Master Node Docker Setup

A guide to setup master node using docker

The easiest and most efficient way to set up a master node is by using Docker. Follow these two simple steps to set up a master node with Docker. We have provided a shell script to handle all the heavy lifting for you.

Note: This guide assumes some familiarity with the command line and running a Linux server. For a more detailed walkthrough, check out our full Master Node setup guide.

Step 1 : Create or Download the shell file

Copy the below code to a shell file master-node-deploy.sh

#!/bin/bash
  
# Define the Docker image and container name
IMAGE_NAME="beldex/beldex-master-node:v1"
CONTAINER_NAME="beldex-mn-node"
SERVICE_NAME="beldex-testnet-storage-server.service"

# Run the Docker container
echo "Running the Docker container..."
docker run --network=host --privileged --name $CONTAINER_NAME -v /sys/fs/cgroup:/sys/fs/cgroup:ro -d $IMAGE_NAME

# Give Docker a moment to start the container
sleep 5

# Fetch the container ID for the given container name
CONTAINER_ID=$(docker ps -q --filter name=$CONTAINER_NAME)

# Check if any container ID is found
if [ -z "$CONTAINER_ID" ]; then
  echo "No running container found with name: $CONTAINER_NAME"
  exit 1
else
  echo "Container ID for container $CONTAINER_NAME: $CONTAINER_ID"
fi

# Define the script to update the belnet.ini file
UPDATE_SCRIPT=$(cat <<'EOF'
IP=$(curl -sS http://api.ipify.org || true)
echo "IP for belnet: $IP"

# Update the beldex.conf file
sed -i -e "s/^master-node-public-ip=.*/master-node-public-ip=$IP/" /etc/beldex/beldex.conf

PRIVATE_IP=$(ip route get 1.2.3.4 | awk '{print $7}')
echo "PRIVATE_IP for belnet: $PRIVATE_IP"

sed -i -e "s/^public-ip=.*/public-ip=$IP/" /var/lib/belnet/router/belnet.ini

sed -i -e "s/^[[:space:]]*inbound=.*/     inbound=$PRIVATE_IP/" /var/lib/belnet/router/belnet.ini
EOF
)

# Execute the update script inside the Docker container
echo "Updating the belnet.ini,beldex.conf file inside the Docker container..."
docker exec $CONTAINER_ID bash -c "$UPDATE_SCRIPT"

# Confirm the update
if [ $? -eq 0 ]; then
  echo "belnet.ini,beldex.conf file inside container $CONTAINER_NAME with ID $CONTAINER_ID has been updated successfully."
else
  echo "Failed to update belnet.ini,beldex.conf file inside container $CONTAINER_NAME with ID $CONTAINER_ID."
  exit 1
fi

# stop the service inside the Docker container
echo "Stop the service inside the Docker container..."
docker exec -it $CONTAINER_ID systemctl stop $SERVICE_NAME

# Confirm the service restart
if [ $? -eq 0 ]; then
  echo "Service $SERVICE_NAME inside container $CONTAINER_NAME with ID $CONTAINER_ID has been stoped successfully."
else
  echo "Failed to stop service $SERVICE_NAME inside container $CONTAINER_NAME with ID $CONTAINER_ID."
  exit 1
fi

wget https://deb.beldex.dev/beldex-projects/master-node-docker/master-node-deploy.sh

Step 2: Register Master Node

Make sure the node is fully synced before run this command

Check the node status

docker exec -it <CONTAINER_ID> beldexd status

You should receive an output similar to the screenshot provided. Ensure that the height of your node matches the current network height, which can be verified at Beldex Explorer. If the heights do not match, allow the node to fully sync, which may take 4-5 hours.

Prepare for Registration

Once the node is fully synced, run the below command to register the master node

docker exec -it <CONTAINER_ID> beldexd prepare_registration

After successfully running the command, you will receive an output similar to the screenshot below. To complete the registration, execute the master node command from the output in your wallet.

You can run all beldexd commands using docker. Run docker exec -it <CONTAINER_ID> beldexd --help to get the list of commands
