NAME
gcloud alpha compute health-checks update ssl - update a SSL health check
SYNOPSIS
gcloud alpha compute health-checks update ssl NAME [--check-interval=CHECK_INTERVAL] [--description=DESCRIPTION] [--enable-logging] [--healthy-threshold=HEALTHY_THRESHOLD] [--proxy-header=PROXY_HEADER] [--request=REQUEST] [--response=RESPONSE] [--timeout=TIMEOUT] [--unhealthy-threshold=UNHEALTHY_THRESHOLD] [--global     | --region=REGION] [--port=PORT --port-name=PORT_NAME --use-serving-port] [GCLOUD_WIDE_FLAG …]
DESCRIPTION
(ALPHA) gcloud alpha compute health-checks update ssl is used to update an existing SSL health check. Only arguments passed in will be updated on the health check. Other attributes will remain unaffected.
POSITIONAL ARGUMENTS
NAME
Name of the SSL health check to update.
FLAGS
--check-interval=CHECK_INTERVAL
How often to perform a health check for an instance. For example, specifying 10s will run the check every 10 seconds. See $ gcloud topic datetimes for information on duration formats.
--description=DESCRIPTION
A textual description for the SSL health check. Pass in an empty string to unset.
--enable-logging
Enable logging of health check probe results to Stackdriver. Logging is disabled by default.

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

--healthy-threshold=HEALTHY_THRESHOLD
The number of consecutive successful health checks before an unhealthy instance is marked as healthy.
--proxy-header=PROXY_HEADER
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 TCP connection has been established. The health checker then looks for a reply of the string provided in the --response field.

If --response is not configured, the health checker does not wait for a response and regards the probe as successful if the TCP or SSL handshake was successful.

Setting this to an empty string will clear any existing request value.

--response=RESPONSE
An optional string of up to 1024 characters that the health checker expects to receive from the instance. If the response is not received exactly, the health check 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 successful handshake, only configure --response to match an explicit --request. Setting this to an empty string will clear any existing response value.
--timeout=TIMEOUT
If Google Compute Engine doesn't receive a healthy response from the instance by the time specified by the value of this flag, the health check request is considered a failure. For example, specifying 10s will cause the check to wait for 10 seconds before considering the request a failure. See $ gcloud topic datetimes for information on duration formats.
--unhealthy-threshold=UNHEALTHY_THRESHOLD
The number of consecutive health check failures before a healthy instance is marked as unhealthy.
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 update. If not specified, you might be prompted to select a region (interactive mode only).

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

gcloud config set compute/region REGION

A list of regions can be fetched by running: 

gcloud compute regions list

To unset the property, run: 

gcloud config unset compute/region

Alternatively, the region can be stored in the environment variable CLOUDSDK_COMPUTE_REGION.

These flags configure the port that the health check monitors. If both --port and --port-name are specified, --port takes precedence.
--port=PORT
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. Setting this to an empty string will clear any existing port-name value.
--use-serving-port
If given, use the "serving port" for health checks:
  • When health checking network endpoints in a Network Endpoint Group, use the port specified with each endpoint. --use-serving-port must be used when using a Network Endpoint Group as a backend as this flag specifies the portSpecification option for a Health Check object.
  • When health checking other backends, use the port or named port of the backend service.
GCLOUD WIDE FLAGS
These flags are available to all commands: --access-token-file, --account, --billing-project, --configuration, --flags-file, --flatten, --format, --help, --impersonate-service-account, --log-http, --project, --quiet, --trace-token, --user-output-enabled, --verbosity.

Run $ gcloud help for details.

NOTES
This command is currently in alpha and might change without notice. If this command fails with API permission errors despite specifying the correct project, you might be trying to access an API with an invitation-only early access allowlist. These variants are also available:
