- DESCRIPTION
- SSH into a Cloud TPU VM.
- EXAMPLES
-
To SSH into a Cloud TPU VM, run:
gcloud compute tpus tpu-vm ssh my-tpu
To SSH into worker 1 on a Cloud TPU VM Pod, run:
gcloud compute tpus tpu-vm ssh my-tpu --worker=1
To run an SSH command in a Cloud TPU VM (for example, to print the time since last boot), run:
gcloud compute tpus tpu-vm ssh my-tpu --command="last boot"
To run the same command in all workers in a Cloud TPU VM simultaneously, run:
gcloud compute tpus tpu-vm ssh my-tpu --command="last boot" --worker=all
- POSITIONAL ARGUMENTS
-
- [
USER
@]TPU
-
Specifies the Cloud TPU VM to SSH into.
specifies the username with which to SSH. If omitted, the user login name is used.USER
specifies the name of the Cloud TPU VM to SSH into.TPU
- [--
SSH_ARGS
…] -
Flags and positionals passed to the underlying ssh implementation.
The '--' argument must be specified between gcloud specific args on the left and
SSH_ARGS on the right. Example:
gcloud compute tpus tpu-vm ssh example-instance --zone=us-central1-a -- -vvv -L 80:%TPU%:80
- [
- FLAGS
-
--dry-run
- Print the equivalent scp/ssh command that would be run to stdout, instead of executing it.
--force-key-file-overwrite
-
If enabled, the gcloud command-line tool will regenerate and overwrite the files
associated with a broken SSH key without asking for confirmation in both
interactive and non-interactive environments.
If disabled, the files associated with a broken SSH key will not be regenerated and will fail in both interactive and non-interactive environments.
--internal-ip
- Connect to TPU VMs using their internal IP addresses rather than their external IP addresses. Use this to connect from a Google Compute Engine VM to a TPU VM on the same VPC network, or between two peered VPC networks.
--plain
-
Suppress the automatic addition of
ssh(1)
/scp(1)
flags. This flag is useful if you want to take care of authentication yourself or use specific ssh/scp features. --ssh-flag
=SSH_FLAG
-
Additional flags to be passed to
ssh(1)
. It is recommended that flags be passed using an assignment operator and quotes. Example:gcloud compute tpus tpu-vm ssh example-instance --zone=us-central1-a --ssh-flag="-vvv" --ssh-flag="-L 80:localhost:80"
This flag will replace occurences of
and%USER%
with their dereferenced values. For example, passing ``80:%TPU%:80`` into the flag is equivalent to passing%TPU%
to80:162.222.181.197:80
ssh(1)
if the external IP address of 'example-instance' is 162.222.181.197.If connecting to the instance's external IP, then %TPU% is replaced with that, otherwise it is replaced with the internal IP.
--ssh-key-file
=SSH_KEY_FILE
-
The path to the SSH key file. By default, this is
.~/.ssh/google_compute_engine
--strict-host-key-checking
=STRICT_HOST_KEY_CHECKING
-
Override the default behavior of StrictHostKeyChecking for the connection. By
default, StrictHostKeyChecking is set to 'no' the first time you connect to an
instance, and will be set to 'yes' for all subsequent connections.
STRICT_HOST_KEY_CHECKING
must be one of:yes
,no
,ask
. --worker
=WORKER
; default="0"-
TPU worker to connect to. The supported value is a single 0-based index of the
worker in the case of a TPU Pod. When also using the
--command
flag, it additionally supports a comma-separated list (e.g. '1,4,6'), range (e.g. '1-3'), or special keyword ``all" to run the command concurrently on each of the specified workers.Note that when targeting multiple workers, you should run 'ssh-add' with your private key prior to executing the gcloud command. Default: 'ssh-add ~/.ssh/google_compute_engine'.
--zone
=ZONE
-
Zone of the tpu to ssh. If not specified and the
property isn't set, you might be prompted to select a zone (interactive mode only).compute/zone
To avoid prompting when this flag is omitted, you 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
-
These arguments are used to run commands using SSH.
--command
=COMMAND
-
Command to run on the Cloud TPU VM.
Runs the command on the target Cloud TPU VM and then exits.
Note: in the case of a TPU Pod, it will only run the command in the workers specified with the
--worker
flag (defaults to worker 0 if not set). --output-directory
=OUTPUT_DIRECTORY
-
Path to the directory to output the logs of the commands.
The path can be relative or absolute. The directory must already exist.
If not specified, standard output will be used.
The logs will be written in files named {WORKER_ID}.log. For example: "2.log".
-
At most one of these can be specified:
--ssh-key-expiration
=SSH_KEY_EXPIRATION
- The time when the ssh key will be valid until, such as "2017-08-29T18:52:51.142Z." This is only valid if the instance is not using OS Login. See $ gcloud topic datetimes for information on time formats.
--ssh-key-expire-after
=SSH_KEY_EXPIRE_AFTER
- The maximum length of time an SSH key is valid for once created and installed, e.g. 2m for 2 minutes. See $ gcloud topic datetimes for information on duration formats.
