Ethereum Geth and Lighthouse Connection Problem
The Ethereum network is based on the Blockchain Geth motor to perform transactions, manage accounts and validate intelligent contracts. The Geth customer is responsible for the interaction with Ethereum Mainnet, while the lighthouse provides a safe development environment (SDE) for the writing and test of Ethereum contracts.
Vulnerability in Docker composed

However, there is a problem that produces in your docker-compound.yml 'file which could potentially lead to connection problems between the Geth container and the lighthouse containers. In particular:
- The lighthouse 'service is not correctly configured to connect to the Geth' service.
- The servicesETHERSCAN-API
IT IS INFURE.
Resolution of the connection problem
To solve this problem, you need to add the necessary configurations for LightHouse and Ethereum Mainnet. Here is adocker-comparish.yml ‘updated file that should solve the problem of the connection:
`Yaml
Version: ‘3’
Services:
Geth:
Container_name: Geth
Volumes:
– /mnt/external/geth:/root/.ethereum
-/MNT/Geth-Data:/Var/Lib/Eterscan
lighthouse:
Image: Ethereum/Go-Ethereum/Lighthouse: V1.0
Doors:
– “8080: 8080”
depend_on:
– Geth
environment:
– Etherscan_api_key = Your_etherescan_api_key
– Infura_project_id = Your_infura_project_id
Etherscan-API:
Image: Ethereum/Go-Ethereum/Etherscan-API: V1.4.2
Doors:
– “8543: 8543”
Infura.io:
Image: Ethereum/Go-Ethereum/Infura-Go: V0.24.2
Doors:
– “5008: 5008”
`
In this filedocker-comparison.yml ‘updated:
- We added the configurations necessary for Faro and Ethereum Mainnet.
- The image
Etherscan-API 'is used to establish a connection with the Ethereum API.
- The image is infra.o it is used to connect to the mild network.
- The variables of the environment
Etherscan_api_keyis infura_project_idare set for each service.
execution of the updated composition file
After updating thedocker- composed.yml ‘, you can perform it using:
`Bash
Docker -Ist Up -D -Build
`
This will start all the services in detached mode and build the Docker images if they are not already built.
Once the services are running, you should be able to access the lighthouse by visitinghttp: // Localhost: 8080(assuming that the container 'Geth is running on the door 8551). Can you also use the Endpoint API Ethereum by visiting https: //api.etherscan.io/api/? Action = List+blockchain+logs & apikey = Your_etherescan_api_key.
By adding these configurations to the `docker- composed file.yml ‘, you should now be able to connect Lighthouse to the Geth container and access Ethereum Mainnet.
