Start Node

Information

The GNY docker image will be pulled from dockerhub repository gnyio/node (opens new window)

With Docker

To get up and running you will need to create a docker-compose.yml file.

Create a new file docker-compose.yml:

touch docker-compose.yml

Copy the following content into your docker-compose.yml file and change the environment variables:

version: "3.3"
services:
  db1:
    image: "postgres:9.6.12"
    container_name: "db1"

Edit docker-compose.yml file

In order to make the docker-compose.yml file work you need to edit the following properties:

Property	Description	Formatting tips
GNY_PUBLIC_IP=214.42...	replace with your public ip	don't double quote public ip
GNY_SECRET=health typical...	twelve word BIP39 (opens new window) forging secret -	don't double quote your secret
GNY_P2P_SECRET="CAASqgkwggSm..."	libp2p (opens new window) secret	double quote value

See Configure for more details.

Now start both services (db1, node1) with:

sudo docker-compose up --detach

TIP

For information on how to forge Blocks see configure

Result

This will start a GNY Blockchain.

This node will later connect to other nodes on the network.
