N3 Testnet Storage node configuration

There is a prepared configuration for NeoFS Storage Node deployment in N3 Testnet. The easiest way to deploy a Storage Node is to use the prepared docker image and run it with docker-compose.

Build image

Prepared frostfs-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
...

Deploy node

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

Deposit

The Storage Node owner should deposit GAS to NeoFS smart contract. It generates a bit of sidechain GAS in the node's wallet. Sidechain GAS is used to send bootstrap tx.

First, obtain GAS in N3 Testnet chain. You can do that with faucet service.

Then, make a deposit by transferring GAS to NeoFS contract in N3 Testnet. You can provide scripthash in the data argument of transfer tx to make a deposit to a specified account. Otherwise, deposit is made to the tx sender.

NeoFS contract scripthash in N3 Testnet is b65d8243ac63983206d17e5221af0653a7266fa1, so the address is NadZ8YfvkddivcFFkztZgfwxZyKf1acpRF.

See a deposit example with neo-go.

neo-go wallet nep17 transfer -w wallet.json -r https://rpc01.testnet.n3.nspcc.ru:21331 \
--from NXxRAFPqPstaPByndKMHuC8iGcaHgtRY3m \
--to NadZ8YfvkddivcFFkztZgfwxZyKf1acpRF \
--token GAS \
--amount 1

Configure

Next, configure node_config.env file. Change endpoints values. Both should contain your public IP.

NEOFS_GRPC_0_ENDPOINT=65.52.183.157:36512
NEOFS_NODE_ADDRESSES=65.52.183.157:36512

Set up your UN/LOCODE attribute.

NEOFS_GRPC_0_ENDPOINT=65.52.183.157:36512
NEOFS_NODE_ADDRESSES=65.52.183.157:36512
NEOFS_NODE_ATTRIBUTE_2=UN-LOCODE:RU LED

You can validate UN/LOCODE attribute in NeoFS LOCODE database with frostfs-cli.

$ frostfs-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 the node's key as a file. To do so, convert your wallet WIF to 32-byte hex (via frostfs-cli for example) and save it to a file.

// Print WIF in a 32-byte hex format
$ frostfs-cli util keyer Kwp4Q933QujZLUCcn39tzY94itNQJS4EjTp28oAMzuxMwabm3p1s

$ echo '11ab917cd99170cb8d0d48e78fca317564e6b3aaff7f7058952d6175cdca0f56' | xxd -r -p > my_wallet.key

Then, specify the path to this file in docker-compose.yml

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

NeoFS objects will be stored on your machine. By default, docker-compose is configured to store objects in named docker volume frostfs_storage. You can specify a directory on the filesystem to store objects there.

     volumes:
       - /home/username/frostfs/rc3/storage:/storage
       - ./my_wallet.key:/node.key

Start

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

Debug

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

     environment:
       - NEOFS_LOGGER_LEVEL=debug
