Arguments

NameDescription
BACKEND_SERVICE_NAMEName of the backend service to update

Options

NameDescription
--account <ACCOUNT>Google Cloud Platform user account to use for invocation. Overrides the default *core/account* property value for this command invocation
--affinity-cookie-ttl <AFFINITY_COOKIE_TTL>If session-affinity is set to "generated_cookie", this flag sets the TTL, in seconds, of the resulting cookie. A setting of 0 indicates that the cookie should be transient. See $ gcloud topic datetimes for information on duration formats
--billing-project <BILLING_PROJECT>The Google Cloud Platform project that will be charged quota for operations performed in gcloud. If you need to operate on one project, but need quota against a different project, you can use this flag to specify the billing project. If both `billing/quota_project` and `--billing-project` are specified, `--billing-project` takes precedence. Run `$ gcloud config set --help` to see more information about `billing/quota_project`
--cache-key-include-hostEnable including host in cache key. If enabled, requests to different hosts will be cached separately. Can only be applied for global resources
--cache-key-include-protocolEnable including protocol in cache key. If enabled, http and https requests will be cached separately. Can only be applied for global resources
--cache-key-include-query-stringEnable including query string in cache key. If enabled, the query string parameters will be included according to --cache-key-query-string-whitelist and --cache-key-query-string-blacklist. If disabled, the entire query string will be excluded. Use "--cache-key-query-string-blacklist=" (sets the blacklist to the empty list) to include the entire query string. Can only be applied for global resources
--cache-key-query-string-blacklist <QUERY_STRING>Specifies a comma separated list of query string parameters to exclude in cache keys. All other parameters will be included. Either specify --cache-key-query-string-whitelist or --cache-key-query-string-blacklist, not both. '&' and '=' will be percent encoded and not treated as delimiters. Can only be applied for global resources
--cache-key-query-string-whitelist <QUERY_STRING>Specifies a comma separated list of query string parameters to include in cache keys. All other parameters will be excluded. Either specify --cache-key-query-string-whitelist or --cache-key-query-string-blacklist, not both. '&' and '=' will be percent encoded and not treated as delimiters. Can only be applied for global resources
--configuration <CONFIGURATION>The configuration to use for this command invocation. For more information on how to use configurations, run: `gcloud topic configurations`. You can also use the CLOUDSDK_ACTIVE_CONFIG_NAME environment variable to set the equivalent of this flag for a terminal session
--connection-drain-on-failoverConnection drain is enabled by default and on failover or failback connections will be drained. If connection drain is disabled, the existing connection state will be cleared immediately on a best effort basis on failover or failback, all connections will then be served by the active pool of instances. Not compatible with the --global flag, load balancing scheme must be INTERNAL, and the protocol must be TCP
--connection-draining-timeout <CONNECTION_DRAINING_TIMEOUT>Connection draining timeout to be used during removal of VMs from instance groups. This guarantees that for the specified time all existing connections to a VM will remain untouched, but no new connections will be accepted. Set timeout to zero to disable connection draining. Enable feature by specifying a timeout of up to one hour. If the flag is omitted API default value (0s) will be used. See $ gcloud topic datetimes for information on duration formats
--custom-request-header <CUSTOM_REQUEST_HEADER>Specifies a HTTP Header to be added by your load balancer. This flag can be repeated to specify multiple headers. For example: + $ {command} NAME --custom-request-header "header-name: value" --custom-request-header "another-header:"
--description <DESCRIPTION>An optional, textual description for the backend service
--drop-traffic-if-unhealthyEnable dropping of traffic if there are no healthy VMs detected in both the primary and backup instance groups. Not compatible with the --global flag and load balancing scheme must be INTERNAL
--enable-cdnEnable or disable Cloud CDN for the backend service. Only available for backend services with --load-balancing-scheme=EXTERNAL that use a --protocol of HTTP, HTTPS, or HTTP2. Cloud CDN caches HTTP responses at the edge of Google's network. Cloud CDN is disabled by default. Use *--enable-cdn* to enable and *--no-enable-cdn* to disable
--enable-loggingThe logging options for the load balancer traffic served by this backend service. If logging is enabled, logs will be exported to Stackdriver. Enabled by default. Use *--enable-logging* to enable and *--no-enable-logging* to disable
--failover-ratio <FAILOVER_RATIO>If the ratio of the healthy VMs in the primary backend is at or below this number, traffic arriving at the load-balanced IP will be directed to the failover backend(s). Not compatible with the --global flag
--flags-file <YAML_FILE>A YAML or JSON file that specifies a *--flag*:*value* dictionary. Useful for specifying complex flag values with special characters that work with any command interpreter. Additionally, each *--flags-file* arg is replaced by its constituent flags. See $ gcloud topic flags-file for more information
--flatten <KEY>Flatten _name_[] output resource slices in _KEY_ into separate records for each item in each slice. Multiple keys and slices may be specified. This also flattens keys for *--format* and *--filter*. For example, *--flatten=abc.def* flattens *abc.def[].ghi* references to *abc.def.ghi*. A resource record containing *abc.def[]* with N elements will expand to N records in the flattened output. This flag interacts with other flags that are applied in this order: *--flatten*, *--sort-by*, *--filter*, *--limit*
--format <FORMAT>Set the format for printing command output resources. The default is a command-specific human-friendly output format. The supported formats are: `config`, `csv`, `default`, `diff`, `disable`, `flattened`, `get`, `json`, `list`, `multi`, `none`, `object`, `table`, `text`, `value`, `yaml`. For more details run $ gcloud topic formats
--globalIf set, the backend service is global
--global-health-checksIf set, the health checks are global
--health-checks <HEALTH_CHECK>Specifies a list of health check objects for checking the health of the backend service. Currently at most one health check can be specified. Health checks need not be for the same protocol as that of the backend service
--health-checks-region <HEALTH_CHECKS_REGION>Region of the health checks to operate on. If not specified, you may be prompted to select a region. + 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''
--helpDisplay detailed help
--http-health-checks <HTTP_HEALTH_CHECK>Specifies a list of legacy HTTP health check objects for checking the health of the backend service. + Legacy health checks are not recommended for backend services. It is possible to use a legacy health check on a backend service for a HTTP(S) load balancer if that backend service uses instance groups. For more information, refer to this guide: https://cloud.google.com/load-balancing/docs/health-check-concepts#lb_guide
--https-health-checks <HTTPS_HEALTH_CHECK>Specifies a list of legacy HTTPS health check objects for checking the health of the backend service. + Legacy health checks are not recommended for backend services. It is possible to use a legacy health check on a backend service for a HTTP(S) load balancer if that backend service uses instance groups. For more information, refer to this guide: https://cloud.google.com/load-balancing/docs/health-check-concepts#lb_guide
--iap <disabled|enabled,[oauth2-client-id=OAUTH2-CLIENT-ID,oauth2-client-secret=OAUTH2-CLIENT-SECRET]>Change the Identity Aware Proxy (IAP) service configuration for the backend service. You can set IAP to 'enabled' or 'disabled', or modify the OAuth2 client configuration (oauth2-client-id and oauth2-client-secret) used by IAP. If any fields are unspecified, their values will not be modified. For instance, if IAP is enabled, '--iap=disabled' will disable IAP, and a subsequent '--iap=enabled' will then enable it with the same OAuth2 client configuration as the first time it was enabled. See https://cloud.google.com/iap/ for more information about this feature
--impersonate-service-account <SERVICE_ACCOUNT_EMAIL>For this gcloud invocation, all API requests will be made as the given service account instead of the currently selected account. This is done without needing to create, download, and activate a key for the account. In order to perform operations as the service account, your currently selected account must have an IAM role that includes the iam.serviceAccounts.getAccessToken permission for the service account. The roles/iam.serviceAccountTokenCreator role has this permission or you may create a custom role. Overrides the default *auth/impersonate_service_account* property value for this command invocation
--log-httpLog all HTTP server requests and responses to stderr. Overrides the default *core/log_http* property value for this command invocation
--logging-sample-rate <LOGGING_SAMPLE_RATE>This field can only be specified if logging is enabled for the backend service. The value of the field must be a float in the range [0, 1]. This configures the sampling rate of requests to the load balancer where 1.0 means all logged requests are reported and 0.0 means no logged requests are reported. The default value is 1.0
--no-custom-request-headersRemove all custom request headers for the backend service
--no-health-checksRemoves all health checks for the backend service
--port-name <PORT_NAME>The name of a service that has been added to an instance group in this backend. Instance group services map a name to a port number which is used by the load balancing service. Only one ``port-name'' may be added to a backend service, and that name must exist as a service on all instance groups that are a part of this backend service. The port number associated with the name may differ between instances. If you do not specify this flag, your instance groups must have a service named ``http'' configured. See also `gcloud compute instance-groups set-named-ports --help`. The ``port-name'' parameter cannot be set if the load-balancing-scheme is INTERNAL
--project <PROJECT_ID>The Google Cloud Platform project ID to use for this invocation. If omitted, then the current project is assumed; the current project can be listed using `gcloud config list --format='text(core.project)'` and can be set using `gcloud config set project PROJECTID`. + `--project` and its fallback `core/project` property play two roles in the invocation. It specifies the project of the resource to operate on. It also specifies the project for API enablement check, quota, and billing. To specify a different project for quota and billing, use `--billing-project` or `billing/quota_project` property
--protocol <PROTOCOL>Protocol for incoming requests. + If the `load-balancing-scheme` is `INTERNAL` (internal TCP/UDP load balancers), the protocol must be one of: TCP, UDP. + If the `load-balancing-scheme` is `INTERNAL_SELF_MANAGED` (Traffic Director), the protocol must be one of: HTTP, HTTPS, HTTP2, GRPC. + If the `load-balancing-scheme` is `INTERNAL_MANAGED` (internal HTTP(S) load balancers), the protocol must be one of: HTTP, HTTPS, HTTP2. + If the `load-balancing-scheme` is `EXTERNAL` (HTTP(S), SSL proxy, or TCP proxy load balancers), the protocol must be one of: HTTP, HTTPS, HTTP2, SSL, TCP
--quietDisable all interactive prompts when running gcloud commands. If input is required, defaults will be used, or an error will be raised. Overrides the default core/disable_prompts property value for this command invocation. This is equivalent to setting the environment variable `CLOUDSDK_CORE_DISABLE_PROMPTS` to 1
--region <REGION>Region of the backend service to update. Overrides the default *compute/region* property value for this command invocation
--security-policy <SECURITY_POLICY>The security policy that will be set for this backend service
--session-affinity <SESSION_AFFINITY>The type of session affinity to use. Supports both TCP and UDP. _SESSION_AFFINITY_ must be one of: + *CLIENT_IP*::: Route requests to instances based on the hash of the client's IP address. *CLIENT_IP_PORT_PROTO*::: (Applicable if `--load-balancing-scheme` is `INTERNAL`) Connections from the same client IP with the same IP protocol and port will go to the same backend VM while that VM remains healthy. *CLIENT_IP_PROTO*::: (Applicable if `--load-balancing-scheme` is `INTERNAL`) Connections from the same client IP with the same IP protocol will go to the same backend VM while that VM remains healthy. *GENERATED_COOKIE*::: (Applicable if `--load-balancing-scheme` is `INTERNAL_MANAGED`, `INTERNAL_SELF_MANAGED`, or `EXTERNAL`) If the `--load-balancing-scheme` is `EXTERNAL`, routes requests to backend VMs or endpoints in a NEG, based on the contents of the `GCLB` cookie set by the load balancer. Only applicable when `--protocol` is HTTP, HTTPS, or HTTP2. If the `--load-balancing-scheme` is `INTERNAL_MANAGED` or `INTERNAL_SELF_MANAGED`, routes requests to backend VMs or endpoints in a NEG, based on the contents of the `GCILB` cookie set by the proxy. (If no cookie is present, the proxy chooses a backend VM or endpoint and sends a `Set-Cookie` response for future requests.) If the `--load-balancing-scheme` is `INTERNAL_SELF_MANAGED`, routes requests to backend VMs or endpoints in a NEG, based on the contents of a cookie set by Traffic Director. *HEADER_FIELD*::: (Applicable if `--load-balancing-scheme` is `INTERNAL_MANAGED` or `INTERNAL_SELF_MANAGED`) Route requests to backend VMs or endpoints in a NEG based on the value of the HTTP header named in the `--custom-request-header` flag. This session affinity is only valid if the load balancing locality policy is either RING_HASH or MAGLEV and the backend service's consistent hash specifies the name of the HTTP header. *HTTP_COOKIE*::: (Applicable if `--load-balancing-scheme` is `INTERNAL_MANAGED` or `INTERNAL_SELF_MANAGED`) Route requests to backend VMs or endpoints in a NEG, based on an HTTP cookie named in the `HTTP_COOKIE` flag (with the optional `--affinity-cookie-ttl` flag). If the client has not provided the cookie, the proxy generates the cookie and returns it to the client in a `Set-Cookie` header. This session affinity is only valid if the load balancing locality policy is either `RING_HASH` or `MAGLEV` and the backend service's consistent hash specifies the HTTP cookie. *NONE*::: Session affinity is disabled. ::: +
--signed-url-cache-max-age <SIGNED_URL_CACHE_MAX_AGE>The amount of time up to which the response to a signed URL request will be cached in the CDN. After this time period, the Signed URL will be revalidated before being served. Cloud CDN will internally act as though all responses from this backend had a `Cache-Control: public, max-age=[TTL]` header, regardless of any existing Cache-Control header. The actual headers served in responses will not be altered. + For example, specifying `12h` will cause the responses to signed URL requests to be cached in the CDN up to 12 hours. See $ gcloud topic datetimes for information on duration formats. + This flag only affects signed URL requests
--timeout <TIMEOUT>Applicable to all load balancers except internal TCP/UDP load balancers. For internal TCP/UDP load balancers (``load-balancing-scheme'' INTERNAL), ``timeout'' is ignored. + If the ``protocol'' is HTTP, HTTPS, or HTTP2, ``timeout'' is a request/response timeout for HTTP(S) traffic, meaning the amount of time that the load balancer waits for a backend to return a full response to a request. If WebSockets traffic is supported, the ``timeout'' parameter sets the maximum amount of time that a WebSocket can be open (idle or not). + For example, for HTTP, HTTPS, or HTTP2 traffic, specifying a ``timeout'' of 10s means that backends have 10 seconds to respond to the load balancer's requests. The load balancer retries the HTTP GET request one time if the backend closes the connection or times out before sending response headers to the load balancer. If the backend sends response headers or if the request sent to the backend is not an HTTP GET request, the load balancer does not retry. If the backend does not reply at all, the load balancer returns a 502 Bad Gateway error to the client. + If the ``protocol'' is SSL or TCP, ``timeout'' is an idle timeout
--trace-token <TRACE_TOKEN>Token used to route traces of service requests for investigation of issues. Overrides the default *core/trace_token* property value for this command invocation
--user-output-enabledPrint user intended output to the console. Overrides the default *core/user_output_enabled* property value for this command invocation. Use *--no-user-output-enabled* to disable
--verbosity <VERBOSITY>Override the default verbosity for this command. Overrides the default *core/verbosity* property value for this command invocation. _VERBOSITY_ must be one of: *debug*, *info*, *warning*, *error*, *critical*, *none*
