- DESCRIPTION
- gcloud compute instances get-serial-port-output is used to get the output from a Compute Engine virtual machine's serial port. The serial port output from the virtual machine will be printed to standard output. This information can be useful for diagnostic purposes.
- EXAMPLES
-
To get the output from instance's serial port, run:
gcloud compute instances get-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.
--start
=START
- Specifies the byte index (zero-based) of the first byte you want returned. Use this flag if you want to continue getting the output from a previous request that was too long to return in one attempt. The last byte returned in a request will be reported on STDERR.
--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
property:compute/zone
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
