Connection problem Ethereum Geth and Lighthouse

The Ethereum network is based on the Geth Blockchain engine to execute transactions, manage accounts and validate intelligent contracts. The Geth client is responsible for interaction with the Mainnet Ethereum, while Lighthouse provides a secure development environment (SDE) for writing and testing Ethereum contracts.

Vulnerability in Docker composes

However, there is a brewing problem in your docker-compose file.Ym ‘which could potentially cause connection problems between the Geth container and the headlight containers. Specifically:

The “Lighthouse” service is not properly configured to connect to the Geth service".

TheEtherscan-Ami andinfura.io services are not included in the Docker-Complete.ym ‘file.

Correction of the connection problem

Ethereum: Geth and lighthouse - connection problem

To solve this problem, you must add the necessary configurations for the lighthouse and the Ethereum. Here is a docker-compose file.Ym ‘update that should solve the connection problem:

`Yaml



Version: '3'

services:

  Geth:

    contain_name: geth

    Volumes:

      - /mnt/external/geth:/root/.ethereum

      - / MNT / GETH-DATA: / VAR / LIB / ETHERSCAN

  lighthouse:

    Image: Ethereum / Go-etreum / Lighthouse: V1.0

    Ports:

      - "8080: 8080"

    Denfend_on:

      - Geth

    environment:

      - Etherscan_api_Key = Yot_etherescan_api_key

      - infura_project_id = your_infura_project_id

  Etherscan-dep:

    Image: Ethereum / Go-Ethereum / Etherscan-dep: V1.4.2

    Ports:

      - "8543: 8543"

  Infura.io:

    Image: Ethereum / Go-Ethereum / Infura-Go: V0.24.2

    Ports:

      - "5008: 5008"

'



In this docker-compose file.ym 'update:


We added the necessary configurations for Lighthouse and Ethereum MAINNET.



The image "Etherscan-dep" is used to establish a connection with the Ethereum API.

Theinfura.ioimage is used to connect to the Infura network.

The environment variablesEtherscan_Api_Keyand Infura_Project_idare defined for each service.



 Execution of the updated compound file 



After updating your Docker-compose.ym 'file, you can run it using:

bash



Docker -compose up -d -Build

'



This will start all services in detached mode and create Docker images if they are not already built.

Once the services are running, you should be able to access Lighthouse by visitinghttp: // Localhost: 8080 ‘(assuming that the containerGethworks on port 8551). You can also use the Ethereum API termination point by visitinghttps: //api.etherscan.io/Api/? Action = List + Blockchain + Logs & Apikey = your_etherescan_api_key`.

By adding these configurations to your Docker-Complete.ym ‘file, you should now be able to connect the lighthouse to the Geth container and access Mainnet Ethereum.
