SYNOPSIS: gcloud alpha compute tpus tpu-vm scp [[USER@]INSTANCE:]SRC [[[USER@]INSTANCE:]SRC …] [[USER@]INSTANCE:]DEST [--batch-size=BATCH_SIZE; default="all"] [--compress] [--dry-run] [--force-key-file-overwrite] [--plain] [--recurse] [--scp-flag=SCP_FLAG] [--ssh-key-file=SSH_KEY_FILE] [--strict-host-key-checking=STRICT_HOST_KEY_CHECKING] [--worker=WORKER; default="0"] [--zone=ZONE] [--internal-ip | --tunnel-through-iap] [--ssh-key-expiration=SSH_KEY_EXPIRATION | --ssh-key-expire-after=SSH_KEY_EXPIRE_AFTER] [GCLOUD_WIDE_FLAG …]
DESCRIPTION: (ALPHA) Copy files to and from a Cloud TPU VM via SCP (Alpha).
EXAMPLES: To copy a file (for example, a text file in the local home directory) to a Cloud TPU VM, run:
gcloud alpha compute tpus tpu-vm scp ~/my-file my-tpu:

To copy a file into all workers in a Cloud TPU VM, run:
gcloud alpha compute tpus tpu-vm scp ~/my-file my-tpu: --worker=all

To copy a file from a Cloud TPU VM to the home directory of the local computer, run:
gcloud alpha compute tpus tpu-vm scp my-tpu:~/my-file ~/

To copy all files in a folder to a Cloud TPU VM, run:
gcloud alpha compute tpus tpu-vm scp ~/my-folder/ my-tpu: --recurse
POSITIONAL ARGUMENTS: [[USER@]INSTANCE:]SRC [[[USER@]INSTANCE:]SRC …]

Specifies the files to copy.

[[USER@]INSTANCE:]DEST

Specifies a destination for the source files.
FLAGS: --batch-size=BATCH_SIZE; default="all"

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 --worker flag, 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 --worker flag. 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``.

--compress

Enable compression.

--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.

--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.

--recurse

Upload directories recursively.

--scp-flag=SCP_FLAG

Additional flags to be passed to scp(1). This flag may be repeated.

--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 scp. If not specified and the compute/zone property isn't set, you might be prompted to select a zone (interactive mode only).
To avoid prompting when this flag is omitted, you 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.

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.
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. This variant is also available:
