NeoFS Admin Tool

Overview

Admin tool provides an easier way to deploy and maintain private installation of NeoFS. Private installation provides a set of N3 consensus nodes, NeoFS Alphabet, and Storage nodes. Admin tool generates consensus keys, initializes the sidechain, and provides functions to update the network and register new Storage nodes.

Build

To build binary locally, use make bin/neofs-adm command.

For clean build inside a docker container, use make docker/bin/neofs-adm.

Build docker image with make image-adm.

At NeoFS private install deployment, neofs-adm requires compiled NeoFS contracts. Find them in the latest release of neofs-contract repository.

Commands

Config

Config section provides init command that creates a configuration file for private installation deployment and updates. Config file is optional, all parameters can be passed by arguments or read from standard input (wallet passwords).

Config example:

rpc-endpoint: https://address:port # sidechain RPC node endpoint
alphabet-wallets: /path            # path to consensus node / alphabet wallets storage
network:
  max_object_size: 67108864 # max size of a single NeoFS object, bytes
  epoch_duration: 240       # duration of a NeoFS epoch in blocks, consider block generation frequency in the sidechain
  basic_income_rate: 0      # basic income rate, for private consider 0
  fee:
    candidate: 0 # inner ring candidate registration fee, for private installation consider 0
    container: 0 # container creation fee, for private installation consider 0
    container_alias: 0 # container nice-name registration fee, for private installation consider 0
    withdraw: 0  # withdraw fee, for private installation consider 0
credentials:     # passwords for consensus node / alphabet wallets
  az: password1
  buky: password2
  vedi: password3
  glagoli: password4
  dobro: password5
  yest: password6
  zhivete: password7

FS chain

Network deployment

  • generate-alphabet generates a set of wallets for consensus and Alphabet nodes.

  • init initializes the sidechain by deploying smart contracts and setting provided NeoFS network configuration.

  • generate-storage-wallet generates a wallet for the Storage node that is ready for deployment. It also transfers a bit of sidechain GAS, so this wallet can be used for NeoFS bootstrap.

Network maintenance

  • dump-names allows to walk through NNS names and see their expirations.

  • set-config add/update configuration values in the Netmap contract.

  • force-new-epoch increments NeoFS epoch number and executes new epoch handlers in NeoFS nodes.

  • renew-domain updates expiration date of the given domain for one year.

  • refill-gas transfers sidechain GAS to the specified wallet.

  • update-contracts updates contracts to a new version.

Container migration

If a network has to be redeployed, these commands will migrate all container meta info. These commands do not migrate actual objects.

  • dump-containers saves all containers and metadata registered in the container contract to a file.

  • restore-containers restores previously saved containers by their repeated registration in the container contract.

  • list-containers output all containers ids.

Network info

  • dump-config prints NeoFS network configuration.

  • dump-hashes prints NeoFS contract addresses stored in NNS.
