- DESCRIPTION
- Send SSH commands to a Cloud TPU Queued Resource.
- EXAMPLES
-
To run an SSH command in a Cloud TPU Queued Resource's first node and first
worker (for example, to print the time since last boot), run:
gcloud compute tpus queued-resources ssh my-qr --command="last boot"To run the same command in all nodes and workers in a Cloud TPU Queued Resource (with the default batch size), run:
gcloud compute tpus queued-resources ssh my-qr --command="last boot" --worker=all --node=allTo run the same command in all nodes and workers in a Cloud TPU Queued Resource but batching the request in groups of 4, run:
gcloud compute tpus queued-resources ssh my-qr --command="last boot" --worker=all --node=all --batch-size=4 - POSITIONAL ARGUMENTS
-
- [
USER@]QR -
Specifies the Cloud TPU Queued Resource to send SSH command to.
USERQR - [--
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 queued-resources ssh example-instance --zone=us-central1-a -- -vvv -L 80:%TPU%:80

- FLAGS
-
--batch-size=BATCH_SIZE; default=64-
Batch size for simultaneous command execution on the client's side. When using a
comma-separated list (e.g. '1,4,6') or a range (e.g. '1-3') or ``all`` keyword
in
--workerflag, it executes the command concurrently in groups of the batch size. This flag takes a value greater than 0 to specify the batch size to control the concurrent connections that can be established with the TPU workers, or the special keyword ``all`` to allow the concurrent command executions on all the specified workers in--workerflag. Maximum value of this flag should not be more than the number of specified workers, otherwise the value will be treated as ``--batch-size=all``. --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.
--node=NODE; default="0"-
TPU node(s) to connect to. The supported value is a single 0-based index of the
node(s) in the case of a TPU Pod. When also using the
--commandflag, 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 node(s).Note that when targeting multiple nodes, you should run 'ssh-add' with your private key prior to executing the gcloud command. Default: 'ssh-add ~/.ssh/google_compute_engine'.
--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 queued-resources ssh example-instance --zone=us-central1-a --ssh-flag="-vvv" --ssh-flag="-L 80:localhost:80"This flag will replace occurences of
%USER%%TPU%80:162.222.181.197:80ssh(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_CHECKINGmust 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
--commandflag, 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
compute/zoneTo avoid prompting when this flag is omitted, you can set the
compute/zonegcloud config set compute/zone ZONEA list of zones can be fetched by running:
gcloud compute zones listTo unset the property, run:
gcloud config unset compute/zoneAlternatively, 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 Queued Resource's nodes and then exits.
Note: in the case of a TPU Pod, it will only run the command in the workers specified with the
--workerflag (defaults to worker all if not set).This flag argument must be specified if any of the other arguments in this group are specified.
--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:
--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.
--tunnel-through-iap-
Tunnel the SSH connection through Cloud Identity-Aware Proxy for TCP forwarding.
This flag must be specified to attempt to connect via IAP tunneling. If it is not set, and connection to a Cloud TPU VM without external IP address is attempted from outside the network, then the command will fail.
To use IAP tunneling, there must be firewall access to the SSH port for the IAP TCP IP address range for the network the TPU is created in. See the user guide for more details.
To learn more, see the IAP for TCP forwarding documentation.
-
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.
