionality of that service.

"networkSettings": {

} Fields name
string
Full path to the Service resource in the API. Example: apps/myapp/services/default.
Note: This field is used in responses only. Any value specified here in a request is ignored.
id
string
Relative name of the service within the application. Example: default.
Note: This field is used in responses only. Any value specified here in a request is ignored.
split
object (TrafficSplit)
Mapping that defines fractional HTTP traffic diversion to different versions within the service.
labels
map (key: string, value: string)
A set of labels to apply to this service. Labels are key/value pairs that describe the service and all resources that belong to it (e.g., versions). The labels can be used to search and group resources, and are propagated to the usage and billing reports, enabling fine-grain analysis of costs. An example of using labels is to tag resources belonging to different environments (e.g., "env=prod", "env=qa").
Label keys and values can be no longer than 63 characters and can only contain lowercase letters, numeric characters, underscores, dashes, and international characters. Label keys must start with a lowercase letter or an international character. Each service can have at most 32 labels.
An object containing a list of "key": value pairs. Example: { "name": "wrench", "mass": "1.3kg", "count": "3" }.
networkSettings
object (NetworkSettings)
Ingress settings for this service. Will apply to all versions.
TrafficSplitTraffic routing configuration for versions within a single service. Traffic splits define how traffic directed to the service is assigned to versions.
JSON representation{
"shardBy": enum (ShardBy),
"allocations": {
string: number,
...
}
} Fields shardBy
enum (ShardBy)
Mechanism used to determine which version a request is sent to. The traffic selection algorithm will be stable for either type until allocations are changed.
allocations
map (key: string, value: number)
Mapping from version IDs within the service to fractional (0.000, 1] allocations of traffic for that version. Each version can be specified only once, but some versions in the service may not have any traffic allocation. Services that have traffic allocated cannot be deleted until either the service is deleted or their traffic allocation is removed. Allocations must sum to 1. Up to two decimal place precision is supported for IP-based splits and up to three decimal places is supported for cookie-based splits.
An object containing a list of "key": value pairs. Example: { "name": "wrench", "mass": "1.3kg", "count": "3" }.
Available sharding mechanisms.
EnumsUNSPECIFIED Diversion method unspecified. COOKIE Diversion based on a specially named cookie, "GOOGAPPUID." The cookie must be set by the application itself or no diversion will occur. IP Diversion based on applying the modulus operation to a fingerprint of the IP address. RANDOM Diversion based on weighted random assignment. An incoming request is randomly routed to a version in the traffic split, with probability proportional to the version's traffic share. NetworkSettings
A NetworkSettings resource is a container for ingress settings for a version or service.
IngressTrafficAllowedIf unspecified, INGRESS_TRAFFIC_ALLOWED_ALL will be used.
EnumsINGRESS_TRAFFIC_ALLOWED_UNSPECIFIED Unspecified INGRESS_TRAFFIC_ALLOWED_ALL Allow HTTP traffic from public and private sources. INGRESS_TRAFFIC_ALLOWED_INTERNAL_ONLY Allow HTTP traffic from only private VPC sources. INGRESS_TRAFFIC_ALLOWED_INTERNAL_AND_LB Allow HTTP traffic from private VPC sources and through load balancers. Methods delete Deletes the specified service and all enclosed versions. get Gets the current configuration of the specified service. list Lists all the services in the application. patch Updates the configuration of the specified service.
