Synopsis ¶

Creates a BackendService resource in the specified project using the data included in the request.

Requirements ¶

The below requirements are needed on the host that executes this module.

python >= 2.6
requests >= 2.18.4
google-auth >= 1.3.0

Parameters ¶

Parameter			Choices/Defaults	Comments
affinity_cookie_ttl_sec				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.
auth_kind required			Choices: machineaccount serviceaccount application	The type of credential used.
backends				The list of backends that serve this BackendService.
	group			A reference to InstanceGroup resource.
	description			An optional description of this resource. Provide this property when you create the resource.
	max_rate			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 maxRatePerInstance must be set. This cannot be used for internal load balancing.
	max_connections_per_instance			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. This cannot be used for internal load balancing.
	max_utilization			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]. This cannot be used for internal load balancing.
	max_rate_per_instance			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. This cannot be used for internal load balancing.
	balancing_mode		Choices: UTILIZATION RATE CONNECTION	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). This cannot be used for internal load balancing.
	capacity_scaler			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]. This cannot be used for internal load balancing.
	max_connections			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 maxConnectionsPerInstance must be set. This cannot be used for internal load balancing.
cdn_policy				Cloud CDN configuration for this BackendService.
	cache_key_policy			The CacheKeyPolicy for this CdnPolicy.
		include_protocol	Choices: no yes	If true, http and https requests will be cached separately.
		query_string_whitelist		Names of query string parameters to include in cache keys. All other parameters will be excluded. Either specify query_string_whitelist or query_string_blacklist, not both. '&' and '=' will be percent encoded and not treated as delimiters.
		include_host	Choices: no yes	If true requests to different hosts will be cached separately.
		query_string_blacklist		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.
		include_query_string	Choices: no yes	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.
connection_draining				Settings for connection draining.
	draining_timeout_sec			Time for which instance will be drained (not accept new connections, but still work to finish started).
description				An optional description of this resource.
enable_cdn			Choices: no yes	If true, enable Cloud CDN for this BackendService. When the load balancing scheme is INTERNAL, this field is not used.
health_checks				The list of URLs to the HttpHealthCheck or HttpsHealthCheck resource for health checking this BackendService. Currently at most one health check can be specified, and a health check is required. For internal load balancing, a URL to a HealthCheck resource must be specified instead.
name				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.
port_name				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. When the load balancing scheme is INTERNAL, this field is not used.
project				The Google Cloud Platform project to use.
protocol			Choices: HTTP HTTPS TCP SSL	The protocol this BackendService uses to communicate with backends. Possible values are HTTP, HTTPS, TCP, and SSL. The default is HTTP. For internal load balancing, the possible values are TCP and UDP, and the default is TCP.
region				A reference to Region resource.
scopes required				Array of scopes to be used.
service_account_email				An optional service account email address if machineaccount is selected and the user does not wish to use the default email.
service_account_file				The path of a Service Account JSON file if serviceaccount is selected as type.
session_affinity			Choices: NONE CLIENT_IP GENERATED_COOKIE CLIENT_IP_PROTO CLIENT_IP_PORT_PROTO	Type of session affinity to use. The default is NONE. When the load balancing scheme is EXTERNAL, can be NONE, CLIENT_IP, or GENERATED_COOKIE. When the load balancing scheme is INTERNAL, can be NONE, CLIENT_IP, CLIENT_IP_PROTO, or CLIENT_IP_PORT_PROTO. When the protocol is UDP, this field is not used.
state required			Choices: present ← absent	Whether the given object should exist in GCP
timeout_sec				How many seconds to wait for the backend before considering it a failed request. Default is 30 seconds. Valid range is [1, 86400]. aliases: timeout_seconds

Notes ¶

Note

For authentication, you can set service_account_file using the GCP_SERVICE_ACCOUNT_FILE env variable.
For authentication, you can set service_account_email using the GCP_SERVICE_ACCOUNT_EMAIL env variable.
For authentication, you can set auth_kind using the GCP_AUTH_KIND env variable.
For authentication, you can set scopes using the GCP_SCOPES env variable.
Environment variables values will only be used if the playbook values are not set.
The service_account_email and service_account_file options are mutually exclusive.
