Babylon Node Docker Setup

This project contains the setup for running a Babylon Node within a Ubuntu Docker container. It includes the Dockerfile for building the image and the docker-compose.yml for easy setup and management. This project is based on the excellent article from BreizhNode.

Prerequisites

• Docker
• Docker Compose
• A good internet connection for downloading dependencies
• Consequent amount of space on your hard drive / SSD (dozen of GB)

Getting Started

Step 1: Clone the Repository and setup env

Clone this repository to your local machine to get started.

git clone https://github.com/Trustia-labs/babylone-node.git
cd babylone-node

Duplicate the .env.example file and customize the NODE_NAME env variable for your node name.

cp .env.example .env
nano .env

Step 2: Build and Run the Container

In the project directory, use Docker Compose to build and start the Babylon Node.

docker-compose up -d --build

This command builds the Docker image if it hasn't been built and starts the container in detached mode.

Step 3: Verify Container is Running

Check that the container is running successfully.

docker ps

You should see your babylon-node container listed.

Post-Installation Steps

After the container is up and running, you'll need to perform a few steps inside the container to finalize the setup.

Accessing the Container

Enter the container using the following command:

docker exec -it babylon-node /bin/bash

Creating a Wallet and register your node

Check Node Synchronization

Before creating your wallet, ensure the node is fully synchronized with the network.

babylond status | jq '.sync_info.catching_up'

Wait until the catching_up value is false, indicating synchronization is complete.

Create Wallet

Create a new wallet by running:

babylond keys add wallet

Follow the prompts to secure your wallet.

Linking Wallet and Configuring Node

Link Wallet Replace with your wallet's address to link it.

babylond create-bls-key <WALLET_ADDRESS>

Configure config.toml

Adjust the timeout commit to 30s for better performance.

sed -i 's/^timeout_commit\s*=.*/timeout_commit = "30s"/' ~/.babylond/config/config.toml

Registering the Node

Before registering your node, ensure you have at least 1 $BBN in your wallet. You can find some instructions here. Be patient, the faucet can take sometimes 3 to 6 hours to deliver when crowded.

• Check Wallet Balance : Visit Babylon Explorers and enter your wallet address to verify your balance. Alternatively, you can go directly to https://testnet.babylon.explorers.guru/account/<YOUR_ADDRESS>
• Create Validator Profile : Create your validator profile in .babylond/config/validator.json. Replace placeholders with your information.

 cd .babylond/config
 touch validator.json
 nano validator.json

The content should be as follows (replace the placeholders):

{
"pubkey": "<PUBLIC_KEY>",
"amount": "1000000ubbn",
"moniker": "<NAME>",
"website": "<WEBSITE>",
"details": "<DESCRIPTION>",
"commission-rate": "0.10",
"commission-max-rate": "0.20",
"commission-max-change-rate": "0.01",
"min-self-delegation": "1"
}

• The PUBLIC_KEY comes from your previously generated wallet
• The moniker is your chosen nickname

Register Node as Validator

Run the following command:

babylond tx checkpointing create-validator .babylond/config/validator.json --chain-id="bbn-test-3" --gas="auto" --gas-adjustment="1.5" --gas-prices="0.025ubbn" --from=wallet

Monitoring and Management

• Monitoring: Access logs and monitor the node using Docker commands.
• Management: Perform routine node management tasks within the container environment.
• Support For more information, visit the Babylon official documentation or join the Babylon Discord community.
