gcloud compute instances tail-serial-port-output <INSTANCE_NAME>

Periodically fetch new output from a virtual machine instance's serial port and display it as it becomes available

Arguments

NameDescription
INSTANCE_NAMEName of the instance to operate on. For details on valid instance names, refer to the criteria documented under the field 'name' at: https://cloud.google.com/compute/docs/reference/rest/v1/instances

Options

NameDescription
--account <ACCOUNT>Google Cloud Platform user account to use for invocation. Overrides the default *core/account* property value for this command invocation
--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`
--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
--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
--helpDisplay detailed help
--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
--port <PORT>Instances can support up to four serial port outputs, numbered 1 through 4. By default, this command will return the output of the first serial port. Setting this flag will return the output of the requested serial port
--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
--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
--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*
--zone <ZONE>Zone of the instance to operate on. If not specified, the user may be prompted to select a zone. `gcloud` will attempt to identify the zone by searching for resources in the user's project. If the zone cannot be determined, the user will then be prompted with all Google Cloud Platform zones. + To avoid prompting when this flag is omitted, the user can set the ``compute/zone'' property: + $ gcloud config set compute/zone ZONE + A list of zones can be fetched by running: + $ gcloud compute zones list + To unset the property, run: + $ gcloud config unset compute/zone + Alternatively, the zone can be stored in the environment variable ``CLOUDSDK_COMPUTE_ZONE''
