Bootnode and miner

Running "server" (bootnode)

Build and run

docker build -t bootnode .
docker run -d -p 30303:30303 -p 30303:30303/udp --name bootnode bootnode

This will run container bootnode and expose port 30303. Make port 30303 available from Internet.

Note: Container also will create an account and start mining immediately.

Entering geth JS console on bootnode

Execute geth attach in interactive mode:

docker exec -it bootnode geth attach ipc:/home/datadir/geth.ipc

Usefull commands:

• list accounts eth.accounts
• check the balance eth.getBalance(eth.accounts[0])

To unlock wallet use password from src/pwd file

Getting bootnode address

Execute get_node.sh and in result string replace [::] with server's public ip address. You will get something similar to enode://b4237b154a99cc729f4731348de518410c83d0b798fa153308140e4b9a5098a5a9f116115d3fd8245038bab9f08dfd804f60724ad39af080eda9a2d4674dce6d@172.17.0.2:30303

Backup/moving the container

See docker export and import for more info.

Running client (connecting to the private blockchain network)

At the very first time initialize geth data directory by geth --datadir=datadir init src/genesis.json

Then run geth console with initialized datadir, network id and bootnode

geth --datadir=datadir --networkid 1511850993 --bootnodes enode://b4237b154a99cc729f4731348de518410c83d0b798fa153308140e4b9a5098a5a9f116115d3fd8245038bab9f08dfd804f60724ad39af080eda9a2d4674dce6d@172.17.0.2:30303 console

Replace enode://... with correct enode address (see [Getting bootnode address][] for more info).
