Rpc Node

Setup

Run the init.sh script to initialize the deployment for the first time. Select rpc node and the network to run (eon or gobi).

./scripts/init.sh

The script will generate the required deployment files under the deployments directory and provide instructions on how to run the compose stack.

Running the stack

docker compose -f deployments/rpc/[eon|gobi]/docker-compose.yml up -d

Other useful docker commands

  • Run the following command to stop the stack: 
    docker compose -f deployments/rpc/[eon|gobi]/docker-compose.yml stop
  • Run the following command to start the stack again: 
    docker compose -f deployments/rpc/[eon|gobi]/docker-compose.yml up -d
  • Run the following command to stop the stack and delete the containers: 
    docker compose -f deployments/rpc/[eon|gobi]/docker-compose.yml down
  • Run the following commands to destroy the stack, this action will delete your wallet and all the data: 
    docker compose -f deployments/rpc/[eon|gobi]/docker-compose.yml down
docker volume ls # List all the volumes
docker volume rm [volume_name] # Remove the volumes related to your stack, these volumes are named after the stack name: [COMPOSE_PROJECT_NAME]_[volume-name]

Rpc Node Usage

  • The evmapp node RPC interfaces will be available over HTTP at http://localhost:9545/. For example:

    curl -sX POST -H 'accept: application/json' -H 'Content-Type: application/json' "http://127.0.0.1:9545/block/best"

  • The Ethereum RPC interface is available at /ethv1 location http://localhost:9545/ethv1. For example:

    curl -sX POST -H 'accept: application/json' -H 'Content-Type: application/json' -d '{"jsonrpc":"2.0","method":"eth_gasPrice","params":[],"id":1}' "http://127.0.0.1:9545/ethv1"

  • The RPC and WebSocket ports are only exposed locally (accessible only via localhost). In order to expose those ports outside the local environment, you can edit the following lines in the docker-compose.yml file:

    • Default configuration(locally exposed):

         - "127.0.0.1:${SCNODE_WS_SERVER_PORT}:${SCNODE_WS_SERVER_PORT}"
   - "127.0.0.1:${SCNODE_REST_PORT}:${SCNODE_REST_PORT}"

    • Edit the lines in the following way to expose the ports externally:

         - "${SCNODE_WS_SERVER_PORT}:${SCNODE_WS_SERVER_PORT}"
   - "${SCNODE_REST_PORT}:${SCNODE_REST_PORT}"
