Development environment to work with Ethereum's Geth

Primary LanguageDockerfile

Ethereum Geth dev

I created this repo when I started working with Solidity in the Ethereum's network. Its not updated for a long time and shoudn't be used as a reference.

Running Geth on ethereum's imagem (Limited shell)

docker run -d --name ethereum-node -v ~/development/ethereum:/srv \
-p 8545:8545 -p 30303:30303 -w="/srv" ethereum/client-go \
--datadir aula_web --dev --rpc \
--rpcapi "admin,db,eth,debug,miner,net,shh,txpool,personal,web3" \
--rpcaddr "0.0.0.0" \
--rpcport "8545" \
--rpccorsdomain "*"

Dockerfile

Building the container:

$ docker build -t ethereum-geth-vm .

Running the container:

docker run -it -p 8545:8545 -p 30303:30303 -p 9000:9000 \
-v ~/development/ethereum:/srv -w="/srv" --name ethereum-geth ethereum-geth-vm bash

Get container's shell:

docker exec -it ethereum-geth-vm bash

Starting geth:

geth --datadir aula_web --dev --rpc \
--rpcapi "admin,db,eth,debug,miner,net,shh,txpool,personal,web3" \
--rpcaddr "0.0.0.0" \
--rpcport "8545" \
--rpccorsdomain "*"

Or run using Docker Composer

Starting service:

$ docker-compose up -d

Geth

Execute this commands inside the container or on your local env

  • Starting geth on dev mode
geth --datadir aula_web --dev --rpc \
--rpcapi "admin,db,eth,debug,miner,net,shh,txpool,personal,web3" \
--rpcaddr "0.0.0.0" \
--rpcport "8545" \
--rpccorsdomain "*"

Enabling WebSocket:

-ws Enable the WS-RPC server
--wsaddr value WS-RPC server listening interface (default: "localhost")
--wsport value WS-RPC server listening port (default: 8546)
--wsapi value API's offered over the WS-RPC interface

Open Zepellin -> Token ERC20

ABI is the interface, I dont need the ABI for a ERC20 token because it implements the interface, I just need the contractTx

Solidity Modifiers

payable -> makes the function accept tokens

pragma solidity 0.4.24;

contract PersonTest {
    
    address public owner;
    uint public created_at;
    uint public id_person;
    
    string public name;
    string public email;
    
    event LogUpdateEmail(address _addressPerson, string _newEmail);
    
    constructor(string _name, string _email) public {
        name = _name;
        email = _email;
        owner = msg.sender;
        created_at = now; // Comes from miner time
    }
}
