Horizon Ethereum Blockchain container

geth container

Build

make 

OR

make TAG=1.4.18 # optional TAG for specific geth version, otherwise defaults to latest

Client Run (for Horizon bootstrap)

export INSTANCE_NAME=client
export LOCAL_DATA_DIR=/ssd/geth_root_user
export LOCAL_PORT=8545
export RAM=128m # for 1GB system
mkdir -p $LOCAL_DATA_DIR
docker run -m $RAM -d -t --name $INSTANCE_NAME -v $LOCAL_DATA_DIR:/root -p 127.0.0.1:$LOCAL_PORT:8545 $(uname -m)/geth start.sh

NOTE: -p 127.0.0.1:$LOCAL_PORT:8545 limits RPC access to localhost only, be careful with this.

NOTE: If running more than a single instance, then you must have different $INSTANCE_NAME, $LOCAL_DATA_DIR, and $LOCAL_PORT variables.

Miner Run

export INSTANCE_NAME=miner
export LOCAL_DATA_DIR=/ssd/geth_root_user
export LOCAL_PORT=8545
export EXTNIC=eth0
export EXTIP=$(ip addr show dev $EXTNIC | grep 'inet ' | awk '{print $2}' | awk -F/ '{print $1}')
export PORT=30303
mkdir -p $LOCAL_DATA_DIR
# Run only once!  A 2nd run will destroy your chain.
docker run --rm -it --name $INSTANCE_NAME -v $LOCAL_DATA_DIR:/root -p 127.0.0.1:$LOCAL_PORT:8545 $(uname -m)/geth genesis.sh
# Can kill and restart without issue
docker run -d -t --name $INSTANCE_NAME -v $LOCAL_DATA_DIR:/root -p 127.0.0.1:$LOCAL_PORT:8545 -p $PORT:$PORT -p $PORT:$PORT/udp -e EXTIP=$EXTIP $(uname -m)/geth miner.sh

NOTE: -p 127.0.0.1:$LOCAL_PORT:8545 limits RPC access to localhost only, be careful with this.

NOTE: If running more than a single instance, then you must have different $INSTANCE_NAME, $LOCAL_DATA_DIR, $LOCAL_PORT, and $PORT variables.

You'll need the enode and network ID from the miner to peer with it, e.g.:

curl -sL http://127.0.0.1:8545 -X POST --data '{"jsonrpc":"2.0","method":"admin_nodeInfo","params":[],"id":1}' | jq -r '.result.protocols.eth.network'
913172220

# curl -sL http://127.0.0.1:8545 -X POST --data '{"jsonrpc":"2.0","method":"admin_nodeInfo","params":[],"id":1}' | jq -r '.result.enode'
enode://12f518053bc6a8c54cb9c26c1948cdadece60988a6bfb5423038c4ed14252f132eb02202f541fb83457d0e81c8ecb42bf7ea2588a78f1990a96f9620e6c52990@199.88.179.63:30303

Client Run (hack for adhoc miner)

cp geth.sh gethadhoc.sh
mkdir -p /root/.colonus # put genesis.json in here from $EXTIP:$LOCAL_DATA_DIR above

Optional pre-gen account setup:

mkdir -p /root/.ethereum/keystore
# copy from from $EXTIP:$LOCAL_DATA_DIR above accountN, keydataN.b64, keynameN.b64, and passwdN to /tmp
# e.g. for N = 1
cp /tmp/account1 /root/.colonus/accounts 
cp /tmp/passwd1 /root/.colonus/passwd 
base64 -d /tmp/keydata1.b64 >/root/.ethereum/keystore/$(base64 -d /tmp/keyname1.b64)

Edit gethadhoc.sh to look like this using the enode and network ID from above:

#!/bin/bash

. $(dirname $0)/functions

(
geth_account
PEERS=enode://12f518053bc6a8c54cb9c26c1948cdadece60988a6bfb5423038c4ed14252f132eb02202f541fb83457d0e81c8ecb42bf7ea2588a78f1990a96f9620e6c52990@199.88.179.63:30303
NETWORKID=913172220
geth_init
geth_process $NETWORKID $PEERS
) 2>&1 | sed -u 's/^/GETH: /'

Run:

./handout.sh & ./unlock.sh & ./blockmon.sh & ./gethadhoc.sh

NOTE: ./handout.sh will do nothing since there is no ATM with this setup. Use a pre-gen account or manually xfer funds.

Debug

docker logs -f $INSTANCE_NAME

Stop

docker rm -f $INSTANCE_NAME
