N3 testnet RC1 storage node configuration

There is a prepared configuration for NeoFS storage node deployment in N3 testnet RC1. The easiest way to deploy storage node is to use prepared docker image of storage node and run it with docker-compose.

Build image

Prepared neofs-storage-testnet image is available at docker hub. However, if you need to rebuild it for some reason, run make image-storage-testnet command:

$ make image-storage-testnet
...
Successfully built 80ef4e3c488d
Successfully tagged nspccdev/neofs-storage-testnet:0.18.0-dirty

Deploy node

To run storage node in N3 testnet RC1 environment you should deposit GAS assets, update docker-compose file and start the node.

Deposit

Storage node holder should deposit assets because it generates a bit of side chain GAS in node's wallet. Side chain GAS used to send bootstrap tx.

First obtain GAS in N3 testnet RC1 chain. You can do that with faucet service.

Then make a deposit by invoking deposit method of NeoFS contract in N3 testnet RC1. 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 RC1 is 37a32e1bf20ed5141bc5748892a82f14e75a8e22

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 https://rpc1.n3.nspcc.ru:20331 \
-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

Also set up your UN/LOCODE attribute.

     environment:
       - NEOFS_NODE_ADDRESS=192.168.140.1:36512
       - NEOFS_GRPC_ENDPOINT=192.168.140.1:36512
       - NEOFS_NODE_ATTRIBUTE_1=UN-LOCODE:RU LED

You can check validity of your UN/LOCODE attribute in NeoFS LOCODE database with neofs-cli.

$ neofs-cli util locode info --db ./locode_db --locode 'RU LED'
Country: Russia
Location: Saint Petersburg (ex Leningrad)
Continent: Europe
Subdivision: [SPE] Sankt-Peterburg
Coordinates: 59.53, 30.15

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

// 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.

Debug

To print node logs use docker logs neofs-testnet. To print debug messages in log, setup log level to debug with this env:

     environment:
       - NEOFS_LOGGER_LEVEL=debug
