If left empty (default value), the public IP on behalf of which this health check is performed will be used.

The request path of the HTTP health check request.
The default value is /.
https_health_check
A nested object resource.
port_name
Port name as defined in InstanceGroup#NamedPort#name. If both port and port_name are defined, port takes precedence.

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.
project Default:
None

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

timeout_sec Default:
5
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.

aliases: timeout_seconds
type
    Choices:
  • TCP
  • SSL
  • HTTP
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.
unhealthy_threshold Default:
2
A so-far healthy instance will be marked unhealthy after this many consecutive failures. The default value is 2.

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.
