NEO testnet-preview4 storage node configuration

There is a prepared configuration for NeoFS storage node deployment in NEO testnet-preview4. The Easiest way to deploy storage node is to use prepared docker image of storage node and run it with docker-compose.

Build image

To build custom neofs-storage node image for NEO testnet-preview4:

neofs-node$ make image-storage-testnet
...

Deploy node

To run storage node in NEO testnet-preview4 environment you should deposit GAS assets, update docker-compose file and run it.

Deposit

Storage node holder should deposit assets because it generates a bit of sidechain GAS for node's wallet. Sidechain GAS used to send bootstrap tx.

To make a deposit invoke deposit method of NeoFS contract in testnet-preview4. There are three arguments in this method:

• scripthash of the wallet
• amount of GAS (in decimal)
• scripthash of the storage node wallet.

NeoFS contract scripthash in NEO testnet-preview4 is 121da848e5239d24353c7b567a719d27e0fe7c06

Last argument can be empty if you want to use wallet key as storage node key. See a deposit example with neo-go:

neo-go contract invokefunction -r http://neo3-preview.go.nspcc.ru:20332 \
-w wallet.json -a NcrE6C1mvScQpAnFctK1Mw7P7i1buLCKav \

Configure

Then configure docker-compose.yml file. Change endpoints values. Both of them should contain your public IP.

     environment:
       - NEOFS_NODE_ADDRESS=192.168.140.1:36512
       - NEOFS_GRPC_ENDPOINT=192.168.140.1:36512

It is recommended to pass node's key as a file. To do so convert your wallet WIF to 32-byte hex (via neofs-cli for example) and save it in file.

// Print WIF in a 32-byte hex format
$ neofs-cli util keyer Kwp4Q933QujZLUCcn39tzY94itNQJS4EjTp28oAMzuxMwabm3p1s
PrivateKey      11ab917cd99170cb8d0d48e78fca317564e6b3aaff7f7058952d6175cdca0f56

ScriptHash3.0BE 672e9534ead7739fe43016420f82358a3967d665

// Save 32-byte hex into a file
$ echo '11ab917cd99170cb8d0d48e78fca317564e6b3aaff7f7058952d6175cdca0f56' | xxd -r -p > my_wallet.key

Then specify path to this file in docker-compose

     volumes:
      - neofs_storage:/storage
      - ./my_wallet.key:/node.key

You also can provide WIF directly with NEOFS_NODE_KEY=Kwp4Q933QujZLUCcn39tzY94itNQJS4EjTp28oAMzuxMwabm3p1s env in docker-compose.

Start

Run node with docker-compose up command and stop it with docker-compose down.
