1 功能需求

1) Docker运行环境.

2) 以太坊的环境部署.

3) 节点断开网络连接.

4) 节点恢复网络连接.

2 步骤实施

2.1 Docker网络配置

Default Networks

$ docker network ls

Create Network

$ docker network create -d bridge --subnet 172.25.0.0/16 eth-network

Inspect Network

$ docker network inspect eth-network

2.2 Ethereum环境部署

Pull Ethereum Image

$ docker pull ethereum/client-go

Create Ethereum Node

$ docker run -it -d --name eth-node --network eth-network -p 30303:30303 -p 8545:8545 ethereum/client-go --dev console

Geth JavaScript Console

$ docker attach eth-node

2.3 节点断开网络

Disconnect Network

$ docker network disconnect eth-network eth-node

2.4 节点连接网络

Connect Network

$ docker network connect eth-network eth-node
