# N3 Testnet Storage node configuration
There is a prepared configuration for NeoFS Storage Node deployment in
N3 testnet RC3. The easiest way to deploy Storage Node is to use prepared
docker image 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 ab0557117b02
Successfully tagged nspccdev/neofs-storage-testnet:0.24.0
```
## Deploy node
To run storage node in N3 testnet RC3 environment you should deposit GAS assets,
update docker-compose file and start the node.
### Deposit
Storage Node owner should deposit GAS to NeoFS smart contract. 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 RC3 chain. You can do that with
[faucet](https://neowish.ngd.network) service.
Then make a deposit by transferring GAS to NeoFS contract in N3 testnet RC3.
You can provide scripthash in the `data` argument of transfer tx to make a
deposit to specified account. Otherwise, deposit is made to tx sender.
NeoFS contract scripthash in NEO testnet RC3 is `088c76a08c7b4546582fe95df1ba58f61f165645`,
so the address is `NSEawP75SPnnH9sRtk18xJbjYGHu2q5m1W`
See a deposit example with `neo-go`.
```
neo-go wallet nep17 transfer -w wallet.json -r https://rpc1.n3.nspcc.ru:20331 \
--from NXxRAFPqPstaPByndKMHuC8iGcaHgtRY3m \
--to NSEawP75SPnnH9sRtk18xJbjYGHu2q5m1W \
--token GAS \
--amount 1
```
### Configure
Then configure `node_config.env` file. Change endpoints values. Both
should contain your **public** IP.
```
NEOFS_NODE_ADDRESS=65.52.183.157:36512
NEOFS_GRPC_ENDPOINT=65.52.183.157:36512
```
Set up your [UN/LOCODE](https://unece.org/trade/cefact/unlocode-code-list-country-and-territory)
attribute.
```
NEOFS_NODE_ADDRESS=65.52.183.157:36512
NEOFS_GRPC_ENDPOINT=65.52.183.157:36512
NEOFS_NODE_ATTRIBUTE_1=UN-LOCODE:RU LED
```
You can validate UN/LOCODE attribute in
[NeoFS LOCODE database](https://github.com/nspcc-dev/neofs-locode-db/releases/tag/v0.1.0)
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 to file.
```
// Print WIF in a 32-byte hex format
$ neofs-cli util keyer Kwp4Q933QujZLUCcn39tzY94itNQJS4EjTp28oAMzuxMwabm3p1s

// Save 32-byte hex into a file
$ echo '11ab917cd99170cb8d0d48e78fca317564e6b3aaff7f7058952d6175cdca0f56' | xxd -r -p > my_wallet.key
```
Then specify path to this file in `docker-compose.yml`
```yaml
volumes:
- neofs_storage:/storage
- ./my_wallet.key:/node.key
```
NeoFS objects will be stored on your machine. By default, docker-compose
configured to store objects in named docker volume `neofs_storage`. You can
specify directory on the filesystem to store objects there.
```yaml
volumes:
- /home/username/neofs/rc3/storage:/storage
- ./my_wallet.key:/node.key
```
### 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:
```yaml
environment:
- NEOFS_LOGGER_LEVEL=debug
```
