gcloud compute health-checks update http2 - update a HTTP2 health check
gcloud compute health-checks update http2 NAME [--check-interval=CHECK_INTERVAL] [--description=DESCRIPTION] [--enable-logging] [--healthy-threshold=HEALTHY_THRESHOLD] [--host=HOST] [--proxy-header=PROXY_HEADER] [--request-path=REQUEST_PATH] [--response=RESPONSE] [--timeout=TIMEOUT] [--unhealthy-threshold=UNHEALTHY_THRESHOLD] [--global | --region=REGION] [--port=PORT --port-name=PORT_NAME --use-serving-port] [GCLOUD_WIDE_FLAG ...]
gcloud compute health-checks update http2 is used to update an existing HTTP2 health check. Only arguments passed in will be updated on the health check. Other attributes will remain unaffected.
To update health check interval to 10s, run:
$ gcloud compute health-checks update http2 my-health-check-name \ --check-interval=10s
- NAME
Name of the HTTP2 health check to update.
- --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 HTTP2 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.
- --host=HOST
The value of the host header used in this HTTP health check request. The host header is empty by default. When empty, the health check will set the host header to the IP address of the backend VM or endpoint. You can set the host header to an empty value to return to this default behavior.
- --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-path=REQUEST_PATH
The request path that this health check monitors. For example, /healthcheck.
- --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.
- --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 HTTP2 health check is global.
- --region=REGION
Region of the HTTP2 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.
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.
