The CIDR block that the TPU node will use when selecting an IP address.
This CIDR block must be a /29 block; the Compute Engine networks API
forbids a smaller block, and using a larger block would be wasteful (a
node can only consume one IP address). Errors will occur if the CIDR block
has already been used for a currently existing TPU node, the CIDR block
conflicts with any subnetworks in the user's provided network, or the
provided network is peered with another network that is using that CIDR
block.
The name of a network they wish to peer the TPU node to. It must be a
preexisting Compute Engine network inside of the project on which this API
has been activated. If none is provided, "default" will be used.
Output only. The network endpoints where TPU workers can be accessed and
sent work. It is recommended that Tensorflow clients of the node reach out
to the 0th entry in this map first.
Output only. The service account used to run the tensor flow services
within the node. To share resources, including Google Cloud Storage data,
with the Tensorflow job running in the Node, this account must have
permissions to that data.
Whether the VPC peering for the node is set up through Service Networking
API. The VPC Peering should be set up before provisioning the node.
If this field is set, cidr_block field should not be specified. If the
network, that you want to peer the TPU Node to, is Shared VPC networks,
the node must be created with this this field enabled.
