NAME
|
|
gcloud alpha compute instances tail-serial-port-output - periodically fetch
|
|
new output from a virtual machine instance's serial port and display it
|
|
as it becomes available
|
|
|
|
SYNOPSIS
|
|
gcloud alpha compute instances tail-serial-port-output INSTANCE_NAME
|
|
[--port=PORT] [--zone=ZONE] [GCLOUD_WIDE_FLAG ...]
|
|
|
|
DESCRIPTION
|
|
(ALPHA) gcloud alpha compute instances tail-serial-port-output is used to
|
|
tail the output from a Compute Engine virtual machine instance's serial
|
|
port. The serial port output from the instance will be printed to standard
|
|
output. This information can be useful for diagnostic purposes.
|
|
|
|
EXAMPLES
|
|
To fetch new output from instance's serial port and display it, run:
|
|
|
|
$ gcloud alpha compute instances tail-serial-port-output \
|
|
example-instance --zone=us-central1-b
|
|
|
|
POSITIONAL ARGUMENTS
|
|
INSTANCE_NAME
|
|
Name 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
|
|
|
|
FLAGS
|
|
--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.
|
|
|
|
--zone=ZONE
|
|
Zone of the instance to operate on. If not specified, you might be
|
|
prompted to select a zone (interactive mode only). gcloud attempts to
|
|
identify the appropriate zone by searching for resources in your
|
|
currently active project. If the zone cannot be determined, gcloud
|
|
prompts you for a selection with all available 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.
|
|
|
|
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:
|
|
|
|
$ gcloud compute instances tail-serial-port-output
|
|
|
|
$ gcloud beta compute instances tail-serial-port-output
