Fields
id

string (fixed64 format)

[Output Only] The unique identifier for the resource. This identifier is defined by the server.

creationTimestamp

string

[Output Only] Creation timestamp in 3339 text format.

name

string

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.

description

string

An optional description of this resource. Provide this property when you create the resource.

checkIntervalSec

number

How often (in seconds) to send a health check. The default value is 5 seconds.

timeoutSec

number

How long (in seconds) to wait before claiming failure. The default value is 5 seconds. It is invalid for timeoutSec to have greater value than checkIntervalSec.

unhealthyThreshold

number

A so-far healthy instance will be marked unhealthy after this many consecutive failures. The default value is 2.

healthyThreshold

number

A so-far unhealthy instance will be marked healthy after this many consecutive successes. The default value is 2.

type

enum

Specifies the type of the healthCheck, either TCP, SSL, HTTP or HTTPS. If not specified, the default is TCP. Exactly one of the protocol-specific health check field must be specified, which must match type field.

tcpHealthCheck

object

tcpHealthCheck.port

number

The TCP port number for the health check request. The default value is 80. Valid values are 1 through 65535.

tcpHealthCheck.portName

string

Port name as defined in InstanceGroup#NamedPort#name. If both port and portName are defined, port takes precedence.

tcpHealthCheck.request

string

The application data to send once the TCP connection has been established (default value is empty). If both request and response are empty, the connection establishment alone will indicate health. The request data can only be ASCII.

tcpHealthCheck.response

string

The bytes to match against the beginning of the response data. If left empty (the default value), any response will indicate health. The response data can only be ASCII.

tcpHealthCheck.proxyHeader

enum

Specifies the type of proxy header to append before sending data to the backend, either NONE or PROXY_V1. The default is NONE.

sslHealthCheck

object

sslHealthCheck.port

number

The TCP port number for the health check request. The default value is 443. Valid values are 1 through 65535.

sslHealthCheck.portName

string

Port name as defined in InstanceGroup#NamedPort#name. If both port and portName are defined, port takes precedence.

sslHealthCheck.request

string

The application data to send once the SSL connection has been established (default value is empty). If both request and response are empty, the connection establishment alone will indicate health. The request data can only be ASCII.

sslHealthCheck.response

string

The bytes to match against the beginning of the response data. If left empty (the default value), any response will indicate health. The response data can only be ASCII.

sslHealthCheck.proxyHeader

enum

Specifies the type of proxy header to append before sending data to the backend, either NONE or PROXY_V1. The default is NONE.

httpHealthCheck

object

httpHealthCheck.port

number

The TCP port number for the health check request. The default value is 80. Valid values are 1 through 65535.

httpHealthCheck.portName

string

Port name as defined in InstanceGroup#NamedPort#name. If both port and portName are defined, port takes precedence.

httpHealthCheck.host

string

The value of the host header in the HTTP health check request. If left empty (default value), the IP on behalf of which this health check is performed will be used.

httpHealthCheck.requestPath

string

The request path of the HTTP health check request. The default value is /.

httpHealthCheck.proxyHeader

enum

Specifies the type of proxy header to append before sending data to the backend, either NONE or PROXY_V1. The default is NONE.

httpsHealthCheck

object

httpsHealthCheck.port

number

The TCP port number for the health check request. The default value is 443. Valid values are 1 through 65535.

httpsHealthCheck.portName

string

Port name as defined in InstanceGroup#NamedPort#name. If both port and portName are defined, port takes precedence.

httpsHealthCheck.host

string

The value of the host header in the HTTPS health check request. If left empty (default value), the IP on behalf of which this health check is performed will be used.

httpsHealthCheck.requestPath

string

The request path of the HTTPS health check request. The default value is /.

httpsHealthCheck.proxyHeader

enum

Specifies the type of proxy header to append before sending data to the backend, either NONE or PROXY_V1. The default is NONE.

kind

string

Type of the resource.
