The Hedera Local Node project allows developers to set up their own local network. The local network is composed of one mirror node and one consensus node. You can set this up by either using the CLI tool or by running Docker.

Note: This currently does not map to the latest mirror node version or mainnet consensus node version. An issue has been opened to address this.

Docker

Requirements

  • Node.js >= v14.x and <= v16.x
    • Node version check: node -v
  • NPM >= v6.14.17 and <= v8.5.0
    • NPM version check: npm -v
  • Docker >= v20.10.x
    • Docker version check: docker -v
  • Docker Compose => v1.28.0 && <= 1.29.2
    • Docker Compose version check: docker-compose -v

Note:

  • Ensure to use Docker Compose version 1.29.2 on macOS, due to known bug in Docker Compose V2.
  • Ensure the gRPC FUSE for file sharing and Use Docker Compose V2 settings are disabled in the docker settings.

Note: The image may look different if you are on a different version docker-compose-settings.png

  • Ensure the following configurations are set at minimum in Docker Settings -> Resources and are available for use
    • CPUs: 6
    • Memory: 5GB
    • Swap: 1 GB
    • Disk Image Size: 59.6 GB

Note: The image may look different if you are on a different version settings.png

Start Your Local Network

  1. Clone the hedera-local-node repo
git clone https://github.com/hashgraph/hedera-local-node.git
  1. CD to the hedera-local-node directory
    cd hedera-local-node
  1. Run docker-compose up -d from the terminal to get the network up and running
  2. Set-up your local network client by following this tutorial

Stop Your Local Network

  1. Run docker-compose down -v; git clean -xfd; git reset --hard to stop and remove the containers, volumes and clean manuelly generated files. If you would like to keep any files created manuelly in the working directory please save them before executing this command.

Network Variables

These are the local network variables to interact with the consensus and mirror node.

  • Consensus Node Endpoint
    • 127.0.0.1:50211
    • The IP address and port of the local consensus node
  • Consensus Node Account ID
    • 0.0.3
    • The node account ID to submit transactions and queries to
  • Mirror Node GRPC Endpoint
    • 127.0.0.1:5600
    • The mirror node network to use
  • Mirror Node REST API Endpoint
    • 127.0.0.1:5551
    • The endpoint to submit rest API requests to
  • Account ID
    • 0.0.2
    • The account ID to use to pay for transactions and queries
  • Account Key
    • 302e020100300506032b65700422042091132178e72057a1d7528025956fe39b0b847f200ab59b2fdd367017f3087137
    • The private key to account 0.0.2 to sign transactions and queries with

Folder set up

  1. compose-network folder has the static files needed for starting Local network.
  2. network-logs folder will be created at runtime and will have all the log files generated after starting local node.

Steps to change the memory limits and properties

The following environment variables can be changed in the .env file for various memory limits

  1. Platform
    • PLATFORM_JAVA_HEAP_MIN
    • PLATFORM_JAVA_HEAP_MAX
  2. Consensus node
    • NETWORK_NODE_MEM_LIMIT
  3. Mirror node
    • MIRROR_GRPC_MEM_LIMIT - memory limit for mirror node gRPC
    • MIRROR_IMPORTER_MEM_LIMIT - memory limit for mirror node importer
    • MIRROR_REST_MEM_LIMIT - memory limit for mirror node rest api
    • MIRROR_WEB3_MEM_LIMIT - memory limit for mirror node web3
  4. To change application.properties, api-permission.properties or bootstrap.properties properties, update the APPLICATION_CONFIG_PATH to the location of updated config folder in .env file

IMPORTANT : Ensure to do docker-compose down -v; git clean -xfd; git reset --hard and then docker-compose up -d for the new changes to take any effect.

✘ The keys under network-node (hedera.key, hedera.crt and the keys folder) are only intended to be used for testing with this docker based local network. These keys should not be used with any other networks.

CLI Tool

@hashgraph/hedera-local

What

This package defines a basic cli commands, that can be executed via node (npx), for interacting with the Local Hedera Network.

Exposed urls are:

Consensus Node Url - 127.0.0.1:50211
Node Id - 0.0.3
Mirror Node Url - http://127.0.0.1:5551

Installation

Official NPM Release

The command below can be used to install the official release from the NPM repository. This version may not reflect the most recent changes to the main branch of this repository.

This version uses a baked in version of the Docker Compose definitions and will not reflect any local changes made to the repository.

npm install --save-dev @hashgraph/hedera-local

Local Module

The command below can be used to install the hedera-local module as a symlink against your locally checked out copy of this repository.

This is the recommended method for testing against the latest changes or a point in time version from a branch/tag.

npm install && npm install -g

Using hedera-local

$ npx hedera-local

Local Hedera Package - Runs consensus and mirror nodes on localhost:
- consensus node url - 127.0.0.1:50211
- node id - 0.0.3
- mirror node url - http://127.0.0.1:5551

Available commands:
    start - Starts the local hedera network.
    stop - Stops the local hedera network and delete all the existing data.
    restart - Restart the local hedera network.
    generate-accounts <n> - Generates N accounts, default 10.

Note: Generated accounts are 3 types. All of them are usable via HederaSDK or @hashgraph/hethers. Only Alias ECDSA accounts can be imported into wallet like Metamask or used in ethers.

Commands

Note: There are known issues with this command. Please see issue #43 and issue #33.

npx hedera-local start <options>

$ npx hedera-local start
