@hyperledger/cactus-plugin-ledger-connector-sawtooth

This plugin provides Cacti a way to interact with Sawtooth networks. Using this we can perform:

• Check plugin and sawtooth node status.
• Monitor new blocks and transactions on the ledger.

Getting Started

Clone the git repository on your local machine. Follow these instructions that will get you a copy of the project up and running on your local machine for development and testing purposes.

Prerequisites

In the root of the project to install the dependencies execute the command:

npm run configure

Usage

Before running the connector please ensure that Sawtooth node is running and that connector will have direct access to it. Access through a proxy is not supported yet (see https://sawtooth.hyperledger.org/docs/1.2/sysadmin_guide/rest_auth_proxy.html). To use this import public-api and create new PluginLedgerConnectorSawtooth.

const connector = new PluginLedgerConnectorSawtooth({
  instanceId: uuidV4(),
  logLevel: testLogLevel,
  sawtoothRestApiEndpoint: ledgerRestApi,
  watchBlocksPollTime,
});

You can make calls through the connector to the plugin API:

async getStatus(): Promise<StatusResponseV1>

Please note that deployContract() and transact(), although available to call, are not implemented and will throw error on runtime!

SawtoothApiClient

All connector API endpoints are defined in open-api specification. You can use SawtoothApiClient to call remote sawtooth connector functions. It also contain additional utility functions to ease integration.

REST Functions

See DefaultApi for up-to-date listing of supported endpoints.

• getStatusV1

Asynchronous Functions (socket.io)

• watchBlocksV1

Running the tests

To check that all has been installed correctly and that the plugin has no errors run jest test suites.

• Run this command at the project's root:

npx jest cactus-plugin-ledger-connector-sawtooth

Building/running the container image locally

In the Cactus project root say:

DOCKER_BUILDKIT=1 docker build -f ./packages/cactus-plugin-ledger-connector-sawtooth/Dockerfile . -t cplcb

Build with a specific version of the npm package:

DOCKER_BUILDKIT=1 docker build --build-arg NPM_PKG_VERSION=0.4.1 -f ./packages/cactus-plugin-ledger-connector-sawtooth/Dockerfile . -t cplcb

Running the container

Launch container with plugin configuration as an environment variable:

docker run \
  --rm \
  --publish 3000:3000 \
  --publish 4000:4000 \
  --env AUTHORIZATION_PROTOCOL='NONE' \
  --env AUTHORIZATION_CONFIG_JSON='{}' \
  --env PLUGINS='[{"packageName": "@hyperledger/cactus-plugin-ledger-connector-sawtooth", "type": "org.hyperledger.cactus.plugin_import_type.LOCAL", "action": "org.hyperledger.cactus.plugin_import_action.INSTALL",  "options": {"rpcApiHttpHost": "http://localhost:8545", "instanceId": "some-unique-sawtooth-connector-instance-id"}}]' \
  cplcb

Launch container with plugin configuration as a CLI argument:

docker run \
  --rm \
  --publish 3000:3000 \
   --publish 4000:4000 \
  cplcb \
    ./node_modules/@hyperledger/cactus-cmd-api-server/dist/lib/main/typescript/cmd/cactus-api.js \
    --authorization-protocol='NONE' \
    --authorization-config-json='{}' \
    --plugins='[{"packageName": "@hyperledger/cactus-plugin-ledger-connector-sawtooth", "type": "org.hyperledger.cactus.plugin_import_type.LOCAL", "action": "org.hyperledger.cactus.plugin_import_action.INSTALL",  "options": {"rpcApiHttpHost": "http://localhost:8545", "instanceId": "some-unique-sawtooth-connector-instance-id"}}]'

Launch container with configuration file mounted from host machine:

echo '{"authorizationProtocol":"NONE","authorizationConfigJson":{},"plugins":[{"packageName":"@hyperledger/cactus-plugin-ledger-connector-sawtooth","type":"org.hyperledger.cactus.plugin_import_type.LOCAL","action":"org.hyperledger.cactus.plugin_import_action.INSTALL","options":{"rpcApiHttpHost":"http://localhost:8545","instanceId":"some-unique-sawtooth-connector-instance-id"}}]}' > cactus.json

docker run \
  --rm \
  --publish 3000:3000 \
  --publish 4000:4000 \
  --mount type=bind,source="$(pwd)"/cactus.json,target=/cactus.json \
  cplcb \
    ./node_modules/@hyperledger/cactus-cmd-api-server/dist/lib/main/typescript/cmd/cactus-api.js \
    --config-file=/cactus.json
