Smoke Testsnpm (tag) Environment Variables Made With License

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: It's recomended to start using the CLI Tool.

Requirements

  • Node.js >= v14.x
    • Node version check: node -v
  • NPM >= v6.14.17
    • NPM version check: npm -v
  • Docker >= v20.10.x
    • Docker version check: docker -v
  • Docker Compose => v2.12.2
    • Docker Compose version check: docker compose version
  • Minimum 16GB RAM

Note:

  • Ensure the VirtioFS file sharing implementation is enabled 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: 8GB
    • Swap: 1 GB
    • Disk Image Size: 64 GB

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

CLI Tool - @hashgraph/hedera-local

What

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

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 @hashgraph/hedera-local -g

Local Development Installation

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 npm

npm run start to start the network npm run restart to restart the network npm run stop to stop the network npm run generate-accounts to generate new account for already started network

NOTE: If you want to use any of the CLI options listed below, you'd need to pass -- after npm run start (for example) and then specify the wanted option. For example, if you want to start in detached mode, you can use npm run start -- -d

Using hedera-local

$ hedera

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.
        options:
            --d or --detached for starting in detached mode.
            --verbose set the verbose level. Defaults to 'info' choices are "info" & "trace"
            --h or --host to override the default host.
            --n or --network to override the default configuration. Defaults to mainnet.
            --l or --limits to enable/disable the JSON-RPC relay rate limits. Defaults to true.
            --dev to enable/disable developer mode.
            --full to enable/disable full mode. Production local-node.
            --multinode     Enable or disable multi-node mode.
            --balance to set starting hbar balance of the created accounts.
            --async to enable or disable asynchronous creation of accounts.
            --b or --blocklist to enable or disable account blocklisting. Depending on how many private keys are blocklisted, this will affect the generated on startup accounts.
            --enable-debug  Enable or disable debugging of the local node [boolean] [default: false]
            --network-tag Select custom network node tag [string] [defaults: predefined selected configuration]
            --mirror-tag Select custom mirror node tag [string] [defaults: predefined selected configuration]
            --relay-tag Select custom hedera-json-rpc relay tag [string] [defaults: predefined selected configuration]
            --workdir       Path to the working directory for local node [string] [default: "[USER APP DATA]/hedera-local"]
    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.
        options:
            --h or --host to override the default host.
            --balance to set starting hbar balance of the created accounts.
            --async to enable or disable asynchronous creation of accounts.
    debug [timestamp] - Parses and prints the contents of the record file that has been created
                        during the selected timestamp.
                        Important: Local node must be started with the -g, --enable-debug flag to enable this feature

Note: Generated accounts are 3 types (ECDSA, Alias ECDSA and ED25519). All of them are usable via HederaSDK. Only Alias ECDSA accounts can be imported into wallet like Metamask or used in ethers.

Note: Read more about developer mode here

Commands

hedera start <options>

Demo

  • --accounts - Default is 10. Specify the number of accounts to generate at startup. The first 10 are with predefined private keys, and the next ones are with random generated private keys.

  • --h / --host - Override the default host.

hedera restart <options>

Demo

  • --accounts - Default is 10. Specify the number of accounts to generate at startup. The first 10 are with predefined private keys, and the next ones are with random generated private keys.

  • --h / --host - Override the default host.

hedera start -d <options>

Network specific configuration

Network specific configurations can be applied using the -n/--network option when starting/restarting the local node. Pre-configured options are mainnet, previewnet, testnet and local

To create a custom network configuration, you can edit the src/configuration/local.json with the images and properties that you want and just start the network with npm run start.

You can use it in a hardhat project by adding the following config:

defaultNetwork: 'local',
  networks: {
    local: {
      url: 'http://localhost:7546',
      accounts: [
        0x105d050185ccb907fba04dd92d8de9e32c18305e097ab41dadda21489a211524,
        0x2e1d968b041d84dd120a5860cee60cd83f9374ef527ca86996317ada3d0d03e7
      ],
      chainId: 298,
    },
    testnet: {
      url: 'https://testnet.hashio.io/api',
      accounts: [],
      chainId: 296,
    },
  },

Docker

NOTE: This will not create accounts on startup, nor will perform any kind of checks.

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

For Windows users: You will need to update the file endings of compose-network/mirror-node/init.sh by running this in WSL:

    dos2unix compose-network/mirror-node/init.sh
  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 manually generated files. If you would like to keep any files created manually 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.

      NOTE: To connect to the local consensus node from a browser you will have to use the Envoy proxy at http://127.0.0.1:50213.

  • 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. compose-network/grafana/dashboards folder contains the Grafana dashboard definitions in JSON format which will be automatically provisioned at startup.
  3. compose-network/grafana/datasources folder contains the Grafana datasource definitions in YAML format which wil be automatically provisioned at startup.
  4. network-logs folder will be created at runtime in the working directory and will have all the log files generated after starting local node.

The local node writes its ephemeral data to a working directory which can be set using the --workdir flag, and has a default value dependant on the OS of the user

OS Default Working Directory
MacOS ~/Library/Application Support/hedera-local
Linux ~/.local/share/hedera-local
Windows %USERPROFILE%\AppData\Local\hedera-local

Steps to change the memory limits, properties and other configurations

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.

Exposed Endpoints

Type Endpoint
Consensus Node Endpoint http://localhost:50211
Mirror Node GRPC Endpoint http://localhost:5600
Mirror Node REST API Endpoint http://localhost:5551
JSON RPC Relay Endpoint http://localhost:7546
JSON RPC Relay Websocket Endpoint http://localhost:8546
Mirror Node Explorer http://localhost:8080
Grafana UI http://localhost:3000

Grafana & Prometheus

Accessing Prometheus

The deployed Prometheus instance may be accessed from http://localhost:9090 and no credentials are required.

Accessing Grafana

The deployed Grafana instance may be accessed from http://localhost:3000 and the following default credentials are needed at first login:

User Name Password
admin admin

Adding New Dashboards

Creating new dashboards may be accomplished using the Grafana visual editor; however, these dashboards will not persist after a docker compose down -v command or any other command which removes the named volumes.

Dashboards may be exported as JSON definitions and placed under the compose-network/grafana/dashboards folder to ensure they are automatically restored after a docker compose down -v or equivalent operation.

Any dashboard definitions placed into the root of the compose-network/grafana/dashboards folder will appear under the General folder in the Grafana dashboard list Placing dashboards under a subfolder will result in a new folder in the Grafana dashboard list and the dashboards will be deployed under the folder.
