## 2. Interact with geth

If you want to start mining or stop mining you need to connect to the node via:
To get attached to the `geth` JavaScript console on the node you can run the following
```
docker exec -it ethereumdocker_eth_1 geth attach ipc://root/.ethereum/devchain/geth.ipc
```
Replace ethereumdocker_geth_1 with the container name you wish to connect to.
Then you can `miner.start()`, and then check to see if it's mining by inspecting `web3.eth.mining`.

See the [Javascript Runtime](https://github.com/ethereum/go-ethereum/wiki/JavaScript-Console) docs for more.
