How to test openethereum in dev environment

Establish node

• Fetch openethereum source code

> git clone --recursive https://github.com/openethereum/openethereum.git

• Reuse substrate-ssvm docker image as our dev environment

> docker run -it --rm \
  --name ssvm \
  -v $(pwd):/root/node \
  -w /root/node \
  secondstate/substrate-ssvm

• Build openethereum from source

(docker-1) cd openethereum/
(docker-1) cargo build --release --features final

• Establish node in dev mode and geth supported

(docker-1) ./target/release/openethereum --geth --chain dev

Use geth attach our node

• Attach to container with second session and install geth

> docker exec -it ssvm bash

(docker-2) add-apt-repository -y ppa:ethereum/ethereum
(docker-2) apt-get update
(docker-2) apt-get install ethereum

• Use geth attach node

(docker-2) geth attach

• Test node

(geth-shell) personal.listAccounts

• Should give a result like

["0x00a329c0648769a73afac7f9381e08fb43dbea72"]

• Or you can execute JS script as below

(docker-2) geth --exec 'loadScript("./geth_example3.js")' attach
