NAME

Name of the SSL health check to create.

--check-interval=CHECK_INTERVAL; default="5s"

How often to perform a health check for an instance. For example, specifying10s will run the check every 10 seconds.The default value is5s. See $gcloud topic datetimes forinformation on duration formats.

--description=DESCRIPTION

An optional string description for the SSL health check.

--enable-logging

Enable logging of health check probe results to Stackdriver. Logging is disabledby default.

Use --no-enable-logging to disable logging.

--healthy-threshold=HEALTHY_THRESHOLD; default=2

The number of consecutive successful health checks before an unhealthy instanceis marked as healthy. The default is 2.

--proxy-header=PROXY_HEADER; default="NONE"

The type of proxy protocol header to be sent to the backend.PROXY_HEADER must be one of:

NONE

No proxy header is added.

PROXY_V1

Adds the header "PROXY UNKNOWN\r\n".

--request=REQUEST

An optional string of up to 1024 characters to send once the health check TCPconnection has been established. The health checker then looks for a reply ofthe string provided in the--response field.

If--response is not configured, the health checker does not waitfor a response and regards the probe as successful if the TCP or SSL handshakewas successful.

--response=RESPONSE

An optional string of up to 1024 characters that the health checker expects toreceive from the instance. If the response is not received exactly, the healthcheck probe fails. If--response is configured, but not--request, the health checker will wait for a response anyway.Unless your system automatically sends out a message in response to a successfulhandshake, only configure--response to match an explicit--request.

--timeout=TIMEOUT; default="5s"

If Google Compute Engine doesn't receive a healthy response from the instance bythe time specified by the value of this flag, the health check request isconsidered a failure. For example, specifying10s will cause the check to wait for 10seconds before considering the request a failure. The default value is5s. See $gcloud topic datetimes forinformation on duration formats.

--unhealthy-threshold=UNHEALTHY_THRESHOLD; default=2

The number of consecutive health check failures before a healthy instance ismarked as unhealthy. The default is 2.

At most one of these can be specified:

--global

If set, the SSL health check is global.

--region=REGION

Region of the SSL health check to create. If not specified, you might beprompted to select a region (interactive mode only).

To avoid prompting when this flag is omitted, you can set thecompute/region property:

gcloudconfigsetcompute/regionREGION

A list of regions can be fetched by running:

gcloudcomputeregionslist

To unset the property, run:

gcloudconfigunsetcompute/region

Alternatively, the region can be stored in the environment variableCLOUDSDK_COMPUTE_REGION.

These flags configure the port that the health check monitors. If none isspecified, the default port of 80 is used. If both--port and--port-name are specified,--port takes precedence.

--port=PORT; default=80

The TCP port number that this health check monitors.

--port-name=PORT_NAME

The port name that this health check monitors. By default, this is empty.

--use-serving-port

If given, use the "serving port" for health checks:

• When health checking network endpoints in a Network Endpoint Group, use the portspecified with each endpoint.--use-serving-port must be used whenusing a Network Endpoint Group as a backend as this flag specifies theportSpecification option for a Health Check object.
• When health checking other backends, use the port or named port of the backendservice.
