NeoFS CLI

NeoFS CLI is an example of tool that provides all basic interactions with NeoFS. It contains commands for container, object, storage group and accounting operations.

Getting Started

Installing NeoFS-CLI

$ go get -u github.com/nspcc-dev/neofs-cli

Building NeoFS-CLI

To build NeoFS-CLI run make build command:

$ git clone github.com/nspcc-dev/neofs-cli.git
$ cd neofs-cli 
$ make build
  ⇒ Ensure vendor: OK
  ⇒ Download requirements: OK
  ⇒ Store vendor localy: OK
  ⇒ Build binary into ./bin/neofs-cli

Application will be placed in bin directory

$ ./bin/neofs-cli --help

   neofs-cli [global options] command [command options] [arguments...]

VERSION:
   dev (now)

COMMANDS:
   set         set default values for key or host
   object      object manipulation
   sg          storage group manipulation
   container   container manipulation
   withdraw    withdrawals manipulation
   accounting  accounts manipulation
   status      node status info
   help, h     Shows a list of commands or help for one command

GLOBAL OPTIONS:
   --ttl value     request ttl (default: 0)
   --config value  config (default: ".neofs-cli.yml") [$NEOFS_CLI_CONFIG]
   --help, -h      show help
   --version, -v   print the version

Configuration

User can set up default key and host address values to omit typing it in every command. It can be done with environment variables.

$ env
...
NEOFS_CLI_KEY=./key
NEOFS_CLI_ADDRESS=fs.nspcc.ru:8080
...

You can set up default values within CLI application as well.

$ ./bin/neofs-cli set host fs.nspcc.ru:8080
set new value for host: "85.143.219.93:8080"

Private key may be represented as path to the file with binary encoded private key, 32-byte hex string without 0x prefix or WIF string.

$ ./bin/neofs-cli set key ./key 
set new value for key: "./key"

$ ./bin/neofs-cli set key 1dd37fba80fec4e6a6f13fd708d8dcb3b29def768017052f6c930fa1c5d90bbb
set new value for key: "1dd37fba80fec4e6a6f13fd708d8dcb3b29def768017052f6c930fa1c5d90bbb"

$ ./bin/neofs-cli set key L1ynWYewdiapfZ85bX7hNnhj65jadZcxjmHwN94ST17VrRt6G4Ki
set new value for key: "L1ynWYewdiapfZ85bX7hNnhj65jadZcxjmHwN94ST17VrRt6G4Ki"

Checking available deposit

To perform storage operations like container creation or storage payment user must have a deposit. To check available deposit run:

$ ./bin/neofs-cli accounting --host fs.nspcc.ru:8080 balance --key ./key 
Balance info:
- Active balance: 50

Container creation

To put object into NeoFS you need to create a container and define storage policy. There is an example of new container that stores data in three copies.

Application will await until container will be accepted by consensus in inner ring nodes

$ ./bin/neofs-cli container --host fs.nspcc.ru:8080 put  --key ./key \
--rule 'SELECT 3 Node'

Container processed: 7Gi7c1WmyKxEW3JwqEETupNoQ7rAb1CSQYxdPirXLwaG

Trying to wait until container will be accepted on consensus...
...............
Success! Container <7Gi7c1WmyKxEW3JwqEETupNoQ7rAb1CSQYxdPirXLwaG> created.

Object operations

User can upload the object when container is created. You can specify user headers that will be put into object's header.

$ ./bin/neofs-cli object --host fs.nspcc.ru:8080 put  --key ./key \
--cid 7Gi7c1WmyKxEW3JwqEETupNoQ7rAb1CSQYxdPirXLwaG \
--file ./cat_picture.png \
--user "Nicename"="cat_picture.png"

[./cat_picture.png] Sending header...
[./cat_picture.png] Sending data...

  CID: 7Gi7c1WmyKxEW3JwqEETupNoQ7rAb1CSQYxdPirXLwaG

All correctly uploaded objects are accessible from CLI application.

$ ./bin/neofs-cli object --host fs.nspcc.ru:8080 get \
--cid 7Gi7c1WmyKxEW3JwqEETupNoQ7rAb1CSQYxdPirXLwaG \
--oid e35f3596-2cde-4d3e-b57a-752ed687b79a \
--file ./cat_from_neofs.png

$ md5sum cat_from_neofs.png cat_picture.png

ca940fbc2b7031bd07b510baf397ab01  cat_picture.png

You can get object's headers without downloading it from NeoFS.

$ ./bin/neofs-cli object --host fs.nspcc.ru:8080 head \
--cid 7Gi7c1WmyKxEW3JwqEETupNoQ7rAb1CSQYxdPirXLwaG \
--oid e35f3596-2cde-4d3e-b57a-752ed687b79a \

You can also search by well known or user defined headers

$ ./bin/neofs-cli object --host fs.nspcc.ru:8080 search \

Storage group operations

Storage group contains meta information for data audit. If nodes are not receiving payments, they will eventually delete objects. To prevent this user should create storage group for it's objects.

$ ./bin/neofs-cli sg --host fs.nspcc.ru:8080 put --key ./key \
--cid 7Gi7c1WmyKxEW3JwqEETupNoQ7rAb1CSQYxdPirXLwaG \
--oid e35f3596-2cde-4d3e-b57a-752ed687b79a \
--oid 79ecc573-92c9-4066-8546-96e16e980700

        CID: 7Gi7c1WmyKxEW3JwqEETupNoQ7rAb1CSQYxdPirXLwaG

You can list created storage groups,

$ ./bin/neofs-cli sg --host fs.nspcc.ru:8080 list \ 
--cid 7Gi7c1WmyKxEW3JwqEETupNoQ7rAb1CSQYxdPirXLwaG

Container ID: Object ID

and look for details. Storage group is stored as an object in the container.

$ ./bin/neofs-cli sg --host fs.nspcc.ru:8080 get \
--cid 7Gi7c1WmyKxEW3JwqEETupNoQ7rAb1CSQYxdPirXLwaG \
