NAME
gcloud compute health-checks create http - create a HTTP health check to monitor load balanced instances
SYNOPSIS
gcloud compute health-checks create http NAME [--check-interval=CHECK_INTERVAL; default="5s"] [--description=DESCRIPTION] [--enable-logging] [--healthy-threshold=HEALTHY_THRESHOLD; default=2] [--host=HOST] [--proxy-header=PROXY_HEADER; default="NONE"] [--request-path=REQUEST_PATH; default="/"] [--response=RESPONSE] [--source-regions=REGION,…,[…]] [--timeout=TIMEOUT; default="5s"] [--unhealthy-threshold=UNHEALTHY_THRESHOLD; default=2] [--global     | --region=REGION] [--port=PORT; default=80 --port-name=PORT_NAME --use-serving-port] [GCLOUD_WIDE_FLAG …]
DESCRIPTION
gcloud compute health-checks create http is used to create a non-legacy health check using the HTTP protocol. You can use this health check for Google Cloud load balancers or for managed instance group autohealing. For more information, see the health checks overview at: https://cloud.google.com/load-balancing/docs/health-check-concepts
POSITIONAL ARGUMENTS
NAME
Name of the HTTP health check to create.
FLAGS
--check-interval=CHECK_INTERVAL; default="5s"
How often to perform a health check for an instance. For example, specifying 10s will run the check every 10 seconds. The default value is 5s. See $ gcloud topic datetimes for information on duration formats.
--description=DESCRIPTION
An optional string description for the HTTP health check.
--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; default=2
The number of consecutive successful health checks before an unhealthy instance is marked as healthy. The default is 2.
--host=HOST
The value of the host header used for the health check. If unspecified, Google Cloud sets the host header to the IP address of the load balancer's forwarding rule.
--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-path=REQUEST_PATH; default="/"
The request path that this health check monitors. For example, /healthcheck. The default value is ``/´´.
--response=RESPONSE
When empty, status code of the response determines health. When not empty, presence of specified string in first 1024 characters of response body determines health. Only ASCII characters allowed.
--source-regions=REGION,…,[…]
Define the list of Google Cloud regions from which health checks are performed. This option is supported only for global health checks that will be referenced by DNS routing policies. If specified, the --check-interval field should be at least 30 seconds. The --proxy-header and --request fields (for TCP health checks) are not supported with this option.

If --source-regions is specified for a health check, then that health check cannot be used by a backend service or by a managed instance group (for autohealing).

--timeout=TIMEOUT; default="5s"
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. The default value is 5s. See $ gcloud topic datetimes for information on duration formats.
--unhealthy-threshold=UNHEALTHY_THRESHOLD; default=2
The number of consecutive health check failures before a healthy instance is marked as unhealthy. The default is 2.
At most one of these can be specified:
--global
If set, the HTTP health check is global.
--region=REGION
Region of the HTTP health check to create. 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 none is specified, 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 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.
