swarm-driver

This is an implementation of docker storage driver on the swarm

In order to run this we need to clone 3 repos:

1. This repo with the driver implementation

git clone https://github.com/uncloud-registry/swarm-driver.git

2. The distribution repo

git clone https://github.com/uncloud-registry/distribution.git

3. The modified swarm client

git clone https://github.com/aloknerurkar/bee.git

NOTE: The driver and distribution repos should be in the same directory as we use local dependency in go

Step 1

Build the modified bee client. This has a small fix which allows deferred uploads of SOCs.

cd bee
make binary

Step 2

Create the config for the bee node and start it. Example testnet config:

api-addr: ':1633'
p2p-addr: ':1634'
password: aaa4eabb0813df71afa45d
data-dir: ~/.bee-testnet
cors-allowed-origins:
  - '*'
verbosity: '5'
bootnode: ["/dnsaddr/testnet.ethswarm.org"]
full-node: 'false'
swap-enable: 'true'
mainnet: false
blockchain-rpc-endpoint: <block chain RPC endpoint for sepolia/gnosis>
storage-incentives-enable: 'false'
use-postage-snapshot: false
network-id: 10
swap-initial-deposit: '1000000000000000000'

• Fund the account

  Check bee docs on how to fund the node on testnet/mainnet.

• Buy a postage stamp

  The registry has to be initialized with a postage stamp. You can buy once you have funds and the node is synced with the network.

  curl -X POST http://localhost:1633/stamps/1000000000/24
  

Step 3

Build the distribution docker image. The current dockerfile is copied during the build. So there is a config-testnet.yaml file in the distribution repo which will be copied.

Example:

version: 0.1
log:
  level: debug
  fields:
    service: registry
    environment: development
storage:
    delete:
      enabled: true
    cache:
        blobdescriptor: inmemory
    swarm:
        inmemory: false
        encrypt: false
        privateKey: <HEX encoded private key for publishing updates for the registry SOCs>
        cache: true
        host: "127.0.0.1" <IP of the machine where bee node is runninng>
        port: 1633 <PORT no where the API is running on bee>
        batchID: <POSTAGE STAMP ID>
    maintenance:
        uploadpurging:
            enabled: false
    tag:
      concurrencylimit: 8
http:
    addr: :5000
    debug:
        addr: :5001
        prometheus:
            enabled: true
            path: /metrics
    headers:
        X-Content-Type-Options: [nosniff]
health:
  storagedriver:
    enabled: true
    interval: 10s
    threshold: 3

• Generating private key for SOC owner account

  openssl ecparam -genkey -name secp256k1 -out private_key.pem
  

• Get HEX encoding

  openssl ec -in private_key.pem -outform DER -out private_key.der
  xxd -p private_key.der | tr -d '\n'
