sueboy: docker-compose ethereum geth private chain

Suggestion is use docker-machine for make docker machine is more easy. VirtualBox

windows Use HFS.exe for copy file to docker machine instance.

&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp||=< genesis >
&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp||=genesis.json

1、docker-compose.yml

import：

．keystore maybe no use, because run again docker-compose need to delete /go-ether/keystore
．entrypoint must have together Dockerfile ENTRYPOINT


version: '3.3'

services:
  go-ether:
    build:
      context: go-ether/
    volumes:
      #- ./go-ether/keystore:/root/.ethereum/devchain/keystore:rw
      - ./go-ether/genesis/genesis.json:/root/genesis/genesis.json:ro
      - /etc/localtime:/etc/localtime:ro
    entrypoint: /root/start.sh
    ports:
      - "8545:8545"
      - "30303:30303"
      - "30303:30303/udp"
    networks:
      - elk

networks:
  elk:
    driver: bridge

2、Dockerfile

import：

．COPY or ADD is ok
．Only start.sh is important, other line is for test and note
．Super important is start.sh file must end LF

COPY start.sh /root/start.sh
RUN chmod +x /root/start.sh

ENTRYPOINT /root/start.sh

3、start.sh

import：

．last geth must have --minerthreads=1 , only --mini is can't mining. --mini login check geth.mining get true, but still no mining.

4、genesis.json

important：

1、genesis.json chainId & start.sh networkid must same.

2、datadir must have and same. If datadir different or no set, maybe can use same geth chain.

3、log must 2>geth.log 2>xxxooo.log xxxooo is log name.

4、--bootnodes maybe can have or not. Here is for demom, can try.

=====easy command=====

=====docker-machine=====
docker-machine --driver=virtualbox machine1 --virtualbox-memory 2048 --virtualbox-cpu-count 2 --engine-opt dns=8.8.8.8

docker-machien start machine1
docker-machien ssh machine1
docker-machien stop machine1

Move machine1 hdd to D: , stop first then use VirtualBox Media manager, don't change ini or config file.

=====docker-machine=====

=====copy edit txt file=====
On windows use HFS.exe put file into HFS.

rm -f docker-compose.yml && wget http://ip address/docker-compose.yml

rm start.sh -f && wget http://ip address/start.sh && rm -f Dockerfile && wget http://ip address/Dockerfile && rm genesis/genesis.json -f && wget -O genesis/genesis.json http://ip address/genesis.json

=====copy edit txt file=====

=====docker-compose=====
sudo curl -L "https://github.com/docker/compose/releases/download/1.22.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose

．clear cache
chose 1：docker-compose rm -f && docker-compose pull && docker-compose up --build -d && docker-compose up
chose 2：docker-compose up --force-recreate

I use chose 1.
=====docker-compose=====

======login docker======
docker ps

xxxooo is docker container id, can use three or four word to login

docker exec -it xxxooo /bin/sh or /bin/bash Exit CTRL + P CTRL + Q
docker exec -it xxxooo geth attach ipc://root/.ethereum/devchain/geth.ipc

=====================

======login geth======
xxxooo is path, so "find / -name geth.ipc"

geth attach ipc:./xxxooo/geth.ipc

eth.accounts have account?
eth.mining can mining?
eth.blockNumber mining?
eth.getBalance(eth.accounts[0]) have ether coin?
